Adding static functions
Alright I guess this is more of a general programming question, but here goes; I want to make my function / script always active without it being added to the scene. I have a few different functions I use in many different scripts. Adding the script to the scene and pointing to it from the other scripts is a troublesome process. Is it a good practice to make such function static? Is there another way out?
This is one of the functions I use a lot
//Gets the vector3 from a string
public Vector3 getVector3(string rString){
string[] temp = rString.Substring(1,rString.Length-2).Split(',');
float x = float.Parse(temp[0]);
float y = float.Parse(temp[1]);
float z = float.Parse(temp[2]);
Vector3 rValue = new Vector3(x,y,z);
return rValue;
}
This is the script I've made with the function(s)
using UnityEngine;
using System.Collections;
public static class MyFunctions {
public static Vector3 getVector3(string rString){
string[] temp = rString.Substring(1,rString.Length-2).Split(',');
float x = float.Parse(temp[0]);
float y = float.Parse(temp[1]);
float z = float.Parse(temp[2]);
Vector3 rValue = new Vector3(x,y,z);
return rValue;
}
}
You are right this is more like a general programming question. Of course you can create static class with static value and static functions or a classic class but with static method and classic method.
It's up to you, it could be useful if you work in a team and create static functions accessible for other developers. It's also useful because using gameobjects in the scene consumes resources and affect performances and if you can use a static class with static functions why not doing it :) it will save ressources.
A great example is the Mathf class in Unity, there's no advantage of create a classic class, just do a static class and here we go.
Here is an interesting question asked on StackOverflow : Performance of static methods vs instance methods
Another option would be the singleton pattern.

Also if you don't want to to place your script in the scene at all, you can define a class that is not inheriting from MonoDevelop.
Of course, it depends of the usage. It's more related to pattern program$$anonymous$$g. A Singleton Pattern is adapted to manager classes for example.
