How to calculate RGB coefficient?

[Outcast]

Is there any way to calculate the rgp coefficient you need to change the color of a object to another or do you just have to guess?

For example I have smoke in my game that is brown, but want to add an event to add the event: Set RGB coefficient, so the brown object gets more white to look like white smoke instead of brown. From what I understand I should put in numbers like 124,253,111 in the RGB coefficient window for the event? But how do I know what value to put in to make one color into another?

The reason I want to use this method to change color is because I want it to be compitable with Flash. I dont know if there is any other effects or shaders that are supported by flash yet besides this?

Have you used the GetRGB() function (in the system object's expressions)?

Hmm I dont know if I tried that, but won´t that just give me the objects current RGB value? How do I use that after I know what it is to get the right color I want?

You probably mean RGBAt. Just use GetRGB(r,g,b) like the documentation tells you. GetRGB(255, 0, 0) returns red.

OK, I tried the GetRGB function, and it seems to works for all colors except the one I need which is White :/. Black works by giving the value 0,0,0. But when I tried 255,255,255 to get white nothing changes?

Huh? The default is white, and a color multiplied by white is the same color.

This is one reason *my* application cannot use RGB Coefficients

Every element in my application starts out, by default, in one certain color (values range from 0 to 9, starting at 5 with each change adding 25 to, or subtracting 25 from, a color) and you must remove or add color in red, green, or blue to change to a desired color.

Since the default coefficient, white (255, 255, 255) is the color you start out with, it is impossible to add anymore color (which elements must be able to do) using the RGB Coefficient method. If I use a mask over top of the default sprite it can use the coefficient method just right...but does not produce ANY of the correct colors I need...therefore I had to resort to using red-, green-, and blue-colored masks and individually change their color intensities separately...it's quite the tedious hassle, time consuming, and bogs down the runtime..

I would actually give anything to be able to reduce the number of objects in my application if I could use one single mask instead of 15 masks stacked onto an individual sprite...but the colors I need are simply not produced by the use of coefficients.

A bit of another question. Its really strange, i noticed that when i try to change the rgb coefficient in the frame editor right in the properties bar i can no longer see any effect on the object. It do chage color as soon as I try to run the frame though. Is this a new bug in 254 maybe? I just updated and i could always see rgb coefficient effect directly on object i adjusted in frame editor before.
