New computer transfer issues

[Torren1292]

Hey guys, I have recently purchased a new pc and upon copying over my project to it I have quite a few errors that I don’t know how to deal with. On my old computer, there are no issues and everything is fine. On my new computer, I have 67 errors in the console, all pertaining to type or namespace not existing. I have gone through and compared everything on both pcs and am not finding any differences beyond the error existence. I feel like it is an assembly issue. I’ll post a sample of just one of the errors

using System.Collections;
using System.Collections.Generic;
using TMPro;
using UnityEngine;
using UnityEngine.UI;

namespace Inventory.UI
{
    public class UIInventoryDescription : MonoBehaviour
    {
        [SerializeField]
        private Image itemImage;
        [SerializeField]
        private TMP_Text title;
        [SerializeField]
        private TMP_Text description;


        public void Awake()
        {
            ResetDescription();
        }

        public void ResetDescription()
        {
            itemImage.gameObject.SetActive(false);
            title.text = "";
            description.text = "";
        }

        public void SetDescription(Sprite sprite, string itemName,
            string itemDescription)
        {
            itemImage.gameObject.SetActive(true);
            itemImage.sprite = sprite;
            title.text = itemName;
            description.text = itemDescription;
        }
    }
}

In this code, it is telling me that the type “TMP_Text” does not exist and even has TMPro at the top underlined. Again, this is one example, another being that GetComponent does not exist in the current context (on a class inheriting monobehaviour)

Hopefully this is a simple fix and I can just reload everything, but I don’t know how as I have never had to.

Hopefully you’re using source control and pulling from that source control onto the new computer.

Either way, sounds like you just didn’t install something correctly or failed to hook something up. Make sure in Unity it’s pointing to Visual studio under preferences → External tools. Also make sure all your packages are properly installed on the new computer. While this should go with the json file in the Packages folder, if you failed to move something over, you might get that error.

Thus, my mention of using Source control.

You should share projects between computers using source control and nothing else.

This might also be an issue:

Extra unwanted packages in new projects (collab, testing, rider and other junk):

Temp/UnityEngine.TestRunner.dll Error

Recent versions of unity have an annoying habit of crapping useless packages into your project. When those packages inevitably have errors, this sort of thing happens. I have railed about it before. Go into the package manager and remove crap you don’t need, like the entire test runner and collab and whatnot. If you feel brave you can hand-edit the Packages/manifest.json file a lot faster than using the laggy package manager interface that only lets you remove one package at a time: [7287748-…

About the fastest way I have found to make a project and avoid all this noise is to create the project, then as soon as you see the files appear, FORCE-STOP (hard-kill) Unity (with the Activity Manager or Task Manager), then go hand-edit the Packages/manifest.json file as outlined in the above post, then reopen Unity.

Sometimes the package system gets borked from all this unnecessary churn and requires the package cache to be cleared:

PROPERLY CONFIGURING AND USING ENTERPRISE SOURCE CONTROL

I’m sorry you’ve had this issue. Please consider using proper industrial-grade enterprise-qualified source control in order to guard and protect your hard-earned work.

Personally I use git (completely outside of Unity) because it is free and there are tons of tutorials out there to help you set it up as well as free places to host your repo (BitBucket, Github, Gitlab, etc.).

You can also push git repositories to other drives: thumb drives, USB drives, network drives, etc., effectively putting a complete copy of the repository there.

As far as configuring Unity to play nice with git, keep this in mind:

Prefab links keep getting dumped on Git pull

There really isn’t any fix because git works perfectly with Unity when configured properly. Best practices involve saving your work and closing Unity before using git. But if you understand how Unity does and does not flush changes to disk (or at least ALWAYS do a save-project), you can get away with leaving Unity open. The only thing linking EVERYTHING together in Unity is the GUID assigned to a script or asset. Name is irrelevant. Only the GUID connects it. This GUID is in the meta file. I…

I usually make a separate repository for each game, but I have some repositories with a bunch of smaller test games.

Here is how I use git in one of my games, Jetpack Kurt:

2 steps backwards

Yeah, what Praetor said is it… Debug.Log is your friend, and also since this is animation related, you can open up the Animator window when you expect the animations to go, and actually visually see where the state machine is, see which state it thinks it is in. You can combine this with Debug.Log() output at the locations where you set the animations to be what you think they should be, and that should lead you to some intel. I highly recommend setting up git source control. It really plays ni…

Using fine-grained source control as you work to refine your engineering:

When to make a separate object or class/script? Help me think like a programmer! (Example in text.)

This is a reasonable initial approach. The problem is you have listed the parts, but you haven’t really listed how they interact, and even if you did, it’s still sorta up to you how to organize it. Only YOU will know how to organize it, and the only way you can tell is to do the work. I recommend this: first, develop ALWAYS with source control (such as git), and every time you get even the slightest thing working, commit those changes with good commit messages. Then move to the next thing, c…

Share/Sharing source code between projects:

Your techniques to share code between projects?

I have found that bundling your own code into DLLs only serves to slow down your workflow. I base this on several years of experience dealing with other teams well-intentioned packaging mishaps. With games, it is almost always useful to reach into library code, make a temporary tweak to isolate a problem, and then revert it. With DLLs this is impossible, making workflow harder and more brittle. I prefer to share source code at the C# level. That way I can reach into libraries trivially and inje…

Setting up an appropriate .gitignore file for Unity3D:

Removing IL2CPP_cache from Project

Not sure what you are "auto generating" with... I usually start from one of my other projects, or a gitignore example online, and reason about all the parts inside it, and start from there. Like any other configuration change, after you make it, pay attention for a while to make sure it is what you want. You can always clone the repo somewhere else to verify that the correct files are being tracked. Doing so to a brand-new computer is the acid test to make sure you can still bui…

Generally setting Unity up (includes above .gitignore concepts):

How to Git with Unity

It is only simple economics that you must expend as much effort into backing it up as you feel the work is worth in the first place. Digital storage is so unbelievably cheap today that you can buy gigabytes of flash drive storage for about the price of a cup of coffee. It’s simply ridiculous not to back up.

If you plan on joining the software industry, you will be required and expected to know how to use source control.

Close the project, delete all files except “Assets”, “Packages”, and “ProjectSettings”, then open project again:

Thank you all for the replies. I will step through all of this and see what is going on

[Torren1292]

Not the best way of resolving this issue, but I basically brought over the hard drive from my old computer (didn’t need it other than for this project) and everything is fine now. I need SCM
