Greetings!

How can I change the gravity of my entire scene programatically?

I saw that I can use the PhysicsServer to achieve this. However, when I change the gravity vector, the gravity stops working altogether.

This is the code I am using:

PhysicsServer.area_set_param(get_world().get_space(), 
    PhysicsServer.AREA_PARAM_GRAVITY_VECTOR, gravity_dir)
PhysicsServer.area_set_param(get_world().get_space(), 
    PhysicsServer.AREA_PARAM_GRAVITY, 9.8)

There is a bug open about this: [Bullet] Changing 3D gravity in BulletPhysics does not work as expected · Issue #35378 · godotengine/godot · GitHub

It works if you change the physics engine to GodotPhysics in your project settings.

Another alternative which doesn’t involve changing the physics engine is to turn off gravity, and apply its force yourself.
