Editors #2

To read Editors #1, please go here: Editors

cocos2d for iPhone supports different formats for the sprites, tiles and fonts. The following is a list of the editors supported by cocos2d:

Tiles

The popular tile editor called Tiled can be used to generate tile maps for cocos2d. With it, you can create orthogonal, isometric and hexagonal maps.

Tiled has 2 versions:

  • Native (QT) version: This version is constantly being updated. It is much easier to use, and has a nicer GUI. The only missing feature, as of today, is support for hexagonal maps.
  • Java version: It’s the old version, it supports hexagonal, isometric and orthogonal maps, but with an uglier GUI.

Tiled QT v.0.4.0 in action

For further information regarding how to use Tiled and cocos2d, please read: Programming guide: How to use tile maps

Sprites

Robert Payne updated the old Texture Atlas Creator. The new version is now called  Zwoptex, and this is the new homepage: Zwoptex homepage

New features:

  • Has more arranging options
  • canvas size adjustment
  • Minimum spacing for arranging
  • A centralized way to load frames (similar to Flash)

Recently Robert also released the source code of the editor: http://www.cocos2d-iphone.org/forum/topic/4300

The guys from GameDoctors, also created an utility called mkatlas.pl to generate a compacted texture atlas from different image files. This utility is included in  the cocos2d distribution and can be found in the /tools directory.

Fonts

cocos2d has 3 ways to render fonts:

  • CCLabel: Which renders fonts using both system and custom .TTF files (introduced in v0.1)
  • CCLabelAtlas: Which renders fixed-width fonts from an image file (introduced in v0.5)
  • CCBitmapFontAtlas: Which renders variable-width fonts from an image file (introduced in v0.8)

To create images for CCLabelAtlas and CCBitmapFontAtlas you can use the following editors:

CCLabelAtlas:

Recently, the guys from Indeeo created a new editor for an improved LabelAtlas, called ALLabelAtlas.

This editor supports some effects like shadow, and it also adds support for kerning.

Update: tilluigi told us about a Photoshop plugin to generate SpriteSheets: http://forums.tigsource.com/index.php?topic=10578.0

If you know any other editor, please, let us know! Thanks.
