Collisions

[cunning moth]

thread here

OnTriggerEnter is invoked if a collider on the same object is involved in a collision where at least one collider is a trigger.

It's also invoked if the object has a Rigidbody and one of its children is involved in such a collision.

But let's step back from that for a moment.

Can you explain what your game needs to do?

[wanton gulch]

Right

[cunning moth]

No technical terms.

Just describe the gameplay.

[wanton gulch]

It spawns in 2 obstacles and the player moves around them while they come towards the player and behind the player there is a wall which is supposed to destroy said obstacles

[cunning moth]

Okay, so each obstacle could be destroyed separately?

you don't need to destroy them at exactly the same moment

they just need to be destroyed when they hit the wall

[wanton gulch]

Yeah

[cunning moth]

Then just put the destroy logic on the two boxes

and have them destroy themselves

[wanton gulch]

Like attach a script to the obstacle being spawned?

[cunning moth]

Correct.

[wanton gulch]

Okay Ill try that

[cunning moth]

I'd call it Obstacle

because that's what the thing is

an obstacle

[wanton gulch]

Yeah I already called it Obstacle

How would I make it destroy itself?

Just Destroy();?

[cunning moth]

Destroy(gameObject) will destroy the game object the component is attached to.

[wanton gulch]

Alright, the objects are being destroyed now I need them to respawn more objects after they're destroyed

[cunning moth]

Your spawner could do it every few seconds

Or it could wait for both objects to be destroyed by checking if they both equal null
