If player has lantern

[User01]

Player gets lantern on map A. In map B an entity is supposed to be active when player has the item.

My first try (I like this better cause it seems simpler)
Map B

PHP Code: (Select All)

void OnStart()
{
AddTimer("LanternChecker", 0.1f, "haslantern");
}

void haslantern(string &in asTimer)
{
if(HasItem("Lantern"))
{
SetEntityActive("Entity_Name", true);
}
} 


My second try
Map A

PHP Code: (Select All)

void OnStart()
{
SetGlobalVarInt("LanternVar", 0);
SetEntityPlayerInteractCallback("Lantern", "Setvar", true);
}

void Setvar(string &in asEntity)
{
    AddGlobalVarInt("LanternVar", 1);
} 


Map B

PHP Code: (Select All)

void OnEnter()
{
if(GetGlobalVarInt("LanternVar")==1)
{ SetEntityActive("Entity_Name", true);
}
} 


But nothing changes when player has item.
