So i have an error in my script that i cant fix and i cant test my FPS game without. I know this is an easy fix but i am new to javascript and i dont even have a key that allows me to type | but i am able to copy and paste it.

The series of videos i am watching told me to put || but then i get the error in the title. So i tried putting only one | and then it came up with a different error

Operator ‘|’ cannot be used with a left hand side of type ‘float’ and a right hand side of type ‘float’.

I dont even know what that means!! If you know what is wrong then please help or if you know how to fix it i could really use your help too.

var Fire : String;
var Reload : String;
var Idle : String;
var Wlak : String;

function Update() 
{
	if(Input.GetAxis("Vertical") | Input.GetAxis("Horizontal")){
		animation.Play(Walk);
	}
	else 
	{
		animation.Play(Idle);
	}
}

function FireAnim() 
{	
	gameObject.animation.Play(Fire);
}

function ReloadAnim()
{		
	
	animation["Reload"].speed = (animation["Reload"].clip.length / Gun.ReloadTTime);
	animation.Play(Reload);
}

So a single bar means Bitwise OR. Every number is stored as a bunch of 1s and 0s, and bitwise OR compares those 1s and 0s.

What you want is actually the double bar ||

I wonder if perhaps you are running into your error because the character for the bar that you are copying is wrong?

Try the shift-\ key over the ENTER key. Try isolating both OR clauses with more parentheses, and add the arguments, like this:

if((Input.GetAxis(“Vertical”) == true) || (Input.GetAxis(“Horizontal”) == true)){
…
}
I’ve run across occasions when .net can’t OR correctly without explicit precedence. Although you certainly did have an error in your code with just one pipe (|) symbol. You tried to do a bitwise comparison of two floating decimal values; your values to the left and to the right of the equal sign were both ‘floats,’ when integers are required. The double-pipe compares TRUE to TRUE or FALSE to FALSE or TRUE to FALSE or FALSE to TRUE. That’s what you want.

Input.GetAxis returns a float, you need to do something like this:

if(Input.GetAxis("Vertical")  > 0| Input.GetAxis("Horizontal") > 0){
       animation.Play(Walk);
    }
    else 
    {
       animation.Play(Idle);
    }
