Script won't run level (platformer tutorial)
I've seem to screwed up the script beyond my fixing capabilities, I'm new to this you see and have no idea what I'm doing. The problems seem to be coming from the ThirdPersonStatus, GameHUD and LevelStatus scripts. Non of the problems it says make any sense to me. Here is the console:
The errors began when I had to start adding in script for the cutscene camera (when the spaceship flies off), this is around the 100 page mark of the tutorial. Here are my scripts, please help.

This is a HUGE script and the formatting of the post is not correct. I'm sure I don't speak for just myself when I say that you need to either pay the people spending all the time reading it and format it regardless.

Never post that much code at once. You posted an entire script that wasn't even generating any errors and missed the script that was generating most of your errors. Also, format your code correctly - convert tabs to spaces and then use the format code button 101010 at the top to format code in your posts and separate your scripts so that we can tell them apart.
No one has the time or patience to sort out bugs you introduced into scripts this long. Read your error messages: They tell you the script and line number of the error which is more than enough to go on: For example:
- Your LevelStatus error is on line 44 where you broke a comment onto the next line, starting that line with the word "itself", but did not comment it out.
- All of your ThirdPersonStatus (which you didn't include by the way) errors on lines 43, 82, and 85 are all because you are trying to access some variable "lives" which doesn't exist.
- Your GameHUD error on line 65 is again because you are trying to access a ThirdPersonStatus script variable "lives" which does not exist.
