/turf is turning black!

        var
            turf/pxlboard/pxlboard = locate(ceil(x, 4) / 4, ceil(y, 4) / 4, z)
            icon/pxl = icon('pixel board.dmi', state)
        pxl.Shift(1, ((x - 1) * 8))
        pxl.Shift(2, ((y - 1) * 8))
        pxlboard.icon = pxl.Blend(pxlboard.icon)


Am I in some way not using the Blend proc correctly or something? I've checked the pxl icon and it's as it should be, and so is pxlboards, yet when I blend them there, the whole thing turns black!

What's going on with it?

Just to be sure of something, do you have world.turf set anywhere? It could be a problem elsewhere, where you are maybe relocating or deleting the turf, and as a result, the location turns to a default world.turf of /turf.

[Edit]
Also, by any chance, does pxlboard even have an icon?

Nope, it's not set. I set it just to see what would happen, though, same effect.

Maybe if I used /obj instead?

Is variable state a valid icon_state? Have you tried using pxlboard.icon = pxlboard.icon.Blend(pxl)? Note, to do that, you probably need to do something like:

var/icon/pxlbicon = icon(pxlboard.icon,pxlboard.icon_state)


And instead of pxlboard.icon = pxlboard.icon.Blend(pxl), use pxlboard.icon = pxlbicon.Blend(pxl). I dunno, I usually try differing variations of a bunch of things if I can't figure out the problem.

Okay fixed it.

Well, what was the problem?

I wasn't shifting in the right direction, I was using the wrong blending operation, and other various things that I've already forgotten due to severe lack of sleep.

It immediately looked to me like this was the culprit: 
 pxlboard.icon = pxl.Blend(pxlboard.icon)


I don't think you can do that - AFAIK, icon.Blend() doesn't return a value (returns null) - it only changes the icon it's used on. Therefore, you needed to do this instead: 
pxl.Blend(pxlboard.icon)
pxlboard.icon = pxl

Yeah. I realized that shortly after I posted my last message here.
