Currently I am making a clone of the game Flappy Bird for practice. I am representing the bird as a RigidBody2D.
extends RigidBody2D
func _ready():
pass
func _input(event):
if Input.is_action_just_pressed("input_action_flap"):
bird_flap()
func _physics_process(delta):
print(self.rotation_degrees)
self.rotation_degrees = -45
print(self.rotation_degrees)
func bird_flap():
var des_linear_velocity_x : float = get_linear_velocity().x
var des_linear_velocity_y : float = -750
var des_angular_velocity : float = -3
set_linear_velocity(Vector2(des_linear_velocity_x, des_linear_velocity_y))
set_angular_velocity(des_angular_velocity)
I am playing around with ways to limit the possible rotation of the Node. However, I am running into some issues.
-135.234329
-45
-137.498474
-45
-139.724884
-45
+171.914169
-45
+164.066986
-45
The values of the rotation seem to be flickering wildly due to Godot’s built-in physics engine. And when I try to use the method clamp(…) - I subsequently experience wild flickering of my character sprite’s rotation.
self.rotation = clamp(self.rotation, deg2rad(-45), deg2rad(+45))
Does anyone know how to fix this?
I would not rotate the RigidBody2D in your case, but rotate the srpite instead. changin manually rotation of a RigidBody can be unpredicrable, as the rotation is handled by the engine.
In your case, i would use RigidBody2D in character mode to avoid rotation at all, and rotate the sprite of the bird instead. You should be able to manually change and clamp that rotation.
