Intro to TileMapLayer

Free

Meet Godot 4's TileMapLayer and the node-per-layer way of building 2D worlds.

2

Building Your First Tileset

Free

Slice a tilesheet into a TileSet resource, then paint your first room.

3

Terrain & Autotiling

Guild Hall

Set up terrain sets so walls, paths, and water connect themselves while you paint.

4

Collision Layers on Tiles

Guild Hall

Add physics collision to tiles so the player can't walk through walls.

5

Y-Sort for Top-Down Depth

Guild Hall

Use Y-sorting so the player walks behind and in front of objects the right way.

6

Layered Maps: Ground, Walls & Props

Guild Hall

Stack ground, wall, and prop layers so the scene reads clearly.

7

The GameState Autoload

Guild Hall

Build a singleton that survives scene changes and remembers the next spawn point.

8

Doors & Scene Transitions

Guild Hall

Build an Area2D door that hands off to GameState.go_to to swap rooms.

9

Spawn Points & the Overworld

Guild Hall

Read the remembered spawn and wire up the two-room overworld with room_builder.

10

Designing the World: Rooms, Doors & Level Flow

Guild Hall

Turn your tile tools into deliberate level design: lead the player, pace the challenge, and scatter decor from data.

Is This Quest For You?

Perfect for you if:

  • You can move a character and now want a world to move them through
  • You're building a top-down RPG, adventure, or dungeon crawler
  • You want level design you can actually maintain as it grows
  • You enjoy watching a world come together tile by tile

Not for you if:

  • You haven't built a 2D player controller yet
  • You only want 3D level design
  • You want a pre-made map with no building involved
  • You'd rather skip all scene and structure work
