How do I make an image change when clicked?

[Kookerus]

I want to draw an image on the screen, and make it change to a different image when the user clicks on it. How would I do that?

There is a simple command that you can use statements for such a thing and it's called "switch"

so.

Code: Select all

switch variablename {
  A: do stuff  break;
  B: do stuff break;
}

so if clicked just switch the graphic^^

Basically you want to wait for a click (with mousereleased), check that you clicked on the original image, and replace it with your new one.

Code: Select all

function love.load(args)
	img = love.graphics.newImage("original.png")
end

function love.mousereleased(x, y, button)
	if x > 10 and x < 10 + img:getWidth() and
		y > 10 and y < 10 + img:getHeight() then
		img = love.graphics.newImage("clicked.png")
	end
end

function love.draw()
	love.graphics.draw(img, 10, 10)
end

Thank you so much! This works great!

you could emulate it with an

Code: Select all

if x then do this
elseif this then do this
else do this
end

statement, but that could get quite confusing
