DisplayAtY question

[CaptainD]

Is it not possible to put a variable into a DisplayAtY expression?

Code: ags

DisplayAtY(200, "Cats are on the prowl... they manage to kill %d of your rats", num)

returns the error wrong number of parameters in call to 'DisplayAtY' - it works fine with Display but I want to position the text displayed.  Am I missing something obvious or is it simply a limitation of this particular function?  I can't find anything explicit in the manual about this.

Only functions that have "..." in the parameter list may take extra variables to format a string. This is called "variadic function".

Compare:

Code: ags

Display (string message, ...)
DisplayAt(int x, int y, int width, string message, ...)

But

Code: ags

DisplayAtY(int y, string message)

When you need to pass a string somewhere that does not have "...", use String.Format to create a string:

Code: ags

DisplayAtY(200, String.Format("Cats are on the prowl... they manage to kill %d of your rats", num));
