Help understand programming touch screen and setting up gui.

[TheRedInventor 0]

I am trying to program an info board with options for players to choose. Each button opens up text to give info to the player.

local event = require("event")
local comp = require("component")
local term = require("term")
local colors = require("colors")
local computer = require("computer")
local gpu = component.gpu

term.clear()
term.setCursor (1,1)
gpu.setBackground(colors.green)
gpu.setForeground(colors.black)
gpu.setResolution(width: 2 , height: 2, true)
print(" Welcome to Technopolis " )

term.setCursor(1,3)
gpu.setBackground(colors.brown)
gpu.setForeground(colors.blue)
print("     Info    Rules    Staff    ")

I use to program on computercraft back in 2013, but forgot a lot of stuff. I only got a small portion of the program but I don't know where to go from here.

I couldn't find any helpful tutorials and some of them are out of date.

components send signals, and the screens send touch events.

for more signal info read here: https://ocdoc.cil.li/component:signals

and you should run `dmesg` on the command line shell, which prints all signals the machine is getting. it can be quite helpful
