1. Basic Features for Map Generation

In RPG in a Box, the following functions are commonly used for procedural map generation:

place_tile: Places tiles dynamically on the map.
place_object: Adds objects like enemies, chests, or decorations at specific locations.
random: Generates random numbers or selects values from an array.
set_region_tiles: Modifies a defined area on the map.

2. Example Script for Map Generation

Tile Placement:
for x in range(0, map_width):
for y in range(0, map_height):
var tile_type = random(["grass", "sand", "water"]);
place_tile("layer_1", tile_type, x, y);

Object Placement:
for i in range(0, 5): # Place 5 objects
var x = random(0, map_width);
var y = random(0, map_height);
place_object("tree", x, y);

3. Advanced Map Generation

Using Room Templates:
Prepare predefined map sections, like rooms or corridors.
Place them using set_region_tiles:
set_region_tiles("layer_1", "room_template", 10, 10, 5, 5);
"Checkerboard" Tile Placement:
for x in range(0, map_width, 2):
for y in range(0, map_height, 2):
place_tile("layer_1", "stone", x, y);

4. Adding a Widget for Map Control

You can use Widget Editor to create a button for triggering map generation:

Create a widget with a button labeled "Generate Map."
Link the button to your script:
call_function("generate_map");

5. Debugging and Testing

Use log to print messages for debugging:
log("Tile placed at: " + x + ", " + y);
Experiment with multiple generation styles (caves, fields, dungeons) and integrate them into one script.
