How to add Delay before finding GameObject - unity3d

Question

I am trying to make a game in where you can stab an enemy, the enemy struggles for about a second and drops dead. (ragdoll);
i think its best to just show my script and you know what I mean:
In an on trigger enter script:
if(other.tag == "enemy"){
other.transform.parent.gameObject.name = ("enemy" + currentEnemy);
print(other.name);
gameObject.Find("enemy" + currentEnemy).GetComponent("RagdollOrNot").MakeKinematicFalse();
BloodParticle.emit = true;
Stabbed = true;
Character.GetComponent("MouseLook").enabled = false;
Character.GetComponent("CharacterMotor").enabled = false;
}
and in the update function:
if(Stabbed == true){
StopBleeding ++;
}
if(StopBleeding > 50){
Stabbed = false;
StopBleeding = 0;
currentEnemy ++;
Character.GetComponent("MouseLook").enabled = true;
Character.GetComponent("CharacterMotor").enabled = true;
BloodParticle.emit = false;
}
Now when my knife enters the collision of the enemy the enemy imediatly drops to the floor.
I tried putting the:
gameObject.Find("enemy" + currentEnemy).GetComponent("RagdollOrNot").MakeKinematicFalse();
in the update function in if(StopBleeding > 50).
if I do that I get an error of Null reverance exception becaus the script cand find the enemy. While it can I its in the trigger enter.
Basicly my question is: Is there any way to fix this error to give it a 50 frame delay (all the rest in StopBleeding works)?
Or is there any way I can put a simple delay in before the Ragdoll gets activated?
Thanks in advance

Answer 1

You can use StartCoroutine("DelayDeath"); where DelayDeath is the name of a method. See below.
if(other.tag == "enemy"){
other.transform.parent.gameObject.name = ("enemy" + currentEnemy);
print(other.name);
StartCoroutine("DelayDeath");
BloodParticle.emit = true;
Stabbed = true;
Character.GetComponent("MouseLook").enabled = false;
Character.GetComponent("CharacterMotor").enabled = false;
}
private IEnumerator DelayDeath()
{
//this will return...and one second later re-enter and finish the method
yield return new WaitForSeconds(1.0f);
gameObject.Find("enemy" + currentEnemy).GetComponent("RagdollOrNot").MakeKinematicFalse();
}

Since you're asking specifically about Unity JS and not C#, you'll use the yield keyword.
print("foo");
yield WaitForSeconds (5.0); // waits for 5 seconds before executing the rest of the code
print("bar");

Answer 3

On stabbing you could look up the enemy object but save it away in a variable instead of issuing the enemies dead. After the bleeding finishes you don't have to look up the enemy and can trigger the death on the saved one.
Another hint: Don't count frames as frames might be of different length. Add up time from Time.deltaTime until you reach let's say 2 seconds and then trigger the death.
Hope that helps.
