So far all the help that I have received here has worked in my game and I really appreciate, I would like to ask another question, I am building a pyramid level, this level is filled with traps, like fire and falling walls, I would like to build a box that shoots spears and keeps repeating by creating another spear after a couple of seconds, also I would like that the spears that the box creates disappear after a couple of seconds how would make a code for this ?
