Base class of every drawable object.

To create your own drawables, you need to subclass from this.

Although lights are also subclasses of Drawable, you cannot create your own light sources.

Properties

Static Readonly descriptor

descriptor: DrawableDescriptor

This should be defined in inherited classes.

Methods

Protected Abstract getObjectToSerialize

  • getObjectToSerialize(transform2d: mat2d, transform1d: number): any
  • Return the values that should be given to the shaders through uniform inputs.

    Parameters

    • transform2d: mat2d

      position-like properties should be transformed by this matrix before being returned.

    • transform1d: number

      scalar properties should be transformed by this number before being returned.

    Returns any

Abstract minDistance

  • minDistance(target: vec2): number
  • The lower bound of the distance between the target and the object.

    It can return 0 by default, the only consequence of this, is a reduced performance. Because this object won't benefit from tile-based rendering.

    Parameters

    • target: vec2

    Returns number
