I have completed an godot tutorial and have successfully produced a simple game demo.
However, when I am trying to add in my own design – a healing action that stops the player from moving and regain health after a duration of time. The engine says
“Invalid type in function ‘move_and_slide’ in base ‘KinematicBody2D (operation.gd)’. Cannot convert argument 1 from int to Vector2.”
I don’t really understand why it suddently crashed because I used the same structure as how other actions are designed.
the code is a bit long so I hope noting will help understanding it:
extends KinematicBody2D
const acceleration = 400
const maxspeed = 60
const friction = 500
const roll_speed = 120
const player_hurt_sound = preload("res://Action RPG Resources/Music and Sounds/special_sound_effect.tscn")
#set up basic variables that makve moving more realistic
#to change initial health check Player_stats
enum{
move
roll
attack
heal
}
