Do you know how the Minecraft mod Figura works?

Figura is a Minecraft mod that allows players to create and use custom 3D models for their player avatar, also known as a player model, in Minecraft. It is built for the Fabric mod loader and requires installation alongside other Fabric mods. Here's a brief overview of how Figura works:

1. Installation: First, you'll need to install the Fabric loader and Fabric API. Once you have done that, you can download and install the Figura mod by placing the mod's .jar file into the 'mods' folder in your Minecraft directory.

2. Custom Models: Figura allows you to import custom 3D models created in various 3D modeling software (e.g. Blockbench) into the game. You will design and create your custom player model with the Minecraft's base model in mind. You can use features like animations, emissive textures (glowing elements), and transparency (semi-transparent textures).

3. Exporting and Uploading: Once your model is ready, you can export it as an .obj file, and create a .zip file containing your exported model, textures, and a Lua script that's responsible for the custom animations. You can name it my_model.figura and place it in the 'Figura' folder in your Minecraft directory. Figura will then load this file and allow you to use the custom model in game.

4. In-Game Use: Once you have imported and activated your custom model, Figura will allow you to use it in-game as your player avatar. Note that using custom models when playing on servers may require permission from server administrators.

5. Sharing: Figura also allows you to share your custom models with others on the server by enabling them to download your model data when they see your custom avatar. This way, other players can enjoy the custom models you create without having to download and install them manually.

Remember that Figura is a mod, so it's essential to know that its compatibility with other mods and Minecraft's future updates is not guaranteed. Always back up your save files and profiles before installing or updating mods to avoid potential issues.

Figura mod uses Lua scripting language to handle custom animations and other features for your custom player models. I will give you an introduction to Lua scripting in Figura and some examples to get you started.

1. Create a Lua script: When creating your custom model, you will need to create a .lua file for your animations. Name your script file "script.lua" and include it in your .zip file with your model and textures.

2. Basic Structure: Open script.lua in a text editor, and set up the basic structure for a Figura Lua script:

function setup()
   -- Setup code goes here
end

function tick()
   -- Animation code goes here
end

The setup() function is called when the script is loaded, and the tick() function is called once for each game tick (20 times per second) to handle animations.

3. Accessing Model Parts: To access and animate model parts, you'll need to reference the names of the parts you defined in your 3D modeling software. Assuming you have a part named "head":

local head = model['head']

4. Transformations: You can manipulate the position, rotation, and scale of model parts using Lua. Here's an example of how to change the rotation of the "head" part:

function tick()
   head.setRotation(0, game.tick * 2, 0)
end

This will make the head rotate around the vertical axis at a constant speed.

5. Accessing Player Data: You can access various data about the player, like health, hunger, or velocity. For example, to access the player's health:

local health = player.getHealth()

6. Conditional Animations: Let's say you want to change the head's rotation when the player is sneaking. You can use an if statement to check if the player is sneaking and apply the appropriate rotation:

function tick()
   if player.isSneaking() then
      head.setRotation(0, game.tick * 4, 0)
   else
      head.setRotation(0, game.tick * 2, 0)
   end
end

So, when the player is sneaking, the head will rotate twice as fast.

7. Customizing Animations: You can create more complex animations by combining different transformations, conditional statements, and player data. Explore the Lua documentation (https://www.lua.org/manual/5.1/) and Figura wiki (https://figura.dev/wiki/Main_Page) to learn more about the possibilities and expand your knowledge.

Remember, the Figura mod and Lua scripting in it might have some limitations compared to other professional animation tools. However, it can still provide a lot of customization and creativity for your Minecraft player models.

Figura does not currently have built-in physics simulation support. However, you can simulate basic physics using Lua scripting and implement a simple custom physics-like behavior for your model parts.

Here is an example of simulating a simple pendulum-like behavior for a model part using Lua in Figura:

1. Define the model part and any necessary variables in the setup() function:

local pendulum_arm

local pendulumSpeed = 0 -- Angular speed of the pendulum
local pendulumAcceleration = 0 -- Angular acceleration of the pendulum
local gravity = 0.1 -- Artificial "gravity" affecting the pendulum

function setup()
  pendulum_arm = model['pendulum_arm'] -- Use the proper part name from your model
end

2. Implement a basic pendulum physics simulation in the tick() function:

function tick()
  local currentRotation = pendulum_arm.getRotationY() -- Assuming the pendulum swings in the Y-axis

  -- Calculate the current angular acceleration using the current rotation and "gravity"
  pendulumAcceleration = -math.sin(math.rad(currentRotation)) * gravity

  -- Update the angular speed of the pendulum using the calculated acceleration
  pendulumSpeed = pendulumSpeed + pendulumAcceleration

  -- Update the rotation of the pendulum arm based on the updated speed
  pendulum_arm.setRotationY(currentRotation + pendulumSpeed)

  -- Apply some damping to the pendulum speed to simulate air resistance/friction
  pendulumSpeed = pendulumSpeed * 0.99
end

Now, you have a basic physics simulation that will make your pendulum_arm part swing back and forth like a pendulum. You can adjust the gravity value to change how fast the pendulum swings or the damping factor (0.99) to control how quickly the pendulum loses its momentum.

Please note that this example provides a simple, physics-like behavior and not a fully accurate physics simulation. However, this should give you an idea of how to create basic custom physics behavior in Figura using Lua scripting. Feel free to expand and experiment with more advanced physics behaviors using similar techniques.

Here's a modified version of the provided prompt with explanations of its' logic:

local root = models.model.root
local skirt = models.model.World.skirt
local vertices = {}
local links = {}
local spheres = {
    {
        parent=root.LeftLeg,
        position=vec(0,-4,0),
        radius=4/16
    },
    {
        parent=root.RightLeg,
        position=vec(0,-4,0),
        radius=4/16
    },
    {
        parent=root.Body,
        position=vec(0,-6,0),
        radius=6/16
    },
}

-- Log all vertices in the skirt part
logTable(skirt:getAllVertices())

-- Initialize vertices, links, and fixed points
local verts = skirt:getAllVertices()[0]
local parentToWorldMatrix = root.Body:partToWorldMatrix()
for i, v in ipairs(verts) do
    local nv = verts[(i%4==0) and i-3 or i+1] -- Neighbor vertex
    local vPos = v:getPos() -- Current vertex position

    -- Add vertex to the vertices table and set initial values
    if vertices[vPos:toString()] then
        table.insert(vertices[vPos:toString()].vertices, v)
    else
        vertices[vPos:toString()] = {vertices={v}, position=vPos:copy(), oldPosition=vPos:copy(), velocity=vec(0, 0, 0), fixed=false, targetPosition=v:getPos()}
    end

    -- Add a link between the current vertex and its neighbor if it doesn't already exist
    local valueExist = false
    for i, v in ipairs(links) do
        if (v.a==vPos and v.b==nv:getPos()) then
            valueExist = true
        end
    end
    if not valueExist then
        table.insert(links, {a=vPos, b=nv:getPos(), length=(vPos-nv:getPos()):length()})
    end

    -- Set fixed points with a specific Y position
    if vPos.y >= -10 then
        vertices[vPos:toString()].fixed=true
    end
end

-- Initialize a variable for face direction
local face = 0

-- Initialize a variable for the last world time
local lastTime = world.getTime()

-- POST_RENDER event that handles the skirt's movement and collision with defined spherical objects
events.POST_RENDER:register(function (delta, context)
    -- Check if the player is host and in first-person, then hide the skirt
    if (host:isHost() and renderer:isFirstPerson()) then
        skirt:setVisible(false)
        return
    end
    skirt:setVisible(true)

    -- Calculate elapsed time and update the parentToWorldMatrix
    d = world.getTime()+delta - lastTime
    lastTime = world.getTime()+delta
    parentToWorldMatrix = root.Body:partToWorldMatrix()

    -- Iterative process to update vertices positions, check for sphere collision, and maintain link length constraints
    for iter = 1, 3 do
        for i, v in pairs(vertices) do
            -- Update old and current vertex positions, add damping and apply gravity
            if iter == 1 then
                local p = v.vertices[1]:getPos() -- Get the actual vertex position
                local change = p-v.oldPosition
                v.oldPosition = v.position
                v.position = p
                v.position:add(change*0.99) -- Damping factor
                v.position:add(vec(0, -0.075*d, 0)) -- Gravity
            end

            -- Sphere collision check and position update
            for _, sphere in ipairs(spheres) do
                local center = sphere.parent:partToWorldMatrix():apply(sphere.position)
                local dif = v.position/16-center
                particles:newParticle("bubble", v.position)
                if dif:length() < sphere.radius then
                    v.position = (center+dif:normalized()*sphere.radius)*16
                end
            end
        end

        -- Enforce link length constraints
        for i, l in ipairs(links) do
            local a = vertices[l.a:toString()]
            local b = vertices[l.b:toString()]
            local dif = a.position - b.position
            local stretch = math.clamp((dif:length() - l.length) / l.length, -1, 1)

            if stretch > 0 then
                a.position:sub(dif*stretch/2)
                b.position:add(dif*stretch/2)
            end
        end

        -- Update and apply vertex positions
        for i, v in pairs(vertices) do
            if v.fixed then
                v.position = parentToWorldMatrix:apply(v.targetPosition)*16
            end
            for _, vertex in ipairs(v.vertices) do
                vertex:pos(v.position)
            end
        end
    end
end)

-- Update face direction in the TICK event
events.TICK:register(function ()
    face = face + 0.05
end)

The code sets up the behavior for a skirt-like object and simulates its movement, treating it like a collection of connected vertices and links. Constraints ensure the links don't stretch, and collisions with spherical objects, such as legs and body, are handled to keep the skirt from intersecting with them.

Certainly! Here's a more exhaustive breakdown of each segment of the provided prompt:

1. Initialize variables and create sphere objects for collision purposes.

local root = models.model.root
local skirt = models.model.World.skirt
local vertices = {}
local links = {}
local spheres = {
    {
        parent=root.LeftLeg,
        position=vec(0,-4,0),
        radius=4/16
    },
    {
        parent=root.RightLeg,
        position=vec(0,-4,0),
        radius=4/16
    },
    {
        parent=root.Body,
        position=vec(0,-6,0),
        radius=6/16
    },
}

2. Log all vertices in the skirt part.

logTable(skirt:getAllVertices())

3. Iterate through skirt vertices to accomplish the following:

• Create vertices and neighbor vertices data structures.
• Initialize links between vertices.
• Set fixed vertices to prevent certain vertices from moving.

local verts = skirt:getAllVertices()[0]
local parentToWorldMatrix = root.Body:partToWorldMatrix()
for i, v in ipairs(verts) do
    ...
end

4. Initialize a variable for face direction.

local face = 0

5. Initialize a variable to store the last world time. This value will be used to calculate elapsed time.

local lastTime = world.getTime()

6. Register the POST_RENDER event function. This function is executed every frame and handles the following:

• Hide the skirt when the player is in the first-person view.
• Calculate the elapsed time and update the parentToWorldMatrix.
• Perform the iterative process to update vertex positions (3 iterations).
  • Update old and current vertex positions based on velocity, damping, and gravity.
  • Check for collisions with defined sphere objects (legs and body) and adjust vertex positions accordingly.
  • Enforce link length constraints by adjusting positions of connected vertices if they get too far apart or too close together.
  • Fix the positions of specific vertices and apply updated positions to the model.

events.POST_RENDER:register(function (delta, context)
    ...
end)

7. Register the TICK event to update the face direction. This event is executed every game tick (20 times per second).

events.TICK:register(function ()
    face = face + 0.05
end)

In summary, the code snippet provided initializes a simple cloth simulation for a skirt-like object using vertices, links, and an iterative process for position updates, link constraints, and collisions with defined sphere objects (legs and body). Additionally, visual adjustments are made, such as hiding the skirt in the first-person view, and the face direction is updated during the game tick event.

In this code snippet, the author defines a table (an associative array) called anims which contains multiple functions for animating a character model in various states such as standing, crouching, swimming, etc., using Figura mod's API. The functions take into account the properties such as player's velocity, body velocity, and base rotation to adjust the character model's rotation for smooth and realistic animations. Let's break down the functions and their roles:

1. STANDING function: This function defines the character's standing animation, taking player_vel, body_vel, base_rot, and inWater as its parameters.

It modifies the rotation of the character model based on player's velocity, body velocity, and an oscillating function using the sine function. Additionally, it checks if the character is in water or is partially submerged and adjusts the base_rot.x.

2. CROUCHING: The code defines crouching animation as the same as the standing animation by assigning the string "STANDING" to the "CROUCHING" key.

3. SWIMMING function: This function handles the character's swimming animation, taking the same input parameters as the STANDING function. Depending on whether the character is submerged or not, it adjusts the character's model's rotation accordingly for crawling or swimming.

4. FALL_FLYING function: This function adjusts the character's model rotation when falling or flying by considering body velocity as its input.

5. SPIN_ATTACK function: This function manages the character's spin attack animation by adjusting the rotation around the Y-axis.

6. SLEEPING function: This function defines the character's sleeping animation, and it doesn't require any parameters. It sets the character model's rotation to a predefined sleep pose based on the config.sleep_pose values. The character model faces either left or right randomly when sleeping, depending on the sleep_side value.

7. SIT function: This function takes care of the sitting animation, taking the same input parameters as the STANDING function. It checks if the character is in water, and depending on that, it adjusts the rotation of the character model to properly represent a sitting pose on land or in water.

These functions within the anims table can be used to animate a character model depending on the character's state within the context of the Figura mod in Minecraft. To implement these animations, you would call the appropriate function from anims based on the player's current state and apply the returned rotation to the character model.

This code snippet demonstrates the implementation of a more advanced simulation for a Minecraft skirt-like object using the Figura mod's API. It utilizes an iterative process to update vertex positions, enforce link constraints and handle collisions with both spherical bodies and blocks in the world. Here's a breakdown of each segment in the code:

1. Initialize the model parts, empty structures for vertices, links, and spherical bodies for collision purposes (e.g. legs and body):

local root = models.skirt.root
local skirt = models.skirt.World.skirt
local vertices = {}
local links = {}
local spheres = {
...}

2. Define a function to check if a rectangle intersects with a point, but leave it empty for now as it's not used in the code:

local function rectIntersectsPoint(a, b, p)
end

3. Define a function, solveRectPointCollision(), to check and solve collisions with axis-aligned bounding boxes (rectangles) in the game:

local function solveRectPointCollision(a, b, p)

4. Log all vertices of the skirt part:

logTable(skirt:getAllVertices())

5. Iterate through skirt vertices and create vertices, neighbor vertices, and links between vertices. Also, set fixed points for vertices:

local verts = skirt:getAllVertices()["skirt"]
...
for i, v in ipairs(verts) do
...
end

6. Initialize a variable to store the last world time to later calculate elapsed time:

local lastTime = world.getTime()

7. Register the POST_RENDER event. This function is executed every frame and handles the following tasks:
   • Show or hide the skirt based on if the player is in the first-person view.
   • Calculate elapsed time and update the parentToWorldMatrix.
   • Execute the iterative process (3 iterations) to:
     • Update vertex positions based on velocity, damping, and gravity.
     • Check and solve collisions with defined sphere objects.
     • Check and solve collisions with blocks in the world.
     • Enforce link length constraints between connected vertices.
     • Update and apply new vertex positions to the model.

events.POST_RENDER:register(function (delta, context)
    ...
end)

This code creates a more complex simulation of a skirt-like object in Minecraft, handling collisions not only with spherical objects (legs and body) but also with in-game blocks. The animation smoothly processes and updates the position constraints and collision handling while ensuring the skirt object doesn't intersect with or clip through other in-game objects.

Certainly! I'll walk you through creating a custom model using Blockbench and applying a similar cloth physics-like behavior for a cape using Lua scripting in Figura mod. Here's a step-by-step guide:

1. Create a custom model in Blockbench

   • Open Blockbench (https://www.blockbench.net/) and create a new "Modded Entity" model.
   • Design your custom character model, with a cape-like object consisting of multiple segments for better simulation. Each segment should be a separate cuboid. The more segments you have, the smoother the cape will move, but it will also increase the complexity of the simulation.

2. Export & Install the Model in Figura

   • Export the model as an .obj file.
   • Create a .zip file containing the exported model, textures, and a Lua script called "script.lua" (which we will create in the next step). You can name it my_model.figura and place it in the "Figura" folder in your Minecraft directory.

3. Write a Lua Script for the Cape Physics

   • Create a new "script.lua" file and define the cape segments, vertices, and spheres for collision purposes (which may be the character's body or head).
   • Using the code provided in previous questions as inspiration, write a custom Lua script to simulate simple cloth-like physics for your cape model. This would involve updating vertex positions, enforcing link length constraints, and handling collisions with spherical objects (such as body or head).
   • You can further adapt the code to also consider collisions with in-game blocks while moving, for a more realistic simulation.

4. Applying the Script in Minecraft using Figura

   • Ensure the Figura and Fabric API mods are installed and running in your Minecraft installation.
   • Place the script.lua file inside the .zip file created in Step 2, and in the Figura mod folder. The custom model and script should be automatically loaded when you start the game.
   • Your character model in-game will now have a custom cape with physics-like behavior applied.

Remember that the detailed behavior of the cape will heavily depend on how you have designed your cape model in Blockbench, and how you modify the Lua scripting to work with that specific design. Experiment with different designs and physics settings until you achieve the desired look and behavior for your cape.

Please also note that this method focuses on creating simple cloth-like physics. It won't provide highly accurate physics simulation found in professional game engines, but it can still be an engaging way to add more style and dynamic animations to your Minecraft character model.

Sure! Here's a basic example of a tail-like animation in Figura using Lua, without direct key-frame animations. The tail will consist of multiple segments, and the script will adjust their rotations to create a smooth and dynamic tail movement based on the player's movement.

1. First, create the tail model in Blockbench as a part of your custom character model. For this example, let's assume you have five tail segments named tail1, tail2, tail3, tail4, and tail5.

2. Next, create the "script.lua" file for your custom model and write the following code:

-- Define tail segments, angles and step
local tail_segments = {
    model["tail1"],
    model["tail2"],
    model["tail3"],
    model["tail4"],
    model["tail5"]
}

local angle_spread = math.rad(20) -- angle to spread the tail segments
local angle_stepdown = math.rad(10) -- angle stepdown from
