Question

I'm just about finished on a 2D shooter game and everything is working perfectly except for my score multiplier power up. I know the bool value is being set to true when the player picks it up but when I kill an enemy the value is false...not sure what's going on

here's my code for the power up

 private GameObject objPlayer;  private AIscript scriptAI;

// Use this for initialization
void Start () {
    objPlayer = (GameObject) GameObject.FindWithTag("Player");
    scriptAI = (AIscript) objPlayer.GetComponent(typeof(AIscript));
}

void removeMe ()
{
    Destroy(gameObject);
}

void OnTriggerEnter (Collider Other)
{
    if (Other.gameObject.tag == "Player") //only player can trigger powerups
    {
       scriptAI.isMult = true;
       Debug.Log("multi picked up!!");
       removeMe();
    }
}

and where the value is used in the character script

 //boolean vars for power ups  public bool isLaser;  public bool isSpread;  public bool isMult;  private float powUpTime; //local timer variable for laser and spread power ups  private float powUpTime2; //local timer variable for score multiplier power up  private float powUpLength = 10f;



void Start () {
		powUpTime = powUpLength;
		powUpTime2 = powUpLength;
		isLaser = false;
		isSpread = false;
		isMult = false;
	}

void Update () {
		//check for newly acquired power up and start timer
		if (isLaser || isSpread)
		{
			powUpTime -= Time.deltaTime;
			if (powUpTime



void removeMe () //removes character
	{
		if (thisIsPlayer == false)
		{
			Instantiate(ptrScriptVariable.parAlienDeath, transform.position, Quaternion.identity);
			GUIvarScript ptrScriptGUIvar = (GUIvarScript) objPlayerStats.GetComponent(typeof(GUIvarScript));
			ptrScriptGUIvar.enemiesKilled += 1;
			//check for multiplier power up
			if(isMult)
			{
				Debug.Log("multi!!");
				ptrScriptGUIvar.score += 20;
			} else {
				Debug.Log("no multi!!!");
				ptrScriptGUIvar.score += 10;
			}
		} else {
			Instantiate(ptrScriptVariable.parHumanDeath, transform.position, Quaternion.identity);
		}
		Destroy(gameObject);
	}
i'm not sure how I could be losing the value because the logic seems right to me but I am fairly new to unity and C# so who knows

When the player picks up a multiplier, it sets isMulti = true in the player's instance of AIScript. When the enemies die, they check if isMulti is true in their own instance. When they die, they need to check the instance on the player.

removeMe() is a function in AIscript that gets called from Update if the health of either the enemy or the player is <= 0. sorry if this was unclear, I removed parts of the code to keep it less cumbersome

I was always curious how variables were called when one can attach an object to the Inspector view. So it is simply called "ScriptName" object be it a variable or another object?

Thanks CSDG

I think I got it. Take a look at the edited answer.

got it! used a pointer to the player's instance of AIscript and it's working now. Thanks for the help, the instance stuff has been the hardest thing for me to grasp

Excellent! If this answer helped, you should "accept" it as the correct answer. Just click the little checkmark by the thumbs.
