L4D Health Bonus Update Fix 0.1.2
This plugin will fix the health bonus not updating after healing someone. Basically if A heals B, then the health bonus for A will update, but the health bonus for B will not update till someone shoots him.
Boost the Health Bonus Legitimately
There is one legitimate way to "bump" up the health bonus, basically if you have 80hp and a medkit and another person has 10hp and no health pack, then you would heal the person with 10hp. In this case it is no longer necessary to shoot the other person to get the health pack bonus to update.
Note: Originally this fixed a health bonus exploit due to pill passing or healing, but the purely exploitative part was patched by Valve in a March 11, 2009 patch.
In other words health bonuses will always update when someone is healed or pills are passed around.
This plugin will block the exploits related to the health bonus in Versus mode.
1) Passing pills around before closing the safe room door
2) Healing others with low health and then shooting them
In situation #1 the game thinks everyone has pills.
In situation #2 the game thinks the healer still has a medkit so it's the same thing as getting 2+ extra medkits at the end of a level.
Why Use The Exploit?
In both situations it is possible for the health bonus to go from 120 something to 180 and thus you get easily 60x4=240 more points (and that's just for map1), easily up to 1500 extra points overall on the campaign just from health bonus glitching.
I look forward to people picking this up until VALVe fixes it in their own patch, since currently teams glitching the health bonus virtually eliminates any point difference one might've had otherwise.
How Is The Exploit Blocked?
Whenever pills are passed to another player or someone is healed, the health bonus update algorithm gets run. We force L4D to update the health bonus for the affected players by giving them +1 temporary health (if they hadn't any temporary hp already), which almost immediately drains down to 0 temporary health.
