Hi
I want the player to enter an area which triggers an inverted gravity of the whole world (3d).
I read multiple other threads about similar issues, but was not able to find a solution.
If I go to project settings > physics > 3d
I can find the default gravity and the default gravity vector.
I would like to change the default gravity vector during runtime.
If I hover above the setting It even gives me some code:
Oh I realized, actually both following ways work: ProjectSettings.set_setting("physics/3d/default_gravity_vector", Vector3(0,1,0))
or PhysicsServer3D.area_set_param(get_viewport().find_world_3d().space, PhysicsServer3D.AREA_PARAM_GRAVITY_VECTOR, Vector3(0,1,0))
But all my objects who are stationary will not get an impulse. Only if I jump or if a RigidBody object is moved they fly all up.
How can I make sure that all elements get informed about the gravity change and start to fly away?
Add them to a group of any name you want and use get_tree().call_group()
In any script that needs to react the gravity change:
func _ready() -> void:
add_to_group("gravity_change") # Can be any other name you want
func gravity_changed() -> void:
# Do what you need to do when the gravity change
And when you do the gravity change you can call: get_tree().call_group("gravity_change", "gravity_changed")
Thanks for your quick answer.
Now let’s assume I have a few RigidBodies3D. They already fell onto the ground. Now I execute the gravity_changed() function… but what should be in there?
I don’t wan’t do apply forces, I just want that physics take over.
Or could i trigger that by adding just a tiny tiny impulse?
