Why AssemblyLinearVelocity Doesn't Throw Object And AssemblyLinearVelocity.Magnitude Doesn't Work?

I tried to re-create Sci-Fi MedVac 4300 then it doesn’t work

Part:Destroy()
MedpackClone:Destroy()

Heres the result:

I’ve had similar issues, try setting assembly linear velocity after it has been parented to workspace. That did the fix for me.

I know but I tried everything also I doesnt work

#4

Oh I think I see try adding a wait before the velocity yield check. At the moment it’s spawned it the velocity is zero due to some physics engine task scheduling stuff. Probably why it’s anchored the moments it’s thrown.

#5

I think I got a solution now:

repeat 
	wait(.25)
until MedpackClone.AssemblyLinearVelocity.Magnitude < .1
