I’m trying to make a 3d flight controller with a more arcade feel (think Ace Combat or Rogue Squadron). I’m somewhat new to working in 3d in Godot though and I don’t really understand what methods I should be using to achieve this.

I want up and down to control pitch and left and right to be something of a hybrid roll/yaw. I’m setting direction to -transform.basis.z and multiplying that by speed, but when I use rotate_x() with the pitch, the plane itself rotates, but I only move flatly across the world plane rather than climbing up or down as I’m attempting to achieve.

What am I missing here?

    (Not op, just an example)

    I don’t know an optimal answer here. I see various discussions online about flight control variants. However, here is a simple example I set up out of curiosity. Maybe useful? I’d like to hear about what you end up with.

    Project code at: https://github.com/pipehat/godot41_flight_controller_example

    ————————————

    plane controller script:

    
extends CharacterBody3D

var print_delay = 1
var next_print = 0
const SPEED_MPS = 500

func _physics_process(delta):
	var input_dir = Input.get_vector("ui_left", "ui_right", "ui_up", "ui_down")
	
	if next_print <= 0:
		print(input_dir)
		print("-z: ", -transform.basis.z)
		next_print = print_delay
	else:
		next_print -= delta
	
	var roll = -input_dir[0]
	var pitch = input_dir[1]
	
	rotate(transform.basis.z, roll * delta)
	rotate(transform.basis.x, pitch  * delta)

	velocity = -transform.basis.z * SPEED_MPS * delta
	move_and_slide()

        I think I have it working as you describe - in the latest version on GitHub. That is more complete now than the code snippet above. See if that helps.

        True. Just showing roll and pitch. This is not op’s code… oh perhaps that’s the thing op really needs to see though? I’ll update the example to show it…

      Not shown in the code here for simplicity, but in the project I added a little bit of yaw drift when banking.

      I’m sure there’s a more accurate way to simulate all this. Just messin around.

        Now for no good reason I added flaps that rotate with the controls. Definitely feature creepin. I’m out! Good luck op!
