Question by Daniel G · Aug 28, 2013 at 02:45 AM · raycastingissuewheel collider

Raycasting, For Tire Effect, Glitching at HighSpeeds!

Hello, So here is my problem and I am pretty sure this is an easy fix, I have a RayCasted Graphical Tire Representation that when at high speeds the tire returns to Zero Suspension (Center of Wheel Collider) and back down to touching the ground rapidly and randomly.

I Know a bit about RayCasting, but I need some expertise.

Thanks,

Daniel

Any Ideas?

Put all Physics stuff in to FixedUpdate. The fixed time step works better with physics than Update which updates per frame and is variable with framerate. If you are still having issues try changing the Fixed Timestep in Project Settings -> Time which affects the time taken between updates of FixedUpdate.

Failing that you'd need to post the code in question

Well, I will answer it I guess! So Always put your physics calculations in fixed update as it happens per frame unlike update that can happen multiple times per frame. So in my case my RayCast was not being sent some frames because it did its calculation in between frams instead of during the frame!

Hope this helps, Daniel
