Ich glaube , ich löste es durch eine Änderung Physics.Raycastan Physics.SphereCastim Skript ThirdPersonCharacter.cs. Aber es muss noch getestet werden.
bool condition = Physics.SphereCast(
m_Capsule.transform.position + m_Capsule.center + (Vector3.up * 0.1f),
m_Capsule.height / 2,
Vector3.down,
out hitInfo,
m_GroundCheckDistance
);
Ich musste auch diese Zeile auskommentieren, die den m_GroundCheckDistanceWert änderte , ansonsten gab es bei einigen Modellen ein komisches Gleiten:
void HandleAirborneMovement()
{
// apply extra gravity from multiplier:
Vector3 extraGravityForce = (Physics.gravity * m_GravityMultiplier) - Physics.gravity;
m_Rigidbody.AddForce(extraGravityForce);
//m_GroundCheckDistance = m_Rigidbody.velocity.y < 0 ? m_OrigGroundCheckDistance : 0.01f;
}
Und ich wechselte m_GroundCheckDistance = 0.1f;zu m_GroundCheckDistance = m_OrigGroundCheckDistance;:
void HandleGroundedMovement(bool crouch, bool jump)
{
// check whether conditions are right to allow a jump:
if (jump && !crouch && m_Animator.GetCurrentAnimatorStateInfo(0).IsName("Grounded"))
{
// jump!
m_Rigidbody.velocity = new Vector3(m_Rigidbody.velocity.x, m_JumpPower, m_Rigidbody.velocity.z);
m_IsGrounded = false;
m_Animator.applyRootMotion = false;
m_GroundCheckDistance = m_OrigGroundCheckDistance;
}
}
