All I want is a Kyogre animation to appear in the place I made and for it to move forward when the player steps on a spot.
You mean a script tile, right?
It's 1:04 right now, but I'm going to keep it simple:
1) Go into Advance Map, under the events tab. Scroll all the way down, to amount of events. At the bottom there should be something about "Number of scripts." Press the up arrow.
2) Go to the upper left hand corner of the map. There should be a green S tile, if not, click Brendan's head (this will turn person sprites into greenish P tiles, and make warps, signposts and script tiles visible.)
3) Drag the tile to where you want it to be.
4) There should be something about "Var number" and "Var value." Leave Var value alone, and for this test, put in 4050 in Var number. (You won't be doing this all the times, just depending on situation)
5) Write your script in XSE(I'll do an example later)
6) Compile it in XSE
7) Test
I'll add an example script later, I'm tired.
