help please

so i want this to do something once a push the a key on my keyboard and the code i have.

here is my code


print("push 1")
local event, p1 = os.pullEvent()
if event == "key" and p1 == "30" then
print("HI")

The argument of the "key" event is a number, not a string. So it should be:

print("push 1")
local event, p1 = os.pullEvent()
if event == "key" and p1 == 30 then -- removed the quotes from the number
  print("hi")
end

Also, here's a list of the key codes, cause the code for 1 is not 30 is 2.

ik i

ik i change it to tets a different one and still did not work xD

oh here is what i wanted it for

term.setCursorPos(1,1)
term.clear()
print("push 1-6")
function main()
local event, p1 = os.pullEvent()
if event == "key" and p1 == 2 then – key 1
rs.setBundledOutput("bottom", colors.white)
sleep(1.0)
rs.setBundledOutput("bottom", rs.getBundledOutput("bottom") - colors.white)
sleep(0.20)
shell.run("next")
end – key 1
if event == "key" and p1 == 3 then
rs.setBundledOutput("bottom", colors.orange)
sleep(1.0)
rs.setBundledOutput("bottom", rs.getBundledOutput("bottom") - colors.orange)
sleep(0.20)
shell.run("next")
end – key 2
if event == "key" and p1 == 4 then
rs.setBundledOutput("bottom", colors.green)
sleep(1.0)
rs.setBundledOutput("bottom", rs.getBundledOutput("bottom") - colors.green)
sleep(0.20)
shell.run("next")
end – key 3
if event == "key" and p1 == 5 then
rs.setBundledOutput("bottom", colors.brown)
sleep(1.0)
rs.setBundledOutput("bottom", rs.getBundledOutput("bottom") - colors.brown)
sleep(0.20)
shell.run("next")
end – key 4
if event == "key" and p1 == 6 then
rs.setBundledOutput("bottom", colors.black)
sleep(1.0)
rs.setBundledOutput("bottom", rs.getBundledOutput("bottom") - colors.black)
sleep(0.20)
shell.run("next")
end – key 5
if event == "key" and p1 == 7 then
rs.setBundledOutput("bottom", colors.blue)
sleep(1.0)
rs.setBundledOutput("bottom", rs.getBundledOutput("bottom") - colors.blue)
sleep(0.20)
shell.run("next")
end – key 6
end
main()

Fixed use char in place of key

i don't know whether you are asking a question or making a statement?
every time you press a key on your keyboard there is two events . one is a "char" event then other is a "key" event.

the key is always a number but the char is always a character eg "c" or ")" or "1" basically the symbol on the keyboard is "char" and the key is a number eg 1 or 24 or 16. i find it easer to work with "char" events normal as they are more readable

But they work differently. Key returns a key code as the parameter, which is a number representing the key pressed. Enter is 208 I believe. Char returns an alphanumeric/symbolic character. I don't believe that key 1 corresponds with character 1 in any way (and 0 can't). So you'd need to figure out which key codes you actually wanted.

Char is better for ease of use when using alphanumerics.

some example coded and the corresponding key on keyboard

28 enter
200 up
208 down
203 left
205 right
74 -
78 +

His code is fine, it works and has the right key codes, he was just showing the finished code (Although there's some things that could be improved).
