I have a weird problem that no one seems to be talking about. I'm trying to use namespaces for my script mainly to see how it works but no matter how simple the function is it gives me a nullreferenceexception.
heres a example
namespace namespaceExample
{
public class TestClass : MonoBehaviour
{
public void TestFunction(string message)
{
print(message);
}
}
}
class TestClass2
{
public string message = "Hello World!";
namespaceExample.TestClass test;
void Test()
{
test.TestFunction(message);
}
}
can someone explain to my why this happens? I'm using unity 2017.2.0f3

MonoDevelop not recognizing "UnityEngine namespace"
For some odd reason MonoDevelop can't recognize this. I've searched around online and on the forums and nothing seems to work. I've tried uninstalling and re-installing, which at first worked, but the next day I'm back in square one. I've tried setting my .NET framework to the correct version I have installed. I've also tried deleting certain files in the Unity Project Directory as directed by many answers I've found online. Any help would be appreciated! Thanks in advance.

Using variables without overflow
I have a 2 scripts test.cs and test2.cs. I want it test2 to access test, and it works, but i don't want to make a new variable every function. Maybe the code will tell more :D
Current Code (works):
using MrRockis.Test;
namespace MrRockis.Test.Actions
{
public class test2 : MonoBehaviour
{
public void Test()
{
promo = new Test();
Debug.Log (promo.statusText.text);
}
}
}
But i don't want to type "promo = new Test(); inside every function!
This code gives stack overflow error:
using MrRockis.Test;
namespace MrRockis.Test.Actions
{
public class test2 : MonoBehaviour
{
private Test promo = new Test(); //This row gives me the error
public void Test()
{
Debug.Log (promo.statusText.text);
}
}
}
How could i do this without putting "promo = new Test();" inside every function?

Best way to communicate between scripts
Hello everyone. I would like to know what is the best way to communicate between scripts without referencing them through the inspector. I've found some very helpful answers but I'm not sure which is best and why. For example, we have a main script where all our info is saved or loaded and some secondary scripts with info. Most secondary scripts will need to use values from our main script pretty commonly and i know for sure `GetComponent` is not the best way to do it, especially if you are going to reference them a lot . I could also create a variable and then drag the game object that holds the main script to it but then i would need to do that for every single secondary script and some scripts may need to be destroyed in runtime or some game objects may change many times which i think is waste of time, which is why I'm interested in being able to make a whole class static and use it's values or perhaps use namespaces? Any help would be appreciated and sorry for the confusing, I'm really confused as well!

Types and namespace not found...
Ok, so I'm new to Unity and C# but I wrote a tiny script which runs without a problem inside Unity.
But when I try to export it (build) I get a bunch of errors all telling me types are not found, and it's pretty much all the types I used... So it doesn't find MonoBehaviour, Vector3 or Transform.
The script looks like this :
* using System.Collections.Generic;
using UnityEngine;
public class CameraBehaviour : MonoBehaviour {
Vector3 myVectorZ;
Vector3 myVectorY;
Vector3 myVectorX;
Transform myTransform;
void Awake () {
myTransform = GetComponent ();
myVectorZ = new Vector3 (myTransform.position.x, myTransform.position.y, myTransform.position.z+2);
myVectorY = new Vector3 (myTransform.position.x, myTransform.position.y+2, myTransform.position.z);
myVectorX = new Vector3 (myTransform.position.x+2, myTransform.position.y, myTransform.position.z);
}
// Use this for initialization
void Start () {
}
// Update is called once per frame
void FixedUpdate () {
if ( Input.GetKey( "space" ) )
{ transform.Translate( myVectorZ , Space.Self);
Debug.Log ("Fixed :");
Debug.Log (myTransform.position.z); }
}
void Update () {
if ( Input.GetKey( "space" ) )
{ transform.Translate( myVectorZ , Space.Self);
Debug.Log ("NotFixed :");
Debug.Log (myTransform.position.z); }
}
} *
I'm guessing I didn't think of a simple thing that ruin everything but I didn't find an answer fitting my problem.
Sorry if I'm not clear, not english... Thanks in advance for your answers !

Any reason not to use namespace for scripts for asset store
I noticed that some asset store packages name their assets like this company or project name _ then a class name (like vp_Something). This might be to find the classes from a specific asset faster and to know which classes belong to which asset while typing. But this can be also done with namespaces. Is there any reason to do this instead of CompanyName.ProjectName.ClassName. Also is there any document that defines the default way you should name classes and namespaces for unity asset store?

Custom namespace not found by Assembly-CSharp-firstpass,My custom namespace isn't found in Assembly-CSharp-firstpass using VSCode
I work using two namespaces: one that is game specific, and one that has utitlities that can be re-used by other games. I'm finding that my generic one is not being found by Assembly-CSharp-firstpass in VSCode. So, I lose all my intellisense, and I get lots of red error messages that are annoying.
The game compiles fine and runs as expected, but I want my intellisense working. I'm not sure how this firstpass project works. How can I make it so my namespace is found?
,Hi there,
I'm using VS Code with Unity 2017.3.0f3, and I'm finding that one of my custom namespaces isn't being found by CSharp. But, other namespaces from say a plugin, are found. When I run my app in the Unity Editor, everything works fine, so my namespace is eventually found when the project is built. But, for some reason, when working in VS Code I'm getting intellisense errors. It's annoying, and it's slowing me down, so I want to solve it.
I'm basically working with two namespaces: one that is game specific, and then I have a general one with utilities that are generic. It's this generic one that isn't found.
Any help is appreciated on how I can solve this.

UnityEngine does not exist in this context
Version: Currently 2017.4.1f.1, repeatable in other versions
Exists in both monodevelop and visual studio
C# coding for Windows and AndroidSDK
Currently affects all scripts using.UnityEngine and children.
Currently I'm having an issue with my project where the editor and monodevelop/visual studio both loose access to UnityEngine, despite it being clearing in my Reference library. I've looked through multiple different versions of this question that have appeared for multiple versions and years of unity with no luck. I'm looking for some idea of what could cause this as I've made no changes to any of those libraries before hand, and it seems random when it happens if I revert back to a backup.
Attempted Solutions:
Delete Library folder
Delete all .csproj and cln files to remake them
Reinstalled Unity
Install a different version of Unity
Reinstall Monodev/VS
Reimport Assests
Reimport All
Change .NET framework version
Remove GoogleAds plugin(originally thought this was the issue but this happens without the plugin present as well)
Tried readding the Reference to the UnityEngine.dll
All of these were suggestions I've found in my search, and while they seemed to work for some very sporadically, none of them have fixed my issue.
In addition I am unable to post any code for this project for various reasons, though this issue affects all scripts currently.

Unity won't build on Windows after reinstall
I am in need of fixing this problem right away. I am a college student and the game I'm making it's my final career project, deadline in 2 days.
----------
Description:
I made my project with Unity 2017.3.0f3. The other day i realized I had only installed the Windows build (As in, no MacOS, no Linux, no anything) and so I uninstalled and installed the exact same version. But now, Unity will not build my game for release on Windows at all.
----------
Errors pop out whenever I try to build the game on its own executable. The error I'm getting is the same type for everything: "The type or namespace 'SOMETHING' does not exist in the namespace 'UnityEngine'. Are you missing an assembly reference?" The game works perfectly fine on the editor and Visual Studio does not seem to detect any error at all. It only happens when I try to build a .exe.
----------
Literally every script, even the ones from the asset store packages I got and the ones I made, have this kind of error and the game will simply fail to build. I've tried the following to no avail:
----------
1. Reimport all assets
2. Delete the library folder to force Unity rebuild it
3. Delete the .sln files to force Unity rebuild them
4. Uninstalling Unity, turning computer off and on, Installing, turning computer off and on again.
----------
None of the above worked. What are my options? I really need to salvage the project with all of its scenes, scripts and assets and be able to build it. This problem is really getting on my nerves and I have no more ideas.

Can't use namespace 'TMPro' with the TextMeshPro Package (2018.2.0f2)

Whenever I try to use the namespace 'TMPro' in Unity 2018.2.0f2, it says that the namespace doesn't exist. And when I try to open the TextMeshProUGUI.cs in the solution explorer, it says that the file doesn't exist neither.
However if it did compile in a previous version (2018.1.0f2) and it works fine, but I can't modify the script in my current version. Could this be a bug?
