* Phaser - DynamicTexture
|

*
|
||||
* A DynamicTexture can be thought of as a mini canvas into which you can draw anything.
|
||||
* Game Objects can be assigned a DynamicTexture, so when they render in the world they do so
|
||||
* based on the contents of the texture at the time. This allows you to create powerful effects
|
||||
* once and have them replicated across as many game objects as you like.
