This code hurts me, even looking in a small segment. I'm 12 and I know how to do this. Functions are a wonderful thing. As are loops besides for the "if" loop. Either way, I might as well help you. First, put all of your game inside ONE function. At the end of the function, add a yes/no prompt and a variable containing a boolean value. Said boolean should equal 0 if they typed "n" and 1 if it was "y" then, after the end of the function, call it. Then set up an if statement that will run the function or exit the program.
Example:
newGame==1
function main()
function game()
--Game Code here
end
game()
global newGame==0
print("New game? y/n")
io.read()
if io.read==("y") then newGame==1 elseif io.read==("n") then newGame==0 elseif not io.read==("y") and not read ("n") then print("Please enter y or n") end
end
function startGame()
if newGame==1 then main() elseif newGame==0 then end
end
startGame()
EDIT: The "read" should be "io.read". Fixed.
Nope, nope, nope, nope, nope!
Firstly, please don't revive the dead. Leave the topics to rest in peace.
Secondly, loops are a wonderful thing, but `if` statements are not one of them. Possible loops
--# while loop
while <condition> do
--# code to loop
end
--# repeat loop
repeat
--# code to loop
until <condition>
--# incremental for loop
for i = <start>, <end>, <optional increment> do
--# code to loop
end
--# generic for loop
for <key>, <value> in <iterable structure> do
--# code to loop
end
Thirdly, Lua has booleans, just use those instead of calling numbers a boolean.
Lastly, your program has problems.
newGame==1 --# this will be an error, you should have a single `=` there
function main()
--# why an anonymous function?
function game()
end
--# to then call it here, why not just do game code here?!
game()
--# there is no global keyword in Lua, I have the feeling you've come from Python? also again, wrong `=`
global newGame==0
print("New game? y/n")
--# you should use `read`, `io.read` uses `read` so just remove the need to perform that extra function call
--# you're not storing the value in a variable? o.O
io.read()
--# now you're checking a function pointer against a string
if io.read==("y") then
--# wrong `=`
newGame==1
--# again, checking function pointer... what language does this even work in?
elseif io.read==("n") then
--# wrong `=`
newGame==0
--# checking a function pointer, and then waiting for input from a user again.... actually the "n" would cause an error
elseif not io.read==("y") and not read ("n") then
print("Please enter y or n")
end
end
function startGame()
if newGame==1 then
main()
--# no need for this
elseif newGame==0 then
end
end
startGame()
Your code fixed…
local running = true
function game()
--# game code here
end
function main()
game()
print("New game? y/n")
local input = read():lower()
while input ~= "y" or input == "n" do
print("Please enter y or n")
input = read():lower()
end
running = input == "y"
end
function startGame()
while running do
main()
end
end
startGame()
The best (and most commonly used) code structure for a game…
local quitRequested = false
local function update()
--# increment any variables and such
end
local function render()
--# render any changes that have been made
end
local function processInput()
os.startTimer(0.1) --# allows the game to move on and not get stuck here.
local e = os.pullEventRaw()
--# process the event that was received
if e[1] == "key" and e[2] == keys.q then
quitRequested = true
end
end
local function main()
render()
repeat
processInput()
update()
render()
until quitRequested
end
main()
