Thanks for your help! I made an error when writing the rights, so it wasn't able to detect the gani. So now, it throw the "shuriken" but after like half a second, the shuriken disappears and there's only the shadow left. When I tried with the "arrow.gani" the arrow was there all the time, and my gani is exactly the same, except it's single direction. Is there something I have to do with the gani to keep it visible when throwing it?
EDIT: Sorry, found my mistake.

It just worked all fine. Thanks a lot for all your help. It really helped me understand all that stuff lol.
