For example: you want to invoke the jump () function in the playjumpto code in the Player object that has already been instantiatedPrivate Playjumpto Playjumpto;Private Gameobject playerobj;void Start (){Playerobj = Gameobject.findwithtag ("Player");Playjumpto = playerobj.getcomponent}void Fun (){Playjumpto.jump ();}So that's it, notice that you want to designate the player object tag as a new player, and the jump () function to be public.Methods for

Change position, move out of view, recommend, save Gameobject.setactive (FALSE); To be quoted in advance, or you can not change back ... renderer.enabled = false; Multiple renderers, traverse destroy//If you don't use it.
