NPCS that shoot projectiles

How would I do this? I can see making the mob shooting a projectile once, but how do I get it to loop while the player is in front of it or behind it?

I won't program it I'll say it.

If the players (P) is in src's oview (make sure you check that), then if P is get_dist (a certain distance away), you'll shoot the blast every, say, 1 to 5 seconds, you choose.
*DM*

There is probably a better way. But I hope this helps you figure out how to program an NPC shooting projectiles at a player.

In response to A. Ness
Ness that cycles through everyone in view, not a particular direction. To get only mobs above or below, I think you'd have to do something like this:

mob/NPC/proc/Look_Around()

    if(target)  // If the NPC has a target
        return      // stop the proc

    for(var/mob/M in view())
        if(M.y == src.y && get_dist(src, M) < 6)     //you can add "&& M.x == src.x" if you sideways shooting as well
        // If the "Up" and "Down" of the mob in view is equal to the NPC's Up and Down.
        // And if the distance between the NPC and the mob in view is under 6 tiles

            target = M      // You target the mob

            src.dir = get_dir(src, target)  // NPC faces the mob which is now the target.

            AI_Fire()   // This proc is where you do your snazzy projectile stuff.


I spaced it out so it wouldn't look so cluttered.

This doesn't give you the perfect AI code, but shows you how to do what your trying to do.

Learn get_step and get_dist from "Help On..." under the Help tag in Dream Maker. I tried to explain it so you'd understand what everything does. Correct me if I'm wrong about anything Byondlings.
