What is it?: A very extensive Train and (well mostely) Metro Addon for FiveM

Basic Functionality list:
  - Spawns a 'synced' (and working/driving) Freight train on the railroad tracks of Los Santos
  - Spawns (1 or 2) Metro carts which can be entered as passenger by the players ("no passenger limit!")
  - Players can WALK AROUND in the moving Metro! :)
  - Players HAVE to buy a Metro Ticket to be able to enter (With (ATM) animated Ticket machine handling)
  - Ticket will 'invalidate' when they have entered so they will have to buy a new one
  - Wanted level handling (refuse passengers from entering when wanted)
  - 'terrorist detection', which means if players shoot while on the train they will get a 4 star wanted level
  - Easily configurable with basic variables
  - Different Bank Messages (for Maze Bank, Bank of Liberty or Fleeca bank)
  - Metro's, Freight Train and their drivers are 'invincible' (to prevent others 'ruining' the game/RP)
  - Players can only EXIT the Metro at the stations (by Pressing [E] by default)
  - Players COULD enter the Metro ANYWHERE (if they have a Ticket Of course), by making it stop (stand in front of it)
  
Known 'bugs' or 'issues':
  - When you enter the Metro as passenger the doors 'will dissapear', why? I don't know, but you can NOT walk through it!
	NOTE: They CAN still be used as cover though (the bottom part), which means the 'collision info' will remain active though.
  - The ticket machines above ground (the green/old ones) DO NOT WORK, I tried for several hours to find them in the archives but
	with no luck. I however did find one that looks like it, but that one doesn't respond at all.
	I MIGHT update that when someone can tell me the model of that ticket machine object, however for now I have left it at that.
	Also because the original game-texture says: "Sorry, this machine will NEVER work", so i thought: lets keep it in lore :P (nice excuse huh? haha)
  - When a player puts a vehicle (which doesn't automatically despawns) infront of the Metro, the Metro will wait there till the
	vehicle is removed for eternity.
  
Questions I've already got from our server member/crew while we where testing this script:
  - Q: Can you make it so you can drive the Freight or Metro?
  - A: Yes, I can.
  
  - Q: WILL you make it so we can drive either of them?
  - A: Already done it, Let's test it :P
  
  - Q: (Player on the other side while i'm driving the train:) Woaha, why the f*ck is my train tripping so hard?
  - A: Well mine isn't, Maybe it's because i'm driving backwards but YOUR game (engine) isn't expecting it.
  
  - Q: So you have now (permanently) removed the feature to drive the trains?
  - A: Yes, I have. And I have even DELETED THE CODE, so I will NOT remake it, since it's not stable enough.
  
  Well that's about the 'main question' I expect to show up (since nearly everyone whom tested it did so to)
  So my basic answer is: NOPE I will note make it like that sorry.
  Maybe there are others whom have managed to do it, and did made a syncing system (server sided or so), I haven't
  and I won't, Sorry. Most of my scripts and server are client-sided with minimal network traffic (via scripting),
  only statistics, financials and owned matterials (like houses, cars or items) are server sided to prevent cheating.
  And since we won't need the train or metro driver missions I can't 'afford' to put to much time in developing something
  stable and thoroughly tested while I'm not going to use it anyway ;)
  
Other Possible Questions:
  - Q: Can I use this on my server?
  - A: Sure you can that's why I've uploaded it :)
  
  - Q: Can you please help me add or make my money/banking system?
  - A: No, sorry. I'm VERY busy with me job and other projects, I decided to share my code's_m_m_lsmetro_01
	   to public for others to use, possibly adapt and for others to learn from them (hence the massive commenting!).
	   I have learned it the same way years ago: Looking at other people's codes and trying what would change things or
	   make it do what I wanted it to do.
   
  - Q: So you're basically saying I "just need to learn" to script/program?
  - A: YES, if you would like to run servers and games like this, and thus use mods, it's DEFINITLY a MUST if you can,
	   it might look hard in the beginning, but trust me: You will be thankful if you learn it yourself :)
	   
  - Q: But you also stated that I can adapt your code right?
  - A: Sure, adapt, improve, or even 'strip(remove) stuff from it' to make it suit your needs
	   NOTE: Please do not just 'destroy the code' by randomly doing stuff and then posting stuff like:
	   'I "changed" this, and now your  code doesn't work anymore'. If that happens I suggest you keep trying
	   till it DOES what you need, investigate about the Native codes, look on other sites for resources and
	   information, you can ofcourse ask questions, no problem. Just keep in mind that I'm not going to (not even
	   able to due to my schedule IF I wanted to)) script all kinds of things for everyone randomly ;) :)
  
  - Q: One more question though: If I can adapt your code, am I also allowed to re-upload it?
  - A: Yes you are! :) BUT please do give credits to me and the original creator on whom's idea this
	   scripted was based and inspired on. (AKA: It's NOT allowed to reupload/publish without credits where due)
  
General adivce (applies to ALL uploading coders):
If this script/addon doesn't do what you wanted it to do, if you think it's "sh*tty" etc, that's all fine, but
just keep that to yourself and find another one that suits your needs (or even better: Make it yourself) ;)
Keep in mind that people upload code to help/provide others in resources and learning matterial, and that doing so
costs (extra) time. Time they took to provide you (and many others) with resources, code, samples and addons.
Contribute, help, share and evolve together, that's the power of a community :)
(Ofcourse doesn't mean that constructive critisim isn't welcome or desired (since we all will always have points of
improvement :) )
  
=================================== Money Handling Information ===================================
 If the rest if TL;DR, fine, your problem ;) :P (Don't nag either if you can't figure it out haha)
 But ATLEAST do read this piece for setup! and IF you have questions, or if want to Adapt or
 re-publish/upload it: Don't be stubborn, respect other peoples work, and DO read the above ;)
===================================================================================================
IMPORTANT NOTE: Bellow 'somewhere' in the code you will find these two lines:
BankAmount = 10000    --StatGetInt("BANK_BALANCE",-1)
PlayerCashAm = 10000  --StatGetInt("MP0_WALLET_BALANCE",-1)

Make sure that you adapt them to YOUR OWN SERVER, since like stated there (in the script to),
many servers use a different money management system, and thus it's not quite possible to make
one that is 'general in use' for all. We use one that doesn't uses the game stats at all (since thats
to easy to influence with cheat programs for example). To make sure that people could test/try this
script i have set the INTERNAL SCRIPT money values to very high (those DO NOT affect the player itself though!)

This also means that there is no money being taken from the player when he/she buy's a ticket

To make sure that money is taken from the player when buying a ticked you will need to find the following code part:
	if PayWithBank == 1 then
		-- Put YOUR code to deduct the amount from the players BANK account here
		-- 'Basic Example':  PlayerBankMoney = PlayerBankMoney - TicketPrice
	else
		-- Put YOUR code to deduct the amount from the players CASH money account here
		-- 'Basic Example':  PlayerCash = PlayerCash - TicketPrice
	end

And add your OWN SERVER money handling/taking code here

I hope this code/addon is usefull for some people or that they might learn from it by using parts of it :)
