Question
im making a clone of a game but i got an error from a non-static function:
the function is pause_ghost() in await points_manager.pause_ghost(), and the error says Line 166:Cannot call non-static function “pause_ghost()” on the class “PointsManager” directly. Make an instance instead.
these are the relating pieces of code incase you need it to fix it:
the code where the error is in:
extends Area2D
class_name Ghost
enum GhostState {
SCATTER,
CHASE,
RUN_AWAY,
EATEN
}

scatter()
the code where pause_ghost() is from:
extends Node
class_name PointsManager
var ghost_points = 0
var points = 0
func pause_ghost():
points += ghost_points
get_tree().paused = true
await get_tree().create_timer(1.13).timeout
get_tree().paused = false
thank you!
