Problem with something that seems like it'd be simple

Kamazar

Alright, so I've been away from GS for a while, so that may be the problem, but it weird that I should get something so simple wrong.

Anyways, all I'm doing is having a actor that accelerates downward (so I can neglect using the gravity function) be spawned every 2 seconds. Thing is, after about ten spawns or so, it'll start spawning every second, and speeds up until the actors start overlapping. The actors are moving at a set speed and are destroyed after exiting the screen. I just don't get it.

Do you have y-wrapping on?

Kamazar

I do, but the actor's destroyed before it reappears on the screen.

Are you applying a max speed?

Kamazar

Yep, 75.

And on top of this, my "destroy self when colliding with a certain actor" rule isn't working either... strange.

if you don't have anteing scrolling, turn off y- wrapping, that might help.

I have a scrolling background that loops.

You can make your background like this:

Say it's a starfield. Actor size doesn't matter - when you place it in your scene, just stretch it so it fills the screen.

This actor will contain the following

A movement behaviour (say direction 180, speed 90 if you're doing a side scroller).

Then underneath this a single rule:
When
Attribute self.position.X < - self.Size.Width /2

Change attribute self.position.X to self.Position.X + self.Size.Width + game.Display Size.Width

Then, put the actor in your scene as described above, and add a second instance of the actor next to it of equal size.

This will allow smooth scrolling, and will mean you can get rid of the wrap.

Hope that helps
