JenScripts - GameMaker Terrain Generation

Version 3 is in development. Progress: 80%

JenScripts is a GameMaker Studio 2 library designed for rapid prototyping and development of procedurally generated levels. It contains over 60 iterative functions that can be combined with flexible parameters to create varied terrain. JenScripts supports geometric shapes, randomized distributions, and other algorithms to produce a limitless variety of patterns within a 2D grid. The grid can then be interpreted as object indices or tilemap data to convert into terrain in your room.

Want to create a lake? Try jen_ellipse and jen_near. Want to create a river? Try jen_wander_direction or jen_wander_line. Want to create a cave? Try jen_automata. Want to create a maze? Try jen_maze_prim or jen_maze_backtrack. Want to create a building? Try jen_grid_room. Want to create an island? Try jen_heightmap_sampling. Something more complicated? Combine the functions together to form terrain that fits your ideal design, using optional arguments for extra flexibility.

Features:

• Create lines, shapes, and blobs.
• Create a wandering path between two points or in a direction.
• Maze generation with Prim’s Algorithm or Backtrack Algorithm.
• Cave generation with Cellular Automata.
• Heightmap generation with Average Sampling or Gradient Scattering.
• Copy sections of your rooms to incorporate hand-crafted content.
• Tilemap support and programmatic autotiling.
