About:

• Unlocks the Spitter Acid to detonate various explosives.
• Unlocks the Spitter Acid to damage common and special infected.
• The games default behaviour alternates between 0.2 and 0.3 seconds to damage entities.
• The game scales damage over the duration of effect: 0 at the start, 6 in the middle and 4 when it ends.
• This plugin can scale that damage where 1.0 is default, or set a full value to damage each time (this plugins default for common and special infected).
• Also included in the source for developers a demonstration on "inferno" entities and getting their flame positions.

Thanks:

• Iizuka07 - For the idea and request.
• Lux - For scripting advice.

Now this will do some damage

[paul92]

Genious! You strike again Silver! Will try it soon

[Silvers]

Suprised no one complained about Linux crashing, or some cvars broken, or the fact Spitters killed themselves standing in their own spit lol. Well all that's fixed.

    - Fixed cvar "l4d2_spitter_acid_damage" not actually being used.

    - Added cvar "l4d2_spitter_acid_explosives" to allow Spitter Acid to ignite/explode explosives.

PHP Code:

l4d2_spitter_acid_explosives "3"        // Allow acid to ignite explosives: 0=Off, 1=GasCans, 2=Firework Crates, 4=Oxygen Tank, 8=Propane Tank, 15=All. Add numbers together. 


Can't believe I didn't add this from initial release. Something I wanted to replicate for years.

[KoMiKoZa]

Thank you for this great plugin, greatly enhances spitter's value!

I'm having an issues however of the gascans not being burnt by spit. And seemingly that's only gascans, propane tanks actually explode (and instadamage application works). Could you test that on your end? Seems weird, don't think anything on my server (Linux/SM 1.10) interferes with gascans/spit.

And yes, I've got the explosions set to All, which is supposed to cover gascans.

[Silvers]

Thanks, fixed:
