Question

I have an array learnnum that looks like [0,1,1,0,1,1,1,1,0].

I need to basically ask the user for an input Left Mouse Button or Right Mouse Button. If Left, then the values of learnnum of [i] is flipped, else nothing happens. I only do this for i=1,3,5,7. I have written the below code, but it does not work properly, instead of going for all the 4 conditions… it directly goes to 4. It seems that it is not waiting for the input conditions… Is there any way I can correct this?

function changeNumba(i)
{       //check1=true;
        print ("PRINTT "+check1);
                    while(!Input.GetButtonDown("Fire1") && !Input.GetButtonDown("Fire2"))
                    {
                    if(Input.GetButtonDown("Fire1"))
                    {
                    check1++;
                    }
                if(Input.GetButtonDown("Fire2"))
                    {
                    learnednum[i]=0 ? 1 : 0;
                    check1++;
                    }
                }

}

function changelearn()
{       

        //FIRST STEP
        //if(check1)    
        if(move1==9 && check1==0)
            {changeNumba(1);

            }
        //SECOND STEP   
        if(move1==9 && check1==1)
            {changeNumba(3);

            }
        if(move1==9 && check1==2)
            {changeNumba(5);

            }
        if(move1==9 && check1==3)
            {changeNumba(7);

            }
}





var check1=0;

//1,3,5,7
function Update () {


if(move1==9)//this is just a game condition. Do not bother about it.
{
changelearn();
}

 }

from looking at the unity script api:
http://docs.unity3d.com/Documentation/ScriptReference/Input.GetButtonDown.html

you should not have a while() loop inside of your Update() method.

change changeNumba() as follows:

function changeNumba(i)
{
if(Input.GetButtonDown("Fire1")){
    check1++;
}
if(Input.GetButtonDown("Fire2")){
    learnednum[i] = learnednum[i]==0 ? 1 : 0;
    check1++;
}
}
