Mario Style "Star" Effect

Posted by naveen_pcs, Posted on April 20, 2013

This will make an effect where your screen will flash through random colours like when you have a Star in Mario. The effect will cover the entire screen and it's self contained in a single lua file. All cleanup will automatically be done after the animation is finished (or if you end it early by calling stop() - see below for more details)

Require the module:

local rainbowScreen = require("rainbowscreen")

Then when you want to use it:

rainbowScreen.new({duration = 300, colorChangeTime = 150, screenCoverAlpha = 0.25})

Easy setFillColor Transition

Posted by bfintal, Posted on April 16, 2013

Here're 2 small self-contained functions you can use to perform a smooth transition for fillcolors:

Usage:

Initially set a fill color via: (We need this so that we can know what the color to transition FROM is)

1 2	local g = display.newRect(0, 0, 100, 100) setFillColor(78, 186, 248)

Then just call the set fill color transition via:

1 2	-- sets the color of 'g' to {255, 128, 0} for 3000 milliseconds setFillColorTransition(g, 255, 128, 0, 3000)

Transition Manager

The Transtion Manager was developed for transitions could be paused and resumed

Usage example:

local TransitionManager = require 'TranstionManager'
local isPaused = false
 
local transitionManager = TransitionManager.new()
 
local circle = display.newCircle(100,100, 40)
local rect = display.newRect(10,10, 40, 40)
 
local function pause()
    if isPaused then
        isPaused = false
        transitionManager:resume()
    else
        isPaused = true
        transitionManager:pause()
    end
end
 
Runtime:addEventListener('tap', pause)

Improved Transition Function Calls

I thought the current Corona transition methods are not exactly very customizable and has limited animation easings.

Furthermore:
1) You can't pause it easily. No pause ALL transition function either
2) There's a bug in the transition.from() method call if you enable delta = true

Solution:
I'll code the entire transition API from scratch. Using equations courtesy of Robert Penner that can be found at: http://www.robertpenner.com/easing/ , I've coded a brand new transition call.

Stuff to note:
1. Fixed the bug in the transition.from() call with delta enabled.

Color Transition Wrapper

Posted by atoko, Posted on May 9, 2012

Since changing color smoothly seems like a task that pops up often during game development, I decided to make a wrapper function (around Corona's default transition.to) in order to make it easier.

TO USE :
First load the table that contains the function:

1 cTrans = require("colortransition")

Then call the wrapper function as such:

cTrans:colorTransition(displayObject, colorFrom, colorTo, [time], [delay], [easing]) ;

i.e.

cTrans:colorTransition(rect, {255,255,255} , {0,0,0}, 500)

Animated Number Ticker

Posted by bryan.vaccaro, Posted on December 13, 2011

I wrote this snippet as a proof of concept for a score/time keeper in a game I'm currently working on.

The createTicker() function takes two parameters: a number, and the number of digits you want the display to be. It then generates a 'card' for each digit, based on the width and height of the number font + padding.

Pausable Transitions - A very simple method

https://github.com/SatheeshJM/simple_transition_pausing_from_Satheesh

Yeah I know there are a lot of transition managers.. Still never hurts to share code.. So here goes.

USAGE :

1
2
3

transition.to(object,params}
transition.pause(object)    
transition.resume(object)

I am not sure about the efficiency of this module. So if anyone has any modifications or if anyone finds any bug, please comment below.

And I haven't tested this completely, but till now, it has worked fine for me :)

Sequence.lua - Transition Execution order

Posted by calledpaul, Posted on October 17, 2011

Hello everybody!

I am a bit new to Corona but i am working on a game template. Below you can find the class i wrote to handle sequential animations (function calls). It's really easy but i think it will be helpful for somebody here.
My idea is to integrate it with TransitionManager somehow, but still havent stated with that, if somebody has any ideas about it i will be glad to here them.
PS: I think methods like stopTransitions and pauseTransitions should be implemented here.

Any feedback or improvements will be appreciated!

Easing library for Corona

Posted by loghound, Posted on May 14, 2011

I've really learned a lot from many of the libraries and code samples shared in the forum (I'm looking at you crawl space games!)

I thought I would add my modest contribution -- a library of additional eases/transitions/tweens for corona.

You can find it here

https://github.com/loghound/Corona-Transitions

To use simpley replace 'transition' variable with one from the library.
