dictionary of functions?

Questions & Answers
1

In c# this works:

Dictionary<int, System.Action> functions = new Dictionary<int, System.Action>();

I’m using System.Action because my functions return nothing and take no parameters

void Function1()
{
    Debug.Log("This is Function1.");
}
//add a function to the dictionary with key 1
functions.Add(1, Function1);

//call it
functions[1]();


//    console output:
//"This is Function1."

However, in a unity c# script I’m getting an invalidkey error. What am I doing wrong?

EDIT: I figured out what was wrong with my code. I’m using a getter and setter, and in the set block I wasn’t setting the variable to the keyword “value”

private int _funcNum
public int functionNumber
{
    get
    {
        return _funcNum;
    }
    set
    {
        _funcNum = functionNumber; //This should be: _funcNum = value;
        DoFunction(_funcNum);
    }
}

really not sure why it’s not working for you - i tried the following and got the expected results (including the error for the entry which didn’t exist)

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class ActionTest : MonoBehaviour
{
	Dictionary<int, System.Action> functions = new Dictionary<int, System.Action>();

	void Start()
	{
		functions.Add(64, Function0);
		functions.Add(57, Function1);

		functions[57]();
		functions[64]();
		functions[3]();
	}

	private void Function0()
	{
		Debug.Log("Function 0");
	}

	private void Function1()
	{
		Debug.Log("Function 1");
	}
}

in future, please also include the complete error message.
