Getting Input.GetAxis to Execute Once

Questions & Answers
1

I wanna have Input.GetAxis to act like regular button (e.g. Input.GetButtonUp ).

As I’m using the GetAxis, everytime I shift the stick to one direction, the command inside the function is executed more than once, only need it to be executed once. Here’s my code. Anyway I can remedy this?

if ( Input.GetAxis("RightStickX") == 1 )
{
    SwitchTarget();
}

I’ve found a way moments later after I posted this, here’s what I did to resolve my own problem. GetAxisRaw returns only 0 or 1/-1, it just doesn’t have the GetButtonUp function, so had to be resolved with a condition check, in this case using boolean axisInUse. Thanks for taking the time to help, appreciate it.

private bool axisInUse = false;

		if (Input.GetAxisRaw("RightStickX") == 1)
		{
			if (axisInUse == false)
			{
				axisInUse = true;
				SwitchTarget();
				Debug.Log ("+1 Switch!");
			}
		}
		else if (Input.GetAxisRaw("RightStickX") == -1)
		{
			if (axisInUse == false)
			{
				axisInUse = true;
				SwitchTarget();
				Debug.Log ("-1 Switch!");
			}
		}

What you could do is use a Coroutine to allow a cooldown of X seconds before you switch to the next target. For example:

public bool canSwitchTarget = true;
public float coolDownUntilNextSwitch = 1.0f;

public void Controls()
{
    ...
    if(Input.GetAxis("RightStickX") == 1 )
    {
        StartCoroutine(SwitchTargetRoutine(coolDownUntilNextSwitch));
    }
}

IEnumerator SwitchTargetRoutine(float duration)
{
    if(canSwitchTarget)
    {
         canSwitchTarget = false;
         SwitchTarget();
         yield return new WaitForSeconds( duration );
         canSwitchTarget = true;
    }
    else
    {
         yield return new WaitForSeconds( 0f );
    }
}

public void SwitchTarget()
{
    // your functions logic to switch targets
}

Hope this helps. Haven’t actually tested the code…

int state;
int cooldown;
if (state == 0) {
var inp_vert = Input.GetAxis (“Vertical”);

			if (inp_vert != 0) {
				cooldown = 60;
				state = 1;
			}
		}
		if (state == 1) { 
			//Do what you need to do
			state = 3;
		}
		if (state == 2) {
			cooldown--;
			if (cooldown < 1)
				state = 0;
		}
