game_scavenge_progress_display is a point entity available in 
Left 4 Dead 2. When turned on it displays the number of gas cans poured into point_prop_use_target entities in the current round on the upper part of the screen as <number_of_cans_filled> / <Max>. Number of filled cans cannot be decreased using available inputs but it's possible with vscripts. Turning it off and back on won't nullify the amount.
Keyvalues
- Name
(targetname)<string> - The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g.
parentnameortarget).
Also displayed in Hammer's 2D views and Entity Report.See also: Generic Keyvalues, Inputs and Outputs available to all entities
- Max
(Max)<integer> - Number of items to collect.
Inputs
TurnOn- Turn the display on.
TurnOff- Turn the display off.
SetTotalItems<integer>- Set the target (or total) number of scavenge items.
Vscript Enhancement
Script example to increment/decrement or reset the counter. When this script is used as this entity's Entity script it sets FireUser1 input to increment the counter, FireUser2 to decrement the counter and FireUser3 to reset the counter to 0.
Todo: should work in versus and coop gamemodes but needs more testing
