- Polyobject carrying set lastlook on mobjs for internal
tracking
- lastlook is used by some objects to track their own
state
- Ring Shooter uses lastlook to remember which player
summoned it
- A Ring Shooter spawned right next to a polyobject would
become buggy; If its owner player pressed the respawn
button again before the Ring Shooter despawned, that
player would be teleported back to the Ring Shooter
instead of spawning a new Ring Shooter (which would be
the correct behavior)
If player is in one of these states:
- Invincibility
- Grow (K_IsBigger)
- Flame Shield dash
- Over 200% speed
And the other object:
- Does not have MF_DONTPUNT
Then, touching a solid object:
- Punts the object, unless the object has MF_ELEMENTAL
- Fizzles the object, if the object has MF_ELEMENTAL
Or, when an object damages the player:
- That object is punted, unless it has MF_ELEMENTAL
- The object fizzles, if it has MF_ELEMENTAL
Punting means:
- A copy of the object is made
- Both the player and copy receive 5 tics of hitlag
- The copy is thrust away from the player at a minimum of
60 FU, or 2x either the player's or object's momentum,
whichever is ultimately greater
- The copy despawns after 2 seconds
- The copy flickers constantly, while thrust away
Fizzling means:
- The object disappears completely
- A puff of smoke is spawned in place of the object
- No hitlag is applied to the player
Both punting and fizzling:
- Hide the original object (intangible and invisible)
- The original object reppears after 30 seconds
- For 2 seconds before reappearing, the object flickers
back in, but is still intangible
`Condition1 = UfoAttackMethod [type]`
- "smash a UFO Catcher using only [type]"
- Combine with `Prefix_SealedStar` or `Prefix_IsMap [special stage stage]`
- Shows up as "???"
- Types supported:
- `Boost` - "boost power" (sneakers)
- `Whip` - "Insta-Whip"
- `Banana` - "Bananas"
- `Orbinaut`- "Orbinauts"
- `Jawz` - "Jawz"
- `SPB` - "Self Propelled Bombs"
- Other types could be added on request, these were just the easy ones
In addition, the prototype for P_MobjWasRemoved was moved to `p_mobj.h`.
It's EXTREMELY important that we're able to safely check mobj pointers anywhere a mobj_t is possible to observe, without including the full `p_local.h`...
- There's a freeze cheat bool to freeze everything except for players.
- There's a level freeze bool to freeze literally everything.
- There's a frozen bool on mobj_t to explicitly control freeze status on an object.
Replaced all mentions of starpostnum and Starpost w/ cheatchecknum and CheatCheck (so Ivo can stop asking why we still need it when its going to save our asses on release patches)
- Fix the last few bugs I could find with thing args
- Move version update code
- Rename internal variables to `thing_[string]args` to make older code merge issues more obvious
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.
Adds r_spritefx.cpp
lightlevel should be -255 to 255, relative offset to
normal sector lightlevel.
If RF_ABSOLUTELIGHTLEVEL, mobj_t.lightlevel becomes an
absolute lightlevel in the range 0 to 255.
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.
In levels with tens of thousands of precipmobjs, the
overhead of running a thinker for all of them is too much,
no matter how small the thinker is.
ALL thinking is done inside the renderer now, where it can
be limited by distance. Precipmobjs track the last
leveltime they thunk, so interpolated frames don't think
twice.
There can be very many precipmobjs in a sector. During BSP
rendering, for each sector reached by BSP (the entire
visible level at least), all the precipmobjs would be
iterated and their distance from the camera calculated, to
determine whether they are within draw distance.
The issue with the old approach is that there really are
too many precipmobjs in each sector. By iterating the
blockmap within a certain range instead, precipmobjs
out of view are not iterated at all, saving some time.
Caveat: drawdist_precip is no longer respected as an
exact value, since it must round to the precision of the
blockmap.
List of potentially scary changes:
- Removes snext/sprev for precipmobj_t
- Removes preciplist for sector_t
- Adds bnext/bprev for precipmobj_t
- mobj_t and precipmobj_t field offsets are symmetrical
- Modified P_SetPrecipitationThingPosition and P_SetThingPosition
- The syntax in these functions is kind of wacky
- foflayer offsets the thing from an FOF in its sector.
- foflayer 0 uses the base sector heights.
- foflayer 1 uses the lowest FOF top height, or highest
FOF bottom height when the thing is flipped.
- foflayer 2 uses the second lowest / second highest and
so on.
- Don't clear every tic. This is what P_RemoveTracker is
for.
- Link in P_SpawnMobj. Should cover all cases.
- Remove excess objects. These were leftover from when
Shrink destroyed items. Just track Jawz, SPB and Break
the Capsules.
- Lines can be set to activate when crossing or bumping into them, with distinctions for players, enemies, and missiles+items.
- A new flag has been added to determine if a line special can activate more than once.
- Finish Line + Respawn Line are now handled like other specials. This means that:
- They follow the new line activation rules (so you can potentially have a finish line that you have to bump instead of cross)
- More importantly, they can be called as functions in ACS. (Player_FinishLine and Player_Respawn)
- Fixed linedef flags not being saved in save games.
All typedefs for structs that were present in other header
files have been moved to here. (Except node_t because the
renderer and netcode both define node_t LOL.)
- Randomize banana angles when thrown
- Spin bananas when mid-air
- Add MF_SLOPE flag to control whenever or not pitch/roll are set for an object (replaces MF_BOXICON)
