Obtener colisiones para múltiples objetos sin las devoluciones de llamada de colisión

I'm making a platformer (sidescroller), and right now I'm making a grenade-launcher for the player.

It spawns grenades which is a prefab, this prefab has a Circle Collider 2D which is the blast radius for the explosion.

When a grenade is spawned I run this (amongst other things);

        // Add the initial force
    rBody.AddForce(new Vector2(forceX, forceY) *300f);
    Invoke("Explode", 2.5f);

I'm having trouble figuring out how I should handle the Explode function. I would like to find all the GameObjects that are colliding with the Circle Collider 2D at that point, but I can't find a way to do it.

I would like to be able to do something like this (not real code but you understand what I'm trying to do)

void Explode () {
            collidingObjects = circleCollider.getCollisions();
            foreach(collidingObject as entity) {
                if(entity = 'player')
                elseif(entity = 'enemy')

I'm guessing that it wouldn't work so can anyone point me in the right direction?

In your grenade's script, use OnTriggerEnter or OnCollisionEnter to log collisions; basically just have a HashSet for each grenade that is updated and keeps track of what it is colliding with. Then Explode just has to iterate through this set when you call it.
