finally done. Now, time to start clearing as much as possible
|
|
including a new toolbar, accessible from the map menu or Ctrl X. Patch by Wolf01.

The end of the preliminary work is near
|
|
and you are working on the ground tile, do not take aircrafts into account, as they do not pose any danger for the construction/destruction/conversion itself. Z stuff, in other words
|

|
functions: Changed the order of error checks to generate more meaningful error messages, added some doxygen comments and replaced bitshifting by proper mathematical operations

landscape types.

climate, supplied
by newgrf files. When this is enabled forests cannot be built below the highest
snow line, and farms can't be built above it. Houses still use the
_opt.snow_line so they are all consistent, so to make them respect the snowline
you may want to use some newhouses features as well.

coding style (and rest of the code).

tiles, unification of ground type between normal rail tiles and depots/waypoints and removing the need for RailTileSubType.
|
|
a map accessors header.
|
|
Replace tests with magic numbers by a simple extraction template for command parameters
|
|
Remove unnecessary EnsureNoVehicle() checks because they are
- pointless per se (f.e. there are no vehicles on house tiles)
- done again (f.e. using CMD_LANDSCAPE_CLEAR just a few lines later)
|
|
CLRBIT() and so on (modify value of the first parameter instead or returning the result)
|
|
Remove {,u}intswap() and replace them by Swap()

bitshuffling occurred. Also update with other station drawing changes (code duplication,
eh?)

circumstances (not the proper bits of p1/p2 were set to trackbits). Moved trackbits back to bits 0..2, ctrl to 3, semaphore to 4. Also lower the decision of the ctrl-override of signal/semaphore from the GUI into the cmd function since we are passing the ctrl-bit anyways. Bug(s) found by Frostregen; thanks

inside the CMD_ functions where they are supposed to be. Achieve this by adding a seperate bit to p1/p2 to hold the CTRL-modifier. While here, use proper types, and 'unify' the parameter bit-meanings. 0 - ctrl-pressed, 1 - signal/semaphore, 2-4 - trackbits, 5 - remove (internal), 24-31 - drag density.

values.
This lets us increase the sprite width from 14 to up to 29 bits,
effectively nulling the old sprite limit. Table changes in next commit.

accept pointer to TrackBits/TrackdirBits instead of reference.
