Game Builder

Visual editing support for MIDP 2.0 Game API including creation and editing of Sprites, TiledLayers and their arrangement into scenes. The main goal of the Game Builder module is to reduce the effort involved in creating common game components.

The following screen-shot shows the New Tiled Layer dialog which allows user to create a new tiled layer using the appropriate image resource with the correct tile size.

Once a new tiled layer is created it can be edited using the available visual editor. This allows the user to modify the contents of the tiled layer and receive instant visual feedback. The tiled layer editor also includes support for animated tiles.

Another layer type supported by the Game Builder is Sprite. In the gaming context, sprites usually serve as animated characters or objects. The screen-shot below shows the dialog used to create a new sprite.

Game Builder treats sprites as a collection of animated sequences where each sprite can be contain a number of sequences. The sprite editor allows editing and previewing of multiple animated sequences simultaneously.Below is a screen-shot showing sprite editor in action.

The scene editor is provided to organize all layers (sprites and tiled layers) together into scenes.
