Strange Graphics Error

| Hi everyone, When I try to create an exe file, or run my program without debug enabled, I get an error saying "Unable to set Graphics Mode". Why is this, and what can I do to fix it? Thanks for helping. |
| ||
| You can get this error ocassionally, usually when you have another graphics app running. If closing the other apps doesn't fix it, reboot and it should be OK. |
| ||
| Hmm... rebooting didn't work. Anything else that might? |
| ||
| Are you setting a 2D or 3D graphics mode? Infact, can we see some code? |
| ||
| ok... it's a very simple program. AppTitle "Romules and Remus" music = PlayMusic ("Eagleland__Onett.mid") Graphics 611,349 SetBuffer BackBuffer () .start intro = LoadImage ("tiberintro.bmp") DrawImage intro, 0,0 Flip begin$ = Input ("") If begin$ = "" Then Goto slide1 .slide1 StopChannel music music2 = PlayMusic ("sadness.mid") Cls Graphics 827,682 slde1 = LoadImage ("tiberbank.bmp") DrawImage slde1, 0,0 Flip WaitKey Goto slide2 .slide2 StopChannel music2 music4 = PlayMusic ("notlike.mid") Cls Graphics 518,456 disagree = LoadImage ("disagree.bmp") DrawImage disagree, 0,0 Flip WaitKey Goto slide3 .slide3 StopChannel music2 music3 = PlayMusic ("linktheme.mid") Cls Graphics 708,419 mount = LoadImage ("decide.bmp") DrawImage mount, 0,0 Flip WaitKey Goto slide4 .slide4 StopChannel music3 music4 = PlayMusic ("fighting.mid") Cls Graphics 773,576 fight = LoadImage ("twinfight.bmp") DrawImage fight, 0,0 Flip WaitKey Goto endshow .endshow StopChannel music4 endmusic = PlayMusic ("endmusic.mid.") Cls Graphics 522,403 endimg = LoadImage ("ending.bmp") DrawImage endimg, 0,0 Flip WaitKey End |

| OK, that ran in debug because running in debug uses a window that can be set to strange sizes like 522x403, however, without debug on that will run in fullscreen and modes like 522x403 aren't supported! You need to set a flag in the Graphics command to specify windowed mode (see docs). |
| ||
| Yeah, always specify the windowed mode explicitly, something like Graphics 640,480,32,2 I always thought it was odd that it varies between fullscreen/windowed based on whether or not you are debugging, but if you set the flag explicitly then it won't matter. You need to set a flag in the Graphics command to specify windowed mode (see docs). That or use standard resolutions. Like 640x480, 800x600, 1024x768, etc. |
| ||
| Thanks everyone! This should solve my problem... |
| ||
| Any reason why you need to alter the screen resolution for each image? |
| ||
| Oh yeah, I didn't even think of that. wtf? |
| ||
| Any reason why you need to alter the screen resolution for each image? I figured he just wants to do a slide show where each image is nicely framed in a window. It's a bit unorthodox but there's no real reason not to do it this way. |
| ||
| It's a bit unorthodox but there's no real reason not to do it this way. As long as you do not try it in fullscreen mode. |
| ||
| As long as you do not try it in fullscreen mode. We've already established that. ;) |
| ||
| Umm to add in, I believe there is a command of GFXModeExist or sumtin to check to see if the system supports it. And I usualy set all my parameters when calling graphics. IE. "Graphics3D 1024,768,32,1" |
| ||
| @big10p We've already established that. ;) And why did you write this nonsense then? ;-) It's a bit unorthodox but there's no real reason not to do it this way. There is one ... it doesn't work in Fullscreen mode as I say again and it makes no sense in Windowed mode because in this case the pictures are not fullscreen... So what ? :-P |
| ||
| to quote big10p... OK, that ran in debug because running in debug uses a window that can be set to strange sizes like 522x403, however, without debug on that will run in fullscreen and modes like 522x403 aren't supported! |

| RaGR: I suggest you read through the whole thread again - you seem to have missed the point. To sum up: he wants to use windowed mode, not fullscreen - that's why he's changing modes for each image. As Ross C points out, I've already said it won't work in fullscreen mode. ;) |
