Reverse Friendly-Fire (l4d_reverse_ff) by Mystik Spiral
Reverse Friendly-Fire (l4d_reverse_ff) by Mystik Spiral
Purpose:
Left4Dead(2) SourceMod plugin that reverses friendly-fire...attacker takes damage, victim does not.
Objectives:
- Do not allow griefers to cause friendly-fire damage to other players.
- Incentivize all players to improve their shooting tactics and aim.
Description and options:
Reverses friendly-fire weapon damage on survivor team and claw attacks on infected team.
Does not reverse burn/blast damage, except for grenade launcher (see Suggestion section below).
Supports client language translation, currently English, French, Spanish, Russian, and Traditional Chinese.
Please note the following for the true(1) / false(0) options below:
· The victim never takes damage from the attacker.
· 1 = friendly-fire is reversed for that option and the attacker takes damage.
· 0 = friendly-fire is disabled for that option and the attacker does not take damage.
- Option to ReverseFF when attacker is an admin. [reverseff_admin (default: 0/false)]
- Option to ReverseFF when victim is a bot. [reverseff_bot (default: 0/false)]
- Option to ReverseFF when victim is incapacitated. [reverseff_incapped (default: 0/false)]
- Option to ReverseFF when attacker is incapacitated. [reverseff_attackerincapped (default: 0/false)]
- Option to ReverseFF when damage from mounted gun. [reverseff_mountedgun (default: 1/true)]
- Option to ReverseFF when damage from melee weapon. [reverseff_melee (default: 1/true)]
- Option to ReverseFF when damage from chainsaw. [reverseff_chainsaw (default: 1/true)]
- Option to ReverseFF during Smoker pull or Charger carry. [reverseff_pullcarry (default: 0/false)]
- Option to specify extra damage if attacker used explosive/incendiary ammo. [reverseff_multiplier (default: 1.125 = 12.5%)]
- Option to specify percentage of damage reversed for survivor (0=min, 2=max). [reverseff_dmgmodifier (default: 1.0=damage unmodified)]
- Option to specify percentage of damage reversed for infected (0=min, 2=max). [reverseff_dmgmodinfected (default: 1.0=damage unmodified)]
- Option to specify maximum survivor damage allowed per chapter before kick/ban (0=disable). [reverseff_survivormaxdmg (default: 200)]
- Option to specify maximum infected damage allowed per chapter before kick/ban (0=disable). [reverseff_infectedmaxdmg (default: 50)]
- Option to specify maximum tank damage allowed per chapter before kick/ban (0=disable). [reverseff_tankmaxdmg (default: 300)]
- Option to specify kick/ban duration in minutes. (0=permanent ban, -1=kick instead of ban). [reverseff_banduration (default: 10)]
- Option to specify no ReverseFF based on distance between victim and attacker (0=disable). [reverseff_proximity (default: 32)]
- Option to enable/disable plugin (0=Plugin off, 1=Plugin on) [reverseff_enable (default=1)]
- Option to enable/disable plugin by game mode. [reverseff_modes_on, reverseff_modes_off, reverseff_modes_tog]
