Sprite Sheet

Animations

Sprite List

The sprite list shows all the sprites that have been added to the sprite sheet.  You can select individual sprites here, or multiple sprites using the shift and control keys.  To add a new sprite, click the ‘Add a new sprite’ button and to remove the selected sprites, click the ‘remove selected sprites button’

Sprite Sheet Preview

This area shows you a preview of how the resulting sprite sheet will look.  It is updated in real-time as you make changes to the options and add/remove sprites to the project.  As you change the layout options, you can see at a glance how it affects the layout, which will help you to find the best options for your needs.  The size of the sprite sheet is automatically adjusted as sprites are added/removed so that you don’t have to worry about what size to use.  If you do want to manually control the size of the sprite sheet, you can turn automatic sizing off in the options....

Sprite Details

This area shows the details of the currently selected sprite (or the first one if multiple sprites are selected).  Here you can change the name of the sprite to something meaningful if desired (the image filename is used as the default) as well as whether the sprite is trimmed (excess whitespace removed).

Options

The options pane lets you control, in real-time, how the sprite sheet is layed out.  Commonly used options that are required by many engines are supported, such as OpenGL textures (power of two sizes) and square textures.  You can also control the format of the exported sprite sheet.  In the basic edition of Predator you can only use the tile layout, which is still useful for many engines.  In the professional edition you have access to the optimised layout engine which gives you many more options to maximise the number of sprites that can be fitted onto the sprite sheet.
