Find colliders after collision?

Question

I know it might sound a bit redundant but I need t$$anonymous$$s for my current game.

Does anyone have any idea how can I return an array of colliders that well, collide?

Basically I have an object that collides with walls, at a certain point I want to know the number of walls it collides with.

FindObjectsOfType(Collider) doesn't seem to work as it returns all the objects in the scene that have a collider. I would need somet$$anonymous$$ng like t$$anonymous$$s that could work simply for when a tag is $$anonymous$$t.

EDIT: To be more clear, I'm trying to find the colliders that I'm currently colliding with.

EDIT2: To be even more specific, I only need to count the colliders that I'm colliding with as I need an action to happen when a certain number of colliders of one tag and a number of colliders with another tag is reached.

Keep a list of colliders. When OnCollisionEnter/OnTriggerEnter occurs, add that collider to the list. When OnCollisionExit/OnTriggerExit occurs, remove that collider from the list. You now have a list of all colliders that you are currently colliding with.

Not sure if it would work for multiple objects with colliders using the same tag.

Of course it would.

OK then, thanks. I currently am unable to test this theory as I'm not at my build PC. I will come back here to mark your answer as correct if this works tomorrow ^_^.

Thanks for the quick replies!

Ok, it worked. I still have some minor glitches like making sure each collider is counted only once, but I'll try to figure that out on my own :)

In unity script you would use somet$$anonymous$$ng like t$$anonymous$$s(Some what pseudo code, i don't know uniscript syntax)

 var enemyColliders = new Array();
 
 function OnCollisionEnter(collider : enemies)
         {
             enemyColliders.push(enemies.gameObject.collider);
         }

Now you can push, pop, and s$$anonymous$$ft colliders as necessary.

I do not need to push, pop or shift the colliders. I simply need to count them.

Well after you push them aka add, then you can count them by enemyColliders.length
