My tires spin perfectly the way I want them too, however I can seem to find a straightforward tutorial or free piece of code (in C#) that can help me Turn the tires in the same angle as my wheel colliders.
I would appreciate if someone could point me in the right direction! I’ve been searching for about 3 hours and all I can seem to find are people asking how to rotate the tires which is something I have already figured out.
So your tire objects control their rotation on the Z and you want to set their rotation on the Y to match the wheel collider so they turn left and right?
Should just be:
Quaternion tireRotation = tire.transform.rotation;
Quaternion colliderRotation = collider.transform.rotation;
tire.transform.rotation = Quaternion.Euler(tireRotation.eulerAngles.x, colliderRotation.eulerAngles.y, tireRotation.eulerAngles.z);
My code is as follows but I got the following error:
Assets/Scripts/HarvMovementScript.cs(17,35): error CS0236: A field initializer cannot reference the nonstatic field, method, or property HarvMovementScript.WheelsFL' & Assets/Scripts/HarvMovementScript.cs(18,39): error CS0236: A field initializer cannot reference the nonstatic field, method, or property HarvMovementScript.WheelColliderFL’

Move these two lines:
Quaternion tireRotation = WheelsFL.transform.rotation;
Quaternion colliderRotation = WheelColliderFL.transform.rotation;
Down to just before this line:
WheelColliderFL.transform.rotation = Quaternion.Euler(tireRotation.eulerAngles.x, colliderRotation.eulerAngles.y, tireRotation.eulerAngles.z);
Quaternions are structs (value types), so you can’t store references to them like you can classes (reference types).
