Getting Started

• GameMaker Manual
• GameMaker Release Notes
• GameMaker Marketplace
• Beginner GameMaker Tutorials - Tutorials from Shaun Spalding. A comprehensive introduction to basic features of the IDE. Highly recommended to check out the full playlist if you’re a complete beginner.
• Advanced GameMaker Tutorials - Tutorials from DragoniteSpam that dive into more advanced topics related to the GML language. They also have comprehensive 3D and shader introduction videos.

Recommendations

• If you already have programming experience, learn the GameMaker Language (GML) instead of the Visual (Drag and Drop) feature.
• For pixel art, Aseprite is a popular alternative to the native sprite editor. 💸
  • Aseprite’s source code can be compiled for free.
• Don’t be afraid to use other developer libraries. A lot of them are free for a reason. Just be mindful of the license.
• Updates to the IDE and runtime can break your game (like syntax changes to GML). If you are working in a group, make sure you are running on the same version of GMS and only update when given a fair warning. You can reinstall previous versions of your IDE at the GMS download page.
• Unless your game requires complex physics interactions, it’s generally advised to avoid GameMaker’s built-in physics system.
• Schedule routine backups for projects. If you are dealing with larger media files in your repo, try Git LFS.

Footnotes

• This is based on a list from GameMaker Libraries and from Gleb Tsereteli with additional links/details.
• A majority of linked resources will only work with GameMaker 2.3+ due to GML syntax changes. However, if you are working in GameMaker 1.4, most library creators would appreciate it if someone makes a backport of their project. 🙂
• If you need more general game development resources, check out Awesome Gamedev or MagicTools .
