My friend and I are having troubles making a shooter type scrolling engine. I created a camera object for the scrolling to follow, and I tried making it a slow bouncing ball and changing it's Y position so it moves up (not both of those at the same time, though). The problem, though, is making sure the player doesn't fall off screen. If I have it simply stop when it hits the camera (which is a line, by the way) it will be quickly swallowed and put into limbo. I also tried having the character's Y position change up a bit, but every so often it still falls out. Any ideas of how to keep our hero with the camera without being devoured?

Just:
Always: set screen position to player (x,y).
Or if you have a custom camera, set that position to the player whenever nothing to do with the camera is going on.

Thanks for the help, but that's not really the problem I'm having. I must've not explained my problem well enough. Let's see...
The game we're making is going to be a shooter-type game, with automatic scrolling, meaning the camera will always be moving independently of the players. The problem I'm having is when the players hit the camera, while they usually stop, they sometimes end up being pushed through the camera, and can't come back in (since the camera would prevent them). As of now, we'v tried setting up the camera as a big box and putting up four seperate objects on all sides of the camera. Both times, we end up with the bug every once in a while.
So what I need help with is: when the camera ends up hitting the player, it should drag the player along with it, instead of passing the player up. Unfortunately, that's not always the case.

1) Make the camera an active object w/ bouncing ball movement. Have the camera's movement be a little less than the player
2) Always >> Scrollings, set window position on "camera" & have "camera" always look in direction of "player".
3) Camera is overlapping player >> Stop camera
4) (NEGATE) Camera is overlapping player >> Start camera & Set speed to [original speed (because of #5)]
5) Player is closer than 50 pixels from window's edge >> start camera & set speed to [slightly faster than player]
This makes for a good custom camera movement and also the player won't ever be out of the screen.

Weston, that last one won't work, as that last event applies to all four edges of the screen.
Instead, try this:
Create a detector object the width of the spaceship, and about a quarter of its height, and make an event which ALWAYS positions it just underneath it.
Now:
Y Position of Y (detector) is GREATER OR EQUAL than Y bottom frame: Set position of Y (Spaceship) to Y - 2 (you may need to change this value depending on your ships speed.

Thanks a ton for all your help! I think we might try that detector one first, and if that doesn't work, then we'll just use Weston's advice and stop the camera when the player collides with it. Thanks again!
