particle stars

(generated with an especially-made Godot project)


#ArtPicture made in Godot v4.2.stable.official [46dc27791] for Art Weeklies. themes used:

  • ⭕ Scene: Night View

  • ❌ Fanart: Games based around Space (No Man's Sky, Starfield, Outer Wilds...)

  • ❌ Random: Explorer

the picture is from a Desktop app that uses Godot's particle system (the CPUParticles2D variant) to generate stars.

the trick is that all particle movement is disabled and the speed_scale is set to 0, so the particles don't move and disappear.

the app is licensed under MIT License. you only need to save these 2 text files in a new folder (recommended name particle-stars) to get the Godot project :
