Stop Player movement when bool changes 2D

Questions & Answers
1

Well i thought a while on how to ask this question in the most simple way possible, as it could maybe help someone in the future and not just me :smiley:

Here we go:

I have a script that moves my Player as long as I press the button “D”, the trick to it is that the player moves in “Squares” (so if he stops moving he got exactly 1/2/3/4/5 … “Squares” depending on how long you hold “D”)

That looks something like this:

public Vector3 pos;
public float walkingSpeed = 2.0f;

Start(){ pos = transform.position; }

Update(){
          if (Input.GetKey (KeyCode.D) && transform.position == pos) {
							pos += Vector3.right;

           transform.position = Vector3.MoveTowards (transform.position, pos, Time.deltaTime * walkingSpeed);
 }

Now I want to know a way to make him do the exact same thing, but instead of “D” I want a boolean to handle this. [This boolean is activated when the player “collides” with a trigger, it has nothing to do with any keys]

So if the boolean changes to false, he got exactly 1/2/3/4/5 … Sqaueres depending on how long the boolean was true.

(How) Can I do this?

Thanks for any help :slight_smile:

(c# would be great but java examples are welcome as well)

Something like…

Void OnCollisionEnter()

{
if(myBool){
// code to move your player here...
}

Untested an unformatted mainly because im answering this on my phone but hopefully it will point you in the right direction.

If you want it to activate on a collision trigger, then you need to use the appropriate method for that.

Note that this is untested code, but I think should work - or at least get you in the right direction.

// The key to check
private bool myKey = true;

void Update() {

  // Add the key to the if statement
  if (myKey && (transform.position == pos)) {
    pos += Vector3.right;
    transform.position = Vector3.MoveTowards (transform.position, pos, Time.deltaTime * walkingSpeed);
  }

}

// Triggers for when colliders touch
private void OnTriggerEnter (Collider col) {

  // First, if you want, check if it's the correct collider item by name or tag
  if (col.tag == "wall") {

    // Set the key, which will stop movement in Update method
    myKey = false;

  }
	
}

// Triggers for when the colliders stop touching
private void OnTriggerExit (Collider col) {

  // First, if you want, check if it's the correct collider item by name or tag
  if (col.tag == "wall") {

    // Set the key, which will continue movement in the Update method
    myKey = true;

  }
	
}

So I am soory if my question was a little confusing…

Any way I found a solution to my problem (might be a pretty bad one but it works in my case :D)

I allready knew how to check for trigger “collision” (i asked that a while ago :D) but my specific Problem was that the action I wanted to excecute as long as the boolean is true needed to be excecutet over and over in order to work, here is my solution:

[mainScript]
public Vector3 pos;

 Start() {pos = transform.position;}

Update() {
 if (Input.GetKey (KeyCode.D) && transform.position == pos && move_index ==  0) {
			mainScript.toRight = true; //for the animation and the direction
			

			onIceMovement = true;

			ice_index = 1;

				pos += Vector3.right;

		
		//////////////////////////////////////////////////////////////////////// INDEX 1

		if (mainScript.toRight && transform.position == pos && ice_index == 1)
		{
			
			
			pos += Vector3.right;

			ice_index = 2;

		}

		
		////////////////////////////////////////////////////////////////////////////// INDEX 2

		if (mainScript.toRight && transform.position == pos && allowDirectionRight && ice_index == 2)
		{
			onIceMovement = true;
			
			mainScript.pos += Vector3.right;
			
			ice_index = 1;
			
		}
		
		

		/////////////////////////////////////// COLLISION -> INDEX 0

		if (mainScript.col_state_up && mainScript.toDown || mainScript.col_state_down && mainScript.toUp || mainScript.col_state_left && mainScript.toRight || mainScript.col_state_right&& mainScript.toLeft ) // this is basicly to stop him from moving as soon as he "collides"
		{
			ice_index = 0f;
			
		}
		
			

		////////////////////
		transform.position = Vector3.MoveTowards (transform.position, pos, Time.deltaTime * mainScript.walkingSpeed);  //this is what needed to be excecutet over and over, together with mainScript.pos += Vector3.right

 }

This is probably one of the worst answers you will ever see but I am not that good in explaining…

To summarize it:

I just made a kind of loop, because I always changed between two different if statements which would call each other in a way…

And as soon as the process should end, none of the if statement are called until it is startet aggain with the key :slight_smile:

Aggain thanks for all the support, you simply have to love the unity community, you guys are great!
