Hi guys, I’m new.
This my question. E.g:
I was insert a PNG as a sprite, and I want to engine detect mouse hover the map ( A in the pic ) in sprite and do something, not include other transparent place( B in the pic ). Problem is the engine just detct mouse hover whole sprite ( inclue transparent place), How to fix it ?
Thanks !
There is not a way in the engine to only have it detect nontransparent pixels of a sprite.
Your best bet would to update its collision box to be something close, then attach a small sprite to your mouse cursor point via events.
Note that collision boxes can only be convex, so you may need to add multiple polygons to the sprite.
ok, got it. Thanks a lot.
If all shapes have a different color, you can use the get color extension and get the color at the position of MouseX/MouseY position and use it to know which one you are hovering
