2 Nerds

sequenceDiagram
actor Alice
actor John

Alice->>John: Hey i have built a new game?
John-->>Alice: Great!
Alice-)John: You want to see it?
John->>Alice: Why not

How can the Alice share the code ?

1. Zip it , and share it?
   (whatsapp, g drive, telegram , onedrive, pendrive,)

Then whats the point of git?

actor Alice
actor John

Alice->>John: How was the game?
John-->>Alice: Great!
Alice-)John: I have made a new level
John->>Alice: Can i have it ?
Alice->>John: Sure

sequenceDiagram
actor Alice
actor John

John->>Alice: Hey i also made some changes to the game ?
John-->>Alice: Like what!
Alice-)John: new character and new items
John->>Alice: Great , but im not sure if this both will be compatible
Alice-->>John: Hhat should i do

• John has 3 options
  • 1 Delete the old game , or backup the game somewhere else and copy the new game
    • Problem 1 : Data will be lost
    • Problem 2 : twice the disk usage
  • 2 Manually figure out how to integrate these 2 changes

With Git

Alice's Game

class Game1:
	def level_1(args):
		...
	def items():
		...
	def characters:
		...

John's Game

class Game1:
	def level_1(args):
		...
	def level_2():
		...
	def items():
		...
	def characters:
		...

What have changed (demo)

Why this is more efficient

1. Once a Alice create a game and send that John , he dont have to do anything else ,
2. John can look at the changes
