Project Workflow

^{Home | Getting Started}

Once you’ve installed 'rotorz/unity3d-tile-system' into your project you can open the tool palette using the menu Window | Rotorz Tile System. This interface is the main entrance point to this extension and provides access to various commands and other interfaces.

Setting up the user interface

With many thanks to customer feedback we have opted to separate our interface into multiple dockable windows allowing you to customize your editor environment to better meet your workflow. It is generally useful to dock the various palette windows into the main Unity interface, though this is entirely a matter of preference.

The following interfaces can be accessed via the main tool menu | Editor Windows:

1. Tool Palette - Includes tools for interacting with tile systems.

2. Scene Palette - Useful when working with multiple tile systems.

3. Brush Palette - Lists brushes and allows selection for painting.

4. Designer - Allows you to modify the active brush or tileset.

Tip - The Tool and Brush interfaces can be joined into a single palette window by modifying User Preferences.

Setting up your scene

Tiles are painted onto a special kind of object called a tile system which must be present before you can begin to paint tiles. You can add one or more tile systems into your scene which can be positioned as needed (see Creating a Tile System).

Here are two common reasons to use multiple tile systems:

• Stack multiple tile systems to create layers of tiles.

• Define multiple grid sizes (i.e. large tiles and small tiles).

Painting tiles onto a tile system

1. With your tile system selected, activate the Paint Tool.

2. Select the brush that you would like to paint with by left clicking it in palette.

3. Use left mouse button to paint tiles onto the selected tile system.

4. Drag mouse pointer whilst holding left mouse button to paint a line of tiles.

Once you have finished painting you can deactivate the selected tool by re-clicking the associated tool button, or by selecting one of the standard Unity tools.

Creating and designing new brushes

There are several kinds of brush which can be created allowing you to paint different kinds of tile. Prefabs can be added to oriented brushes allowing you to paint 3D tiles with custom behavior scripts attached. Tileset brushes can be created allowing you to paint 2D tiles; prefabs can be attached to painted tiles when desired.

An existing brush can be opened into the designer by right-clicking on it using the Brush palette and then selecting Show in Designer... from the context menu.

See Brushes for further information.

Optimizing the tile systems in your scene

Tile meshes and colliders can be merged and unwanted aspects of tile systems can be stripped from final project builds by optimizing your tile systems. The way in which each tile system is optimized can be configured using the inspector.

The Build Scene command allows you to quickly optimize all of the tile systems in the current scene which is then saved to a separate built version of scene. It is generally a good idea to avoid making changes to built version of scene since such changes will be lost if original version of scene is built again.

See Tile System Optimization for further information.
