pause menu example

function pause()
    tmp = screen.toimage() --first make a screenshot
    while true do --start the pause loop
        controls.read() --read the controls
        tmp:blit(0,0) --blit the tmp image
        -----------------Here your stuff
        -------If you want to use your own images, delete tmp = screen.toimage() and tmp:blit(0,0) and tmp:free()
        --if you want to return to the menu pressing triangle for example and the menu is main_menu() function:
            if controls.press("triangle") theen
                --first free the tmp image
                main_menu() --return to the main menu
            end
        --------------------------------
        if controls.press("start") or controls.press("circle") then
            break   --breaks this bucle so the game continues
        end
        screen.flip() --swap buffers
    end --end the puase loop
    tmp:free() --free the tmp image
end

--the while true do
while true do
controls.read()

if controsls.press("start") then    --when press start
    pause() --  Pause :)
end
if controls.select() then make_error() end-- This make an error so when luadev gets an error, it connects to usb,
                                --then you can update your code and if you press cross luadev will restart
                                -- and your code will be updasted without returning to the xmb
screen.flip()
end
