I have a question about backgrounds

[[BKs]Castello]

So, I, like a good fan of Super Smash Bros. (for those who do not know is a game that started the Nintendo 64 fighting momentum) like a lot of backgrounds that interact with the characters somehow.
So I am trying to learn to create backgrounds that interact with the characters, as some are already available on site lf-empire.

Ando studying hard the bgs that already exist (like the Realm of fog, Spirit Trail, the Lion Forest in the storm) I'm just struggling to heed as the "bg.dat" is connected to others ".dat" that generate the map interactivity?

I tried some "opoint" or "oid" that relates the two things but did not.

I'm trying to create a background of the beach, which will briefly be waves, but I can not call them. dat so the bg.dat is not reading them. dat wave.

Sorry if this explanation is in some tutorial in lf-empire, but I have not found anywhere else.

Please if someone can help me I appreciate it.
