Hello,I am trying to implement a camera into my 2d platformer,I keep having issues with this however.The error keep telling me this: a namespace cannot directly contain members such as fields or methods.Please help,also my code is here
using UnityEngine;
public Transform player;
public Vector3 offset;
void Update()
{
transform.position = new Vector3(player.position.x + offset.x, player.position.y + offset.y, offset.z); // Camera follows the player with specified offset position
}
your public class “classname”:MonoBehaviour {} is missing 
You left out the entire class delcaration!! You can’t just selectively leave out a bunch of random code!!! That’s not a thing!! Everything has to be absolutely PERFECTLY typed!
Tutorials and example code are great, but keep this in mind to maximize your success and minimize your frustration:
How to do tutorials properly, two (2) simple steps to success:
Tutorials are a GREAT idea. Tutorials should be used this way:
Step 1. Follow the tutorial and do every single step of the tutorial 100% precisely the way it is shown. Even the slightest deviation (even a single character!) generally ends in disaster. That’s how software engineering works. Every step must be taken, every single letter must be spelled, capitalized, punctuated and spaced (or not spaced) properly, literally NOTHING can be omitted or skipped.
Fortunately this is the easiest part to get right: Be a robot. Don’t make any mistakes.
BE PERFECT IN EVERYTHING YOU DO HERE!!
If you get any errors, learn how to read the error code and fix your error. Google is your friend here. Do NOT continue until you fix your error. Your error will probably be somewhere near the parenthesis numbers (line and character position) in the file. It is almost CERTAINLY your typo causing the error, so look again and fix it.
Step 2. Go back and work through every part of the tutorial again, and this time explain it to your doggie. See how I am doing that in my avatar picture? If you have no dog, explain it to your house plant. If you are unable to explain any part of it, STOP. DO NOT PROCEED. Now go learn how that part works. Read the documentation on the functions involved. Go back to the tutorial and try to figure out WHY they did that. This is the part that takes a LOT of time when you are new. It might take days or weeks to work through a single 5-minute tutorial. Stick with it. You will learn.
Step 2 is the part everybody seems to miss. Without Step 2 you are simply a code-typing monkey and outside of the specific tutorial you did, you will be completely lost. If you want to learn, you MUST do Step 2.
Of course, all this presupposes no errors in the tutorial. For certain tutorial makers (like Unity, Brackeys, Imphenzia, Sebastian Lague) this is usually the case. For some other less-well-known content creators, this is less true. Read the comments on the video: did anyone have issues like you did? If there’s an error, you will NEVER be the first guy to find it.
Beyond that, Step 3, 4, 5 and 6 become easy because you already understand!
Finally, when you have errors…
The complete error message contains everything you need to know to fix the error yourself.
The important parts of the error message are:
Always start with the FIRST error in the console window, as sometimes that error causes or compounds some or all of the subsequent errors. Often the error will be immediately prior to the indicated line, so make sure to check there as well.
All of that information is in the actual error message and you must pay attention to it. Learn how to identify it instantly so you don’t have to stop your progress and fiddle around with the forum.
Remember: NOBODY here memorizes error codes. That’s not a thing. The error code is absolutely the least useful part of the error. It serves no purpose at all. Forget the error code. Put it out of your mind.
I am sorry I am very new to programming where would I put the mono behaviour thing your talking about at. If you have the time could you type out my code with the mono behaviour thing in it.
That’s not going to be helpful.

The purpose of this forum is to assist people who are ready to learn by doing, and who are unafraid to get their hands dirty learning how to code, particularly in the context of Unity3D.
This assumes you have at least written and studied some code and have run into some kind of issue.
If you haven’t even started yet, go check out some Youtube videos for whatever game design you have in mind. There are already many examples of the individual parts and concepts involved, as there is nothing truly new under the sun.
If you just want someone to do it for you, you need go to one of these places:

Thank you so much for telling me how to get started however i hvae a question,The link you gave was for Unity3D,I am sure it would work for 2D I justr need to know if it will do the same or if theres a better place for learning mainly 2D
There is no Unity2D.
Unity’s scene window can be used in 2D mode.
There is a 2D physics package (Physics2D) and a 3D physics package (Physics)
etc.
It’s all the same program always.
If so then what course would help me with 2D,I plan on having my first game be a 2D platformer,in fact I have everything working except for death,respawn,enemies, and the camera following the player. Do you know of any courses that would teach me that.
The obvious first course is to target tutorials for either the game type you have in mind (2D platformer) or else go for specific mechanics once you begin to understand the parts.
Be sure to read my post #3 above for how to do tutorials to avoid wasting your time without doing Step #2.
a prompt for you: every script in Unity is a Class.
To clarify, what Kurt meant was that “Unity3D” is simply just a brand name. There are no “3D-only” or “2D-only” versions of Unity - Unity supports both 3D and 2D workflows, and the docs can usually apply to both workflows.
