Problem with updating an integer.

Questions & Answers
1

I have a gameObject that I am trying to get the rotation.x of. This is then to be saved to an integer called velocity. The problem is, I am getting the 'Expressions in statement must only be executed for their side-effects" error. I know this means that my code isnt doing anything and this may be due to C# handling the integer in a certain way that is different to unityscript.

The code is as follows:

var changeType : changeMaterialType;
var catapult : GameObject;
var velocity : int;

function Start(){
velocity = 0;
}

function Update () {
	
velocity == catapult.transform.rotation.x;	

if(rigidbody.isKinematic == false)
{
	if(constantForce.force.y >= -50)
	{
		gameObject.constantForce.force.y -= changeType.currentProjectile.rigidbody.mass * 10/velocity;
	}

	if(constantForce.force.z <= 10 && constantForce.force.z >= 0)
	{
	gameObject.constantForce.force.z += 1;
	}
	if(constantForce.force.z == 10)
	{
	gameObject.constantForce.force.z -= 2;
	}
}
}

I have the velocity int starting at 0 and want it to be equal to the rotation of my catapult gameobject when updating.

This line is strange:

velocity == catapult.transform.rotation.x;

since it’s a double “=” outside an if statement. It should be

velocity = catapult.transform.rotation.x;

But I’m not sure this will solve all your problems.
