of its segs thrown away, so the map could not start. This was because the nodebuilder assumed all subsectors would be 2D and could not handle the case where a degenerate 1D subsector is created. In this case, that happens because that map has three polyobjects in the middle of the void, so the only way to assign them to a subsector is to use a 1D subsector. SVN r153 (trunk)

|
|
** used if there are fewer than 250 terminals
|
|
** and nonterminals. "int" is used otherwise.
|
|
** YYNOCODE is a number of type YYCODETYPE which corresponds

|
** number is used to fill in empty slots of the hash
|
|
** table.
|
|
** YYFALLBACK If defined, this indicates that one or more tokens
|
|
** have fall-back values which should be used if the
|
|
** original value of the token will not parse.
|
|
** YYACTIONTYPE is the data type used for storing terminal
|
|
** and nonterminal numbers. "unsigned char" is
|
|
** used if there are fewer than 250 rules and
|
|
** states combined. "int" is used otherwise.
|
|
** ParseTOKENTYPE is the data type used for minor tokens given
|
|
** directly to the parser from the tokenizer.
|
|
** YYMINORTYPE is the data type used for all minor tokens.
|
|
** This is typically a union of many types, one of
|
|
** which is ParseTOKENTYPE. The entry in the union
|
|
** for base tokens is called "yy0".
|
|
** YYSTACKDEPTH is the maximum depth of the parser's stack.
|
|
** ParseARG_SDECL A static variable declaration for the %extra_argument
|
|
** ParseARG_PDECL A parameter declaration for the %extra_argument
|
|
** ParseARG_STORE Code to store %extra_argument into yypParser
|
|
** ParseARG_FETCH Code to extract %extra_argument from yypParser
|
|
** YYNSTATE the combined number of states.

** YYNRULE the number of rules in the grammar

|
|
** functions that take a state number and lookahead value and return an
|
|
** action integer.
|
|
**
|
|
** Suppose the action integer is N. Then the action is determined as
|
|
** follows
|
|
**

** 0 <= N < YYNSTATE Shift N. That is, push the lookahead
|

**
|
|
** N == YYNSTATE+YYNRULE+2 No such action. Denotes unused
|
|
** slots in the yy_action[] table.
|
|
**
|
|
** The action table is constructed as a single large table named yy_action[].
|
|
** Given state S and lookahead X, the action is computed as
|
|
**
|
|
** yy_action[ yy_shift_ofst[S] + X ]

|
**
|

** If the index value yy_shift_ofst[S]+X is out of range or if the value
|

** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X or if yy_shift_ofst[S]
|
|
** is equal to YY_SHIFT_USE_DFLT, it means that the action is not in the table
|
|
** and that yy_default[S] should be used instead.
|
|
**
|
|
** The formula above is for computing the action when the lookahead is
|
|
** a terminal symbol. If the lookahead is a non-terminal (as occurs after
|
|
** a reduce action) then the yy_reduce_ofst[] array is used in place of
|
|
** the yy_shift_ofst[] array and YY_REDUCE_USE_DFLT is used in place of
|
|
** YY_SHIFT_USE_DFLT.
|
|
**
|
|
** The following are the tables generated in this section:
|
|
**
|
|
** yy_action[] A single table containing all actions.
|
|
** yy_lookahead[] A table containing the lookahead for each entry in
|
|
** yy_action. Used to detect hash collisions.
|
|
** yy_shift_ofst[] For each state, the offset into yy_action for
|
|
** shifting terminals.
|
|
** yy_reduce_ofst[] For each state, the offset into yy_action for
|
|
** shifting non-terminals after a reduce.
|
|
** yy_default[] Default action for each state.
