Stoopid Question Time - Need Advice.

Hello All,

Trying to be a conscientious developer, I just backed up the files I had of a game, I just had a an incident that took over a week to fix and lost quite a bit of work. So just to check that the backup went fine and was working I opened it back up in Unity5.6.1 yes I haven't upgraded yet I'm terrified of having another incident like I just had.

Anyway, I have no idea how to open the project I just backed up so I went into Unity and opened the project by the scene file, to make sure i didn't open in Unity 2017,and after it loaded up the scene/project preceded to tell me there are errors in the file, and wouldn't run.

So, what do I have to do to make sure the backup is in working order, so, I can have a working copy of the game if it goes belly up again?

EDIT: I loaded up the original file just now and now it isn't working either!?!?! I can't fraking understand Unity. I fraking give up .

Thankyou and Regards.

 

look up using Version Control with unity, its much better than manual/file copy backups..(as long as you commit your changes often, you'll be safe)

 

I look into if I can't get this version of the game working again! 3 months work down the tube . At least I have all the source files, so, worst comes to worst I can type it out all over the source files again - the nightmare part by far will be doing all the animation files again

For a starting point what do you use?

 

Did not know that!

Would opening the project using a scene like I did cause both the backup and original file to stop working? Or, have I really screwed up my project good and proper in some other way?

 

Well, it a bit hard to define stopped working. The inventory system stopped working giving me errors I can no longer pick up or drop items, there are problems with the player prefab, no longer producing the correct weapon number I have to set a default value because it won't accept the line in the script anymore, the camera following script just stopped altogether, no errors. I understand what the errors are, but, I cannot correct them. The dialog system is also giving me problemsw. Like I said the code was working before I went and saved a backup and started it up again. I have checked over the code again and again and everything is the same.

I had the same errors a week ago, that fixed up after replacing the player prefab with an older prefab and went through the code with a fine tooth comb fixing the errors and function that had been mysteriously disappeared with a number of prefabs putting them back again, and it worked only to get them back.

NullReferenceException: Object reference not set to an instance of an object
PickupScript.Start () (at Assets/PickupScript.cs:30)

NullReferenceException: Object reference not set to an instance of an object
Slot.Update () (at Assets/Slot.cs:37)

NullReferenceException: Object reference not set to an instance of an object
Player_Attack.Update () (at Assets/Player_Attack.cs:95)

NullReferenceException: Object reference not set to an instance of an object
PickupScript.OnTriggerEnter2D (UnityEngine.Collider2D col) (at Assets/PickupScript.cs:50)

These errors would seem to be no-brainers but the code did work, everything was defined correctly, something is very wrong I know there is, but, I don't know what it is. Yeah, I know what you are thinking you are just a stoopid noob and for a lot of things I would agree. So much so that I am about to spend $100 trying to rollback the computer to before the errors occurred.

 

Okay I tried setting up a version control thingy using the following webpage:

https://unity3d.com/learn/tutorials/topics/cloud-build/creating-your-first-source-control-repository

And it said to install the software called SourceTree and it wouldn't install. So, does anyone have an alternative to the software I should be using?
