Better way to initiate onTriggerExit2D() [solved]

Is there a better way to initiate onTriggerExit2D() than to move the unit away, then destroy it after a time delay?
I found that the time delay was needed before destroying otherwise the onTriggerExit2D() would not work.

Code (csharp):

1.  
2. void Update()
3. {
4. // If the player has zero or less health...
5. if (damageToUnit >= currentHealth) {
6.     Debug.Log ("dead");
7.     transform.position = new Vector3 (100, 100);
8.     Invoke("destroyUnit", 0.01f);
9.  
10.  }
11. }
12.  
13. void destroyUnit()
14. {
15.     Destroy (gameObject);
16. }

Thanks for reading.

 

You can always call OnTriggerXXX directly.

 

Only issue with this is that it will also kill the unit that is the victor.
After the unit is moved away both units will OnTriggerXXX.

If I test currenthealth before killing it would solve it. Which way is best?
