So I made a custom Critter that is 1005 functional, until I edit the "collisionpolly" to make it sitting in the ground. The current setting I have is this. Code: "collisionPoly" : [ [-0.5, 0.2], [0.5, 0.2], [0.5, 1.2], [-0.5, 1.2] ], But this makes the critter unable to detect the player and fly away for some odd reason. But if I set it to Code: "collisionPoly" : [ [-0.5, 0.0], [0.5, 0.0], [0.5, 1.2], [-0.5, 1.2] ], It's COMPLETELY fine and flies away whenever I get near it. But the problem then is it isn't buried in the ground like I want and it looks weird. If anyone could help me figure this out that would be appreciated.
