Need Help With Events

Hey guys,i just wanted to make my own OS.So i need help with Events.especially with Mouse Click Events
Im not asking you an Entire Code i just need to Know how to Use them.I Have Some Experience with Lua Programming
I'm doing this for over a Month and i know how to Handle Several API's.Including Paintutils,Textutils,Term,Os(Not Events)
Colors,RS etc.
Please show me how to make Events…

NOTE - Dont Ask why i Put Capitals on Almost all Words :ph34r:/>

Let me know if this was of any use

Events

Lets start with this

local evt, p1, mX, mY = os.pullEvent()

NOTE: evt or whatever can be named to something else and are just examples

Params

evt
evt is the event that is pulled and returned from os.pullEvent

local evt = os.pullEvent()
	print(evt)

List of Events

• char
• key
• mouse_click
• mouse_drag
• mouse_scroll
• monitor_touch
• monitor_resize
• disk
• disk_eject
• peripheral
• peripheral_detach
• timer
• alarm
• redstone
• terminate
• rednet_message
• modem_message
• http_success
• http_failure
• turtle_inventory

returns a string

p1
Hmm.. What is p1? Well it is the key value that is returned from the os.pullEvent function.
For the mouse the 'key values' for the buttons is 1,2 and 3 ( And for mouse scroll it's 1 and -1 )
Well 1 is basically the left mouse button, 2 is the right button and ofcourse 3 is the middle button.
For mouse scroll events the 'key values' 1 is down and -1 is up

local evt, p1 = os.pullEvent("mouse_click")
if p1 == 1 then
	print("You clicked the left mouse button!")
elseif p1 == 2 then
	print("You clicked the right mouse button!")
end

returns a key value


mX and mY
mX is the x position you clicked on the screen with the mouse cursor and mY is the y position

local evt, p1, mX, mY = os.pullEvent("mouse_click")
print("Clicked: " .. mX .. ":" ..mY)

returns numbers

To check key values and stuff you can run this code in the Lua prompt or a program

while true do
    print(os.pullEvent())
end
