[SCRIPT] why wont this work?

[oscar1007]

So, the player har a jar in his inventory, now when he uses that on a body part of a dead grunt, i want the player to get a different jar (filled with blood). This is my script:


void OnStart()
{
AddUseItemCallback("", "hollow_needle_1", "grunt_body_part2_1", "take_blood", true);
}


void take_blood(string &in asItem, string &in asEntity)
{
GiveSanityBoostSmall();
RemoveItem("glass_container_1");
GiveItem("", "glass_container_blood_1", "glass_container_blood_1", "glass_container_blood_1.tga", 1.0f);
}


The "glass_container_blood_1" is in the map, i just placed it so the player cant get it.

And, when i try to use the jar in game, nothing happens. It says cant use item this way or something.

Why wont this script work?

Thanks!
