A Chassis Errors

Why does A Chassis Errors have so many warning in studio, but not in game, I want to remove these warnings from studio, is that possible?

Hey,
change the density value from 0 to .01 in the chassis initialization script, it should be around line 70.

“JointService is deprecated…”
:MakeJoints() is no longer supported, so you have to manually weld the parts.
MakeJoints()

Thanks! It worked but I have these warinings now.

you’re using tonumber() on a nil value.
and makejoints is the same as already answered
