What's the best way to shoot an object?

[Ravenius]

In my topdown - like shooter game, I've used the "create object at player" condition to make the bullet and then set it as bouncing ball to face the mouse. Well, it works fine if you don't move. When I start shooting a bit more and the screen is scrolling, I see bullets flying everywhere in random directions. I do delete the bullets every time they go out of the frame, but that doesn't really help. My framesize is 2000 x 2000 if that helps at all. Using 247.

why no delete them when there at the windows edge?

"Out of the frame" isn't the same thing as "out of the window", though.

You mentioned scrolling, so I'm guessing the size of your frame is bigger than the size of your game window. Therefore, though the bullets may be going past the edge of the window, they're still within the frame.

Remember that the "frame" is the entire play area; the window's just what you can currently see on the screen.

Hmm, you may be right about that. I changed the destroy event to happen when the bullet is 1 pixel to the window's edge and it works fine now. Must've been that it set the objects to be still (not active) when too far from the windowand then they reactivated when I went close and started to fly again. Such as simple solution again, thanks!

Ha, funny I had this problem too in one of my first games. You can also just set the bullet's properties to remain active even off frame. However the second problem with leaving the bullet active is, whatever it hits (off screen) reacts when you finnaly see them, most often just dying where they stand. Therefore, the enemies must be active off screen as well, and normally that isn't what you'd want.

Your solution definately works better than changing the properties of the objects, I had to reprogram most of mine because I didn't have much experience in MMF2.
