SOLVED number of arguements in a script "error"

[robertleva]

/// @desc approach (min, max, inc);
/// @param min;
/// @param max;
/// @param inc;

function approach(){
if (argument0 < argument1) return min(argument0 + argument2, argument1);
return max(argument0 - argument2, argument1);
}

Can anyone tell me why Gamemaker gives me a little yellow warning sign saying "number of arguments expected 0, got 3"?

The script works fine but the little warning icons are annoying.

Why not provide the arguments in the function declaration instead of using the old-fashioned argumentN version? Ideally using names that don't clash with built-in names, of course.

See: IMPORTANT!!! GM 2.3 Users Please Read! Improper script usage generates undefined variable errors (Examples of Converted Script Functions > Fixed number of arguments)

/// @desc approach (min, max, inc);
/// @param min
/// @param max
/// @param inc
function approach(_min, _max, _inc) {
    return (_min < _max) ? min(_min+_inc, _max) : max(_min-_inc, _max);
}
