Attacking whats only in front of you

I have no idea where to start here except putting
mob/proc/Attack()


Could someone possibly demonstrate/guide me through the making of such proc to attack only whats in front of your mob(0 spaces away)? Maybe even show an overlay on the target?

You can use the get_step() proc to find the turf that's in front of your mob. Once you have that turf stored in a variable (let's call it T), you need to try and find something to attack in it.
// This attempts to find a /mob in the turf T. The first mob found is stored in M
var/mob/M = locate() in T
if(!M) return // Bail out if there's nothing found to attack


Once you have your /mob, /mob/monster, or whatever, you need to do the actual attacking. BYONDscape has some tutorials with basic attack procedures for causing damage, removing health, checking for death, etc.



If you want to show a targetting overlay over something, you can use image objects to do it. You'll need to create the image object, and you'll need a variable to store it in so you can easily delete it later.

mob/var
    image/targetImage
    target

// targettedMob is the "M" from earlier. This example doesn't show how to get it
mob/proc/Attack()
    if(target != targettedMob) // If the mob being attacked has changed
        target = targettedMob
        del(targetImage) // Delete the old targetting overlay
        targetImage = image('target.dmi', targettedMob)
        // This creates an image from target.dmi which is placed on top of targettedMob
        src << targetImage // Non-overlay images need to be specifically
                           // outputted to players
    // Actual attacking goes here


That's an example of one (possibly buggy) way to show a targetting overlay over what you're attacking. It has some problems such as the overlay will stay on a mob until you attack another one. So a player could possibly run away from a battle, and come back later and see his targetting overlay on top of what he was attacking a while earlier.
