Button API

[mopet01 0]

Hello everybody

i guess i am wrong here, i moved it to support, programming 

Well, for the first let me tell you, i'm a bloody beginner in OC and lua, so i hope to get some help here 

I'm trying to modify a code for my world but when i do, i just get errors

So, please, can anybody help me to get this work....

The "buttonAPI" is the part in the background and the "aufzu" is the working part where the functions are told.

 

buttonApi.lua

local API = {}
local button={}

local component = require("component")
local colors = require("colors")
local term = require("term")
local mon = component.gpu
local w, h = mon.getResolution()
local Green = 0x00AA00
local Red = 0xAA0000
local Black = 0x000000

buttonStatus = nil

function API.clear()
  mon.setBackground(Black)
  mon.fill(1, 1, w, h, " ")
end

function API.clearTable()
  button = {}
  API.clear()
end
               
function API.setTable(name, func, xmin, xmax, ymin, ymax)
  button[name] = {}
  button[name]["func"] = func
  button[name]["active"] = false
  button[name]["xmin"] = xmin
  button[name]["ymin"] = ymin
  button[name]["xmax"] = xmax
  button[name]["ymax"] = ymax
end

function API.fill(text, color, bData)
  local yspot = math.floor((bData["ymin"] + bData["ymax"]) /2)
  local xspot = math.floor((bData["xmax"] + bData["xmin"] - string.len(text)) /2)+1
  local oldColor = mon.setBackground(color)
  mon.fill(bData["xmin"], bData["ymin"], (bData["xmax"]-bData["xmin"]+1), (bData["ymax"]-bData["ymin"]+1), " ")
  mon.set(xspot, yspot, text)
  mon.setBackground(oldColor)
end
     
function API.screen()
  local currColor
  for name,data in pairs(button) do
    local on = data["active"]
    if on == true then currColor = Green else currColor = Red end
    API.fill(name, currColor, data)
  end
end

function API.toggleButton(name)
  button[name]["active"] = not button[name]["active"]
  buttonStatus = button[name]["active"]
  API.screen()
end     

function API.flash(name,length)
  API.toggleButton(name)
  API.screen()
  os.sleep(length)
  API.toggleButton(name)
  API.screen()
end
                                             
function API.checkxy(x, y)
  for name, data in pairs(button) do
    if y>=data["ymin"] and  y <= data["ymax"] then
      if x>=data["xmin"] and x<= data["xmax"] then
        data["func"]()
          return true
      end
    end
  end
  return false
end
     
function API.heading(text)
  w, h = mon.getResolution()
  term.setCursor((w-string.len(text))/2+1, 1)
  term.write(text)
end
     
function API.label(w, h, text)
  term.setCursor(w, h)
  term.write(text)
end

return API

 

aufzu.lua:

API = require("buttonAPI")
local event = require("event")
local computer = require("computer")
local term = require("term")
local component = require("component")
local gpu = component.gpu

local rs = component.redstone
local colors = require("colors")
local side = require("sides")

function API.fillTable()
  API.setTable("Tor", tor, 10,20,3,5)  
  API.setTable("Bahn", bahn, 22,32,3,5)
  API.setTable("Raus", test3, 10,20,8,10)
  API.setTable("Rein", test4, 22,32,8,10)
  API.screen()
end

function getClick()
  local _, _, x, y = event.pull(1,touch)
  if x == nil or y == nil then
    local h, w = gpu.getResolution()
    gpu.set(h, w, ".")
    gpu.set(h, w, " ")
  else 
    API.checkxy(x,y)
  end
end

function tor()
  API.flash("Flash",0.01)
  rs.setBundledOutput(sides.back, colors.lime, 200)
  os.sleep(16)
  rs.setBundledOutput(sides.back, colors.lime, 0)
end

function bahn()
  API.toggleButton("Toggle")
  if buttonStatus == true then
  rs.setBundledOutput(sides.back, colors.red, 0)
    else
     rs.setBundledOutput(sides.back, colors.red, 200)
  end
end

function test3()
  API.flash("Flash")
  term.setCursor(1,25)
  term.write("Free Memory: "..computer.freeMemory().." bytes")
end

function test4()
  computer.shutdown(true)
end

term.setCursorBlink(false)
gpu.setResolution(80, 25)
API.clear()
API.fillTable()
API.heading("Was soll getan werden?")

while true do
  getClick()
end

 

When i click on the, for example, "tor", i just get errors and that is all i get

I also tried to give a redstone signal via lua, but here i also get an error, i don't know why.

Computer is a Tier 3 and the restone card inside is a Tier 2

 

Thank you in advice
