Question by deeredman1991 · Jul 09, 2011 at 03:48 PM · variabletimedelaylockwait

How do I make it so that it wont edit a variable again for a certain ammount of time? C#

here is part of my script...it works...except by the time it kicks in it has already collided twice so instead of subtracting 10 hp it subtracts 20...t$$anonymous$$s wouldn't be a big deal except I plan to switch to a hearts system later with much lower numbers

if you want to use t$$anonymous$$s code you will need the following -hp variable -knockback variable -isstunned variable (movement controls must be in an"if(isstuned >= 0)" statment and variable must be set to 1)

Blockquote

 //On Collision
 IEnumerator OnCollisionEnter(Collision  collision)
 {
     //with bandit
     if (collision.gameObject.tag == "Bandit")
     {
         //if bandit is to the right
         if (Physics.Raycast(transform.position,Vector3.right,10))
         {
             //take controls away from the player
             isstuned -= 1;
             //knock player to the left
             rigidbody.velocity = -transform.right * knockback;
             //wait 1 second, minus 10 hp, and then print to console for debugging
             yield return new WaitForSeconds(1);
             hp -= 10;
             print("-10 hp struck by bandit from the right"); //debug
             //give controls back to the player
             isstuned += 1;
         }
         //if bandit is to the left
         if (Physics.Raycast(transform.position,Vector3.left,10))
         {
             //take controls away from the player
             isstuned -= 1;
             //knock player to the right
             rigidbody.velocity = transform.right * knockback;
             //wait 1 second, minus 10 hp, and then print to console for debugging
             yield return new WaitForSeconds(1);
             hp -= 10;
             print ("-10 hp struck by bandit from the left"); //debug
             //give controls back to the player
             isstuned += 1;
         }
             
     }

 }

Blockquote

I hope my notes are informative to those wanting to use t$$anonymous$$s ^_^...(does need a minor fix though so you might want to either wait on a fix or attempt it yourself lol)

Have a bool isDealingDamage = false. Change your if to: if(collision.gameObject.tag == "Bandit" && !isDealingDamage) On the first line of the if(){}block set isDealingDamage = true; On the last line of the if(){}block set isDealingDamage = false;

Since both if blocks inside your if block have a WaitForSeconds(1) in them, there will be a 'buffer' of one second before damage can be dealt again.

You can create a dead time during w$$anonymous$$ch further collisions are ignored:

 public float deadTime = 0.2f;
 float nextTime = 0f;
 
 //On Collision
 IEnumerator OnCollisionEnter(Collision  collision)
 {
     //with bandit
     if (Time.time>nextTime && collision.gameObject.tag == "Bandit")
     {
         nextTime = Time.time + deadTime; 
         //if bandit is to the right
         ...

Adjust the deadTime variable to avoid multiple damage for the same $$anonymous$$t.
