When i move too quickly with my viewmodel i get flinged or flown away

Help and Feedback Game Design Support
#1

I’m currently making a simple fps framework so I will know how to make ones in the future and I have pretty much everything set.

Whenever I have the gun equipped and move too fast or maybe have my mouse do an entire seizure, it just flings me or sends me across the map.

I’ve tried checking that everything has cancollide off and isnt anchored, and that applies to everything currently, all my scripts seem to work fine and have no issues.

I think you have some objects in the viewmodel that are can collide on that’s why

Because rig pieces like arms and stuff get automatically can collide on when you run the game

You can fix this by creating a collision group that doesn’t collide with anything so that when can collide is on it still won’t collide

#3

I made a collision group, picture this (what I did) the viewmodel group holds the viewmodel parts and the character group holds the character parts, should this work?

#4

I think so if the problem is the can collide which probably is

#5

It didn’t work sadly, :frowning: how does the CollisionGroupId property work?

#6

You can just select the arms and click the plus icon next to the collision group in the collision group editor

Make all parts of the tool Massless. If they have any Density they throw off your player physics.
