Scrolling at the Start of Frame

[RHIT_Guy]

I have been working on an advanced scrolling engine for 640x480 based game which works pretty good. The only thing is that at the beginning of a frame, if the object which the camera is focused on is out side the x=640 y=480 zone of the frame which is 2000x480, I get this after image of the x=640 y=480 area. The image is only there for a split second and dosn't effect the game play. I just wish I could figure out how to get rid of this problem. I know this isn't the best explanation, if someone needs my file I'll send it via e-mail . Thanks in advance

The way I fixed it was by placing a black alpha channel object/active object that loads before the frame transition in the 320x240 area (or 640x480 in your case) and setting the frame fade-in to 0.01. Afterwards, I just make the alpha go transparent in a small lapse of time, which makes a nice moving fade-in transition.

Another way you could do it, though I don't know if it works, is by making the screen center its position relative to an extension instead of an active object. Then, you can turn on the "load before frame transition" checkbox and set the frame fade in to 0'00. That's basically the same principle, anyway.

[edit] This seems to be a layer problem, actually. I'm not sure about the details, but try it with only 1 layer and it doesn't happen.

I'll try the alpha technique. I really hope it's not because of layers and if so, there is a simple fix. Most of my frames use a lot of layers.
