Hello all!
I have been wracking my brain for weeks trying to solve this issue. Any assistance is greatly appreciated!
I’ve created a custom Rigidbody FPS controller. I need to prevent it from climbing steep slopes. Currently, when it steps onto a steep slope, it slides downwards, but since it can repeatedly step on and slide down such a slope in rapid succession, it causes a perceptible “jitter”. This is what I’m trying to prevent. I wish to use forces at the base of the slope to prevent the character from making that step onto it.
- With sufficient velocity, the
Rigidbody should still be able to
slide partway up, but after it has
slid down again, it should remain at
its base unless it runs again.
- I can’t utilize friction, because the
Rigidbody uses a frictionless
material to prevent other issues.
- Disabling forward input altogether
doesn’t work, because the character
should still slide along the base of
the slope if the input isn’t exactly
perpendicular to its base.
- Finally, force application must be
precise, as the character itself be
standing on a Rigidbody, which must
remain unaffected.
The following code is very close, but the jitter returns when there is a high approach angle:
private void SlopePreventClimb()
{
if ( !isGrounded || isSliding) return;
var hit = new RaycastHit();
var movementDir = Body.velocity.normalized;
if ( !Physics.Raycast( transform.position + ( movementDir * 0.3f ), Vector3.down, out hit ) ) return;
if (Vector3.Angle(Vector3.up, hit.normal) < 45f) return;
var force = transform.InverseTransformVector( hit.normal / Time.fixedDeltaTime * Body.velocity.magnitude);
force.y *= -1f;
Body.AddForce(force, ForceMode.Acceleration);
}
Again, I’m quite stumped. Any help would be greatly appreciated!
Thank you in advance. :)
