You can start with a simple battle scene using a mix of set move route, show animation, play SE and wait commands. Make two events facing each other and experiment with those commands.
I have also learned something when I was trying what OP asked myself before I post. Why does parallel process takes priority over autorun when I insert set move route command in "Contents" on two individual events while they start simultaneously when I just use "Autonomous Movement" ?
Two events facing each other, the left one is set as autorun and only moves right, the right one is set to parallel process and only moves left. When the map loads, the right one moves first. But if I don't use any move command in "Contents" and use autonomous movement instead, they start moving at the same time (I made sure there is no "wait for completion" rule set)
I don't mean to hijack the topic. I think the answer may also help OP.
