I’m using Godot 4 beta 4.
I have a RayCast2D. I want it to be facing the direction the player is looking at, and I thought that I could do it by changing the value of its rotation property depending on the player’s direction.
I made a dictionary to associate each direction my player can face to an angle.
const DIRECTION_TO_ROTATION : Dictionary = {
Vector2.DOWN : 0,
Vector2.DOWN + Vector2.RIGHT : -45,
Vector2.RIGHT : -90,
Vector2.RIGHT + Vector2.UP : -135,
Vector2.UP : 180,
Vector2.UP + Vector2.LEFT : 135,
Vector2.LEFT : 90,
Vector2.LEFT + Vector2.DOWN : 45,
}
In my physics_process function, I made two variables:
var direction : Vector2 = Input.get_vector("move_left", "move_right", "move_up", "move_down").normalized()
var direction_key : Vector2 = direction.round()
Then, I add an “if” statement:
if direction_key in DIRECTION_TO_ROTATION:
$RayCast2D.rotation = DIRECTION_TO_ROTATION[direction_key]
When I run my scene, the RayCast is pointing at the right direction when I face down, down/left, and down/right, but not in every other direction. Does someone know what I did wrong?
By the way, I added a print($RayCast2D.rotation) at the end of my “if”. When I go up for exemple, the output correctly prints 180, but my raycast appears to be facing at around 135 degrees and collides with things as if it was facing at 135 degrees. Manually putting the raycast orientation at 180 degrees via the editor while the game is running makes it face the right direction in-game.
