I was trying to allow a player to modify the colouring of the text displayed by my program by letting them edit an .ini file. Now the .ini file works flawlessly. It stores and reads the data correctly.

My problem is that when I use the following code (Shortened to show the problem)

+ Code Snippet

 #CONSTANT clrWhite                 RGB(255,255,255)
 #CONSTANT clrBlack                 RGB(0,0,0)

 `ini reading here, these lines work flawlessly, tested to death
 `shown here for the purposes of showing how the variable is loaded
 backColour$ = ReadIniString(  "Colour", "backColour" )
 textColour$ = ReadIniString(  "Colour", "textColour" )

 ink textColour$,backColour$

I get the following error "Parameter for 'INK' do not match 'Foreground Colour,Background Colour'." I know it's because of the fact INK doesn't seem to like using a variable (string) value that is a constant. At least that's what it seems. I've tried using a integer value without the RGB section within the Constant and that simply dint work at all. So I'm at a loss. Where am I going wrong? Is what I'm trying even possible with the method I've chosen?

Because the Ink command needs DWORDs instead of strings.

If the file contains the DWORD values, then this would work...

+ Code Snippet

ink val(textColour$),val(backColour$)

If the file contains strings like "rgb(255,255,255)" or number values like 255,255,255 then you will have to calculate the DWORD value for the constants. Post an example of what's inside the ini file, so we can see what is needed.

This is the ini contents. I had a feeling I was going the wrong way about it.

+ Code Snippet

[Display]
iscrWidth=800
iscrHeight=600
iscrDepth=16

[Colour]
sbackColour=clrWhite
stextColour=clrBlack

Not so! You just have to write the code to interpret the ini values into the correct color values for your program.

You could use if/then statements to find the color, or select case, or put the values in an array, lots of options. Shouldn't be too hard to code at all!

It would be easier to let the user totally decide which red, green, blue content for each color rather than set constants that have to be in your code.

+ Code Snippet

[Display]
iscrWidth=800
iscrHeight=600
iscrDepth=16

[Colour]
sbackColour=255,255,255
stextColour=0,0,0

A suggestion: Why not just declare the colors as global variables?

+ Code Snippet

global white    : white = rgb(255,255,255)
global black    : black = rgb(0,0,0)


repeat
  ink white,black
  set text transparent
  text 100,100,"Here is what white/black looks like."
  ink black,white
  set text opaque
  text 100,200,"Here is what black/white looks like."
until scancode() > 0
end

So many games to code.......so little time.

You cant translate strings into variable names in DBP (it'd be really cool if you could though!)

Anyway this:

+ Code Snippet

Black=0
Blue=rgb(0,0,255)
White=rgb(255,255,255)

ColorVariable$="Blue"

ink ColorVariable$,0

will not work. You have to do something like this:

+ Code Snippet

Black=0
Blue=rgb(0,0,255)
White=rgb(255,255,255)

ColorVariable$="Blue"

if ColorVariable$="Blue"
     ink Blue,0
endif

if ColorVariable$="White"
     ink White,0
endif

if ColorVariable$="Black"
     ink Black,0
endif

or maybe even this:

+ Code Snippet

Black=0
Blue=rgb(0,0,255)
White=rgb(255,255,255)

ColorVariable$="Blue"

if ColorVariable$="Blue"
     Color=Blue
endif

if ColorVariable$="White"
     Color=White
endif

if ColorVariable$="Black"
     Color=Black
endif

ink Color,0

Guns, cinematics, stealth, items and more!
