hi, i'm doing a game candy-crush like for a school project. And i have gotten this error:
Invalid call. Nonexistent function 'take_damege' in base 'Node2D'.
Apparently i have a function that my script is not reading. They are separated in two scripts but i don't think thats the problem. the two codes:
func _on_Grid_damage_ice(board_position):
if ice_pieces[board_position.x][board_position.y] != null:
ice_pieces[board_position.x][board_position.y].take_damage(1)
if ice_pieces[board_position.x][board_position.y].health <= 0:
ice_pieces[board_position.x][board_position.y].queue_free()
ice_pieces[board_position.x][board_position.y] = null
and
export (int) var health
func _ready():
pass # Replace with function body.
func take_damage(damage):
health <= damage
So the "take_damage" is been call invalid for some reason
anything that can help i would be grateful.
Edit: heres the principal script:
#state machine
enum {wait, move}
var state
# Grid Variaveis
