How to scale like this and keep my love.mousepressed to work. when i click on the start(is an image button) button it dont work.but when i remove the love.graphics.scale() it works. but i want to keep the love.graphics.scale(). it works great on mobile

state = "menu"

start_button = love.graphics.newImage("start.png")
dx = 228
dy = 398

image_height = start_button:getHeight()
image_width = start_button:getWidth()

scalex = 795
scaley = 720

window_width = love.graphics.getWidth()
window_height = love.graphics.getHeight()

function love.load()

end

function love.draw()

love.graphics.scale(window_width /scalex,window_height / scaley)
if state =="play" then
love.graphics.print("The Game Has Started",200,200)
end
if state =="menu" then
love.graphics.draw(start_button,dx,dy)
end

end

function love.mousepressed(x,y,button)

if x > dx and x < dx + image_width and y > dy and y < dy + image_height then
state = "play"
end

end

When doing a scaling operation your coordinates and dimensions of the input image scale as well. In your case the point in rectangle calculation is wrong, because you scaled dx, dy and the image dimensions by using love.graphics.scale.

In order to obtain the correct values you would need to scale dx, dy and the dimensions, too.

Code: Select all

local dsx = dx * (window_width /scalex)

Like that for all the other values.

can you show me an example bro?

Code: Select all

function love.mousepressed(x,y,button)
	--getting the scale factor
	local sx = window_width /scalex
	local sy = window_height / scaley
	
	--corrected translation according to scale
	local dsx = dx * sx
	local dsy = dy * sy
	--new image boundaries
	local iw = image_width * sx
	local ih = image_height * sy
	
	if x > dsx and x < dsx + iw and y > dsy and y < dsy + ih then
		state = "play"
	end 
end

Depends on what your goal is you might need to structure your code accordingly.
