Placing a delay between key presses?

[BoopDeePoop]

I'm attempting to place delay between when you can press a certain key. I want it so that when you press the space bar, the key does what it's assigned to do, and in order for the game to take any more input from the space bar, you must wait x amount of seconds before it will actually press space again. I'm trying not to use any libraries for this so if someone could help that'd be great. Everytime I try nothing works.

Try a timer.

Code: Select all

local time = 0
local enabled = true

function love.update(dt)
time = math.max(0, time - dt)
if time <= 0 then enabled = true end
end

--when you do your keypress:
time = delay

Remember in the above example you'd also need to set enabled to false in the keypress, and you'd have to check if enabled == true before executing the keypress code.

I get main.lua 40: attempt to perform arithmetic on global "time" (nil value)

Here's my .Love

I usually always put variables into load(). Guess I shouldn't then. Still, the error is gone now but I'm still able to press the space bar as many times as I want.

Code: Select all

function control_list(key)

--Only affects game if in 'Playing' state
		if gamestate == "playing" then
	if enabled == true then
	if key == " " then
		time = 3
		enabled = false
		phrase = math.random(1,20)
		end
	end
end

--Only affects game if in 'Menu' state
		if gamestate == "menu" then
	end

--Only affects game if in 'Options' state
		if gamestate == "options" then
	end

--General Controls, work in any state.

	if key == "escape" then
		love.event.quit()
	end
	if key == "1" then
		gamestate = "menu"
	elseif key == "2" then
		gamestate = "playing"
	elseif key == "3" then
		gamestate = "options"
	elseif key == "4" then
		gamestate = "controls"
	end
end

You can, just don't declare them as local in love.load().

Thanks for the note! I'm still having a problem with the code though. I'm able to press the key as many times as I want without delay.

make time = 0 global ( by removing local), that should fix it
