Error CS0103: The name 'print' does not exist in the current context

Unity Courses Talk

Hi,

When I enter the code from the lecture:

void Start () {
print (“Welcome to Number Wizard!”);
print (“Pick a number in your head but don’t tell me”);
}

Nothing displays to the console when I run the program in Unity. When I place the pointer over print, I get a popup that says “error CS0103: The name ‘print’ does not exist in the current context”.

I have the script attached to a game object that is inside the scene.
I am fairly certain my code looks like the code in the lecture.

Does anyone know if there is some setting I have to set that I may have missed? Any other suggestions?

Hello @Douglas_Atkinson,

Could you paste up the full script please and we’ll take a look :slight_smile:

Here is the full script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class NumberWizard : MonoBehaviour {

	// Use this for initialization
	void Start () {
		print ("Welcome to Number Wizard!");
		print ("Pick a number in your head but don't tell me");
	}
	
	// Update is called once per frame
	void Update () {
		
	}
}

As far as I can tell it is the same as the one in the lecture except for the addition of the using Systems.Collections.Generic;

Can you take a screenshot? Also, when you hit the triangle play button in Mono develop, can you take a screenshot of that? Most likely you are missing a single character, and your whole problem is a typo.

Hi Doug,

Other users who have experienced similar issues like this have found closing both MonoDevelop and Unity and re-opening can clear the issue. Try the same if you are using Visual Studio.

Your script looks fine.

Closed both MonoDevelop and Unity and restarted. Same problem.

#7

If you want to zip up the project I will have a look at this end for you Doug. You can upload the zip file within your post.

Just a thought, what happens if you comment out your print () statement lines? Will it run in Unity then without error? Admittedly it wont do anything.

I think that the problem may be that I do not have .net framework 3.5 installed on my computer. I have a Windows 10 machine and am having difficulties getting .net framework 3.5 installed. I will keep working on it and once I eventually get it installed, I will see if it makes any difference.

If you have a look inside MonoDevelop, goto project options, and then under build, click on general - there should be a drop down menu with a select assembly, you could try setting it to mono / .Net 2.0 and see of the code runs without issue.

Then grab the more recent framework after.

I am having the same issue and I have a Mac. Tried the last solution but “project option” is block and I am not allowed to click on it. Any other solution?

#11

Do you have any .NET framework installed?
I have .NET framework 4.5 on my Windows 10 machine and not seeing this same issue. I don’t have 3.5 at all on my machine and shouldn’t be a requirement if you have a newer version installed.

Hello Douglas,

It’s been a while since you posted this question, so I want to follow up and ask if you were able to resolve the issue? If not, I’d be glad to help further. Please let me know.

Happy Coding :slight_smile:

I am not sure if this is still an issue for some but thought I would mention this after running into the error myself and spending quite awhile googling too, as @Rob mentioned try leaving a space between print and () because it worked for me.

To anyone who stumbled upon this thread:
Does your class inherit from MonoBehaviour?
If not, use Debug.Log(""); instead.
