GMRoomLoader

Overview

GMRoomLoader is an open source GameMaker library designed to streamline room loading at runtime. It provides methods to process the data returned by room_get_info(), use it to load rooms efficiently during gameplay, and clean up created elements when needed.

GameMaker Version: 2024.2+.

Supported Platforms: Windows, Mac.

Use Cases

• Procedural Generation. Create hand-crafted level templates and place them procedurally throughout your levels.
• UI. Hate trying to make menus through code and can't wait for GameMaker's GUI Layers? Design your interfaces in the Room Editor and load them dynamically in-game!
• Enemy Placement. Set up unique enemy layouts and spawn them around the player as they traverse the map and level up. 
• Room Thumbnails. Take screenshots of your rooms to display them in, say, a level selection menu.

Features

• Pure GML library with no external tools required.
• Multiple ways to initialize room data: single or multiple, array, prefix, tags.
• Load rooms at custom coordinates and origins, like Middle Center or Bottom Right, GameMaker sprite style.
• Options to load full rooms including all layers and elements, or only instances using existing layers or depth.
  
• Element type filtering using bitwise flags.
• Layer filtering via whitelisting/blacklisting.
• Tracking loaded elements to fetch their IDs and/or clean them up later.
  
• Room screenshotting.
