GM-Sprite-Importer
I created a python tool that allows you to batch import images into GameMaker and automatically convert these to sprites or sprite sheets.
Features: Batch Import: Import multiple GIFs/PNGs into GameMaker. Sprite Sheets: Convert GIFs to sprite sheets automatically. Customization: Set sprite origins, sizes, and naming conventions. Auto updates .yyp project file on import. Overwrite sprite width and height (absolute size) Overwrite sprite origin -> absolute x and y or relative origin: Top Centre, Top Right, Middle Centre, Bottom Right
