Having trouble with some computercraft/lua code -

-

hi want lua code in computercraft allow user turn redstone signal on/off right clicking on monitor on top, can't work.

monitor = peripheral.wrap("top") monitor.clear() monitor.settextcolor(colors.red) monitor.setcursorpos(1, 1) monitor.settextscale(1) monitor.write("hello")  function rubber()     monitor.setcursorpos(1, 2)     monitor.clearline()      if rs.getoutput("right", true)         monitor.write("rubber farm on")     elseif rs.getoutput("right", false)         monitor.write("rubber farm off")     end      local event = { os.pullevent() }      if event == "monitor_touch"         if rs.getoutput("right") == true             rs.setoutput("right", false)         else             rs.setoutput("right", true)         end     else         write("test")     end      rubber() end

right displays 'hello' , don't know how fix it, know how? i'm beginner @ lua i've made pretty simple mistakes. thanks

local event = { os.pullevent() } if event == "monitor_touch"

os.pullevent returns tuple. in code, you're packing tuple table. that's fine, compare table string. tables can't equal strings - they're table. either don't pack tuple table, , keep first return value (the type):

local event = os.pullevent() if event == "monitor_touch"

or extract first element when comparing

local event = { os.pullevent() } if event[1] == "monitor_touch"

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
