Get the number of false bools in GameObject[] (array)

Questions & Answers

Hey Unity Pros,

So this has been my nightmare for the last couple of hours trying to get this working. Basically, I want to get the number of false booleans in an array of GameObjects and simply display it as an int value. I dont know if this thing is too complicated and beyond my coding skills(which is pretty low btw) or Im just too dumb for this sh*t lol.

Anyway, Id really appreciate it if someone could help me!

Thanks in advance.

UPDATE: I have added a sample script to roughly visualize what i was trying to explain above.

void Update () {

		bulletCounter.text = "BULLETS: " + //plus the number of bullets that hasnt been fired yet

// i tried with for loop but it gave me the name of the GameObject instead of the total number of not fired bullets

		for (int i = 1; i < projectiles.Length; i++) {

			if (projectiles *.GetComponent<Projectile> ().hasBeenFired == false) {*

_ bulletCounter.text = "BULLETS: " + projectiles*.ToString();_
_ return;_
_ }_
_ }*_

Hi yapaysinek,

The best way to approach this is to have an integer which you increment every time you find a boolean which is false.

I noticed in your original code you had for (int i = 1; i < projectiles.Length; i++) {. If you want to loop through every element in the array you should set i = 0 as arrays start at 0, not 1.

See the below code for my solution to your problem:

	void Update () {

		// The number of false booleans in our array
		int numberOfFalseBooleans = 0;

		// Loop through every array element
		for (int i = 0; i < projectiles.Length; i++) {
			// We check each array element one at a time
			// We are checking if this projectile hasBeenFired is equal to false
			if (projectiles *.GetComponent<Projectile> ().hasBeenFired == false) {*

  •  		// If it is equal to false, add one to our numberOfFalseBooleans counter*

  •  		numberOfFalseBooleans++;*

  •  	}*

  •  }*

  •  // Finally, display the number of false booleans*

  •  bulletCounter.text = "BULLETS: " + numberOfFalseBooleans;*

  • }*
    Hope this helps!

There’s a couple ways to do this. If I understood this right, one way would be to have an int variable that stores the projectile array’s length and drop it’s value accordingly:

int projectileAmount = projectiles.Length;

for (int i = 0; i < projectiles.Length; i++) {
   if (projectiles *.GetComponent<Projectile>().hasBeenFired == true) {*

int projectileAmount -= 1;
}
}

bulletCounter.text = "BULLETS: " + projectileAmount;
Note that I am modifying the text after the loop.
Now, I don’t know your particular setup, but for this problem alone this should work well enough.
EDIT: I had forgot to edit the boolean value to true, sorry. What I am essentially doing here is checking how many bullets you have left after firing them and then printing that out. If that is not what you wanted, Pzula’s answer has a correct way of checking the number of false booleans in your array which is what you were originally asking. Sorry for misreading there.

Hey! You can loop through your array length and access whatever you want!)

For(int i = 1; i<YouArrayName.Length;i++)
{
  // get ur false bool here

         if (YouArrayName*)*

{
return YouArrayName*;*
}
}
}
This will give you the true booleans. So now you can now how many false or true you got
