Hi guys,

Does anybody know what the texture_dx and texture_dy mean in the texturedPolygon function in SDL2_gfx framework?

The description is really cryptic for me.

Thanks.

It's the position where the polygon will be drawn.

Wait, what?

So what does the vx and vy arrays represent? I thought that was the vertices in screen coordinates.

Ignore what I just said. I was wrong. The shape made up of vx and vy cuts out a piece of the texture but what part depends on texture_dx and texture_dy.
