Right, well I'm making a game and I simply want to place three buttons on the screen. Each button simply has two frames; pushed down, and not pushed down. All three were made based on just one template and they were made in Paint. Yet, when I load and display them in the code bellow, two come out at double the size while one remains correct. Has anyone any idea why this is happening? Here is the code I think could possibly be relivent to this problem:



This is the majority of the code so far. I have only left out a few irrelivent variables which are not yet used at all. It is sprites 4 and 5 which are becoming double sized; 3 is working fine. I can assure you that they are all 808 X 51 pixels with both frames together.

Any help would be greatfully recieved. Just ask if there is any relivent information I have left out. Thanks in advance for your help.

You shouldn't be so specific when loading images. Other computers running the program won't be able to find the images to load, since not everyone is named Laurie. Load media using the .exe as a base. If your .exe is in "C: Documents Game thegame.exe", then keep your media in subfolders in the Game folder. So instead of "C: Documents Games Pics Cycling RaceOpponent.bmp", use "Pics Cycling RaceOpponent.bmp". When distributing the game, keep the folders in the same place in relation to the .exe.

Also, there's no point in creating animated sprites with one frame. Just use load image in that case.

I can't tell why your images aren't sizing correctly from the snippet you posted. Try adding ,1 after loading image 6. This flag will set the image into a high quality mode or something like that, and that can have effects on how other images are displayed. Maybe, I'm not sure exactly how it works, but I don't load an image without it.

Thanks for the tips people. I have moved the pics into a subfolder of the exe. However my main problem still remains... Why do they double in size. After correcting a couple of errors, I can see the problem more clearly now. The strange thing is that they are double the width they should be but not double the height.

Any help on this or anything else is much apreciated.

I never thought of that, thanks WindowsKiller! But doesn't that mean you can't set that image's texture flag (looked up what it was )? You couldn't use sprites with alpha channel transparencies, or could you?

Lucas, try deleting and rewriting the portions of the code pertaining to these buttons... make a backup dba first, though. It's not a guaranteed fix, but by rewriting the code you may find a small error causing the problem. I remember having a horizontal stretching problem once when using animated sprites, but I can't recall how I fixed it :\

Thanks once again for your help.

pcRaider; thanks for the code but you know, it still doubles the width of the first two versions of a. The third one works fine, just like when it has my credits sprite in it. Does this not happen for you?

If not, I may try uploading my version of the game with sprites to see if anyone else has the same prob as me. Thanks once again.

Your DBP is mysterious.
I need your information.
-
1) Is it Windows Xp or Vista?
2) What is a version of DBP?
Are you latest Version?

You can attach a .exe file.

I think I've just found the problem, or more acuratly, a solution to it. When I set the frame before offsetting the sprite, it work. I have no idea why that should be though.

I am working on XP and I got my DBP fairly recently so I can't imagin I'm very far behind in unpgrades. Thanks for all your help.
