Oh man....

[DamnNoHtml]

void AddEnemyPatrolNode(Monster1, PathNodeArea_35, 3, string& asAnimation);

void MonsterWalk1(string &in asParent , string &in asChild , int alState)
{
SetEntityActive("Monster1" , true);
}

Remove both of the

void AddEnemyPatrolNode(Monster1, PathNodeArea_35, 3, string& asAnimation);

Maybe change it to

void MonsterWalk1(string &in asParent , string &in asChild , int alState)
{
SetEntityActive("Monster1" , true);
AddEnemyPatrolNode("Monster1", "PathNodeArea_35", 3, "");
}

I changed it and now have this:

Code: (Select All)

////////////////////////////
// Run first time starting map
void OnStart()
{
AddEntityCollideCallback("Player" , "Monster_Walk_Trigger" , "MonsterWalk1" , true , 1);
AddEntityCollideCallback("Player" , "Monster_Walk_Trigger" , "AddEnemyPatrolNode" , true , 1);
}

void MonsterWalk1(string &in asParent , string &in asChild , int alState)
{
SetEntityActive("Monster1" , true);
AddEnemyPatrolNode("Monster1", "PathNodeArea_35", 3, "");
}

////////////////////////////
// Run when entering map
void OnEnter()
{

}

////////////////////////////
// Run when leaving map
void OnLeave()
{

}

The monster doesn't spawn when I walk to where I placed the script though (it doesn't ever spawn).

There is no problem with your code. Make sure the Script Area / Monster names all match up exactly. Its one of the more common mistakes.
