My current code is at the bottom, but here's a description of what I'm trying to accomplish:
I have a 3D RigidBody. When I yaw, I want to rotate it back and forth around the global Y axis. If it's not rotated at all, my current code works. Take a look at this gif: https://imgur.com/a/ypKzOc9
First, I yaw left and right. Then, I pitch up and down. It works correctly. Then, I yaw left, and pitch up, and it flips wildly end over end.
The behavior I want is this (demonstrated in editor): https://imgur.com/a/V3qmBaa
extends RigidBody
var yaw_force = 5
var pitch_force = 5
func _ready():
pass
func _integrate_forces(state):
var yaw_axis = Vector3(0,1,0)
var pitch_axis = Vector3(0,0,1)
if Input.is_action_just_pressed("game_yaw_left"):
state.apply_torque_impulse(yaw_force * yaw_axis)
if Input.is_action_just_pressed("game_yaw_right"):
state.apply_torque_impulse(-yaw_force * yaw_axis)
if Input.is_action_just_pressed("game_pitch_up"):
state.apply_torque_impulse(pitch_force * pitch_axis)
if Input.is_action_just_pressed("game_pitch_down"):
state.apply_torque_impulse(-pitch_force * pitch_axis)
