Crouching Script -WORKING-

Unity Engine
1

I made a crouching script using Java. I just thought someone might want it :slight_smile:

//Is Crouching?
private var crouch = false;
//Create Position variables for Player
var xpos = 0;
var ypos = 0;
var zpos = 0;
//Start
function Update ()
{
	//If Press "C"
	if(Input.GetKeyDown("c"))
	{
		//If player is not crouching then..
		if (crouch == false)
		{
			//Scaling Player down
			transform.localScale += Vector3(0,-1,0);
			//Player is crouching
			crouch = true;
		}
		//If player is crouching
		else
			{
				//Read current Position of player
				xpos = (transform.position.x);
				ypos = (transform.position.y + 0.49);
				zpos = (transform.position.z);
				//Move player to specified position
				transform.position = Vector3(xpos, ypos, zpos);
				//Scale player back to normal size
				transform.localScale += Vector3(0,1,0);
				//Set to not crouching
				crouch = false;
			}
	}
}

For transform.localScale you can just use ( transform.localScale.y = 0.5; ) instead of += Vector3(0, -1, 0); .
The real trick with crouch code is not having your child items (weapons) crouch too/scale down. If anyone knows how to do that it would make a sweet addition. You don’t need the xpos or the zpos also. To prevent you from falling through the terrain.

I agree it would be a problem if the weapons scaled too xD

The only real issue I see is that if you have an object with a rigid body above you when you get back up, the object launches in the air xD Is there a way to not allow you to get back up if there is an object right above you?

nvm I figured it out ^^
I added a raycast as tall as my player object.

//Is Crouching?
private var crouch = false;
//Create Position variables for Player
var xpos = 0;
var ypos = 0;
var zpos = 0;
//Height of Player = Raycast Height
var heightchar = 0.0;
//Start

function Update ()
{
	//If Press "C"
	if(Input.GetKeyDown("c"))
	{
		//If player is not crouching then..
		if (crouch == false)
		{
			//Scaling Player down
			transform.localScale += Vector3(0,-1,0);
			//Player is crouching
			crouch = true;
		}
		//If player is crouching
		else
			{
			//If Raycast off player pointing upwards with height of player IS hitting something
			if (Physics.Raycast (transform.position, Vector3.up, heightchar)) {
			//Read current Position of player
			xpos = (transform.position.x);
			ypos = (transform.position.y + 0.1);
			zpos = (transform.position.z);
			//Move player to specified position
			transform.position = Vector3(xpos, ypos, zpos);
			xpos = (transform.position.x);
			ypos = (transform.position.y - 0.1);
			zpos = (transform.position.z);
			transform.position = Vector3(xpos, ypos, zpos);
			}
			//If not..
			else
			{
				//Read current Position of player
				xpos = (transform.position.x);
				ypos = (transform.position.y + 0.49);
				zpos = (transform.position.z);
				//Move player to specified position
				transform.position = Vector3(xpos, ypos, zpos);
				//Scale player back to normal size
				transform.localScale += Vector3(0,1,0);
				//Set to not crouching
				crouch = false;
			}
			}
	}
}

Just heightchar to the desired height and your character player wont get back up from crouching if something is above him.
