Effective way to change var after buttondown
Hi, I have an object that constantly rotates around its Y axis. I want to change the direction of the rotation each time I press (either tap/hold) a button. The direction of the rotation is fixed by an INT variable that is changed from 1 to 0 (1=right, 0=left).
I've written a function that is called inside FixedUpdate, and it basically works, but sometimes it "misses" and failed to change the variable.
private int RotationDirection;
void Start () {
RotationDirection=1;
}
void FixedUpdate () {
switchRotation();
}
void switchRotation(){
if(RotationDirection==0 && Input.GetButtonDown("Fire1")){
RotationDirection=1;
}
else{
if(RotationDirection==1 && Input.GetButtonDown("Fire1")){
RotationDirection=0;
}
}
}
Is there a way to change that variable in a "Full Proof" way?

Hello, first off, I wouldn't put this code in fixedupdate. That is for very fast, physics oriented calculations. Instead, I would write the code like:
void Update()
{
if(Input.GetButtonDown("Fire1")){
if(RotationDirection == 0)
RotationDirection = 1;
else
RotationDirection = 0;
}
}
This will work. The IF statement is also simplified to avoid your "skipping" issue
