Out of Memory problem.

Gimbabwe · October 23, 2015 at 12:55 AM

Hello CTF forums

I've been having this problem for about 3 years now and I still haven't come any closer to a fix or answer as to why it happens or what is causing it. When building a game as a stand alone application after a few seconds it will display an "Out of Memory" error message and cancel. This same error also pops up after switching between frames of the game eventually causing to slow when loading it to where the frame will simply not load some assets to eventually not being able to do anything as the error keeps popping up.

If anyone has any help or information on this matter it would be greatly appreciated.

The most common reason for this is that the assets within your game are simply too large. What sort of resolutions of image are you using, how big is the mfa file on the disk before you try to build it?

The game file is about 181 MB large. There are quite a few large images in the game as drawn backdrops.

One thing you should do with larger graphics is to make sure they are optimized by the power of 2

Please login to see this link.

If they are not optimized this way they can use quite a bit more memory than they need to

Also, what format are your sound files?

OGG is a great format due to it's small file size and because it's a free and open standard

This is good advice, however 181mb is not particularly large as it goes. I've seen people with mfas of multiple gigabytes before now. What sort of size are these large images for the backdrops?

On the larger end of the image sizes is a backdrop approx. 12999 x 1379

Most level backgrounds are made in such a way that 3 or 2 of these backgrounds are arranged in such a way as to have a parralaxing effect. All on different layers

OK so that is a pretty large image to be using. I imagine that is what is causing the problem. Try removing some of the larger images and build. If the memory error goes away you'll know where the problem lies.

it is like you use an image of 16384 x 2048 px ! so try to change the dimension to 8192x1024 and use a Xscale/Yscale in the start of frame. you will divide by 4 the size of this image. In this example, xscale=1.587 and yscale=1.347.

At what point does a backdrop become "Too large" to realistically load consistently? Is there a specific size?

Gimbabwe · October 30, 2015 at 3:54 AM

Alas, deleting nearly all background images does not seem to have helped. Perhaps its something else?

DaveC · October 30, 2015 at 4:33 AM

what is your target device and what are you using to develop on? your 1 texture size of 16384 x 2048 would require roughly ~100mb of memory, if you had a lot of these images that would cause a problem pretty quickly, especially if you have animated backgrounds or something..

Probably best to let someone take a look at your file, or just do a process of elimination to find the culprit.

edit. one more thing, deleting instances of the background might not have an impact, you might have to completely remove the texture from memory.

Update, while originally I couldn't even run the game anymore without that message popping up, it seems to have changed as now I can play it. I have yet to try building it. I was going to try to make it for desktops only as a start, to answer your question.

Gimbabwe · October 30, 2015 at 7:05 PM

I can actually build the game now. The only other issue I can think of now is the problem of using the popup message object to make dialogue show up but a lot of times it doesn't show up at all. Or the first few messages will show up but the rest will not, soft locking the game. When running the game in standard mode, the popup messages would usually show, but now only the first few messages appear and the rest don't ever show up. When running in Direct 3D9, the game stops for a second but the message will not show. There's also the problem of the menu bar not showing in this mode, which is also used as a crucial gameplay aspect.

Is there at least a way to get the menu to popup when in Direct3D9 mode?

DaveC · November 4, 2015 at 6:31 AM

I don't think anyone knows what you're talking about.. can you post a simple example file demonstrating the problem you're having?

Gimbabwe · November 10, 2015 at 6:56 AM

If you press F8 during gameplay the menu for the application should from the top however when playing in Direct3D9 the menu will not show when pressing F8. Is there a way to make it show when playing in this mode?
