The Sprite Editor allows you to preview and edit sprites in memory. This tool is critical to see all of the sprites that are imported into the game and verifying that they are displayed correctly.
The picker displays a single page of sprites. Each page contains 256 sprites. You can have up to 8 pages of sprites in memory. It is important to note that the transparent color is represented by magenta (#FF00FF). If a sprite’s data contains no pixel data, the engine ignores it and consider the sprite empty.
The sprite editor includes a pen, eraser, line, square, circle, eye dropper, and bucket tool. In addition, you can use the two flip buttons to preview what the sprite looks like when drawn to the display using either of the flip flags. These buttons do not alter the pixel data of the sprite; they simply are used to preview what these effects would have on a current sprite.
The Sprite Editor’s drawing tools will also enforce the colors per sprite limitation you set in the data.json file.
