GML Development Toolbox is a collection of independent scripts assisting the development process of applications using GameMaker Language. Compatible with the most recent version of LTS 2026 version of GameMaker.

Individual scripts can be used after adding them into a GameMaker project as Script Assets straight from this repository. Alternatively, GameMaker can package multiple assets into a single importable file by performing the following:

1. Clone this repository.
2. Open the project of the cloned repository in GameMaker.
3. In the Tools toolbar, open the Create Local Package menu.
4. In Package Details, fill Display name and Package ID (Filename) fields with any name, also select Add All in the resource selection. Then select OK.
5. Select where the package file should be saved on the device.
6. Open the project in GameMaker into which the package will be imported.
7. In the Tools toolbar, open the Import Local Package menu.
8. Choose the previously saved package file and open it.
9. Choose either individual scripts or Add All. Then choose Import. The scripts should now be imported and appear in the Asset Browser, unless files with the same name already existed in the project, in which case they can be replaced or skipped.
10. Confirm that each individual file was imported successfully.
