Hi, I'm having troubles with setting some shades of colors to toggleboxes (probably even other objects)
For example, this shade of red:
Red=192. Green=0, Blue=0
- (192*65536) - (0 * 256) - (0) = -12582912
If I make a messagebox |color -12582912[ and send it to the togglebox, i get bright blue. what am I doing wrong? for most shades of colours it seems to be working OK, but not for this one and not for some others.
I don't know, but also the fact, the PD rewrites my messagebox to |color -1.25829e+007[ after save, seems suspicious to me. Is PD rounding the numbers in messageboxes? (the new form seems to be missing few digits)
please help if you can
thanks & regards,

You're supposed to also subtract 1 to the whole thing.

Yes, it is rounding numbers and this destroy part of the precision that the internal float format has. For this reason, I recompute those numbers everytime I use them, but there's another reason as well : separate r,g,b numbers is easier to understand when reading and modifying patches.
To convert values, I use the [#to_iem] abstraction : http://gridflow.ca/help/%23to_iem-help.html

I tried even that, but it was totally the same. In the meantime I found that the formula work ok if I use it directly, but when I put it in messagebox, the colour is changed.

Yes,yes. That is the problem. Thanks. Seems that I'll have to repatch all my color stuff this way. Anyway, I have to say it's kinda awful to HAVE TO do that because of this weird rounding "feature" and there are already too many workarounds in my patch. I think I'll try to count the numbers only once (on loadbang), and store them into float object that i'll bang when I need the number and don't need to recount everytime before use. (not simple thing to do, while I need this loadbang happen sooner than a loadbang that is redrawing my toggleboxes using those color numbers. Will have to switch to having only one loadbang in whole patch and "t b b b b b" after it, sending to various parts of the patch. Just because of this stupid bug). So, I think I know what I can do, to make it work... but still, I just don't get it. Shouldn't the messagebox just leave the number as is / as it would be a text? What an awful feature. There also can't be any aesthetic reason for it, while the messageboxes doesn't even show up when in GOP, which is another 'feature' of messageboxes that I fail to understand. ((not sure if worth posting in another topic, but what is the point, of having messageboxes invisible in GOP? I can move messagebox away from GOP zone if I don't want to see it.. If I have the message box it the GOP zone, then I probably want it visible to be visible, so i'm able to write in it and click it. Would be a nice addition to the small set of objects that can be used for building the GUI.
thanks and regards, Daniel
