Need help with WeldConstraint and VectorForce

#1

Hello! I’m trying to move a part using a VectorForce and even when I weld another part on it the system works fine. There is a problem when I try to weld the HumanoidRootPart to the VFpart (Vector Force part)

welding a part to the VFpart:
working

welding the HumanoidRootPart to the VFpart:
not working

any help is appreciated!

Just up the vectorForce’s force. The character has mass which is weighing down the part, so if the force is too small it won’t move at all. You’ll start seeing movement at 25,000 force on a vector.

Thanks for the help, but how do you know the exact force you have to exert on a part to make it move??

Trial and error, buddy… Trial and error ;-;…

Or you could do the nerd way, and do getMass() for the parts of your body, do some weird gravity calculations to figure out what to negate or something like that, but at that point trial and error is faster.

If you use, a force like bodyVelocity though all you have to do is set maxForce to

bv.MaxForce = Vector3.new(math.huge,math.huge,math.huge)

That ignores mass, then you can set the velocity to a smaller more exact speed
