How to translate the position of a gamepad analog stick to a rotation? (twin stick shooter)

DanteeChaos

I have a 3D sprite model. One of the children of that sprite is a weapon (KinematicBody node). I want to rotate that weapon along the Y axis based on the position of the analog stick. Eg. if the analog stick is pointing to the left I want to point the weapon in the same direction (360 degree coverage). Think games like Enter the Gungeon.

For reference, I'm using an XBox One controller Input.get_joy_axis(0, JOY_AXIS_2) is the X axis Input.get_joy_axis(0, JOY_AXIS_3) is the Y axis

There is an angle property of Vector2 that will get you what you need.

var dir = Vector2(your_axis_x, your_axis_y)
var ang = dir.angle()
get_node("your_sprite").rotation = ang

Hope that helps.

Also, welcome to the forums! Hope you find success with Godot.

If I recall correctly, you can also use cos and sin to calculate the angle:

var direction = Vector2(
	Input.get_joy_axis(0, JOY_AXIS_2),
	Input.get_joy_axis(0, JOY_AXIS_3)
)
var angle = cos(direction.x) + sin(direction.y)
node_to_rotate.rotation = angle
