Push player away from the enemy
I've made my own controller for the game I'm trying to make but I've ran into some issues with it. Whenever the enemy is approaching me and I don't stop my character in time, my character teleports on top of the enemy's head.
Push away:
void OnControllerColliderHit(ControllerColliderHit hit)
{
if (hit.gameObject.GetComponent<EnemyController>())
{
Debug.Log("!");
float pushPower = 0.05f;
Vector3 pushDir = hit.transform.forward;
characterController.Move(pushDir * pushPower);
}
}
Movement:
void FixedUpdate()
{
RaycastHit hitInfo;
Physics.SphereCast(transform.position, characterController.radius, Vector3.down, out hitInfo, characterController.height / 2f);
desiredMove = Vector3.ProjectOnPlane(desiredMove, hitInfo.normal).normalized;
desiredMove = (transform.forward * Input.GetAxis("Vertical") + transform.right * Input.GetAxis("Horizontal")).normalized;
if(characterController.isGrounded)
{
moveDir.x = desiredMove.x * speed;
moveDir.z = desiredMove.z * speed;
isJumping = false;
if(Input.GetButtonDown("Jump"))
{
moveDir.y = jumpPower;
isWalking = false;
isJumping = true;
canRun = false;
}
if(Input.GetButton("Sprint") && canRun)
{
isWalking = false;
isRunning = true;
moveDir.x = desiredMove.x * runSpeed;
moveDir.z = desiredMove.z * runSpeed;
}
else
{
isRunning = false;
}
}
else
{
Falling();
}
characterController.Move(moveDir * Time.fixedDeltaTime);
}
I've decided to add a function to push player away if he's too close to the enemy but I can't really get it to work right. Right now it pushes player in the forward direction of the enemy so it works fine when you're approaching the enemy from the front, in other cases my player just teleports in front of the enemy. I wanted to push the player away to the direction he came from but I can't really think of any way to do it. Could anyone help me out with it?
You could try using Rigidbody.AddForce with Force$$anonymous$$ode.Impulse with the difference between your player and the enemy's position, something like this:
GetComponent<Rigidbody>().AddForce((transform.position - enemy.transform.position).normalized * pushAmount, Force$$anonymous$$ode.Impulse);
Now I just typed this in the comment, so there are a few things that could go wrong.. You may need to reverse the transform.position and the enemy.transform.position, just switch them around if it doesn't push you backward.
It's untested, but that could work.
Another idea is you could just simply only move your character as long as there is no collisions with an enemy. You could set your enemy's tag to a new tag called "Enemy", and do something like this:
bool isColliding;
void OnCollisionEnter(Collision col) {
if(Collision.CompareTag("Enemy"))
isColliding = true;
}
void OnCollisionExit(Collision col) {
if(Collision.CompareTag("Enemy"))
isColliding = false;
}
Now again, I probably messed it up. You may need to replace collision with collider, and make sure You OR the enemy have a rigidbody.
Good luck.
Here's the final code:
void OnControllerColliderHit(ControllerColliderHit hit)
{
if (hit.gameObject.GetComponent<EnemyController>())
{
float pushPower = 0.05f;
Vector3 pushDir = transform.position - hit.transform.position;
characterController.Move(pushDir * pushPower);
}
}
