* `Restart' is now an undo-able action: it appends a move to the endSimon Tatham2005-05-17
| | | | | | | | | | | | | | | | | | | | of the undo list rather than destroying it. Partly this is because accidental restarts are a real pain, and partly because it allows you to compare the initial to the current state by restart-then-undo which is handy in some puzzles. In order to do this, I've introduced an additional per-entry field in the undo list in the midend, which tracks which states were created by `unusual' operations (Solve and Restart). The midend takes care of suppressing animation and completion flashes during transitions between a `special' state and its predecessor, relieving the game backends of having to do it individually. (This probably means I could remove some complexity in the flash_time() functions in most backends, but I haven't done that in this checkin.) [originally from svn r5791]

* Cube's dup_game() function was missing a field. Oops.Simon Tatham2005-05-17

* The game IDs for Net (and Netslide) have always been random seedsSimon Tatham2005-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rather than literal grid descriptions, which has always faintly annoyed me because it makes it impossible to type in a grid from another source. However, Gareth pointed out that short random-seed game descriptions are useful, because you can read one out to someone else without having to master the technology of cross- machine cut and paste, or you can have two people enter the same random seed simultaneously in order to race against each other to complete the same puzzle. So both types of game ID seem to have their uses. Therefore, here's a reorganisation of the whole game ID concept. There are now two types of game ID: one has a parameter string then a hash then a piece of arbitrary random seed text, and the other has a parameter string then a colon then a literal game description. For most games, the latter is identical to the game IDs that were previously valid; for Net and Netslide, old game IDs must be translated into new ones by turning the colon into a hash, and there's a new descriptive game ID format. Random seed IDs are not guaranteed to be portable between software versions (this is a major reason why I added version reporting yesterday). Descriptive game IDs have a longer lifespan. As an added bonus, I've removed the sections of documentation dealing with game parameter encodings not shown in the game ID (Rectangles expansion factor, Solo symmetry and difficulty settings etc), because _all_ parameters must be specified in a random seed ID and therefore users can easily find out the appropriate parameter string for any settings they have configured.

* Introduce a versioning mechanism, and an `About' box in all frontSimon Tatham2005-05-15
| | | | | | | | | ends. Versioning will be done solely by Subversion revision number, since development on these puzzles is very incremental and gradual and there don't tend to be obvious points to place numbered releases. [originally from svn r5781]
* I've had two complaints that Solo ought to recognise the numericSimon Tatham2005-05-12
| | | | | | | | | | | | | | | | keypad. The reason it doesn't is because front ends were carefully translating the numeric keypad into 8-way directional keys for the benefit of Cube. Therefore, a policy change: - front ends process the numeric keypad by sending MOD_NUM_KEYPAD | '3' and similar - front ends running on a platform with Num Lock SHOULD do this _irrespective_ of the state of Num Lock - back ends do whatever they see fit with numeric keypad keys. Result: the numeric keypad now works in Solo, and also works in OS X Cube (which it previously didn't because I forgot to implement that bit of the front end!). [originally from svn r5774]
* The two Rubik-like puzzles, Sixteen and Twiddle, now support anSimon Tatham2005-05-11
| | | | | | | | | | | | | additional configuration parameter, which is the number of shuffle moves. By default the grid will be fully shuffled so that you need a general solution algorithm to untangle it, but if you prefer you can request a grid which has had (say) precisely four moves made on it, and then attempt to exactly reverse those four moves. Currently this feature is only available from the Custom box, and not in any presets. [originally from svn r5769]
* Bah. Try the r5766 fix again, this time without the typo.Simon Tatham2005-05-11

* Completion flashes were occasionally failing to be cleaned up if aSimon Tatham2005-05-11

* solve_game() is passed the _initial_ game state, not the most recentSimon Tatham2005-05-07
| | | | | | | | | | | | | | one; so we can't just set `ret->completed = ret->movecount' and hope it's been set to something other than zero. Instead, we set both move counts to 1, which is entirely arbitrary but works. This fixes a subtle bug with the Solve feature: if you pressed Solve, then disturbed the grid, then brought it back to the solved state by making more forward moves (rather than using Undo), then the first time you did this the `Moves since auto-solve' status line would reset to zero. [originally from svn r5759]

| | | | | | | | | | the missing fifth difficulty level to Solo: `Unreasonable', in which even set-based reasoning is insufficient and there's no alternative but to guess a number and backtrack if it didn't work. (Solutions are still guaranteed unique, however.) In fact it now seems to take less time to generate a puzzle of this grade than `Advanced'! [originally from svn r5756]

* The Twiddle shuffling algorithm was theoretically parity-unbalanced:Simon Tatham2005-05-04
| | | | | | | | | | | | | it performed a fixed number of shuffling moves, and on each one it had a 2/3 chance of flipping the permutation parity and a 1/3 chance of keeping it the same. Markov analysis shows that over a run of 1500-odd shuffle moves this will end up being an undetectably small actual bias in the parity of the generated grid, but it offends my sense of pedantry nonetheless so here's a small change to make the number of shuffling moves itself have randomly chosen parity. The parity of generated grids should now be _exactly_ 50:50. [originally from svn r5742]

| | | | | | | | | | | | | | | | various things: - if you haven't fully understood what a game is about, it gives you an immediate example of a puzzle plus its solution so you can understand it - in some games it's useful to compare your solution with the real one and see where you made a mistake - in the rearrangement games (Fifteen, Sixteen, Twiddle) it's handy to be able to get your hands on a pristine grid quickly so you can practise or experiment with manoeuvres on it - it provides a good way of debugging the games if you think you've encountered an unsolvable grid!
