i want to know how to fix it. I check remote when i play game. its show me null in equipped item i try to fix it but not a change.

Is null because you are setting it to null:

var hand_equip : HandEquip = null

You are not setting any value for hand_equip after that.

How do i set value for hand_equip to change it when i click.i try to write it but its not working

I don’t know LOL what should be hand_equip? From what I can understand, when you press a button, you equip a different item, possibly on a hand(??). Please provide more details.

Also, when posting your code, use the code formatting for a better read. For example:

@tool
extends Sprite2D

class_name HandEquip

@export var equipped_item : EquippableItem :
set(next_equipped):
print("Equipped ", next_equipped.display_name)
equipped_item = next_equipped
self.texture = equipped_item.texture

func _on_area_2d_body_entered(body):
   if(equipped_item.has_method(“interact_with_body”)):
      equipped_item.interact_with_body(body)

im sorry but like u said its change equip_hand when i pressed button
but its not changing cause its null

Do you mind posting a screenshot of your scene? Maybe it can make easier to understand your case. It’s still unclear to me what should be hand_equip and this is what you need to define. Is this a node? Is in the tree? Are you supposed to instantiate it? Should you get it from a NodePath? Where is this hand_equip object?
