Radial Buttons

Wiki for Radial Menus

Example radial menu code.

diallib, arcButton = require("ui.dial")()
p = require("nprint")
function love.load()
        -- first set the dial.  This provides a central way to reposition buttons on a dial.
	dial = diallib.new(400, 400, 300)

	local last = 0
	for i = 1, 6 do -- loop to make 6 equally sized arc buttons
		arcButton.new(dial, last, last + math.pi/3)
		local t = dial.buttons[#dial.buttons] -- dial.buttons is set within the library
		t:setText(string.rep(i, 4), true) -- fast way to set text.  See main wiki for more info.
		function t:onRelease() -- how to set a released mouse custom function
			print(t.text)
		end
		function t:onEnter() -- Callback when the cursor enters the bounding box of button
			t:setColor({math.random(), math.random(), math.random(), 1}, true)
		end
		last = last + math.pi/3
	end
end

-- the rest are standard Love2d functions.  See uisets to learn more about how to bundle multiple buttons together.
function love.update(dt)
	dial:update(dt)
end
function love.draw()
	dial:draw()
end

function love.mousepressed(x, y, button, istouch, presses)
	dial:mousepressed(x, y, button)
end
function love.mousereleased(x, y, button)
	dial:mousereleased(x, y, button)
end
