Hallo,

public float count;

count = 3;

SetCountText();

void SetCountText()
{
	countText.text="Count: "+ count;

and in the text its display 3 thats fine.

but i need to have an array so i try it with an array

public float count;

count[0] = 3;

SetCountText();

void SetCountText()
{
	countText.text="Count: "+ count[0];

and notthing happend, on the display they are written Text and not the number.

i try it with public float count = new float[6]; and it doesnt work.

Try this and post what you find out.

void SetCountText()
 {
Debug.Log(count[0]+""); // to ensure the variable has a value
int C = count[0]; 
countText.text="Count: "+ C;

this is just to test where the error is, you should be able to pass a value inside of an array with no problem.

Hallo
Thanks for your answer,
i try it but it doesnt help.

i get in the Error
IndexOutOfRangeException: Array index is out of range.

public class PlayerController : MonoBehaviour {

public Text countText;

public float [] count;

void Start ()
{

	count[0] = 3;
	SetCountText();
}

void Update () 
{
	SetCountText();
}

void SetCountText()
{	Debug.Log(count[0]+"");
	float C = count [0];
	countText.text="Count: "+ C;

}

}

i have also try it with int count; int C= count[0]; and it doesnt work.

mhmmmm :confused:

Ok Mate. if you are having an IndexOutOfRangeException, then it means that you are not initializing the array correctly.

instead of

count[0] = 3;

do

count = new float[3];

check out the following link for the correct way to initialize and manipulate arrays in c#

specially this part

int[] numbers; // declare numbers as an int array of any size
numbers = new int[10];  // numbers is a 10-element array
numbers = new int[20];  // now it's a 20-element array
