How to move Character Controller from point-to-point absolutely

Questions & Answers

I’m working on a game like Subway Surf. I’m having trouble when my character needs to change lane. It won’t stop at the absolute point of the target lane. If I use the Translate to snap the character to the target position, it ignores the colliders resulting my character to go through the walls. So I used Move but can’t seem to get it right. Can someone help me with this?

EDIT: So here’s my workaround. The script for changing lane and the running movement were in a separate script.

public class ChangeLane : MonoBehaviour {

	public bool toChangeLane, toLeft, toRight;
	public bool isChangingLane;
	public Vector3 targetPosition;
	public float laneDistance;
	
	
	private CharacterController dogCtrl;
	
	void Awake()
	{
		dogCtrl = GetComponent<CharacterController>();
		targetPosition = new Vector3(transform.position.x - 2, transform.position.y, transform.position.z);
	}
	
	void Update()
	{
		if(toChangeLane)
		{
			if(toLeft)
			{
				targetPosition = new Vector3(transform.position.x - laneDistance, transform.position.y, transform.position.z);
				toLeft = false;
			}
			else if(toRight)
			{
				targetPosition = new Vector3(transform.position.x + laneDistance, transform.position.y, transform.position.z);
				toRight = false;
			}
			isChangingLane = true;
			toChangeLane = false;
		}
		
		else if(isChangingLane)
		{
			MoveToPoint();
		}
	}
	
	void MoveToPoint()
	{
		Vector3 movDiff = targetPosition - transform.position;
		if(movDiff.magnitude > .1f)
		{
			movDiff = movDiff.normalized * 15f;
			dogCtrl.Move(movDiff * Time.deltaTime);
		}
		else
		{
			transform.position = targetPosition;
			isChangingLane = false;
		}
		Debug.Log(movDiff.magnitude);
		//targetPosition = new Vector3(targetPosition.x, transform.position.y, transform.position.z);
	}
	
}

And here is the snippet from my controller that processes the running.

...
	Vector3 movement = moveDirection * runningSpeed + new Vector3 (0f, jumpingSpeed * 3f, 0f);
//moveDirection = forward
		movement *= Time.deltaTime;
		collisionFlags = dogCtrl.Move(movement);
...

It works fine except:

  1. The character falls under the ground and jump right over the target position with the code below uncommented
    targetPosition = new Vector3(targetPosition.x, transform.position.y, transform.position.z);

  2. The character swipes to the target lane a few distance backwards. It’s so noticeable since my camera follows my character

  3. And yeah, the character goes through the wall if I manipulate the transform instead of Move because my goal is to bounce back from the former lane if the character collided with an obstacle halfway its changing lane.

  4. The final position is not absolute so you can see the character not aligned in the center of the lane.

I can add more details if this is not enough and thank you for any response. :slight_smile:

Looking at just MoveToPoint() and taking the logic I posted into the comment and integrating it into your code:

   void MoveToPoint()
    {
       if (targetPosition == transform.position)
           return;

       Vector3 movDiff = targetPosition - transform.position;
       Vector3 movDir = moveDiff.normalized * 15f * Time.deltaTime;
       if(moveDir.sqrMagnitude < moveDiff.sqrMagnitude)
       {
         dogCtrl.Move(movDir);
       }
       else
       {
          dogCtrl.Move(movDiff)
       }
    }
