Does AGK2 have any kind of preprocessor directives features?, in other words is it possible to do different versions of code for different platforms, something like the following?...

+ Code Snippet


#If WINDOWS

function MyFunc()
Print("Windows version of function")
endfunction

#Endif



#If ANDROID

function MyFunc()
Print("Android version of function")
endfunction

#Endif

No compiler directive for that but you can use GetDeviceBaseName()

EG:

+ Code Snippet

Select GetDeviceBaseName()
	Case "windows"
		// run windows code
	EndCase
	Case "ios"
		// run ios code
	EndCase
	Case "android"
		// run android code
	EndCase
	Case "mac"
		// run mac code
	EndCase
	Case "linux"
		// run linux code
	EndCase
EndSelect

I did originally look at GetDeviceBaseName(). I was hoping for some kind of compiler directive, so that I can use one set of function names, but I guess I'm just gonna have to do it the way you show in your example.

Thanks for the advice.

Well you can have one set of function names for the main scripts just use the select statement inside your main function to trigger device dependant code.

you can use GetDeviceBaseName maybe like this

+ Code Snippet

#constant win GetDeviceBaseName()="windows"
#constant anr GetDeviceBaseName()="android"

Do

	if win
		print("windows")
	endif

	if anr
		print("android")
	endif

	sync()
	
Loop
end

You can do quite a lot with constants really. They are essentially a token:string pair that get pre-processed at compile time to inject the raw text of the string into the source code at any instance of token, meaning you can inject just about anything including more source code not just simple values.

+ Code Snippet

#CONSTANT FOREACH_Media_imageList for imageIndex = 0 to Media.imageList.length
#CONSTANT THIS_Image Media.imageList[imageIndex]

FOREACH_Media_imageList
    print( THIS_Image.fileName + " (" + Str(THIS_Image.number) + ")" )
next imageIndex

Effectively becomes on compile:

+ Code Snippet

for imageIndex = 0 to Media.imageList.length
    print( Media.imageList[imageIndex].fileName + " (" + Str(Media.imageList[imageIndex].number) + ")" )
next imageIndex

much more readable I think, and more convenient to write too

Probably not

But they worked that way in DBPro also, probably even DBClassic as well, though I don't remember for sure.
