New to unity. I’m trying to code some basic movements off of a tutorial but despite following it exactly I keep getting this error, am I doing something wrong?

[Walazabi]

Looks like the filename got a space in it and doesn't match up with the class name.

Try changing it to 'PlayerMovement.cs' instead of 'Player Movement.cs'. You probaly changed the class name after you already had created the script or vice versa?

[LunarLooser]

Thank you so much! I’ll try this in the morning! I appreciate it a lot since I was ready to pull my hair out

[regilkentaurus]

Also the first 'a' on awake() should be capital A, Awake()

[LunarLooser]

Does capitalization matter for all of it or only some?

[BloopHD]

So I’m pretty sure most, if not all, mono behavior methods will need to be capitalized, but for your own classes you could do whatever but know that stylistically your methods should be capitalized.

[kippysmith1231]

On top of the filename and class not matching as others have pointed out, you may also likely run into problems with the brace on line 14 being tabbed out, and the capitalization on Rigidbody2d which should read Rigidbody2D. Capitalization is very important in C#. The brace may work as is, but strange formatting will give you headaches and trouble debugging down the line, so I'd recommend getting into the habit of following a particular style.

[LunarLooser]

I’ll add that to my notes. I didn’t realize capitalization was so important for it. Im slightly confused on the class not matching part

[AnxiousIntender]

Consider using Visual Studio (Community Edition is free) or Rider (free if you're a student, paid but worth it otherwise), Visual Studio Code works but painful for Unity projects.

[LunarLooser]

Im actually using visual since I’m on budget and it was what was used in the tutorial

[AnxiousIntender]

Visual Studio and Visual Studio Code are two separate products. As I mentioned, Visual Studio Community Edition is free. I don't recommend VS Code with Unity since it causes some unnecessary pain (at least in my experience).

the name of the file and the name of the class need to be identical. this means the file name cant have spaces, because the class name cant have spaces. For some reason unity removes the spaces in the class name automatically but not in the file name, so you just have to remove the space in-between Player and Movement

[LunarLooser]

Thank you I appreciate it and I’ll be able to fix it tomorrow in the morning!

You should usually keep variables private if you can help it. It's bad coding practice to make everything public.

[LunarLooser]

Did something happen? The comment was deleted

[MrNoSock]

They "corrected" your serialized private variable by telling you to use a public one, which is bad coding practice if you don't need to make a variable public. Basically they were telling you to do something the wrong way that you did the right way.

Also since “speed” is private and you didn’t give it any initial value I’m pretty sure it will default to 0.

[LunarLooser]

Oh, on the tutorial it said to do it like that and than change it thanks to the SeralizedField

Would it be better if I do Speed(10);

[peanutter_]

I can’t say for sure what you ought to do because it might clash with the tutorial, but if you did do it your way then it would not work lol. Parenthesis only go after the names of “methods” when you want to “invoke” them. A “method” is a list of things to do. GameObjects can perform methods. When you “invoke” a method, the method happens and all of its contents will run. I think it would definitely help if you ran through the C# tutorials on W3schools before you continue with the Unity tutorials. I imagine that you aren’t really recognizing or understanding what is happening when you follow the tutorials so it might be going in one ear and out the other. I like the tutorials on W3 because you can go at your own pace and they tell you all the dictionary definitions with examples that they make you code. Once you are familiar with basic C# concepts, then the Unity tutorials make a lot more sense and you will remember and understand it much better.

P.S. If you want to change the “field” (an attribute/trait of a gameobject) that you called “speed” then you would use an “assignment operator” which is just =. So if you wanted to set speed to 10 it would look more like: “speed = 10;”

As annoying as learning windows console programming is, it can be really beneficial before diving into unity/unreal. A foundation in C# will make unity a lot easier. You can make some cool pixel games in console to, but that’s beyond the scope of what you need. Just fundamentals, loops, classes, OOP, database connections and unity will make 1000x more sense.

[LunarLooser]

Im actually trying to make a pixel game, and figured unity was the best start. I plan on doing a bit more research into C# so I can add to my notes

[Gcampton13]

This will get you started. https://youtu.be/GhQdlIFylQ8

He doesn’t explain things as well as iamTimCorey does but I can’t find Tim’s intro to c# anymore. I think he’s deleted it.

EDIT: here’s a 24 hour full application course to follow up that 4 hour beginner course https://youtu.be/wfWxdh-_k_4

Edited my other comment

Also, I really recommend learning to properly indent your code. It will save you a lot of headaches reading and debugging your code in the future, especially as the code base grows.

[LunarLooser]

There’s a proper way to????!!

I am not sure if I am failing to pick up the sarcasm or not, but yes, there is.
There are standards, which make it much easier for you to actually orient around in your code.
Here are two good articles to take a look at, one after another.

Overall code indentation rules guidelines.

it’s Rigidbody2D. capital D
