64Digits

Today I started on something I've been avoidng: Npcs. They are probably one of the biggest parts of the game and require the most code (in my opinion). So far I having been working on what actions they can do: moving, stabbing, shooting. I also have started to work on the pathfinding system. So far my Npc is running back and forth in a straight line.

You cannot see it but he is running back and forth non-stop

I have also added the code that can change clothes! Why? Because green is fashionable!

Green FTW!

Also I'm going to be making different armours for the defence stat.

I posted an example on randomly moving NPCs back in '07. If anything, you should check it out. My logic style has changed a great deal from then, but it may prove useful to you.

This is the kind of thing I use for wandering

{
if round(random(100)) = 1{
            direction = round(random(3))*90;
            speed = 2;
            }
else
if round(random(80)) = 1{
            speed = 0;
            }
}

(Sorry if that doesn't make sense, I don't usually use GML)

Pathfinding, however, is a completely different story.

For a top-down game like this, you could use AI nodes.

Green is win.

With that code, your NPCs could potentially just walk in one direction forever… never to be seen again.

I actually won't be using random wandering in this game. Most of the NPCs will have a predetermined path.

Just be sure to have them check if their pathing location is not blocked. Can't tell you how many times a static npc has broken my movement logic with its automatic static pathing.

Step Event:
image_angle = random(360);

Done. It's perfect.
