Warning

This is an extension made by a community member and it only got through a light review by the GDevelop extension team. As such, we can't guarantee it meets all the quality standards of fully reviewed extensions.

FEATURES

Fully customizable: by adjusting the liquid properties (tension, damping, spreading), you can simulate different types of liquids such as: water, jelly, lava, etc.
Can obtain the height of the surface at any point
Allows you to have full control over visual properties such as: color opacity, effects, etc.
Can create a force at any point on the surface.
Works on all platforms.
