[Proof of concept, C#] Using async for scripting in main thread

[Kryso]

So I've managed to bend async to execute code between yields in single thread and thought I'd share Similar thing can be achieved with `yield return`, but this looks quite better.

Using this concept scripts can be written like this (fake code, just an example):

private async Task KillMob(Mob mob)
{
    mob.Target();

    while (mob.Alive)
    {
        if (mob.Distance > World.Player.MeleeDistance)
            await World.Player.MoveTo(mob);

        if (!World.Player.IsAttacking(mob))
            World.Player.Attack(mob);

        Task.Yield();
    }
}

[Executable]
public async Task KillAllTheThings()
{
    Mob mob;
    while ((mob = World.Mobs.Where(m => m.Attackable).OrderBy(m => m.Distance).FirstOrDefault()) != null)
    {
        await KillMob(mob);
    }

    Script.Print("Everything is dead");
}

while running only within main thread. Njoy

This is really cool. I'd love to do something like that, but how would you handle a mob that is attacking you while approaching another mob? You don't really have a chance to account for all prioritized actions each time step if you are in the middle of a long running task. So while it makes your code dead simple and predominantly elegant, you'd be better off if you go down the behavior tree every tick.

Don't get me wrong: I really admire what you did

Wooot, Kryso. You're still in the game? I've been wondering ever since PyMode lol. Very neat stuff, been looking for a way like this forever.

[Kryso]

bananebrot: I know - my tool originally worked somewhat like that, but I like to try different things I think you could even use this within your BT to simlify some logic.. or maybe not

miceiken: Nah, I stopped playing wow when cata came. I wrote this for eve online, but the concept should be useful in any game I'm glad someone remembers PyMode tho
