Hello there :

I have problems creating acid in my position what is the error in the code or the signatures are wrong

Maybe can see this:
[L4D2] Spitter Projectile Creator

[Silvers]

Left4DHooks added this native recently to create spitter projectiles.

I understand you mean to create a spit projectile, but what I want is to create a puddle of acid in my position.

PHP Code:

GetClientAbsOrigin(client, vPos);
vPos[2] += 10.0
float vAng[3];
vAng[2] = -100.0;
int projectile = L4D_PipeBombPrj(client, vPos, vAng); 


This will create the projectile and shoot it downwards. In next Left4DHooks version (1.63) coming soon, you could specify 0 instead of client when calling L4D_PipeBombPrj.

This will create the puddle. Maybe soon I'll add natives to Left4DHooks to create fire/fireworks/explosion/acid puddle instead of creating entities/projectiles to do this. For now this will work.

hello silvers:
this function L4D_PipeBombPrj generates a pipe bomb, there is one to generate a puddle of acid

You should use left4dhooks to spawn it.

Check this plugin: https://forums.alliedmods.net/showthread.php?p=2739386
I spawn an acid inside the spitter when it dies in one of the configs.

I tried again with the code that I had put and actually if it works only that this for some reason works only when a special infected appears

[Silvers]

Ahh I meant to put "L4D2_VomitJarPrj" instead. The left4dhooks version doesn't require any special to be present afaik.
