SgTetrahedron

Creates a tetrahedron primitive mesh.

Inherits from

SceneObject

Usage

local SgTetrahedron = require 'engine/sceneobjects/sgtetrahedron'

Reference

create

static create(self, options, parent)

Create a new tetrahedron object in the scenegraph.

Parameters

  • self
  • options (table): A table of options to fill the parameters
  • parent (SceneObject): The parent scene object to add this to

Returns

  • Promise: promise which will resolve to the created object

Example

-- Options can be omitted. This example shows the defaults,
-- only specify the ones you want different.
SgTetrahedron.create({
    active = true,
    name = "",
    transform = Transform.new(),
    layers = {0},
    tags = {},
    receiveShadow = false,
    castShadow = false,
    material = nil,
    radius = 1,
    detail = 0,
    uvScale = Vector2.new(1, 1)
})

Properties

You can access these properties directly on the object or through :get("propertyName") or :set("propertyName", value) methods.

Property Type Default Description
active Boolean true Indicates if the 3D object is currently active or inactive. When set to true, the object is active.
static Boolean false Marks the object as immovable during play. Static objects ignore transform changes at runtime and use a fixed physics collider with zero mass.
transform Transform Transform.new() Describes the object's transformation attributes including its position, rotation, and scale in the 3D space.
layers Layers [0] Defines the layers that the 3D object is part of. Layers are used for managing object interactions and visibility in the scene.
tags Tags [] Lists tags associated with the 3D object. Tags are useful for categorizing and searching objects in the scene.
receiveShadow Boolean false Determines whether the object can receive shadows from other objects. Set to true if the object should display shadows cast upon it.
castShadow Boolean false Controls whether the object casts shadows in the presence of light sources. Set to true to enable shadow casting from this object.
rendered Boolean true When disabled, the object and its descendants are not drawn, but may still simulate physics or run scripts.
radius Float 1 Distance from center to each vertex.
detail Integer 0 Subdivision level refining the tetrahedron.
uVScale Vector2d Vector2.new(1, 1) Multiplier for texture coordinates.
physicsEnabled Boolean false Turns physics simulation on or off for this object. When disabled, the object keeps its visual transform but does not participate in collisions or forces.
