MeshRenderer

class for the mesh renderer

Type	Name	Interface Description
Variables	mainMaterial: Material | null	• Function: Get the first shared material used by the MeshRenderer. Returns The first shared material used by the MeshRenderer, or null if none is assigned.
Variables	mainPass: Pass | null	• Function: Retrieves the main pass from the object's shared material. Returns The first pass of the shared material, or null if no passes are available.
Variables	mesh: Mesh	• Function: Retrieves the mesh associated with the MeshRenderer. Returns The mesh object.
Functions	constructor()
Functions	getBoundingBox(): AABB	• Function: Retrieves the axis-aligned bounding box (AABB) for this mesh renderer. Returns The axis-aligned bounding box representing the bounds of the mesh.

Examples

constructor()

let obj = new APJS.MeshRenderer();

Use Case

Change a 3D object's material color at runtime via MeshRenderer.mainMaterial

@component()
export class MaterialColorChange extends APJS.BasicScriptComponent {
  @serializeProperty
  private targetColor: APJS.Color = new APJS.Color(1, 0, 0, 1);

  onStart(): void {
    this.applyColor(this.targetColor);
  }

  private applyColor(color: APJS.Color): void {
    const renderer = this.getSceneObject().getComponent("MeshRenderer") as APJS.MeshRenderer;
    // Use mainMaterial for single material access
    // Use setVector (NOT setVector4 — it doesn't exist)
    if (renderer && renderer.mainMaterial) {
      renderer.mainMaterial.setVector("_AlbedoColor", new APJS.Vector4f(color.r, color.g, color.b, color.a));
    }
  }

  onDestroy(): void {}
