Unexpected token if
Hi im new in unity and im trying to make an object float in the water and i make a script but gives me an error. This is the code can someone help me? :
var waterlevel : float =4;
var floatheight : float = 2;
var bouyancyCentreOffset : Vector3;
private var forceFactor : float;
private var actionPoint : Vector3;
private var upLift : Vector3;
function Update ()
{
actionPoint = transform.position + transform.TransformDirection(bouyancyCentreOffset);
forceFactor = if - ((actionPoint.y = waterlevel) / floatHeight);
if (forceFactor > 0f)
{
upLift = -Physics.gravity * (forceFactor - rigidbody.velocity.y * bounceDamp);
rigidbody.AddForceAtPosition(upLift, actionpoint);
}
}
You got that from the vid on youtube :)
It's a good script to have found but you did not "make" it :D
You have a typo on line 11. You have typed "if" it should be 1f
But now the "=" before 1f gives an error dont know why, what can i do?
Yep you had more than just the one error. The second = on that line should have been a - . You had various uppercase/lowercase typos, and you had not declared "bounceDamp" or initialized it.
I found the tutorial and checked your script against it, this should be it without the errors :
var waterLevel : float = 4.0;
var floatHeight : float = 2.0;
var bounceDamp : float = 0.05;
var bouyancyCentreOffset : Vector3;
private var forceFactor : float;
private var actionPoint : Vector3;
private var upLift : Vector3;
function Update() {
actionPoint = transform.position + transform.TransformDirection(bouyancyCentreOffset);
forceFactor = 1f - ((actionPoint.y - waterLevel) / floatHeight);
if (forceFactor > 0f) {
upLift = -Physics.gravity * (forceFactor - rigidbody.velocity.y * bounceDamp);
rigidbody.AddForceAtPosition(upLift, actionPoint);
}
}
Have fun, it really is a great little script :D
Edit : For completeness for anyone who likes this script, and as it only seems fair to the guy who made it and the tutorial, here is a link to it :
