What I meant was this: For example, I clicked left click and the axe came to my hand as a static mesh: For example, I clicked left click and the axe came to my hand as a static mesh. ok, there is no problem there. but when I click left click again when I have the axe in my hand, how will I make the attack function? or when I leave the axe immediately and take a syringe, when I click left click, it will start using the item and add health to the character when the animation is over? Ok I know interfaces and blueprint communication but I don’t understand how to do it.
