What's the problem with this line?[C#]

Unity Engine
1

I have a code in C# for rotation(I have no idea how to use C#, i use java) that i got from somewhere(the only script in my game that isn’t written by me). And i need to use this line but it says there’s a problem. Can anyone tell me what it is??

Line:

if(gameObject.GetComponent("playerControl").controllable){

Error:

And to be honest, I have no idea what that error says because i never us C#, always java. But anyway, can someone please reply.

Edit:
The same problem is still there. This is how I put the variable for the GameObject in the C# file:

Code:

public GameObject thePlayer;

and my new line is:

Code:

if(thePlayer.GetComponent("playerControl").controllable){

And controllable is a boolean btw.

Ohhh, i cant access a variable in another script format can I??

3

if(GameObjectVar.GetComponent(“ScriptName”).VarName){

GameInit.GetComponent(TerrainGenerator).TerrainPieces*.Terrain;*
is an example of a line I used.

So GameObjectVar is a var I make up for the gameObject. And VarName is whatever my var from the other script is. Correct?

Edit: the same problem is still there. This is how I put the variable for the GameObject in the C# file:

public GameObject thePlayer;

and my new line is:

if(thePlayer.GetComponent("playerControl").controllable){

And controllable is a boolean btw.

Since C# is fully typesafe, when you call just GetComponent(“ScriptName”), it returns a “UnityEngine.Component” base object. You would need to explicitly cast it as your custom script name:

PlayerControl targetScript = (PlayerControl)gameObject.GetComponent("PlayerControl");
if (targetScript.controllable)
{
}

Even better is to use generics:

PlayerControl targetScript = gameObject.GetComponent<PlayerControl>();
if (targetScript.controllable)
{
}

New problem. Now the error is:

error CS0246: The type or namespace name `playerControl' could not be found. Are you missing a using directive or an assembly reference?

I think that’s saying it cant find it. But i am 150% sure that the JavaScript “playerControl” is ther and I changed the line to:

playerControl targetScript = gameObject.GetComponent<playerControl>();
if (targetScript.controllable)
{

Your JavaScript might have to be put in a “plugins” folder. Essentially, C# doesn’t see it unless it’s compiled first.

EDIT: generally speaking, it’s better if you can stick to having all your code in a single language.

Ok well, can anyone tell me where i can get the MouseLook script in JS? because I have no idea how to translate it from C# to JS.
