No collision with invisible actors.

As_Of_Latte

Hey guys,

I have a rule that spawns a random actor every few seconds. The random actors are chosen from a set of 10 images I've made. Out of these 10 images, I have 8 visible actors and 2 "invisible" actors.

I made a separate rule for the "invisible" actors like so;

-When self.image is "Image10.png"
--Change attribute self.Color.Alpha to 0

I've set a behavior that states if random actor collides with hero, game is over.

My question is; If a random "invisible" actor is spawned, how do I turn off the collision behavior with the hero, so that the game can continue?

I assume your collision rule is set up like this:

Rule: When overlaps or collides with Hero
 -- game over. 

Add another condition:

Rule: When overlaps or collides with Hero AND when self.Color.Alpha = 1,
 -- game over. 

Since you're changing the alpha to 0 when it's an invisible image, this new rule will only fire when it collides with the hero actor who's alpha is set to 1.

Make sure the collision rule is in the 'random' actor.
Then add another condition to the rule:

When (all)  conditions are valid:  
    Actor Collides or overlaps with actor of type hero  
    Attribute self.Color.Alpha ≠ 0  
        Game Over

Edit: Beat to it by Braydon!

It can get a little confusing when people use 'actor' and 'image' interchangeably (to me at least).

If the actor is invisible and does't interact (collide) with the hero then could you not simply delete it ? Or does it have some other function ?

Thanks @Braydon_SFX‌ and @RThurman‌ that worked!!

@Socks I apologize if my wording was a little confusing. I'm still trying to get the hang of things, here in the Forums lol .
