Hello, beginner godot’er here.
I’m making a game about gravity. So far I have a scene with 2 rigidbodies, a planet and the player. On the player I have a script based on tutorials I found that goes like this :
func _process(delta):
direction_playerplanet = (planet.position - position).normalized()
distance_playerplanet = planet.global_position.distance_to(global_position)
f = G * ((mass_planet * mass_player) / (distance_playerplanet * distance_playerplanet))
func _integrate_forces(state):
set_applied_force(thrust.rotated(rotation))
set_applied_torque(rotation_dir * spin_thrust)
state.add_central_force(f * direction_playerplanet)
So this works but clearly its only between those two rigidbodies. I would like to be able to have the player attracted to multiple objects as well as having objects attracted to each other. How do I do that ?
Thanks
One thing that came into my mind is that you could just loop through all those objects (player, planets, suns e.g.) in every object’s code (or maybe attach the same script to them?) and calculate the force that way. You could use groups for this: add_to_group("something") and for body in get_tree().get_nodes_in_group("something"): ... if I didn’t mess it up
( SceneTree — Godot Engine (stable) documentation in English )
but there may be better approaches
