Enemy spawning at an area

[xtron]

Spoiler below!

void OnStart()
{
AddEntityCollideCallback("Player" , "lurkerspawn" , "spawn_water_lurker" , true , 1);
}

void spawn_water_lurker(string &in asEntity)
{
SetEntityActive("rawr", true);
StartPlayerLookAt("rawr", 10, 50, "");
AddTimer("", 0.5f, "TimerSlamDoor");
}

void TimerSlamDoor(string &in asTimer)
{
PlaySoundAtEntity("", "react_breath_slow.snt", "Player", 0, false);
AddTimer("", 1.0f, "TimerStopLook");
}

void TimerStopLook(string &in asTimer)
{
StopPlayerLookAt();
}

Now. When you enter the "lurkerspawn" area the function "spawn_water_lurker" will get activated and a breathing sound will be played and the lurker named "rawr" will spawn and then your screen will automaticly move and look at "rawr" for 1sec then return to normal.
