collision-detection

How can i detect clicks on a texture (will be a button in my game) that has a form of a triangle or circle. I know only the rectangle solution where u can use the positions + the width/height but this dont work for that because clicks will be detected at the transparent pixels.

I heard of pixel-perfect collision is it the right way for this?

It would be great if someone can give me a example for such a solution or other.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
