Hi I'm new to java script so this is probably really easy but is there a way to detect a key press such as the up arrow.

This is my current code.

 function onCreate()
    {
    	orb.setVelocity( 10 );
    	if(eval((Input.GetKey(KeyCode.KeyUp)))){
    	    orb.TurnUp(5);
    	}
    }

Yep, that should work. Looks like you're missing a semicolon inside of your Eval; fix that and you should be good to go.

I tried that still didn't work.

This is the error message I get.

ERROR:spell1:Spell error when trying to execute function (onCreate):
ReferenceError: Input is not defined

I'm guessing that the error is that CodeSpells doesn't know KeyUp?

Ah, yeah. Unity doesn't use "KeyUp". Instead you can either use Input.GetKey("up"); or Input.GetKey(KeyCode.UpArrow);. Here's the Unity documentation on Input.GetKey(): https://docs.unity3d.com/ScriptReference/Input.GetKey.html

KeyUp is an event that occurs when a key is released. So, you can use Input.GetKeyUp("up"); to check whether the key is being released. It is an event that occurs during the frame that a key is released.

OK. Thanks. Sorry for the late reply.
