ezQuake Manual: MVD Autotracking

MVD Autotracking

This feature allows you to sit on your lazy ass while watching a MultiView Demo (MVD) and let the client switch POVs to the best player for you. To tell the client who is THE BEST player, you have the possibility to specify an equation wich will then be evaluated for every player, giving the player a 'value'. During the playback the player with highest value will be tracked.

This value can be seen by using 'mvd_info 1' and 'mvd_info_setup %n %v' wich will show something like "Johnny_cz -6" :).

In the equation you are allowed to use the standard math operations +-/* and parentheses ().

Autotrack types

mvd_autotrack 1

This will get the current gametype and select one of the following:

mvd_autotrack_1on1
mvd_autotrack_2on2
mvd_autotrack_4on4

mvd_autotrack 2

This will use mvd_autotrack_custom

mvd_autotrack 3

Only works in combination with cl_multiview. Then you can use different equation for each window using these variables:

mvd_multitrack_1 for viewport 1
mvd_multitrack_2 for viewport 2
mvd_multitrack_3 for viewport 3
mvd_multitrack_4 for viewport 4

Constants

You can specify constants used in your equations like 'value of Quad', 'value of Pent', 'value of Nailgun' ;-).

mvd_autotrack_1on1_values for mvd_autotrack_1on1
mvd_autotrack_2on2_values for mvd_autotrack_2on2
mvd_autotrack_3on3_values for mvd_autotrack_3on3
mvd_autotrack_4on4_values for mvd_autotrack_4on4
mvd_autotrack_custom_values for mvd_autotrack_custom
mvd_multitrack_1-4_values for mvd_multitrack_1-4

All these mvd_autotrack_*_values variables consist of 14 numbers. Each number is a value assigned to given item, armor or powerup according to this table:

1	Axe
2	Shotgun
3	Supershotgun
4	Nailgun
5	Supernailgun
6	Grenadelauncher
7	Rocketlauncher
8	Lightninggun
9	Green Armor
10	Yellow Armor
11	Red Armor
12	Ring Powerup
13	Quad Powerup
14	Pent Powerup

Example:

mvd_autotrack_1on1_values "0 1 2 1 2 4 6 6 0.5 0.3 1.3 50 200 2000"

These constants are used in the %-variables. Example:

%A - armortype value: Example: you set Red Armor type value to 1.3 => %A will be 1.3 if the player has the Red Armor
%p - sum of all carried powerups values: Example: Pent Value is 2000 and Quad value is 200 => %p will return 2200 if the player has both Quad and Pent.
%w - value of the best carried weapon: The priority of the weapons is set via 'tp_weapon_order'

Variables

There are lots of variables available for you to be used with %. Most of these variables can be seen with 'mvd_status 1'.

Notes:

A run is from spawn to death.
For powerups run is from took to end/death.
An average run is a sum of all runs divided by the amount of runs.

%a	- is the current amount of armor a player has
%A	- is the value of the current armor type
%c	- current run time
%C	- current run frags
%d	- current run teamfrags
%f	- overall frags
%F	- overall teamfrags
%g	- deaths
%h	- current amount of health
%I(big i)	- taken Supershotguns
%j	- taken Nailguns
%J	- taken Supernailguns
%k	- taken Grenadelaunchers
%K	- dropped Grenadelaunchers (left in pack when player died)
%l(small L)	- taken Rocketlaunchers
%L	- dropped Rocketlaunchers
%m	- taken Lightningguns
%M	- dropped Lightningguns
%n	- taken Megahealths
%N	- taken green armors
%o	- taken yellow armors
%O	- taken red armors
%p	- added powerupvalues player currently has
%q	- Axe kills
%Q	- Shotgun kills
%r	- Supershotgun kills
%R	- Nailgun kills
%s	- Supernailgun kills
%S	- Grenadelauncher kills
%t	- Rocketlauncher kills
%T	- Lightninggun kills
%v	- average run time
%V	- average run frags
%w	- average run teamfrags
%W	- best weapon value
%x	- taken Rings
%y	- taken Quads
%z	- taken Pents

Examples

Easy one first :)

%f: This would just be the same as cl_hightrack 1

Now to make it more sophisticated:

%f/(%g+2*%F): This divides player's frags by his teamfrags * 2 + his deaths giving you some kind of efficiency calculation for the player.

For a more numbery look lets say

player 1	- 3 frags, 5 teamkills and 4 deaths (your average teamplay newbie)
player 2	- 12 frags, 1 teamkill and 2 deaths (your not so average guy with a quad run)

for player 1 it would be 3/(4+2*5) = 0.214285714
for player 2 it would be 12/(2+2*1) = 3
meaning player 2 would be tracked.

There are no limitations to how often you can use a value or how high you want to set the values or the static numbers in the algorythm. There is one limitation thats when the number is longer than 4096 digits but in that case mvd_autotrack would disable itself.
