 explanation = '''  \n
 An Explanation of how this (color thing) works: 
 Vexcode uses a system at its core called pyodide. This system allows for python to be executed in a browser.
 A feature of the system vexcode uses is the ability for n-way communication between workers and hosts. This
 is how vexcode is able to communicate with its renderer which renders the robot.
 Pyodide not only allows for python execution in javascript, but javascript execution in python. Although slightly
 paradoxical, this feature is how the vexcode python api is able to communicate with the site. An unforseen consequence
 of this is that not only can the vexcode api communicate with the browser, but so can I. Using the simple code, 
 js.eval('postMessage...etc'), we can send the same commands vexcode does. It took me a little while but I managed to
 reverse engineer the command system vexcode uses.

 The following is a list of every command I found:
 WorkerAlive - Communicates with the system to tell it that the worker is not stuck. This is how I circumvented the requirement for waits in loops
 PythonReady - Send when the code is ready
 PythonInitError - An error occured while initializing
 PythonError - Throws an error which gets printed in the main console
 PythonRunning - Send when the code is running
 PythonRunComplete - Sent when the code has completed running
 UnityCommand - Command sent from the unity engine backend (yes, the game engine)
 WaitForUnityReady - Honestly I dont know
 PrintText - print text to the console (literally brain.print)
 PrintNewLine - Prints a newline
 PrintSetColor - This is a fun one. This command allows for any color to be set to the brain color. The parameter for this is color.
                It accepts a hex value, like #FFFFFF
 PrintClearLines - Clears the console line by line
 UpdateBraintimer - Updates the internal brain timer
 PythonVariableValues - Internal command for monitor_variable
 PythonSensorMonitor - Updates the internal sensor monitor?
 PythonStopProject - Stops the project'''

	An Explanation of how this (color thing) works:
	Vexcode uses a system at its core called pyodide. This system allows for python to be executed in a browser.
	A feature of the system vexcode uses is the ability for n-way communication between workers and hosts. This
	is how vexcode is able to communicate with its renderer which renders the robot.
	Pyodide not only allows for python execution in javascript, but javascript execution in python. Although slightly
	paradoxical, this feature is how the vexcode python api is able to communicate with the site. An unforseen consequence
	of this is that not only can the vexcode api communicate with the browser, but so can I. Using the simple code,
	js.eval('postMessage...etc'), we can send the same commands vexcode does. It took me a little while but I managed to
	reverse engineer the command system vexcode uses.

	The following is a list of every command I found:
	WorkerAlive - Communicates with the system to tell it that the worker is not stuck. This is how I circumvented the requirement for waits in loops
	PythonReady - Send when the code is ready
	PythonInitError - An error occured while initializing
	PythonError - Throws an error which gets printed in the main console
	PythonRunning - Send when the code is running
	PythonRunComplete - Sent when the code has completed running
	UnityCommand - Command sent from the unity engine backend (yes, the game engine)
	WaitForUnityReady - Honestly I dont know
	PrintText - print text to the console (literally brain.print)
	PrintNewLine - Prints a newline
	PrintSetColor - This is a fun one. This command allows for any color to be set to the brain color. The parameter for this is color.
	It accepts a hex value, like #FFFFFF
	PrintClearLines - Clears the console line by line
	UpdateBraintimer - Updates the internal brain timer
	PythonVariableValues - Internal command for monitor_variable
	PythonSensorMonitor - Updates the internal sensor monitor?
	PythonStopProject - Stops the project'''
