Description

An easy way to manage scenes.

require "scenemanager"

Note: works in pair with the Easing plugin

Example

How to declare and change scenes in your main.lua file

require "scenemanager"
require "easing"

scenemanager = SceneManager.new(
	{
		["menu"] = Menu,
		["level01"] = Level01,
	}
)
stage:addChild(scenemanager)
-- from app start to menu
scenemanager:changeScene("menu")
-- from menu to level01
--scenemanager:changeScene("level01", 1, SceneManager.moveFromRight, easing.outBack)

Below you will find what a scene class looks like.

The Bare Bone of a Scene Class

Level01 = Core.class(Sprite)

function Level01:init()
	-- BG
	application:setBackgroundColor(0x1234AA)

	-- LISTENERS
	self:addEventListener("enterBegin", self.onTransitionInBegin, self)
	self:addEventListener("enterEnd", self.onTransitionInEnd, self)
	self:addEventListener("exitBegin", self.onTransitionOutBegin, self)
	self:addEventListener("exitEnd", self.onTransitionOutEnd, self)
end

-- GAME LOOP
function Level01:onEnterFrame(e)
end

-- EVENT LISTENERS
function Level01:onTransitionInBegin()
	self:addEventListener(Event.ENTER_FRAME, self.onEnterFrame, self)
end

function Level01:onTransitionInEnd()
	self:myKeysPressed()
end

function Level01:onTransitionOutBegin()
	self:removeEventListener(Event.ENTER_FRAME, self.onEnterFrame, self)
end

function Level01:onTransitionOutEnd()
end

-- KEYS HANDLER
function Level01:myKeysPressed()
	self:addEventListener(Event.KEY_DOWN, function(e)
		-- for mobiles and desktops
		if e.keyCode == KeyCode.BACK or e.keyCode == KeyCode.ESC then
			scenemanager:changeScene("menu", 1, transitions[2], easing.outBack)
		end
	end)
end

A table of all transitions

transitions = {
	SceneManager.moveFromRight, -- 1
	SceneManager.moveFromLeft, -- 2
	SceneManager.moveFromBottom, -- 3
	SceneManager.moveFromTop, -- 4
	SceneManager.moveFromRightWithFade, -- 5
	SceneManager.moveFromLeftWithFade, -- 6
	SceneManager.moveFromBottomWithFade, -- 7
	SceneManager.moveFromTopWithFade, -- 8
	SceneManager.overFromRight, -- 9
	SceneManager.overFromLeft, -- 10
	SceneManager.overFromBottom, -- 11
	SceneManager.overFromTop, -- 12
	SceneManager.overFromRightWithFade, -- 13
	SceneManager.overFromLeftWithFade, -- 14
	SceneManager.overFromBottomWithFade, -- 15
	SceneManager.overFromTopWithFade, -- 16
	SceneManager.fade, -- 17
	SceneManager.crossFade, -- 18
	SceneManager.flip, -- 19
	SceneManager.flipWithFade, -- 20
	SceneManager.flipWithShade, -- 21
}
