Wall Running help
I want to make wall running mechanics in my game, I was somewhat successful but I have some inconsistencies with the jumping, one time it jumps to the side really fast and other times it jumps really slow, also sometimes it detects that it is wall running after I jump off a wall. Would really appreciate the help :)
private Rigidbody rb;
private PlayerController controller;
public Transform playerBody;
public float minJumpHeight;
public float wallRunGravity;
public float wallRunJumpForce;
public float wallRunSpeed;
private Vector3 wallRunJumpDirection;
public bool isWallRunning;
private bool wallIsThere;
private bool isJumping;
private void Awake()
{
rb = GetComponent<Rigidbody>();
controller = GetComponent<PlayerController>();
}
private void Update()
{
isJumping = Input.GetButton("Jump");
}
void FixedUpdate()
{
if (CanWallRun())
{
if (wallIsThere)
{
isWallRunning = true;
StartWallRun();
}
else
{
isWallRunning = false;
StopWallRun();
}
}
else
{
isWallRunning = false;
StopWallRun();
}
}
bool CanWallRun()
{
return !Physics.Raycast(playerBody.position, Vector3.down, minJumpHeight);
}
void StartWallRun()
{
rb.useGravity = false;
rb.AddForce(Vector3.down * wallRunGravity);
if (rb.velocity.magnitude < controller.maxSpeed && Input.GetAxisRaw("Vertical") > 0)
rb.AddForce(playerBody.forward * wallRunSpeed * Time.deltaTime);
if (isJumping)
{
wallIsThere = false;
rb.velocity = new Vector3(rb.velocity.x, 0f, rb.velocity.z);
rb.AddForce(Vector3.up * 150f * Time.deltaTime, ForceMode.Impulse);
rb.AddForce(wallRunJumpDirection * wallRunJumpForce * Time.deltaTime, ForceMode.Impulse);
}
}
void StopWallRun()
{
rb.useGravity = true;
}
private void OnCollisionStay(Collision collision)
{
if (collision == null)
{
return;
}
for (int i = 0; i < collision.contactCount; i++)
{
if (isWall(collision.GetContact(i).normal))
{
wallIsThere = true;
}
else
{
wallIsThere = false;
}
}
}
bool isWall(Vector3 Wallnormal)
{
float wallAngle = Vector3.Angle(Vector3.up, Wallnormal);
wallRunJumpDirection = transform.up + Wallnormal;
return wallAngle == 90f || wallAngle == -90f;
}
