How Mix Love.Draw and Love.Update?

[Krizzu]

Hello

I got problem. I want to make a information about leaving the game.

So, When I press Escape Key (in love.keypressed function) I want to print in the middle of the screen text "Are you sure want to quit"(love.draw)

Code: Select all

function love.keypressed(key)  
   if key == "escape" then
		love.event.quit()
   end
end

anyone know how to make it?

You can do this by having a variable to hold the state the game is in.

It can be set first in love.load.

Code: Select all

function love.load()
	state = 'play'
end

If the state is 'play' and the escape key is pressed, you can then set the state to something else, e.g. 'quitting'.

And if the state is 'quitting' and some special key is pressed (like y for yes), then the game can quit.

And if the state is 'quitting' and some other key was pressed, then the state can change back to 'play'.

Code: Select all

function love.keypressed(key)
	if state == 'play' then
		if key == 'escape' then
			print('this happens?')
			state = 'quitting'
		end
	elseif state == 'quitting' then
		if key == 'y' then
			love.event.quit()
		else
			state = 'play'
		end
	end
end

What is drawn in love.draw can be changed depending on the state.

Code: Select all

function love.draw()
	love.graphics.print('Testing! The state is '..state, 10, 10)

	if state == 'quitting' then
		love.graphics.print('Are you sure you want to quit? (press "y" to quit)', 250, 250)
	end
end

A .love file is attached with this example.

I hope this helps!
