Question by Parzivell · Jul 05, 2014 at 01:22 PM · inputtriggertimeint

Hold down button for in trigger

Hello everyone. I am trying to make a part in my game where you would walk up to a water hole and hold down "e" for 5 seconds and the water integer increases. I have been using a trigger to do this and it has worked so far, but i need to know how to hold the button down for 5 seconds, then it increases the variable. Here is my code (fairly simple)

Thank-You

     var playerObj : GameObject;    
 
         
 
 
     
     
     function OnTriggerStay (other : Collider) 
     {
     
         
         if(Input.GetKeyDown("e"))
         {
         playerObj.GetComponent(GUISurvival_Icons).currentThirst += 10;
         }
         
         
     }

For the time, you can use delta time. Each intiger of 1 is 1 second in length. You can set an alarm when the trigger is entered and reset it to five when it's left. Here's how I use mine.

 public var Alarm1 : float = -0.1;
 
 function Update () {
         // Alarm1 activation. While the alarm is greater than zero, raise the water.
              if(Alarm1 > 0){
               Alarm1 -= Time.deltaTime;
         }
         // If alarm1 runs out, personally, I prefer set it to -0.1 to keep it below zero. It should've be 5 seconds by here.
         if(Alarm1 < 0){
                         Alarm1 = -0.1;
                         //Water code.
                 }
 }

If the button is released, just reset the alarm to 5.

I hope this helps out and good luck with your project!
