//To be exact, i dont kno exactly how i am gonna make an afterimage effect
//I got the idea after i made a character for M.U.G.E.N



/*
A quick introduction on how im gonna do this
I am gonna make an afterimage effect as you kno
But i dont kno how to do this, so im asking for help here

My first attempt was to create a loop that creates an obj for every afterimage amount
And place them between the first afterimage and the main thing or obj

but i didnt kno how to do that

my second atempt i tried to create a proc that runs everytime you move and creates an obj in
the same place as the obj but it didnt work out great


*/
mob/proc
    Afterimage(r,g,b,mob/what,amount) //this is what i got so far
        if(amount > 32) amount = 32 //if the amount ever surpassed 32 afterimages for what ever reason, put it back to 32
        var/placement = 32/amount
        if(what.dir == WEST)
            for(var/i , placement < i , i++)
                var/obj/M = new what
                M += rgb(r/256,g/256,b/256)
                M.pixel_x += what.x - 32 + (32/placement/2)


    Afterimage_Handler(mob/T) //something to generate the after image
    //Hmm, i wish i could create an something with a specific frame within an icon. Might as well request it.
    //Might be better, for a smoother afterimage effect
        var/obj/newMob = new /obj(T.loc)
        newMob.icon=T.icon
        newMob.overlays=T.overlays
        newMob.density=0
        newMob.dir=T.dir
        spawn(15)
            del newMob


Im trying to make an afterimage effect, which saves a icon and adds rgb and places it some amount of pixels away from an object that wants an afterimage, then deletes it after a certain amount of time. Soemthing like this is in Street Fighter Games and such.

You're going to have to actually tell us what you're trying to do, here.

its commented in the code

But anyways, im trying to make an afterimage effect, which saves a icon and adds rgb and places it some amount of pixels away from an object that wants an afterimage, then deletes it after a certain amount of time. Soemthing like this is in Street Fighter Games and such.

Sorry, but "I am gonna make an afterimage effect as you kno" is not an adequate description of what you are trying to do.

Max i was gonna use a simular function in my game. i think as of right now, the only way to do this is like this.
var/obj/o=new obj(src.loc)
flick(o,o.loc)
for(var/xx,xx<5,xx++)
   spawn(xx)o.icon+=rgb(0,0,0,5*xx)
   spawn(xx)flick(o,o.loc)

Im gonna go out and try this. Have you tested this way before? and would it be good if i made it so it had the same direction as the obj?

After-image

After-image \Aft"er-im`age\, n. The impression of a vivid sensation retained by the retina of the eye after the cause has been removed; also extended to impressions left of tones, smells, etc.

I thought he explained it just fine, actually. :P

proc/afterImage(mob/targetMob,delay=50,color=rgb(0,0,155))
    var/mob/afterImage = new
    afterImage.dir = targetMob.dir
    afterImage.icon = targetMob.icon
    afterImage.icon_state = targetMob.icon_state
    afterImage.icon += color
        afterImage.loc=targetMob.loc
    spawn(delay) del(afterImage)


You could do something like that. You could also use an object instead of a mob for the afterImage variable, in case you don't want the after-image to be able to interact with players (being attackable, for instance). I'm not sure if you can use the rgb() proc in the manner I did (I think I've done it before, but I can't remember offhand), but it should work. If not, it shouldn't be hard to remedy.
