FPS Crouching

Unity Engine
1

Hi, im new to scripting and i was wondering if someone could help me. I created an fps game based off of the free tutorial and i was wondering could i make my character crouch ? Any help will be appreciated ! :wink:

I donā€™t remember i that game used a player model or only the arm! If only the arm, I would make it so when the player presses a button like c, the camera and arm are moved down however much. This would simulate a crouch.

You could also shorten the ā€œcharacter Controllerā€, assuming you have oneā€¦ you can just say playerController.height = X, and playerController.center = XVector. This way, the collision boundaries of the player will be altered as well.

4

The only thing is that i dont know how to write the full code! :lol:

Something like:

function Update() {
if (Input.GetKey("c")) {
playerController.height = 0.5;
playerController.center = 0.5Vecror
}
}

THis may be wrong, however, and is certainly incomplete, but it sould give you a place to start! :smile: :smile: :smile:

Ok, I am trying to do this now, but the console says CharacterController is not static, so it cant be changed. Any idea how to do this? :?

7

Thank you SOOOOO much !!! :smile:

Actually, it doesnt work, I havent figured out how to make the CharacterController static, but I found a good alternative:

	if (Input.GetKey ("c")) {
		transform.localScale.y = 0.5;
	} else { 
		transform.localScale.y = 1;
	}

It modifys the scale of the object, and works pretty well. But IDK if it changes the childs scale too, so experiment! :smile:

Anyone have an Idea of how to do this? :?

To get variables from the character controller do:

var controller : CharacterController = GetComponent(CharacterController);
controller.height = .5;

Check the Wiki page. I know there are multiple FPS scripts there.

11

the script suggested scales the child as well as the controller. does anyone know a way of getting around this?

12

I think anyone interested in FPS should check out Dastardly Bananaā€™s weapon package. It also contains a player controller that has crouch.

How about this:

function Update () {
if () {
input GetButtonDown("c");
transform.translate((Camera)Y*0.5);
}
}

Not sure if it will work b/c iā€™m only 14 and iā€™m at school just on the forums and canā€™t do a test on the script. If it does work, though, tell me.

I have it:

function Update() {
var controller = GetComponent(CHaracterController);
if (Input.GetButton("Crouch") {
controller.height = 0.5;
} else {
controller.height = 1;
}
}

Works

function Update() {
var controller = GetComponent(CharacterController);
if (Input.GetButton(ā€œCrouchā€)) {
controller.height = 1;
}
else {
controller.height = 2;
}
}

yes that works but when you stand back up you go through the floor.

Ok I have an idea from a none scripter point of view

What if instead of using a capsule collider, or cube and changing the height of it. You have two spheres?

O

Like that, one above the other. Then when you crouch, you turn the top one off, along with the crouch animation. Stand up again and turn it back on. wouldnā€™t that work and achieve the whole crouching thing, without having the player fall through floors etc?

17

that would workā€¦ but there is a better way via script, but again that would work.
