I am trying to make something with java libgdx (2D). One thing that I can't figure it out is how to check mouse intersection with (fore example) isometric textures that are not rectangle shaped images. I found something about pickingColorPicking algorithm in libgdx, but I can't find any docs about how to use it. Any ideas?
you can use the pixmap.getPixel(x,y) function to find the color value at a certain pixel. To do collision checking, you could check the alpha value of that pixel. If it isn't zero, there is a collision
