        self.sendObj(obj)
    # Loops through every single user
    for Username, User in self.Users.__getallusers__().items():

        if User.input.get(str(pyxel.KEY_SPACE)) and self.variables.visible:
            # Add 1 point to user

    "points": 0
}
GlobalVariables = {
    "pressed": False,
    "x": random.randrange(0, 256),
    "y": random.randrange(0, 144)
}
server.run("127.0.0.1", "5000", 256, 144, 12, update,LocalVariables=LocalVariables, GlobalVariables=GlobalVariables)

What will happen

This is a game of who pressed space first when the dot apears.

server

System

• run(Host, Port, AppWidth, AppHeight, AppFPS, UpdateScript, [WebScript], [InitScript], [Variables])
  Initializes the server and runs it.
  Host: The ip or domain of the server. e.g. Host="127.0.0.1"
Port: The port to be opened in the Host. e.g. Port="5000"
AppWidth: The width of the client's window when connected. e.g. AppWidth=256
AppHeight: The height of the client's window when connected. e.g. AppHeight=144
AppFPS: The FPS of the client's window when connected. e.g. AppFPS=24
UpdateScript: The function to run every 1/AppFPS. e.g. UpdateScript=update
  Note: The function must have the parameter self.
  WebScript: The custom flask events and routes. e.g. WebScript=web
  Note: The function must have the parameter self & app.
  InitScript: The custom initialization function that will be called when server() is called. e.g. InitScript=init
  Note: The function must have the parameter self.
  Variables: A dictionary of variables needed. e.g. Variables={"Name": "Value"}

Connection

• sendObj(obj)
  Converts obj to a json format and sends to all of the clients connected.
  obj: The pyxelobj.obj e.g. obj=pyxelobj.obj()

Data

• variables
  A class of all of the global variables.
  Note: The class will not be created if no global variables are specified in self.run()
  e.g.
  variables.Name = "Value"

Users

• Users.__getuser__(user)
  Returns the User's class.
  user: The name of the user e.g. user="Name"
• Users.__getallusers__()
  Returns all of the Users in a dictionary in a format like this: {"Name": <Class>, "Name": <Class>, ...}

User

• User.variables A class of all of the user's variables.
• User.key The user's key.
• User.input
  A dictionary of all of the keys pressed in a format like this: {"Button Number": Bool, "Button Number": Bool, ...}
  Note: In the client, you must use btnp(button) for User.input to update.

client

Connection

• run(Host, Port)
  Initializes the client with necessary information.
  Host: The ip or domain of the server. e.g. Host="127.0.0.1"
Port: The port to be opened in the Host. e.g. Port="5000"
  Note: You must run this command before anything that needs to use the client.
• connect(Username)
  Connects the client to the necessary information.
  User: The username e.g. User="Name"
  Note: You must run this command after run before using anything from the client.
• request.post(Route, json)
  Posts data to a specified route and returns json back.
  Route: The path to post e.g. Route="/var"
json: The json to post to the Route e.g. json={"Name": "Value"}

Data

• getGlobalvar(Variable, [Value])
  Returns & optionaly changes a global variable from the server.
  Variable: The variable name e.g. Variable="Name"
Value: The value of variable e.g. Value="Value"
  Note: The variable will be changed before it returns.
• getLocalvar(Variable, [Value])
  Returns & optionaly changes a local variable only accessible to the client from the server.
  Variable: The variable name e.g. Variable="Name"
Value: The value of variable e.g. Value="Value"
  Note: The variable will be changed before it returns.

Input

• btnp(button)
  Checks for a button press (see pyxel documentation) then sends result to the server and returns result
  button: The button to press e.g. button=pyxel.KEY_SPACE
• btnr(button)
  Checks for a button release (see pyxel documentation) then sends result to the server and returns result
  button: The button to press e.g. button=pyxel.KEY_SPACE

Objects

• renderAll()
  Renders all of the objects in client.objects
• addObject(obj)
  Adds an object to client.objects
obj: The pyxelobj.obj e.g. obj=pyxelobj.obj()
• addObject(objname)
  Removes an object from client.objects
• predict(obj)
  Predicts an object's next location by adding obj.addX to obj.x and obj.addY to obj.y
obj: The pyxelobj.obj e.g. obj=pyxelobj.obj(json)
  Removes an object from client.objects
objname: The name of the object to remove e.g. objname="Name"
