pick sprite dep. on adjecent one ? Help!

[Dante123]

Pretty basic question:
For station tiles, how do i pick a sprite depending on a specific one that is adjacent to it ?

for example i have 4 ways of placing a Bufferstop tile (NE-SE-SW-NW)
now i know how i can code it as pairs, but in that case it will be 2 separate station ID numbers.
i know of some sets that already do that trick (Japanese set/ISR set/...) they have it auto picked once specific tiles are built next to it (so it does not count for any station tile that is next to it)

but i have no idea what action to use for this, (my guess would be action 9 ? ) and i have no idea how it should be looking like.

is there someone that can explain just a bit and maybe (please) add some example code ?

You'll need to make use of an varaction2 sequence to decide upon the sprite to be used. Probably variables 45 and 68 and maybe 67 will help you. See http://wiki.ttdpatch.net/tiki-index.php ... y_tiles_68_

im really lacking coding skills to code something from scratch

maybe anyone can help me with some code example i can look at to be able to understand how it works ?

Right... you basically link from the Action3 to the varaction2 which then checks the variable(s), can branch further to further variable check until you (finally) branch to a normal action2. Here an example from a train which I coded, where I check the year in order to decide the sprite being drawn:

Code: Select all

1547 * 9 03 00 01 FF \wx0074 \b0 \wx00F8  // action3, (vehicleID 0x74), use (var)action2 ID 0xF8)

Similar you can do that for a station, sprite with your variables, too.

i was also looking at the buffers now how industrial station renewal did it.

his code looks like this:

Code: Select all

the part i should be looking at is the part between // - - - -
will try to make sense out of that with the wiki and you code

How about the pictures then? Sometimes, enlightenment comes by sound or touch, it may also come by watching pictures.
