You still might run into performance issues associated with simple sprite_add functions which put each resource on its own texture page and requires swaps between each loaded resource.
If you never need to have a large amount of texture memory loaded at one time, then sure the memory limit won't be an issue. This brings us to.īut hey?! I can simply throw everything as an external file and never have to worry about getting close to that 2GB limit? Not so fast. If in the future GM allows the use of multiple WAD files you can swap in/out of memory, this would make this system less useful because one of the goals of this tutorial is to mimic multiple WAD files. This is due to all resources in the IDE being bundled into the same WAD file which is all put into memory. This means that even if you have an empty room in your game and no graphics loaded, you can still run out of memory simply by having a lot of graphics in the IDE. This does nothing to address the core concern that simply having resources in the IDE uses up precious system memory and chips away at that 2GB limit even if you aren't using those resources in the game. Currently texture management within the IDE is only for VRAM which is memory loaded into a dedicated graphics card. You might be wondering why is this needed? Doesn't GM already pack sprites onto texture pages efficiently to reduce memory usage and don't we have memory management with texture_flushing? Yes this is true however its still rather limited. This is because GM1.4 creates a 32bit application when you compile your game, I'm not sure if GM2.0 compiles a 32bit game. Currently in GM, that memory limit is 2GB (but you really only have ~1.7GB) meaning that the game will not run if you use more than this amount. One of the main problems we have to solve especially for the large projects is running out of memory. If anything in the spoiler is inaccurate, please inform me so I can modify it! (skip to the tutorial if you know about this) GM does a fine job on its own for smaller games and unless you desire this amount of control and extra work, you are better off using GM's built in IDE capabilities
Its useful mainly for those who have really large projects and large resolution games where memory tends to be a source of concern. This method is not necessary for everyone and every project. This provides you with the freedom to proper memory management natively without dlls or extensions which results in allowing you to create bigger games and use more texture memory at once than you otherwise would be able to. Doing so will allow you to take control over your texture pages to optimize texture memory instead of having GM do it for you.

In this tutorial I will be demonstrating and showing you how to integrate the program TexturePacker by CodeandWeb into your graphics workflow. But the techniques are applicable to other JSON data applications.

This particular example uses texture pages created with a commercial software package called TexturePacker. This is a tutorial about creating and decoding JSON data structures.
