* make setting the line ID with P_TranslateLineDef explicit because there's one FraggleScript function that needs to work around the changes caused by this. There's also some functions setting only a temporary linedef. These would inevitably cause problems if the underlying data gets changed.
* remove FS function 'ChangeTag'. Fortunately this was just some long forgotten test stuff that can be removed without affecting any maps, but the feature would cause some serious problems in a more complex system.
With these changes it is guaranteed that after map setup the tag/ids won't change anymore.
This is done to encapsulate the gory details of tag search in one place so that the implementation of multiple tags per sector remains contained to a few isolated spots in the code.
This also moves the special 'tag == 0 -> activate backsector' handling into the iterator class.
- Old mess:
* Execute autoexec files right away.
* Execute -exec files right away.
* Execute command line commands right away.
- If, during any of the above, an unknown command or a set of an
unknown variable is encountered, store it for later.
- Pullin commands are directly executed and add to the list of files
to load.
* Do a little setup, including parsing CVARINFOs.
* Retry saved commands in case CVARINFO added a cvar they refer to.
- New, less messy, mess:
* Parse autoexec files into an array.
* Parse -exec files.
* Parse command line commands.
- During all of the above, exec commands are also parsed into the
array immediately rather than being saved for execution later.
- Pullin commands are parsed into a different array. The pullin
command doesn't actually do anything directly anymore.
* Add all the pullin files to the list of files to load.
* Do a little setup, including parsing CVARINFOs.
* Execute every command that was parsed in the preceding steps.
Both 'Adventures of Square' IWADs were missing an entry for base MAPINFO and as a result did not define the common editor numbers.
To prevent this, a new mindefaults MAPINFO was added to zdoom.pk3 which now gets loaded if IWADINFO does not specify a game-specific file.
This minimum setting sets all gamedefaults to a reasonable base value and defines all other things that are required to be defined.
This has an important implication:
Previously the config was loaded before IWADINFO so in order to allow the config to access the data this had to be switched around.
This means that zdoom.pk3 will not be looked for in the global IWAD search paths anymore, but since it shouldn't be there to begin with it should be an acceptable compromise.
As a result the old 'Group' property could be removed and all other means to get a section name were disabled.
As an example, if the code gets 'doom.doom2.commercial' it will use the following sections in this order:
global.autoload
doom.autoload
doom.doom2.autoload
doom.doom2.commercial.autoload.
