[HELP] Script Enabling/Variables

[Cruzore]

Looking at the names of your script gives me headaches, so i'll just explain it like this:
So, you want to only put down a jar if you used the knife first.
void OnStart()
{
AddUseItemCallback("randomname1", "knife", "keg", "KnifeTheKeg", false);
AddUseItemCallback("randomname2", "jar", "keg", "JarTheKeg", false);
AddLocalVarInt("SomeVariable", 0);
}
void KnifeTheKeg(string &in asItem, string &in asEntity)
{
RemoveItem(asItem);
//fancy stuff like sounds etc here
AddLocalVarInt("SomeVariable", 1);

}
JarTheKeg(string &in asItem, string &in asEntity)
{
if(GetLocalVarInt("SomeVariable")==1)
{
RemoveItem(asItem);
//Your other stuff here, like fancy stuff and what should happen
}
}

This is just an example
