I am new here, and I wanted to start with a defeat enemies to gain boxes, containing items. Is there a certain way to build these items with non-script? The items, not anything else. And can I have an action code for fighting an enemy, and at least how I am supposed to make an enemy?
I suggest you follow the excellent burgzergarcade’s tutorials that covers these subjects in just an hour or so, in the first tutorials. You can even download the first 10 episode’s scripts if you subscribe.
