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.

new Drawable(): Drawable
Returns Drawable

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
- Defined in drawables/drawable.ts:34

`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 is reduced performance, because this object won't benefit from tile-based rendering.
Parameters
- target: vec2
Returns number
- Defined in drawables/drawable.ts:24
