So, I recently started using Godot and I decided that I want to start my game developer jouney from making turn based RPGs. I decided to start with making grid based movement following this tutorial: (https://www.youtube.com/watch?v=JtnnKVxoH5k).
In the end, my code is basically exactly the same as in the video(in the video, the code is completed at 15:56), but for some reason “Invalid call. Nonexistent function “is_colliding” in base “GDScriptNativeClass”” pops out when I try to lunch the game. I have a feeling the problem might be in a typo, but either I can’t see it, or the problem is in something else.
What’s wrong?
Here is my code
extends Sprite
var speed = 200
var tile_size = 20
var last_pos = Vector2()
var target_pos = Vector2()
var movedir= Vector2()
onready var ray = RayCast2D
func _ready():
position = position.snapped(Vector2(tile_size, tile_size))
last_pos = position
target_pos = position
func _process(delta):
#move
if ray.is_colliding():
position = last_pos
target_pos = last_pos
else:
position += speed * movedir * delta
if position.distance_to(last_pos) >= tile_size - speed * delta:
position = target_pos
#idle
if position == target_pos:
get_movedir()
last_pos = position
target_pos += movedir * tile_size
func get_movedir():
var L = Input.is_action_pressed("ui_left")
var R = Input.is_action_pressed("ui_right")
var U = Input.is_action_pressed("ui_up")
var D = Input.is_action_pressed("ui_down")
movedir.x = -int(L) + int(R)
movedir.y = -int(U) + int(D)
if movedir.x != 0 && movedir.y != 0:
movedir = Vector2.ZERO
if movedir != Vector2.ZERO:
ray.cast_to = movedir * tile_size / 2
From the error, it looks like the variable ray is of the type GDScriptNativeClass. Though how it gets assigned that is beyond me.
