Thanks, it looks like it works
I have 2 (minor) questions thought :
1) It appears that in single player i can burn the grass but not in multiplayer. Is there a reason to that ?
2) With the getMovingObjectPositionFromPlayer method it works but only when i right-click near the player. Do you know if there is a way to extend the distance ?
If not, no problem, i can still work with that !!
Anyway, thank you
