Tilemap Sample

This is a demonstration of tilemaps, using render_target, camera movement, incremental initialization (loading bar), and an animated avatar. Use the arrow keys, WASD, or your controller to move the avatar around.

• All sprites are defined using Classes except for the debug labels and loading bar
• It uses the simple-mood tileset, 16px x 16px tiles scaled 2x to 32px
• Dynamically generates a map 200 tiles wide by 100 tiles high.
  • Chooses either a blank floor tile, or one of 4 floor textures. Dynamically applies color to the tile based on X/Y position on the map.
• Tiles are rendered onto a map render_target infrequently, using static_sprites
• The Camera uses the map render_target as a source, and pans around the map by changing source_x/source_y
• The Avatar has standing and walking animation sequences.
• Some reusable components: Assignable and Serializable

Experiment with this code!

Suggested things to try:

• Register more tiles from the tileset in SimpleMood and then modify the random_floor method to use them
• Use a different tileset, create your own Tileset subclass
• Modify this code to use a pre-generated tile map. For example, you could generate a JSON file containing x/y positions mapping to the registered sprite name for that position (e.g. {x: 0, y: 0, tile: "floor_normal"}). Then load the JSON using $gtk.parse_json_file and iterate
• With some work, you could modify the Avatar code to introduce NPCs.
• You could also try adding objects into the map. The Map tile_matrix is a 3D array, just append another sprite to the array.
• Try changing Camera::FOLLOW_SPEED and Avatar#velocity_x or the Camera easing function
