Chaos Vehicle - Other Pawns can push vehicle.

How do I stop vehicles being pushed by pawns? Without ignoring the pawns on collision. I think it’s because of simulating the physics which i need otherwise the chaos vehicle won’t work.

If player walks into front of the car, it gets pushed like its made from paper.

I tried changing mass to high number, which little helped, but still player can push the car, and with high mass, the vehicle won’t move anymore.

I tried to use the official Epic’s template vehicle, which did the same thing.

if anyone has experience with this problem or with chaos vehicles, I’d be glad for some advice.

a video of my issue:

Hi,
did you tried to reduce the Push Force Factor or disable Physics Interaction to test in the Character Movement Component of the Pawn?

Optional:
You have to edit the Physics Mass from the Physics Asset of the Vehicle(Mesh) to have effect on the Push force from the Pawn.

Also dont forget to go to your Vehicle Movement Component and setup the Wheel Trace Collision Responses for Pawn to ignore if you got the problem that you still push the Vehicle.

Thats how it worked out for me :stuck_out_tongue:

Thanks for responding!

I completely disabled Physics Interaction for player movement.

I tried changing the mass of the physical asset of the vehicle mesh, which did nothing. (i tried values like 3000, 16500.)
I also tried changing mass for wheels, but nothing happened.

Wheel Trace Collision Responses for Pawn is set to ignore.

Still, player can push vehicles

One thing that surprises me is that it worked for you. I think I’ll rewrite the whole movement to my own. Because now, I’m using the Add Movement Input node.

Anyway possible “fix”:
I found a way to prevent this situation. I have an overlap sphere around the player, and if a vehicle enters this sphere, player gets knocked down with simulating physics. Which doesn’t do anything to the vehicle at all.
