resolve error

E 0:00:50.075 recover_from_penetration: Condition "shape_idx < 0 || shape_idx >= cs->getNumChildShapes()" is true. Returned: false <C++ Source> modules/bullet/space_bullet.cpp:1241 @ recover_from_penetration() <Stack Trace> v2lion.gd:315 @ _physics_process()

Line 315 is: velocity = move_and_slide(velocity)

preceded by:

direction = direction.normalized() velocity = velocity.linear_interpolate(direction speed, acceleration delta)

How do I resolve this error? What is it about? My code throws it up thousands of times when running.

Thanks

Same project .. no such reported error in Godot 3.1.1.

Only Godot 3.2

Maybe the move_and_slide function needs more arguments passed? I know most cases that use move_and_slide include another Vector3 for the up direction, something like velocity = move_and_slide(velocity, Vector3.UP), so maybe when it is missing the up direction it throws that error. Though if that is the case, that would suggest is is an undocumented requirement...

Hi noob51beta, did you check that velocity is a valid Vector3. Vector3 can be (nan,nan,nan) wich mostly throws errors

The second vector is only used for determing if the collision is a wall ceiling or ground and has a default value.

Hi TwistedTwigleg and klaas. Thank you for your input on this. It is looking like the issue is “something wrong at the design stage in my design” that wasn’t flagged up as an error in Godot 3.1.1. When in my project for example lionesses spawn lioness cubs, the kinematic body node itself the spawn point, the errors can be in abundance then as the cubs move from the vicinity of their mother the error reports subside. I think the error occurs when kinematic bodies (repeatedly?) try and occupy the same space – an occasional and regular outcome the way I have written my code. This I think might be the reason for “@ recover_from_penetration()” part of the error message. My movement code needs a substantial edit / rewrite in any event – probably the way for me to go to eliminate the error or see it a much rarer thing.

I had the same error when the player collision box entered another object which was supposed to be on a different collision layer. The player is a KinematicBody on layer 1 (mask set to this layer only) with defined CollisionShape and the object is a similar KinematicBody but on the layer 2 (mask also set only for this layer). I could not find any error so I've tried moving it to a different layer ... and it worked. But the best part is: After moving it to the original layer the project works with no errors again.

That sounds like a metadata bug.
