Character Controller Slide Action Script!

[Rovalin]

I’m trying to make a script so that when I push the “S” key my character slides. So that he can slide under objects. But I have no idea where to begin. Is there a way to rotate the character controller capsule so that it is horizontal? That’s the only way I can see doing it. Thanks for reading!

Using the crouch and run script by Aldo (awesome script), I have added sliding. Set slideSpeed and slideTimerMax. When sliding, the player can look around, but not change direction.

#pragma strict

var walkSpeed: float = 7; // regular speed
var crchSpeed: float = 3; // crouching speed
var runSpeed: float = 20; // run speed

private var chMotor: CharacterMotor;
private var ch: CharacterController;
private var tr: Transform;
private var height: float; // initial height

public var slideSpeed: float = 20; // slide speed
private var isSliding : boolean = false;
private var slideForward : Vector3; // direction of slide
private var slideTimer : float = 0.0;
public var slideTimerMax : float = 2.5; // time while sliding

function Start()
{
	chMotor = GetComponent(CharacterMotor);
	tr = transform;
	ch = GetComponent(CharacterController);
	height = ch.height;
}

function Update()
{
	var h = height;
	var speed = walkSpeed;
	
	// - run and crouch -	
	if (ch.isGrounded && Input.GetKey("left shift") || Input.GetKey("right shift")) // press Shift to run
	{
		speed = runSpeed;
	}
	if (Input.GetKey("c")) // press C to crouch
	{
		h = 0.5 * height;
		speed = crchSpeed; // slow down when crouching
	}	
	
	// - slide -	
	if (Input.GetKeyDown("f") && !isSliding) // press F to slide
	{
		slideTimer = 0.0; // start timer
		isSliding = true;
		slideForward = tr.forward;
	}
	if (isSliding)
	{
		h = 0.5 * height; // height is crouch height
		speed = slideSpeed; // speed is slide speed
		chMotor.movement.velocity = slideForward * speed;
		
		slideTimer += Time.deltaTime;
		if (slideTimer > slideTimerMax)
		{
			isSliding = false;
		}
	}	
	
	// - apply movement modifiers -	
	chMotor.movement.maxForwardSpeed = speed; // set max speed
	var lastHeight = ch.height; // crouch/stand up smoothly 
	ch.height = Mathf.Lerp(ch.height, h, 5 * Time.deltaTime);
	tr.position.y += (ch.height - lastHeight) / 2; // fix vertical position
}

     }    
     
     // - slide -    
     if (Input.GetKeyDown("LeftControl") && !isSliding) //crouch to slide
     {
         slideTimer = 0.0f; // start timer
         isSliding = true;
         slideForward = tr.forward;
     }
     if (isSliding)
     {
         h = 0.5f * height; // height is crouch height
         speed = slideSpeed; // speed is slide speed
         chMotor.movement.velocity = slideForward * speed;
         
         slideTimer += Time.deltaTime;
         if (slideTimer > slideTimerMax)
         {
             isSliding = false;
         }
     }    
     
     // - apply movement modifiers -    
     chMotor.movement.maxForwardSpeed = speed; // set max speed
     float lastHeight = ch.height; // crouch/stand up smoothly 
     ch.height = Mathf.Lerp(ch.height, h, 5 * Time.deltaTime);
     tr.position.y += (ch.height - lastHeight) / 2; // fix vertical position
 }
}

I think it should be it.
