Description

Procedural 2D Clouds Extension

Generate and control dynamic, procedural 2D cloud layers in your GDevelop 3D scenes.

Features:

  • Procedural Generation: Unique, non-repeating cloud patterns using advanced noise.
  • Customizable:
    • Visuals: Adjust color, transparency, density, sharpness, and edge softness.
    • Animation: Set independent horizontal and vertical movement speeds.
    • Pattern: Control unique cloud shapes with seed, tiling, and FBM (Octaves, Persistence, Lacunarity) parameters.
  • Multiple Layers: Create distinct cloud layers with unique IDs and properties.

Limitations:

  • Clouds doesn’t cast shadows.
  • Suitable for the game that camera stays at ground level.

Why I didn't use custom object and let the player set the dimension in the action

Object dimension of the custom object in Gdevelop scene doesn't matches to the runtime scene. No matter what I tried it didn't worked. There was a huge dimension difference between object dimension (threejs plane geometry) and how it was shown in the game preview.

How to use the extension

There are two actions in the extension.

Create Cloud Plane, creates a plane with all the transform, dimension and parameter values that control the FBM noise and animations.

Destroy Cloud Plane, removes the created plane when it is not needed anymore to release the resources it takes.
