I am having an issue when resetting the cast/heal buttons to the mouse key. After I heal, my sprite automatically fires a fireball if there is enough mana remaining.

Hi Paul, your code probably looks something like this:

if(Input.GetMouseButton(0)) {
  // cast heal
}

if(Input.GetMouseButtonUp(0)) {
  // cast fireball
}

Add an else in the middle so that if one happens, the other will not.

if(Input.GetMouseButton(0)) {
  // cast heal
} else if(Input.GetMouseButtonUp(0)) {
  // cast fireball
}

Let me know if this works.

Terence,
I tried the elif statement in my GetInputs function, but I was doing something wrong, because it was still resetting the castOrHealTimer to 0, before it checked the value, and thus casting a fireball after the heal.
//this is what I tried but couldnt get to work.

if (Input.GetButton("Cast/Heal"))
     {
         castOrHealTimer += Time.deltaTime;
         Heal();
     }
     else if (Input.GetButtonUp("Cast/Heal"))
     {
         CastSpell();
         castOrHealTimer = 0;
        
     }

//this is what finally worked for me

 if (Input.GetButtonDown("Cast/Heal"))
 {
     castOrHealTimer = 0;
 }
 if (Input.GetButton("Cast/Heal"))
 {
     castOrHealTimer += Time.deltaTime;
 }
        

I don’t know if this will cause any issues down the road, but its working better than my last fix, which was to reset the timeToCast variable in the healing function. Thank you for the help!

Hi Paul, glad you got it to work! You may want to try the following:

 if (Input.GetButton("Cast/Heal"))
 {
     castOrHealTimer += Time.deltaTime;
 }
 else if (Input.GetButtonDown("Cast/Heal"))
 {
     castOrHealTimer = 0;
 }

I’ve basically swapped the blocks and added an else. The else helps to make sure that if 1 action fires, the other does not fire, and it ensures that any given mouse click only fires 1 single action.
