So I'm just having a hard time with this and hoping others on the forums can help. If I currently hold a variable that is the decimal equivalent of &hffffffff (which is white) and that decimal is 4294967295 , how wold I go about using that value in an argument that would normally accept a color represented by a hex value? Also I am declaring doubles with # so that the math goes through properly, and I even tried using the decimal directly, such as ...

`    screen.DrawObject(x, y, bm, 4294967295#)`

Am I missing something simple? How would I go about doing this?

Thank you.

I'm sure I'm missing something here, but why do you need the decimal value? Are you converting it from something else?

I'm getting the decimal value from hue,saturation,value. viewtopic.php?f=34&t=85620

I actually just figured out a slightly ridiculous way to get the result I want lol, but if it works it works. Just tried using the decTohex function found here -> viewtopic.php?t=51127

`function decToHex (dec as integer) as string   hexTab = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F"]   hex = ""   while dec > 0      hex = hexTab [dec mod 16] + hex      dec = dec / 16   end while   if hex = "" return "0" else return hexend function`

Then I took that string and put it in a

`    screen.DrawObject(x,y,bm,val(str,16))`

It worked, lol. If there is a better way I will certainly use it, but otherwise I guess this will work.

Edit: I can now change the hue and saturation of each of the 3 sections of my ship while in game... muahahaha

Sounds like you're not getting a valid value back from that function. That function returns a double, not an integer, so it won't work with DrawObject (assuming you actually mean to be passing it to DrawObject... are you trying to add a tint to the bitmap?). Have you tried casting it to an integer before returning the value?
`    color% =  rgb[0] + rgb[1] + rgb[2] + a    return color%`

I tried what you said TheEndless, the result is the same. Plus doesn't it need to be a double? If I used integers the math didn't work right. Either way, the doubles do in fact work in the DrawObject(), but at a certain point they go out of range, I believe it is 7FFFFFFF or 2147483647 that the color stops changing.

But again, it is working now, although I have to jump through a few hoops, I will jump through those hoops before the gameplay is actually going, so it's no problem.

Nope...
`BrightScript Debugger> ?type(&hffffffff)Integer`

You might need the doubles for precision during your math operations, but it should be an integer when passed to the 2D API functions. I suppose it's possible they work with either, but note that the version of Val() you used also returns an integer.
