Make a function available to any script?

Unity Engine
1

Hello,

I need to be able to access a “common” C# function from several scripts at any time. Of course I could just copy/paste said function into each script, but that doesn’t seem like an efficient thing to do (and it’s difficult to maintain, since you have to chase down every scripts where you copied it).

So what would be the best way to make a function available to any script?

Cheers,
Seith

this sounds like a job for delegates and events.

You could use a static class. Below is an example from MSDN. With this example you can call TemperatureConverter.CelsiusToFahrenheit() from anywhere.

MSDN Link

public static class TemperatureConverter
{
public static double CelsiusToFahrenheit(string temperatureCelsius)
{
// Convert argument to double for calculations.
double celsius = System.Double.Parse(temperatureCelsius);

// Convert Celsius to Fahrenheit.
double fahrenheit = (celsius * 9 / 5) + 32;

return fahrenheit;
}

public static double FahrenheitToCelsius(string temperatureFahrenheit)
{
// Convert argument to double for calculations.
double fahrenheit = System.Double.Parse(temperatureFahrenheit);

// Convert Fahrenheit to Celsius.
double celsius = (fahrenheit - 32) * 5 / 9;

return celsius;
}
}

class TestTemperatureConverter
{
static void Main()
{
System.Console.WriteLine(“Please select the convertor direction”);
System.Console.WriteLine(“1. From Celsius to Fahrenheit.”);
System.Console.WriteLine(“2. From Fahrenheit to Celsius.”);
System.Console.Write(“:”);

string selection = System.Console.ReadLine();
double F, C = 0;

switch (selection)
{
case “1”:
System.Console.Write("Please enter the Celsius temperature: ");
F = TemperatureConverter.CelsiusToFahrenheit(System.Console.ReadLine());
System.Console.WriteLine(“Temperature in Fahrenheit: {0:F2}”, F);
break;

case “2”:
System.Console.Write("Please enter the Fahrenheit temperature: ");
C = TemperatureConverter.FahrenheitToCelsius(System.Console.ReadLine());
System.Console.WriteLine(“Temperature in Celsius: {0:F2}”, C);
break;

default:
System.Console.WriteLine(“Please select a convertor.”);
break;
}
}
}

Ok, that’s great, thanks guys!
