Im new so if you're ganna flame me then don't read this

Question

So I just started learning Unity and Java at the same time, and I'm a rank 1 newbie. The project I'm working on has a ball that moves side to side on a flat plane with the ability to jump. I'm writing this in Unity 5.1 and the tutorial I'm watching is in Unity 4.x. I have the exact code of the tutorial copied down, but being new to Java I have no way of knowing why Unity 5.1 is not accepting the code, nor do I have a direction in which I can start to look.

Here are the errors I am receiving: Assets/MoveBall.js(13,26): BCE0043: Unexpected token: ). Assets/MoveBall.js(13,27): BCE0044 expecting ), found '.'. Assets/MoveBall.js13,28): UCE0001 ';' expected. Insert a semicolon at end. Assets/MoveBall.js(17,26): BCE0043 Unexpected token: ). Assets/MoveBall.js(17,26): BCE0044 expecting ), found '.'. Assets/MoveBall.js(17,28): UCE0001 ';' expected. Insert a semicolon at end.

I don't understand the errors that are appearing. For instance it says that lines 13 and 17 expects a semicolon. but there is clearly a semicolon right there at the end, so I just don't get it. I'm probably not understanding how to read the error messages, but for the life of me I don't even know how to ask google what I am doing wrong, and this is driving me insane because i literally just picked this up and it's already broken.

 GetComponent<Rigidbody>()

to

 GetComponent.<Rigidbody>()

note the dot after GetComponent it required in java

Do you get any error? It does move on my test scene. Did you attach script to the ball? Does it have a Rigidbody? Does Is$$anonymous$$inematic unchecked?

Ok that was it, somehow the script was unattached from my ball, which is weird because I didn't delete my script or my ball. Regardless thank you Positive7 you are amazing :)

It's because you're using JavaScript; GetComponent<Rigidbody>() works for C#, but not JS. You have to place a "." after GetComponent. Here are the two ways you can write this:

 GetComponent.<Rigidbody>().AddRelativeTorque(Vector3.back * rotation);

or

 GetComponent(Rigidbody).AddRelativeTorque(Vector3.back * rotation);
