Pixel perfect detection with BaseRenderTexture

[KennethGomez]

I've seen an example of pixel perfect detection but it does not work at all with BaseRenderTexture since its resource property is always null.

How can I solve this?

Use extract in pixi to get data when you update the renderTexture, i hope its not often :) extract uses webgl readPixels operation.

However, readPixels is a slow operation that should be done in the end of frame, that's why renderTexture's are not suited for hit detection.
