How to destroy all enemies on screen at once

butterbean

Just wondering how to create a rule to destroy all enemies on the screen at once, such as with an item drop?

I was thinking about this recently, and while I haven't tried it, this could work.

Create an actor that covers the whole screen. You should have it always on screen, but invisible.

Have an attribute called 'smart bomb' - have it set to false.

Then if you press a button, smart bomb is true.

On all your enemies, have as a destroy behaviour 'If smart bomb is true, then destroy'.

Hope that helps - it should work...

Cheers,

Edit - or, have no actor at all and just make it so that when smart bomb is true, destroy actor!

Something like this might work...

Create a boolean game attribute called DestroyNow, and have it set to 0 (false).
In the code for your enemies (I assume they're spawned and share the same behaviors) create a rule that says When Attribute game.DestroyNow = True, Destroy.

When you have the "item drop" event, Change Attribute to set game.DestroyNow to 1 (True).

You'll need to reset the DestroyNow attribute to 0 (False) at some logical point in the game as well, perhaps after a timer expires, giving all the enemies time to see the attribute change and destroy themselves.

Hope this helps,

Heh.

Actually, thinking about what I said earlier - having an actor that fills the screen might work - if you press the button, the actor's spawned for .3 seconds or whatever, and if the enemies collide with it, they're destroyed.
