Title: Flickering issues in Map Editor
Post by: Shaham on 2006-10-26, 04:34:56 AM

Hi,
I have just downloaded ver 1.4.6 of the Scrolling Game Development Kit, and can I firstly say I think this is a great package. I have never written a game previously, and this makes it so easy!!

I am experiencing an issue however when I try and draw my maps in that I only seem to be able to scroll in the top 4 rows and get a lot of flickering as I am moving around. I find this is a little hard on the eyes. Is anyone aware of what may be causing this and how to fix the problem?

If you can oly draw in the top four rows, your map may be only tall enough to allow for four rows. For example, if the map uses 32*32 pixel tiles, a map of 128 pixels will only be four tiles tall (map size should be typed in as pixels, not number of tiles).

As for the flickering, it could just be your video card, but I've also had problems sometimes if all the layers on a map are not transparent.

That's my suggestions of things to check. I'm not sure on these, but they are possible issues.

EDIT: I just tried making a map with less than a screen's worth of pixels, and it wouldn't let me put any tiles down. I guess that wasn't the problem...

If you can't figure out the problem, post your project somewhere I can get it and I can tell you the problem.

Hi guys,
Thanks for the suggestions eric22222, and for checking to see if your theory worked for the map size. I thinking that it is prob something along the lines of an issue with my video card or settings. Is there any special requirements that I should be aware of, or a preferred res to be working in when designing games?

If this does not prove to be the prob I'll post the files in a zip format somewhere as suggested bluemonkmn.

Thanks again for your assistance.

Have you tried editing other projects?  If other projects don't have this same problem then you can eliminate the possibility of a video card problem.  If other projects behave the same way, then I probably can't help your situation because I won't be able to see the same problem in my own environment.

i don't get exsacly what the problem is, but try lowering your video car accelleration, and the mouse won't flicker as much
