Hey! I made a quick video for you, hopefully it's helpful...I've had a few beers lol. From the few reviews I've seen on Pixel Maker, I'm weary about buying it until the full versions out. It looks like it's got some serious Bethesda sized bugs right now haha.
No problem man, I hope it's easy to understand. It was one of the first things I learned how to do before I started making games with rpg maker. I was worried about size restrictions, and there is little to no youtube videos on this. I keep telling myself I should start a youtube channel for rpg maker stuff. I'd love to do a playthrough channel and showcase all these great games people like you are making, and aren't getting the attention they deserve :). I've gotta youtube channel I made a few years back for me and my girlfriends band, but the only video that got popular was a sad space jam song I made as a joke lol, it's got like 41k views some how. Anyways I'm rambling on, Good luck man!
