- Takes player argument and only appears on the screen if
they're a display player.
- Uses 4P font when in splitscreen.
- Uses 1P font if not in splitscreen, or player argument
is NULL -- message to everyone.
- Interrupt argument controls whether the message should
overwrite another message that's already playing.
- Global and player specific messages are considered
separately.
SRB2 uses a LOT of mapthing args compared to Hexen (which has none) and ZDoom (which only has them on objects that will never ever activate scripts). So we really badly needed to separate the two if we want attaching scripts to things to be useful.
- Save retry condition in G_BeginLevelExit
- Apply condition in G_FinishExitLevel
Preparation for ACS level end scripts, since the exit
condition will need be known when the countdown starts,
not when it ends (that'd be too late to do anything in the
level).
- ThingCount has an extra argument for sector tag.
- CountEnemies and CountPushables have an extra argument for thing tag.
- Sector tag 0 for CountEnemies and CountPushables now redirects to activator sector.
An immediate level change on command, to the specified level (via string).
Utilises the existing nextmapoverride and skipstats system, but with skipstats assumed to be the default.
More opportunities for early rejection in table-wide searches, in anticipation of future work.
- Many circumstances independently implemented string name comparisons. Most of these have been converted to use R_SkinAvailable, with one exception.
- M_CharacterSelectInit already needs to iterate over the characters, so produce the skin hash independently.
Map things are writeable in Lua, which I am pretty certain is a mistake because mapthings are not sent over the network at all. I considered making them net-synced (it would be relatively easy), but it also aligns with another, more "philosophical" issue: Doom generally copies over properties from mapthing_t into mobj_t, and then only refers to it again when needing to respawn an object -- mapthing_t is not really intended to be referred to very often at runtime. At best it's slightly annoying since some objects rely on a spawnpoint for behavior changes, at worst it may make ACS more confusing in the future since Thing and Mobj tags are mixed together or less useful since they wouldn't be able to modify behaviors of objects that are based on args.
So I decided to solve these two issues at the same time; just treat mapthing_t as something to copy values from, like OG Doom does it. This basically just means that special and args are also part of the mobj now instead of the mapthing, which should fill any desire to edit this stuff from Lua, and reduces the number of instances where objects need to check for their spawnpoint to function properly.
Lines, sides, sectors, and things now all support the "Custom" tab properly. Label a property as `user_[whatever you want]` in this tab, and it will be added to the structure. ACS will then be able to retrieve it using the `Get[x]UserProperty()` function.
stringarg[0] and stringarg[1] are now are used as doubles of arg[0] and arg[1]. Specials that use both string args and regular args need to shift their args up to accomedate. This makes the behavior align more closely with the other Doom ports and removes a dumb manual string arg amount thing in callSpecImpl.
I only adjusted the specials that can be called from ACS. I did not mess with level load specials or thing types, since it's not as important. It would be nice to clean them up before release for consistency, though.
SetLineRenderStyle(int tag, int blend, int alpha)
Changes the blend mode and transparency of a linedef. Requires new compiler config for the blend mode constants.
- POSITION: Runs when POSITION period ends. Has no activator.
- OVERTIME: Runs when the time limit runs out. Has no activator.
- EMERALD: Runs when the Special Stage UFO's Chaos Emerald is grabbed. The activator object is set to the player that grabbed it.
- Previously was extern scope UINT32 for all players, but this permits one player in a netgame taking a secret path while others don't.
- Attempted to make user-specifiable string, but while I can undo the effects of strtok for the condition, I cannot undo the effects of strupr - so it's disabled for now until we come up with a more robust and hopefully direct system.
- Also removed some old SRB2-originated assumptions that you couldn't unlock anything in multiplayer from the unlocktrigger system.
