Summary of changes (For more details and notes, see the full changelog (TAT-v2.0-Beta-Changelog.txt) included in the release):
Fixed extended share menu that wasn't working. Also added hover and floating hover platforms and advanced vehicle plants to the Arm Beaver and Core Muskrat build menus (Thanks Chao!).
Merged Arm and Core underwater nuclear mines with nuclear mines.
NOTE: This frees up two unit slots, and they were identical in every way (cost, model, etc.) except for being able to be built underwater or not.
Arm Solar Collector build angle reduced to 4096 (16384).
Core Solar Collector build angle decreased to 4096 (16384).
Summary of changes (For more details and notes, see the full changelog (TAT-v2.0-Beta-Changelog.txt) included in the release):
The new TADR release is included in this beta, which includes the +autoteam command, metal extractor and wreckage "snap" functionality, etc. This includes a new totala.exe and .dlls to allow for the new functionality. For details, see tdraw.txt.
Depthcharges now continue to track targets outside their range, like missiles, making it harder for subs (Or other units) to outrun them.
Doubled the metal "weight" for being carried in multi-unit air transports (Arm Condor and Core Vindicator) for Arm Lemmings and Invaders and Core Roaches and Skuttles, so you can only carry half as many (10 Lemmings instead of 20, etc.).
Arm Gremlin mincloakdistance increased to 50 (25).
NOTE: This makes them easier to decloak, since it was really difficult before. Now a unit that comes within about a Gremlin's width of the Gremlin should decloak it.
Tripled the energy costs for the Arm Epoch and Core Black Hydra.
NOTE: Previously, Epochs and Black Hydras had the same energy to metal ratio as the Millenium and Warlord, despite the former being Gantry-level ships. Now their energy cost is tripled like other Gantry units.
Core Cauterizer attack run length and turnrate reduced.
NOTE: This should help "chain-bombing" to be less abuseable with the Cauterizer, especially while trying to change directions during it.
Arm Hermes cost reduced, armor increased, and firepower reduced to 1/2. They now use the Arm Chainsaw weapon.
Minelayer vehicles, Kbots, and ships now take 20% normal damage from mines (5% normal damage).
Arm and Core Nexus speed reduced to 1.2 (1.3).
NOTE: This gives them the same speed as Commanders.
Core Tidal Generator footprint changed to 3x3 (4x4), so they take up as little space as an Arm Tidal Generator.
Summary of changes (For more details and notes, see the full changelog (TAT-v2.0-Beta-Changelog.txt) included in the release):
Arm and Core MRUs energy cost increased to match standard energy drain for building advanced vehicles.
The following amphibious units had their energy cost lowered to 50% above baseline instead of 100% above:
Arm Pincer
Arm Pelican
Arm Triton
Arm Marauder
Core Garpike
Core Gimp
Core Shiva
Core Croc
Core Poison Arrow
Arm PomPom and Core Aries had their energy cost increased by 50% and their speed increased by 25% to match the other amphibious units.
Core Gimp speed increased proportionately match the Arm Pelican.
The following advanced tanks have had their armor increased by 50% and their firepower decreased by 50%:
Arm Mumbo
Arm Triton
Arm Demolisher
Core Reaper
Core Poison Arrow
Core Termite
Core Halberd
The Arm Bulldog and Core Goliath have had their armor doubled and their firepower halved.
Arm Sneaky Pete and Veil and Core Castro and Shroud no longer automatically cloak as soon as you start to build them. The T1 and T2 jamming towers were also set to cost twice as much metal and energy as the T1 and T2 radar towers. This reduced the T1 jammers cost and increased the T2 jammers cost.
tdraw.dll is an upgrade for Total Annihilation. It patches the game to fix many bugs and add many features.
It is an integral component of the TA Community Patch, the other parts being tplayx.dll (the recorder) and server.exe (the replayer).
tdraw.dll has a long provenance dating back to the work of SY_Yeha, who introduced whiteboard markers and the TA Hook and new hotkeys to TA.
Later work by Xpoy extended hotkey support, added new shortcut commands, uni-code font support, megamap, weapon-id crack (not present in current release) and porting music patch from GOG version,
and later support was provided by Rime.
The present release includes contributions from Axle and FunkyFresh, and owes a debt to TAG_Venom for extensive testing and critical feeback, and to Gamma and Wotan for further testing and feature suggestions.

Per-rotation overrides are also available — useful when the visible
pieces should differ by facing. Use any of:
PreviewPiecesS=... facing south (rotation 0)
PreviewPiecesE=... facing east (rotation 1)
PreviewPiecesN=... facing north (rotation 2)
PreviewPiecesW=... facing west (rotation 3)
Lookup order for the active rotation:
1. PreviewPieces<S|E|N|W>= if set (non-empty), uses ONLY that list.
2. PreviewPieces= the default for every rotation.
3. neither set every piece minus the ephemeral filter.
For units whose Create() script auto-rotates the structure toward
the nearest enemy Commander, the preview can be made to face the
same direction — preventing the jarring snap when the build commits
— by adding:
[UNITINFO]
{
...
PreviewFaceOpponent=1;
}
At each preview frame we find the nearest enemy commander to the
build cursor (each enemy player's first unit slot, which is the
commander in all but pathological cases), and snap the line from
the cursor to that commander to the nearest cardinal (S / E / N /
W). PreviewFaceOpponent overrides the Rotations= restriction —
setting this key is the author's explicit signal that the unit's
heading is script-driven, so the preview must face whichever
cardinal the script will pick regardless of what Rotations= permits
the player to cycle through.
To avoid leaking enemy positions through fog-of-war scanning, the
override only applies when the build cursor is within the actual
builddistance of one of the local player's selected, completed
construction units (each builder gets its own threshold from its
FBI builddistance=). Outside that radius the preview falls back to
the player's rotate-build selection — same as if PreviewFaceOpponent
were unset.
Falls back to the player's rotate-build selection in single-player
or any case where no enemy commander can be found (e.g. all enemies
dead).
Mod authors who want the preview to display a completely different
model than the unit's actual Object3D= (e.g. a simplified silhouette,
or the upgraded form of a unit whose 3DO bundles multiple variants)
can name an alternative 3DO with a "PreviewObject3D=" key:
[UNITINFO]
{
...
PreviewObject3D=corarmvp_preview;
}
The value is a 3DO base name (no extension); the file is loaded from
the HPI archive at objects3d/<name>.3DO on first use and cached
for the rest of the game session. All other preview FBI keys
(PreviewPieces, PreviewFaceOpponent, etc.) apply to this overridden
model — piece-name whitelists are matched against the OVERRIDE 3DO's
piece names, not the unit's real one.
If the named 3DO can't be found in the HPI, a warning is logged to
tdrawlog.txt and the preview falls back to the unit's real model;
no other behaviour is affected.
