var/mob/usr/M

I'm trying to use this to make an enemy look for the usr, or M.

BUT, whenever I use M in my code I get this error. Please help!

LordAndrew	`var/mob/usr/M` is a variable named `M` of type `/mob/usr`. The error means you don't actually have a type somewhere that is `/mob/usr`. Could you post the rest of the code in which that line appears in?

Linkin5622	I tyink you need to put your var in the parenthesis

Right, your error is that /mob/usr isn't a valid path in your project.

There are several ways you could handle having enemies look for players: you could either loop through mobs with clients in view or by looking for a specified type players would be (such as /mob/player).

As a side note, the spawn(src.mospeed) { Look(); sleep(10); } block will never be called (nor would you want it to, because you've already set up Look() to be a loop; calling it recursively would cause your game to stack overflow.)

This wouldn't change much, and it's perfectly fine to declare variables before using them.

Syama108	mob proc Look() var/mob/player/M while(src) if(player in oview()) walk_to(src,player,1,4) if(player in oview(1)) step_towards(src,player) else step_rand(src) break else for(player in view(src)) break sleep(1) Still didnt work.. same thing, what should I do? :(

LordAndrew	You're close! However, you named the variable `M` but you use `player` as an argument. You either need to rename `var/mob/player/M` to `var/mob/player/player` OR change all those times you used `player` as an argument to `M`.

Syama108	mob proc Look() var/mob/player/player while(src) if(player in oview()) walk_to(src,player,1,4) if(player in oview(1)) step_towards(src,player) else step_rand(src) break else for(player in view(src)) break sleep(1) I put var/mob/player/player but I still get the undefined type thing..

LordAndrew	You need to actually have the type `/mob/player` defined in your project somewhere, and your players need to be using that type for their mobs.
