Just add gravity

Question

I created an editor plugin that opens a 3D scene in a separate Window. The scene displays and functions normally except there is no gravity. Gravity works fine if I open the same scene by running the project.

I’m guessing that opening the scene as part of the editor plugin does not establish a proper environment. What am I missing?

I think your problem is similar to this

Activating a RigidBody in editor

Attention Topic was automatically imported from the old Question2Answer platform. Asked By andersmmg I want to start simulation of a RigidBody while still in the editor, mostly for level design. Rather than placing it manually and having it maybe jump when the level is loaded, it would be great to be able to place it and have it fall into place using physics simulation. Is this possible? I don’t see any options in the editor for enabling…

I have @tool in all the involved scripts. Everything works as expected, including move_and_slide(), Only get_gravity() always returns Vector3.ZERO.

I solved the problem by checking for zero gravity and forcing a hardcoded gravity.

In _physics_process():

func _physics_process(delta: float) -> void:
	var gforce:Vector3;
	
	if get_gravity() == Vector3.ZERO:
		gforce = Vector3(0.0, -9.8, 0.0);
	else:
		gforce = get_gravity();

You could try explicitly setting the gravity in your plugin’s initialization code. Make sure that the physics engine is properly set up when you load the scene in the separate window.
