AutoMapGen for GameMaker

AutoMapGen is a grid-based progression system designed for procedural path generation in GameMaker. It builds connected node maps with full control over room placement, flow, and layout style.

Key features

• Generate a floor map in two lines, and even draw the entire map in one!

map = create_auto_map(floor_length, max_options_per_step, num_of_convergence_points)
map.generate()

map.draw(horizontal, x, y, sprite, connector_nine_slice, h_spacing, v_spacing, etc.)

• Horizontal or vertical progression with adjustable spacing and layout variance

• Multiple connection algorithms: random, closest, all-paths, and weighted

• Easily add forced rooms for scripted events, bosses, or story encounters

• Automatic validation of node connectivity to ensure playability

• Generates a ds_grid of indexes with tons of helper functions to adjust to your game!

get_current_position_options() -> Array of [x,y] cells of the next possible moves based on the current position
get_index_x(xcell,ycell) -> X position of the x/y cell (for any manually animation or sprite changes)
set_position(xcell,ycell) -> Sets the new room position
get_array_of_cells_with_index -> Returns an array of all [x, y] positions in the grid that match a given room index
is_at_end_position() and is_at_start_position()
and PLENTY more!

• Ideal for roguelikes, adventure paths, dungeon routes, or quest chains

Easily integrate dynamic map layouts into your project without rigid structure or hardcoded routes.
