* there is a new crushing mode 3, which means that the crusher will always slow down if it hits an obstacle.
* crushing mode 1 (Doom mode) will never slow down.
* crushing mode 0 (compatibility) will only slow down for the specials that did so before, and only if both up and downspeed are 8 and the game is not Hexen. The following specials are affected:
* Ceiling_LowerAndCrush
* Ceiling_LowerAndCrushDist
* Ceiling_CrushAndRaise
* Ceiling_CrushAndRaiseA
* Ceiling_CrushAndRaiseDist
* Ceiling_CrushAndRaiseSilentA
* Ceiling_CrushAndRaiseSilentDist
* Generic_Crusher was fixed to act like in Boom: Not only a speed value of 8 will cause slowdown, but all speed values up to 24.
* Hexen crushing mode will never cause slowdowns because Hexen never did this. (which also makes no real sense, considering that the crusher waits for the obstacle to die.)
- Includes 2 flags, affixed by CBF_: AbsolutePos, and AbsoluteAngle.
- AbsolutePos: Absolute position of where to check.
- AbsoluteAngle: Angle parameter is used as is, not added onto the actor's current angle.
* Added falloff parameter to A_QuakeEx.
- Treated just like A_Explode's 'fullradiusdamage' parameter, where the quake will fall off from this distance on out to the edge. Default is 0, which means no falloff.
- Credits to MaxED and Michaelis for helping.
* - Added HighPoint parameter to QuakeEx.
- Allows fine tuning of where the quake's maximum or minimum occurs, in tics. This must be a range between [1, duration).
- For up or down scaling quakes, this sets the quake to reach maximum sooner or start minimizing later.
- For both, this indicates when the strongest will occur. Default is 0, or in the middle.
The original commits were nearly impossible to find in the convoluted commit tree, so I think it's preferable to have one clean commit instead.
- Having my edits to the grammar disappear because Visual Studio had
opened the copy instead of the original was super annoying. Using the -C
option with Lemon, this problem is avoided because there are no copies
to worry about.
- Enhance Lemon so that it reorders the reduce rules such that rules without actions occur at the end and so that the first rule is number 0. This reduces the size of the jump table on the reduce switch, and helps the parser to run faster. (user: drh)
- Enhance Lemon so that if reduce code contains a comment of the form "/*A-overwrites-X*/" then a LHS label A is allowed to overwrite the RHS label X. (user: drh)
- In Lemon, add the ability for the left-most RHS label to be the same as the LHS label, causing the LHS values to be written directly into the stack. (user: drh)
- Improve the Lemon parser template (lempar.c) so that it avoids unnecessary work when the grammer defines YYNOERRORRECOVERY (as SQLite does). Slightly smaller and faster code results. (user: drh)
- Avoid recursion in the yy_find_shift_action() routine of the Lemon-generated parser, so that routine can be inlined, for a size reduction and performance increase. (user: drh)
- Fix uses of ctype functions (ex: isspace()) on signed characters in test programs and in some obscure extensions. No changes to the core. (user: drh)
- For the Lemon-generated parser, add a new action type SHIFTREDUCE and use it to further compress the parser tables and improve parser performance. (user: drh)
- Enhance the "lemon" executable so that it ignores -f, -W, -O, and -I command-line options. This permits most of the same options that are passed to the compiler to also be harmlessly passed to lemon, and thus simplifies makefiles. (user: drh)
- Modify the %nonassoc directive in lemon so that it generates a run-time error rather than a parsing conflict. This changes is due to a bug report on the mailing list. SQLite does not use the %nonassoc directive in its grammar so this change does not affect SQLite. (user: drh)
- In LEMON, limit the size of the grammar file to 100MB. This ensures that the program will never experience integer overflow. To be doubly sure, use calloc() instead of malloc() when allocating arrays. (user: drh)
