'RED' and 'BLUE' are [instance variables][1] (compare to [class/static variables][2]). You need to find the instance to access there values. The easiest way to do that is: var cube = FindObjectOfType(...

If you're accessing `counter` from a member function in the same class that counter is declared in, then you can access it without a type identifier. Otherwise you need to put the class name before you...

If I'm understanding your question correctly, you shouldn't need any other variables. Can you do something like this: int minimumWage; int poverty; function Update () { if(minimumWage < poverty/10)...

A draw call is basically a batch of triangles sent to the GPU for drawing. In general every object with a different material creates another draw call (there are ways of combining draw calls, but...

There's two errors. One of which is causing the compiler, and the other of which is just causing broken behavior. You have to assign the output of `Mathf.Clamp()` to something. `inAirVelocity` is...

The problem is that a mutual conversion exists. To quote the [MSDN page][1] on your error.> In a conditional statement, you must be able to convert the types on either side of the : operator. Also,...

You have 2 errors. It looks like you are trying to call the constructor to create a new Vector3. The issues is that there are no constructors that take a Vector3 as an argument (you can copy it, but...

I would do something like this: var scoreMultiplier = 5; function Start () { InvokeRepeating( "DecreaseMultiplier", 30 , 30); //You could easily set this up as a coroutine if you wanted variable times....

I see what you're trying to do, and it could work. It just seems like a rather circuitous way of doing it. I might try something like this. Vector3 offset = target.position - transform.position;...

The general equation for linear interpolation is your second one. Output = (1 - t) * Input1 + t * Input2 It can nicely be expanded to higher degrees (see Bezier curves) and vectorized. Just treat the...

It's because whoever wrote the code is writing it into a Vector3. The `?:` (It's called the conditional/ternary operator) is setting the x value of the Vector3. Then the y component is 0, and the z is...

That's probably the easiest way to do it. Yes. The only thing I would worry about is overdraw. Putting a plane over the whole screen essentially means you have to draw every pixel at least twice. So...

Unity does not include any built-in functionality to implement forcefields, but it provides plenty of tools to set it up. I would set up a system something like this: - Each field source has a function...
