Script is Flipping Out!

Questions & Answers

Hey everyone in the script I tried making my ai ship turn while a variable is greater than zero but it never stops and spins way faster that if it was not in this while statement. Can someone take a look at how this part of the script is rotating the ship and show me how to make it rotate for a set time like I want. Please don’t just throw documentation at me I already looked at it… thats how I came up with this is all that documentation.

void Avoid()

	{
		if(dist < 20)
		{
			followTarget = false;
			StartCoroutine (turn());
		}
	}

	IEnumerator turn()
    {
    	if(followTarget == false)
		{
			//wait the cooldown time in a loop
			float turningTime = 5f;
			while (turningTime > 0)
			{
				transform.Rotate(0, turnSpeed * Time.deltaTime, 0 * Time.deltaTime, Space.World); //and then turn the plane
				//decrement turningTime
				turningTime -= Time.deltaTime;
				//let unity free until next frame
				yield return null;
			}
		}
    }

//set the variable

float turningTime;

make the Avoid like this

void Avoid(){
    if((dist < 20)&&(followTarget)){
       followTarget = false;
       turningTime = 5f;
    }
}

and finally put this in Update

void Update(){
		
		turningTime -= Time.deltaTime;
		
		if((!followTarget)&&(turningTime>0f)){
			transform.Rotate(0, turnSpeed * Time.deltaTime, 0 * Time.deltaTime, Space.World);
		}
		
	}

Are you calling Avoid() from your Update() loop by any chance? If so, it’s probably calling turn() in every frame in which dist is less than 20, and you’ve stacked multiple coroutines to rotate the object, each of which last for 5 seconds.

Try adding a Boolean variable to indicate whether turn() is already running (set it to true/false at each end of the coroutine), and only call it from Avoid() if not already running.
