I was following a video tutorial that shows how to make an switch skill bar in godot but every time i run the game i just get this error " Invalid operands String and Nil in operator +"
i tried to command the skill_name to be converted to a string for this purpose using load(“res://graficos/Skills/” + str(skill_name) + “.png” but i m getting this other error, “Invalid type in Vector 2 constructor. Cannot convert argument 1 from nil to float”
Sorry if i cant explain better im still a beginner
extends RigidBody2D
var axe_speed
var life_time = 3
var damage
var skill_name
#var fire_direction
#func _init(_skill_name):
# skill_name = _skill_name
func _ready():
match skill_name:
"Spear":
damage = 40
axe_speed = 200
"Axe":
damage = 30
axe_speed = 400
var skill_texture = load("res://graficos/Skills/" + skill_name + ".png")
get_node("Projectile").set_texture(skill_texture)
apply_impulse(Vector2(), Vector2(axe_speed, 0).rotated(rotation))
self_destruct()
func self_destruct():
yield(get_tree().create_timer(life_time),"timeout")
queue_free()
func _on_Taxe_body_entered(body):
get_node("CollisionPolygon2D").set_deferred("disabled", true)
if body.is_in_group("Enemies"):
body.on_hit(damage)
self.hide()
and in the player script i have this
func skill_loop():
if Input.is_action_pressed("shoot")and can_fire == true:
can_fire = false
throwing = true
speed = 0
get_node("PlayerAxis").rotation = get_angle_to(get_global_mouse_position())
var axe_instance = axe.instance()
axe_instance.position = get_node("PlayerAxis/axePosition").get_global_position()
axe_instance.rotation = get_angle_to(get_global_mouse_position())
axe_instance.skill_name = selected_skill
get_parent().add_child(axe_instance)
yield(get_tree().create_timer(rate_of_fire),"timeout")
can_fire = true
throwing = false
speed = 70
The error does seem like your skillname is nil and i see you are setting it in the player script to whatever selected_skill is, i would double check selected skill before it is set into the skill name with either a debugger or by printing it’s value to the console.
