guys how to use wait() 
Where did you get that idea that this exists in the first place?
You probably mean: love.timer.sleep( s )

Alternatively, if you mean the wait command from unix or C, I guess one way to do it is to spawn a thread, let the thread do anything that is needed (system calls or otherwise) and wait for it send a corresponding message back via channels. The love.thread page on the wiki has a simple example.

also, don't use love.timer.sleep for waiting unless you want to block all processing... and usually that's not what you want.
learn about timers and use those.

Code: Select all
function love.update (dt)
if waiting then
waiting = waiting - dt
if waiting < 0 then waiting = nil end
else
-- your update code
-- set "waiting = 3" here to wait 3 seconds to next updating:
if need_wait_3_seconds then
waiting = 3
end
end
endCode: Select all
function love.keypressed(key, scancode, isrepeat)
if key == "space" then
waiting = 3
end

I wonder if you're talking about the function in hump.timer. If that's the case, you need to create a function with the code that must do the wait, and call timer.update from love.update, like this:
Code: Select all
local timer = require 'hump.timer'
local text = nil
local font = love.graphics.setNewFont(40)
timer.script(function (wait)
text = "Hello"
wait(1)
text = "World"
wait(1)
text = nil
end)
function love.update(dt)
timer.update(dt)
end
function love.draw()
if text ~= nil then
love.graphics.print(text)
end
end
