Example GDScript for Automating Tileset Import:


# Script to automate the creation of a TileSet from an image
extends EditorPlugin

func _create_tileset_from_image(image_path: String, tile_size: Vector2):
    var tileset = TileSet.new()
    var texture = load(image_path)
    tileset.create_atlas_tile(texture, tile_size)
    
    # Define collision shapes for each tile
    var tile_count = texture.get_width() / tile_size.x
    for i in range(int(tile_count)):
        var rect = Rect2(Vector2(i * tile_size.x, 0), tile_size)
        tileset.tile_set_region(i, rect)
        
        var collision_shape = RectangleShape2D.new()
        collision_shape.extents = tile_size / 2
        var collision_polygon = CollisionShape2D.new()
        collision_polygon.shape = collision_shape
        tileset.tile_add_shape(i, collision_shape)
    
    # Save the TileSet resource
    ResourceSaver.save("res://Tilesets/AutomatedTileSet.tres", tileset)
    return tileset

This script automates the creation of a TileSet from a given image by slicing the texture based on the specified tile size, adding collision shapes, and saving the TileSet resource. Developers can modify and extend this script to accommodate more complex requirements, such as handling multiple tile layers or integrating animations.

Benefits of Scripting Automation
