Question
I’m trying to add drift the player character. As a first I want to figure out which way the character is turning. :
# Calculate drift --------------------------------------
var angle_diff = snapped(velocity.angle(), 0.01) - snapped(direction.angle(), 0.01)
if angle_diff < 0: #right
pass
print("right")
else:
pass
print("left")
print("direction_angle: ",direction.angle())
print("velocity angle : ", velocity.angle())
print("angle diff: ", angle_diff)
Although when the player is turning left and has the direction (-1,0) the angle diff returns -6
but when turning right and has the direction (-1,0) the angle diff returns 0. And i cant figure out how to fix it
Full script:
extends CharacterBody2D
const SPEED = 300.0
const TURN_SPEED = 8.0
# Driving vars
var max_speed = 800
var speed = 200
var acceleration = 50
var deceleration = 0.1
var direction
var latest_direction = Vector2(0,0)
func _physics_process(delta):
direction = Input.get_vector("ui_left","ui_right","ui_up","ui_down")
if direction:
# Get the angle to the desired direction
var target_angle = direction.angle()
# Smoothly rotate towards that angle
rotation = lerp_angle(rotation, target_angle, TURN_SPEED * delta)
if direction:
var target_velocity: Vector2 = transform.x * max_speed
velocity = velocity.move_toward(target_velocity, acceleration)
# Calculate drift --------------------------------------
var angle_diff = snapped(velocity.angle(), 0.01) - snapped(direction.angle(), 0.01)
if angle_diff < 0: #right
pass
print("right")
else:
pass
print("left")
print("direction_angle: ",direction.angle())
print("velocity angle : ", velocity.angle())
print("angle diff: ", angle_diff)
# --------------------------------------------------------------------------
# Apply standard deceleration
velocity = velocity.move_toward(Vector2.ZERO, deceleration)
# --------------------------------------------------------------------------
if direction != Vector2(0,0):
latest_direction = direction
move_and_slide()
Any and all help is appreciated
