Been doing this for a while, and thought that maybe it'd be handy for any newbies... If you're calling a function that will use different colours, you may want to return to the set colour that you were using before you called the function. Easy enough... Here's what you'd do if you want to stick it in your own function... Function my_function(blah,blahdefault=1) Local red=ColorRed() Local green=ColorGreen() Local blue=ColorBlue() ; Do function stuff here Color(red,green,blue) End Function --v Here's the thing using another method... global red,green,blue Function my_function(blah,blahdefault=1) SaveColorSet() ; Do function stuff here LoadColorSet() End Function ;Color memory functions... Function SaveColorSet() red=ColorRed() green=ColorGreen() blue=ColorBlue() End Function Function LoadColorSet() Color(red,green,blue) End Function --v The advantage of that last one is that you can do it mid-program too... color(Any_Colour_That_Could_Chnage) ;Do Stuff SaveColorSet() color(Any_Colour_That_Could_Chnage) ;Do Stuff color(Any_Color_That_Could_Chnage) ;Do Stuff LoadColorSet() ;Do Stuff --v Which would be handy in a few circumstances, although you may be storing the colours as variables anyway for that scenario.
