Tuto tiny-ecs beatemup Part 3 transitions menu options
From GiderosMobile
We quickly go through the Transitions Class, the Menu scene and the Options scene as they were covered in the Gideros Game Template1 Tutorial and we are only getting started ;-)
the transitions.lua file
The transitions Class controls all scenes transitions. It plays an essential role in the flow of the game. I put the code here in case it is different from the Gideros Game Template1.
The code:
Transitions = Core.class(Sprite)
function Transitions:init(xnextscene)
self.nextscene = xnextscene
-- a movieclip for transitions (you can change it to anything you want!)
local pixel = Pixel.new(g_ui_theme.pixelcolorup, 1, myappwidth, myappheight)
local mc = MovieClip.new{{ -- you choose the duration, the effects, ...
1, 50, pixel, -- duration: 64, 32
{
y = { 0, myappheight, tweens[31] }, -- tweens[math.random(#tweens)]
alpha = { 1, 0, tweens[19] }, -- tweens[math.random(#tweens)]
}
}}
mc:play() -- play only once
-- position
mc:setPosition(myappleft, myapptop) -- for mobile
-- order
self:addChild(mc)
-- listeners
mc:addEventListener(Event.COMPLETE, function()
self:gotoScene(self.nextscene)
end)
-- let's go
-- self:myKeysPressed() -- optional
end
-- cut the transition (optional)
function Transitions:myKeysPressed()
self:addEventListener(Event.KEY_DOWN, function(e)
if e.keyCode == KeyCode.ESC or e.keyCode == KeyCode.ENTER or
e.keyCode == KeyCode.SPACE or e.keyCode == g_keyaction1 then
self:gotoScene(self.nextscene)
end
end)
end
-- scenes navigation
function Transitions:gotoScene(xnextscene)
-- unload current assets
stage:removeAllListeners()
for i = stage:getNumChildren(), 1, -1 do
stage:getChildAt(i):removeAllListeners()
stage:removeChildAt(i)
end collectgarbage()
-- load next scene (eg.: Menu.new())
stage:addChild(xnextscene)
end
transitions.lua Code comments
The transitions Class takes 1 argument, that is the next scene to be loaded.
There is one MovieClip which plays a fade animation. Feel free to change it to anything you like.
When the fading animation is done, all the previous Sprites and eventual listeners are removed from memory and the new scene is added to the stage.
In the main.lua file is the last file to be loaded when launching the game.
This is where I like to set up the windows, put global functions and start the game:
- the windows parameters (title, position, ...)
- the global app functions to load and save user's preferences to disk
- some global variables specific to the game
- start the game (transition to the menu scene)

main.lua Code comments
The global prefs functions are used to save the user's preferences like key remapping, sound volume and difficulty.
Before the game is launched, the app reads the file and sets the stored values. If there is no file preferences yet, we set the preferences with initial default values.
The switchToScene function is used to switch between scenes. It unloads the previous scene and transitions to the new one.
Then there are some global variables specific to the game: all the animations for our actors (g_ANIM_DEFAULT, g_ANIM_IDLE_R, ...). The _R suffix indicates our sprites are facing Right. Here we only need right facing animations but you may easily add left animations with an _L suffix.
Finally we start the app with a logo transitioning to the Menu scene.
