Getting Started

Hello everyone!
Before I used GameMaker and there I could create a script with some common functions and after using it with different objects (for example write function of damage and use it for player and for enemy). Now I want to do something like this in Unity, but I really don’t understand how, because

  1. Maybe I am wrong, but I suppose that I can use scrit if it is attached to an object
    then I decided to attach to GameManager object, but
  2. if I want to use the method in my Player script, I have to create a variable, find object GameManager, get component(script) of the object and only after that I can use this method
    But it looks very complicated for this purpose. Maybe there are some simpler way to do this? I tried to find the answer by myself but I failed

If you want a class that just contains helper functions, make it a static class.

public static class MyHelperClass
{
	public static void MyHelperMethod() { ... }
}

// usage
MyHelperClass.MyHelperMethod();

Ideally you name the class something relevant to the methods you’re going to put into it.

Thak you very much! And attach it to Game Manager object (for example)?

It’s a static class, ergo it can’t be instanced. You don’t need to attach it to anything.

Only your custom classes derived from MonoBehaviour need to be attached to game objects.
