[Solved]Two Player Error

Questions & Answers
1

So I have made this really simple player script, which gets its controls from a Hashtable I have set up in a different script. The player always moves to the right and the controls will make it change direction. I have set up 4 different control schemes for 4 different players. When I only have 1 player in the scene it works fine, I can assign the player a player number and the control scheme changes depending on player number. Everything works perfectly. However when I duplicate the player and give them 2 different player numbers, the duplicated player will not move or react to controls.

I get these errors when duplicating the player and starting the game

The 1 and 2 are a Debug.Log I put in to check that they are reciving their playernumbers correctly. However player number 2 gets a NullReference

This is the initialization code that gets executed, this is where I fetch the controls in the main Player.cs.

void Start () {
    rigidbody = GetComponent<Rigidbody2D> ();
    controls = GetComponent<PlayerControls> ();

    //GET CONTROLLERS
    Debug.Log(playerNum);
    control = controls.getControls(playerNum);
    setKeys(control);
}

and here is how the PlayerControls.cs looks like.

void Start () {

    //Player1
    player1 = new Hashtable();
    player1.Add("Up", "a");
    player1.Add("Down", "d");
    player1.Add("Shoot", "s");
    player1.Add("Boost", "w");

    //Player2
    ....
    ....
}

public Hashtable getControls(int num) {
    if(num == 1) {
        return player1;
    } else if(num == 2) {
        return player2;
    } else if(num == 3) {
        return player3;
    } else if(num == 4) {
        return player4;
    } else {
        Debug.Log("Incorrect player number!");
        return new Hashtable();
    }
}

Looks like it isn’t sending a Hashtable in the setKeys() call.

Try putting a check around it like this:

if(control!=null){
	setKeys(control);
} else {
	Debug.Log("No Control");
}

And see what comes out?
