A picture is a simple PNG images. Pictures are used as backgrounds in the game’s interface, in mission briefings, and in prologues and epilogues. They are not used in-game and are never animated; sprites are used for that.
If you’re adding new ships, you’ll probably want to add pictures for them so that you can show them in mission briefings. Also, if you’re adding levels, you may want to add pictures to show in prologues and epilogues.
If none of that applies, you don’t need to add any pictures.
Pictures are in the pictures directory and have a .png file extension.
Antares supports PNG image files.
A picture to show while the game is launching. It will be shown centered in the screen, possibly cropped, without being scaled up or down. The image should be at least 640×480.
If the plugin does not have a picture named splash, the factory scenario’s splash screen is used instead.
The image that is shown at the beginning of mission briefings. It should be sized to match the mission briefing box (533×361) and will be cropped if it’s too large.
In the factory scenario, the indicator drawn around the current star system is a 32×24 box. If you provide your own star map, you may prefer to use similarly-sized stars.
If the plugin does not have a picture named starmap, the factory scenario’s starmap is used instead.
