Having been fed up of passing callbacks into functions I thought that there had to be a better way. Wouldnt it be useful for any object to be able to register listeners and dispatch events? now you can. :-) 1 2 3 4 5 6 require "lib-events" myClass={} cLibEvents:instrument(myclass) -- consumers of myclass can use addEventListener -- myclass can use dispatchEvent lib-events.lua 1 2...

Here is yet-another pausable transition library. I call it "ctrans", short for "custom transitions". It is different in that it keeps track of all transitions internally, rather than just tag on data to tween objects. This keeps the size of the tween objects small and allows you to perform actions on a large set of transitions with a simple command. More...

Hi I was trying to sequence the transition components of a complex grouping of objects. It was getting a real pain to have to coordinate callback functions. So I wrote a helper class to painlessly sequence the transitions. only one callback - the one called when its all finished enjoy! 1 2 3 4 -- VERSION -- -- This work is licensed under a Creative Commons Attribution-ShareAlike 3.0 Unported License. -- -- http://...

This is a really small library to add an event to the list of events fired by the storyboard api. I found that I wanted to have createScene fired on every gotoScene call simply to prepare the scene so it looked right prior transitioning onto the screen. Of course, this doesn't happen, so I created setScene in it's place. setScene will only fire when createScene is not fired, meaning it can safely be called from... More...

Accurate tempo/BPM-based timing in your animations and general beat-sequenced stuff. I am using this logic in a spiffy metronome that I am porting over to iOS using Corona. I've used this rock-solid tempo pulse logic in my music apps for various platforms since 1998 and it has never done me wrong. More...

For an app I am soon to release, I needed to allow the user to draw a series of squiggily lines with his or her finger, and to be able to reference or remove specific lines/strokes. The closest bit of code I could find online was actually provided by Carlos (https://developer.anscamobile.com/forum/2011/05/02/need-some-help), but I found that his solution of appending new points onto a single line got laggy the...

This code will create a variable running timer for your game/app. Please see below for what to set it up. Functions: clock.cancelTimers(): This will cancel or pause your timers clock.resumeTimers(): This will resume your timers from a clock.cancelTimer call First you have to require the clock by writing: 1 local clock = require("clock") Then to set up a clock you have to follow this: 1 2 3 4 5 6 7...

Previous example: https://developer.anscamobile.com/code/pinch-zoom-rotate [EDIT: If you take a closer look at the main.lua, I had recently added code to pinch-zoom a display group, instead of an image. This means that the group can have a lower quality image at smaller scales and a larger image (lazily loaded) at larger scales. While this could be handled in the pinch library, I thought it better - for now - to... More...

A common feature in a lot of games and applications is the use of a MessageBox to display some text to the user and provide then with different buttons to signify what action they want to take. Something like a "Do you want to Exit?" with a Yes and No button. I have posted source for the cMessageBox.lua module along with sample tests showing the features of this code. The code depends on the ui.lua module (... More...

dmc_dragdrop is a module which coordinates drag and drop operations in an application. It can be used to implement things like draggable shopping carts or even a vehicle configurator (e.g., engine, weapons, tires, etc). The module's functionality is based on that of the Adobe Flex Drag Manager, so if you've used that before, then the operation of dmc_dragdrop will be very familiar. Though the module is fully object-... More...

Update 8/10/11 - Now with more zoom! - Added tap detection. Double tap to zoom 2x, double tap again to return. Double tap from any scale to return to original scale. - Various tweaks. No longer jiggles with three fingers. Removing/replacing fingers behaves better. This is just a slight improvement of the Pinch Zoom example from the sample apps. It now supports one touch move and the zooming centers around where you... More...

A design pattern for doing finite state machines (FSMs) in Lua Finite state machines can be used to force (at least parts of) your code into deterministic behaviour. I wrote this code to implement generic graphical objects where the presentation and behaviour of the objects can be specified by using state-transition tables. This resulted in less code (and less bugs), a higher modularity and above all a reduction of... More...
