[Super-tux-devel] File format

[<ri...@ae...>]

Hey there,=20
=20
 To implement tiles like the ones decribed in the development page,=20
I think we need to:=20
- create a config file with all the tiles and the information about=20
them;=20
- make tiles code flexible;=20
- improve collisions between tiles and the player.=20
=20
=20
 My point is that we need a file format, since the level and=20
highscore ones should be more flexible and use a common system to=20
read them.=20
 In my opinion, we don't need a very complex file format, so I vote=20
for a kde/windows (.ini) like file format.=20
 This is how my BobbleBubble game levels looks like:=20
