Question Animation loop & trigger collision

Hi all,
Here's my problem : I have a very simple animation looping over 3 frames. It's a sword swing animation.
And I want the enemy health to deplete every time the it's hit at the 2nd frame.

I've set a gameObject "attack" being the child of my "knight" asset and added a trigger collider, like so

the enemy has a non trigger circle collider. I added a OnHitEnable collider on the 3rd frame

and here's my code for the trigger

Code (CSharp):

1. private void OnTriggerEnter2D(Collider2D collider)
2. {
3.  
4.  
5.     if (collider.CompareTag("Enemy"))
6.     {
7.  
8.         stats = collider.GetComponent<Stat>();
9.  
10.         int health = stats.GetHealth();
11.  
12.         if (health <= 0)
13.         {
14.             //etc...

So far the code has been triggering only once even though the animation loops correctly. But I'd like to enter the trigger more than once, to deplete heatlh by bits.

1-Am I doing correctly so far ?
2- Should I add an intermediate state after and and/or before so the animation collider resets and I can reenter the trigger?

 

You probably want to use Animation events to enable/disable the collider at the moments of "impact". OnTriggerEnter will trigger once per collider Entrance. If you enable and disable it properly, it will re-trigger once per enable.

Currently, your collider is probably always in contact with the enemy or object so it is triggering just once.

 

Thanks for your answer ^^.
That's my diagnosis too. The enemy is has entered the collder and that's it...

But I already added OnHitEnableCollider on the 3rd frame, isn't that what it's supposed to do ?

 

When are you disabling it? You need to enable it on a down-swing or point of impact, then disable it. Then enable it again for the 2nd and 3rd attack, with the respective disables as well. So if you have 1 animation that has 3 sword swings, you need 3 enables and 3 disable animation events

 

not even sure I'm disabling or enabling it. I'll check that way. Thanks a lot.
