Isometric Basics in Godot 4.2 (Tilemap Setup, Stacking, Half Blocks)
Table of Contents
Introduction
This tutorial will guide you through the basics of setting up an isometric tilemap in Godot 4.2. You'll learn how to configure your tilemap, manage stacking, and utilize half blocks to create a visually appealing isometric game environment. This knowledge is essential for game developers looking to implement isometric perspectives in their projects.
Step 1: Setting Up the Isometric Tilemap
-
Create a New Scene
- Open Godot and create a new scene.
- Select
Node2D
as the root node.
-
Add a TileMap Node
- Right-click the root node and select
Add Child Node
. - Choose
TileMap
from the list.
- Right-click the root node and select
-
Configure the TileMap
- In the Inspector, set the
Cell
properties - Set
Cell Size
to(64, 32)
for standard isometric tiles. - Adjust the
Mode
toIsometric
.
- In the Inspector, set the
-
Load Your TileSet
- Import your tile set by dragging the image into the FileSystem.
- Create a new
TileSet
resource and assign the image. - Add the tiles to the TileSet in the
TileMap
properties.
Step 2: Adjusting Y Sorting and Z Index
-
Understand Y Sorting
- Y sorting is crucial for ensuring that tiles and objects render correctly in an isometric view.
- Ensure that the
Y Sort
property is enabled in yourTileMap
.
-
Set Z Index for Objects
- For any 2D objects added to the scene (like players or enemies), set their
Z Index
based on their vertical position. - Higher values will render objects higher on the screen.
- For any 2D objects added to the scene (like players or enemies), set their
Step 3: Placing Cubes in the TileMap
-
Select Tiles from the TileMap
- Click on the
Paint
tool in the TileMap. - Choose the tile you want to place from your TileSet.
- Click on the
-
Positioning Tiles
- Click on the grid to place tiles.
- Use the
Select
tool to move or delete tiles as needed.
-
Utilize Half Blocks
- To create half blocks, ensure your tiles are designed to fit half the height of a standard tile.
- Place these half blocks strategically to create depth in your scene.
Step 4: Stacking Tiles
-
Understanding Stacking
- Stacking allows you to create layers of tiles for more complex structures.
- Use multiple TileMap nodes if necessary to manage different layers.
-
Creating Stacked Structures
- Add another
TileMap
for the top layer. - Make sure to adjust the
Z Index
for each layer to ensure proper rendering order.
- Add another
