Description:

The Restore WebGL Event.

This event is dispatched by the WebGLRenderer when the WebGL context is restored.

It is dispatched after all WebGL resources have been recreated. Most resources should come back automatically, but you will need to redraw dynamic textures that were GPU bound. Listen to this event to know when you can safely do that.

Context can be lost for a variety of reasons, like leaving the browser tab. The game canvas DOM object will dispatch webglcontextlost. All WebGL resources get wiped, and the context is reset.

Once the context is restored, the canvas will dispatch webglcontextrestored. Phaser uses this to re-create necessary resources. Please wait for Phaser to dispatch the RESTORE_WEBGL event before re-creating any resources of your own.
