Applies to:Dream Maker
Status: Open
Issue hasn't been assigned a status value.

The ability to exclude 1 or more colors from the blend process of icons -OR- the ability to split up RGB components into a list via number(or other methods to support various colors) so that I can alter the values independently.

P.S.
I'm aware that there is a version of the latter floating around the dev > lib area.

The former can be done via MapColors() or possibly SwapColor(), depending on what you want. That would be a DM language thing rather than a Dream Maker thing, though.

I think he's looking for the ability to pass a series of colors via a list to SwapColor() a bunch of colors all in one instruction moreso than apply a color matrix to the output.

I'm thinking more or less what he's trying to do is say you have a white jumpsuit with a black belt. He seems to want to be able to change the color of the belt and the jumpsuit independently.

At least that's what I got out of his request. I'm sure he could clarify it more clearly though, but I think I see what he's getting at.

Being able to do that in one shot would be helpful, to be sure, although I don't think I could justify hard-coding it. As a possible workaround, maybe this:

// colors is an associative list
// e.g.,  colors[original] = custom
#define SWAP_COLOR "#12345678"  // a color presumably no one would use
icon/proc/SwapMultiColors(list/colors)
    var/a,b
    var/list/L = new
    for(a in colors) L[a] = colors[a]  // Copy() doesn't always handle associations nicely
    while(L.len)
        a = L[L.len]; b = L[a]; --L.len
        if(a == b) continue
        if(L[b])  // if the target color is one we'll use later
            L[SWAP_COLOR] = L[b]
            L -= b
            SwapColor(b, SWAP_COLOR)
        SwapColor(a, b)
