Tilesets... Need help... [Resolved]

[Halestorm5]

Ok, so I know what the X and O means but I have a problem...

1. What does the [] (Square) mean?
2. What does Passage (4 dir) mean?
3. What does all of the other things mean?

Please help... 
(Basically what I need is a tut...)

Ok square setting is for things along the lines of walls (it will be over you from behind, but under you in front).

The four little arrows allow you to set passability, the arrow means you can walk into the tile from that direction.

What other things? Be specific and perhaps I'll help =)

X means impassable if I remember correctly.

Yes, X is non passable thing, O is passable thing, The RPG MAKER Arrow is what Ds said.

and also teh square
