Mouse Event on Transparent Colour

I modified captaincomic's Mouse Event on Collision Shape to serve the same purpose. It works by detecting if the clicked pixel is transparent and if so, it returns a false. So far it's working well and does the same job as the original.

Are those behaviors still on forge ? I looked for them but my search returned with 0 matches =/

Behaviors are split between 2.2 and 3.0 on the StencylForge.
