Trouble in Terrorist Town
GMod 10 (Fretta) gamemode

*** Description:
Disaster strikes in the Terrorist team! These plucky bomb-planting fighters 
have traitors in their midst who are looking to kill them all! But who are 
the traitors... and who will come out of this alive?

*** Fretta:

TTT is Fretta-compatible, which in this case means players get the chance to
vote in order to switch to a different Fretta gamemode.

If you run a server with only TTT on it, you can disable the voting by putting:
fretta_voting 0
In your server.cfg file. This will pretty much make TTT act like a non-Fretta
gamemode.

*** Installation:
Extract .zip contents into:
  X:\Steam\steamapps\your@account\garrysmod\garrysmod\

Or for a dedicated server:
  X:\srcds\orangebox\garrysmod\

So that you get a \garrysmod\gamemodes\terrortown\ directory, and several
textures are placed under \garrysmod\materials\ (eg. \materials\VGUI\ttt\*).

Only the server needs to manually install it. Clients will automatically
receive the necessary files when they connect.

*** Dedicated server (srcds) preparation:
The gamemode _requires_ CS:S content to be installed. The Garry's Mod wiki
has some information on this (and other srcds setup procedures) here:
  http://wiki.garrysmod.com/?title=Dedicated_Server_Setup#Extra_content
  
Note that in order to run the game in "Detective mode" (ie. extra detective-
like gameplay elements such as hiding who died until the body has been found)
you should enable GMod's ScriptEnforcer functionality. Without it, cheating
will be very easy.

The gamemode includes a ScriptEnforcer manifest file (which defines what
scripts clients are allowed to run), so ideally all you should need to do is
set sv_scriptenforcer to 1.

*** Convars:
(Scroll down for concommands)

Something you should know to understand these settings:

A round in TTT has the following phases:
Preparation phase -> [1] -> Round is happening -> [2] -> Post-round phase.

During the preparation phase players cannot hurt each other or destroy 
explosive props. It's a ceasefire situation while everyone gets a chance to
spread out and gather items.

At [1], the traitors are picked, and newly connected players will spawn as
spectator. After this point the game is on, you could say. It keeps going until
at [2] a victory condition happens: either the traitors win, or the innocents
win, or the timelimit is reached. Then a moment of contemplation and review
occurs in the form of the post-round phase.

**** Round structure convars:

ttt_roundtime_minutes (def. 10):
The time limit for each round, given in minutes.

ttt_preptime_seconds (def. 30):
The length of the preparation phase that occurs after players spawn in and
before traitors are selected and a new round begins. Specified in seconds.

ttt_posttime_seconds (def. 30):
The length of time after a round has ended before the next cycle of begins.
The round report is displayed at the start of this phase. During this phase,
stats/points are no longer tracked. Specified in seconds again.

ttt_round_limit (def. 6):
The max number of rounds until the map is switched (needs a mapcycle.txt).

ttt_time_limit_minutes (def. 75):
The max number of minutes until the map is switched (needs mapcycle.txt)

ttt_spawn_wave_interval (def. 0):
If 0, spawns all players at once, and will attempt to rig extra spawnpoints if
there are not enough. Can result in players spawning in walls.
If larger than 0, spawns players in waves, where each wave spawns as many
players as there are spawnpoints. The time between each wave is the value of the
convar in seconds, so setting it to 5 will mean waves are 5 seconds apart.
Spawn waves are probably the best method for large servers.

IMPORTANT: make sure your ttt_preptime_seconds is large enough to fit all waves
in it. Odd behaviour can occur if that is not the case.

**** Gameplay convars:

ttt_sherlock_mode (def. 1):
Enables a large set of gameplay elements that make the game more
detective-like. Most importantly, when a player dies this is no longer
immediately visible on the scoreboard. Rather, his body has to be found to
confirm his death.

ttt_traitor_pct (def. 0.25):
Percentage of total players that will be a traitor. The number of players will
be multiplied by this number, and then rounded down. If the result is less than
1 or more than the player count, it is clamped to those values.

ttt_traitor_max (def. 32):
Maximum number of traitors. Customize this if you want to finetune the number of
traitors at your server's max playercount, for example to make sure there are
max 3 traitors on a 16 player server. By default there is basically no max.

ttt_detective_pct (def. 0.13):
Percentage of total players that will be a detective (detective
innocent). Handled similar to traitor_pct (rounded down etc).

ttt_detective_max (def. 32):
Maximum number of detectives. Can be used to cap or disable detectives.

ttt_detective_min_players (def. 10):
Minimum number of players before detectives enter play. At lower playercounts it
will be purely normal innocents vs traitors, at higher ones some innocents will
be detective.

ttt_detective_min_karma (def. 600):
If a player's Karma falls below this point, his chances of being selected as
detective are reduced.

ttt_minimum_players (def. 2):
Number of players that must be present before the round begins. This is checked
before the preparation phase starts, and before the actual round begins.

ttt_postround_dm (def. 0):
Enables damage after a round has ended. Kills are not recorded for scoring
purposes, so it's a free for all.

ttt_dyingshot (def. 0):
Experimental. Enables a feature that causes a player who is using his ironsights
and is killed (by a gun, and not a headshot) to fire an inaccurate dying shot.

**** Karma convars:
ttt_karma (def. 0):
Enables the karma system. Players start with a certain amount of karma, and lose
it when they damage/kill "teammates" (ie. innocent if they're innocent, traitor
if traitor). The amount you lose is dependent on the karma of the person you
hurt or killed.

Lowered karma results in a damage penalty. The loss is exponential-ish, so going
from 1000->900 only reduces your damage by a percent or two, whereas a karma of
600 or so will halve your damage.

Besides the damage penalty, other players will have less incentive to hold their
fire if you have terrible karma, because it will not cost them as much karma to
kill you. The penalty is based on the victim's karma, after all. So kill a clean
player and you will get penalised a lot, but kill an overly aggressive
trigger-happy player or a griefer and your penalty will likely be much smaller.

The damage penalty is computed at the start of the round. The karma at that time
is the base karma, it's shown on the scoreboard and players have a karma status
description like "Reputable" when you target them.

During a round, as people kill each other, karma is adjusted as that happens,
but players cannot see the "live" value (because it would betray who is
innocent). The "live" karma is used in the penalty computations, so if you see a
guy kill 5 others, you can kill him knowing he is either a traitor or his karma
will be low.

See the other karma convars for more details.


ttt_karma_starting (def. 1000):
Karma players start out with. If you want players to be able to "earn" a damage
bonus, you could set this to 850 or so. Playing clean rounds will let them
increase it to a 1000 and do a few percent more damage than a new player.

ttt_karma_max (def. 1000):
Maximum karma a player can have. Note that increasing it above 1000 does not
mean players with 1100 karma will get a damage bonus. It would just give them a
"buffer" before they get a damage penalty.

ttt_karma_ratio (def. 0.001):
The ratio of the damage that is used to compute how much of the victim's karma
is subtracted from the attacker's. You can make penalties larger by slightly(!)
increasing this, to eg. 0.0015, or smaller by reducing it.

ttt_karma_kill_penalty (def. 15):
All karma penalties are based on damage dealt. The kill penalty is just an extra
amount of "damage" dealt when you kill someone. So if this was 100, and you
headshot someone with a rifle, it would penalise you as if you dealt 200 damage.

ttt_karma_round_increment (def. 5):
The base amount by which everyone's karma is "healed" at the end of every round.

ttt_karma_clean_bonus (def. 20):
If a player has not hurt or killed a teammate this round, he will be "healed" an
extra 20 karma (for a total of 25, under default settings). So if you have bad
karma it is rewarding to lie low.

ttt_karma_traitordmg_ratio (def. 0.0003):
Like ttt_karma_ratio, but for the karma reward for damaging a traitor. By
default damaging a traitor is rewarded roughly 1/4th of the penalty you'd get if
it were a full-karma innocent.

ttt_karma_traitorkill_bonus (def. 40):
Bonus karma for killing a traitor. Scaled by the traitordmg_ratio.

ttt_karma_debugspam (def. 0):
Enables debug output to console about karma changes.

**** Map-related convars:

ttt_use_weapon_spawn_scripts (def. 1):
Toggles whether weapon scripts will be used. These .txt files in the /maps/
folder can be used to override or add weapon, ammo and player spawnpoints in a
map. This is very useful for CS:S or HL2DM maps.

**** Traitor equipment credits convars:

ttt_credits_starting (def. 1):
Number of credits traitors start with. Traitors can spend credits on special
equipment.

ttt_credits_award_pct (def. 0.35):
When this percentage of the innocent players are dead, traitors are awarded more
credits.

ttt_credits_award_size (def. 1):
The number of credits awarded.

ttt_credits_award_repeat (def. 1):
Whether the credit award is handed out multiple times. if for example you set
the percentage to 0.25, and enable this, traitors will be awarded credits at 25%
killed, 50% killed, and 75% killed.

ttt_credits_detectivekill (def. 1):
Number of credits a traitor receives when he kills a detective (detective)
player.

**** Detective equipment credits convars:

ttt_det_credits_starting (def. 1):
Number of credits detective players start with.

ttt_det_credits_traitorkill (def. 1):
Number of credits detectives receive when they kill a traitor.

**** Misc. convars:

ttt_bots_are_spectators (def. 0):
Bots are spawned as spectators and will never be traitor. Useful for sourcetv.

ttt_debug_preventwin (def. 0, ie. disabled):
Prevents the round from ending, useful for testing on your own, but little 
else.

ttt_idle_limit (def. 180):
Time in seconds a player is allowed to be idle after a round has started before
he is moved to spectator.

*** Concommands:

ttt_roundrestart:
Triggers the round to restart, will go immediately to a new round in the form 
of a new preparation phase.

Requires GMod admin/superadmin status, or sv_cheats enabled.

ttt_version:
Prints current version number.

ttt_print_traitors:

ttt_dropweapon:
Will drop your current weapon. By default the key that would open the GMod
spawn menu (default: Q) instead performs this action. You can manually bind it 
to other keys using this concommand.

ttt_spectate:
Moves you onto the spectator team. You will not spawn as Terrorist until you use
"ttt_spectate 0" to turn this off again.

ttt_force_terror:
Forces you to spawn as a Terrorist. Cheat.
