CSS Playtime

I wanted to get some practice with CSS and Sass and learn CSS animations, so I started fiddling around in a gihub repo. I didn’t set out to create anything specific but wound up making a simple JavaScript animation engine that cycles through a list of objects representing a series of animations, initializing each one on a timer. I made a jQuery and a vanilla JavaScript version. This plunker uses the vanilla version:

Please forgive the ugly nature of this animation. I am not a designer so I decided not to spend time making it look good. I have a lot of experience matching the designs that other people come up with, but designing myself is not my strong-suit.

This engine would work for an animated banner, allowing you to pull in all the important data for the animation in a simple JavaScript object or JSON string. All you would need are your CSS animations.

I made a couple of my own CSS animations, but many of them came from animate.css, though I did change the ‘tada’ animation so that it utilizes Sass preprocessing to handle vendor prefixes a little better. I didn’t bother making this change to all the animations, since I already learned the things I was shooting for.

Frustratingly, Sass does not support interpolation on @import directives. Otherwise I would have set it up to iterate through a list of only the animations we wanted so we I could set up all the vendor prefixes for them in one loop. We could have a big Sass file with tons of animations but the final CSS file would only contain the ones we actually want. Instead, I will need to use a preprocessor mixin like Bourbon or Compass if I ever use this in the real world.

PDF Creation Station v4.0

In October and November of 2014, I had some time to work on my own personal projects, so I returned to my WordPress plugin Kalin’s PDF Creation Station. You can see the older version in an older post. I have rewritten the client side to use Angular.js and Bootstrap, almost entirely eliminating jQuery from the equation, and added a couple new features such as widget and custom menu support, a new sorting and pagination system for the lists of available posts and generated files, and the ability to generate .txt and .html files.

You can see the plugin in the WordPress.org plugin section. Or you can look at a more up-to-date version of the code on github.

Here’s a little instructional video I made for the tool page.

You can also see a video for the settings page, which is a different set of PDF features that allows you to put a link on every page to a PDF of that page.

And here’s some screenshots:

Accretive Tech, Streamate.com

streamateFlashUserClient

Our main user-facing Flash client.

From August 2011 to July 2014 I worked for Accretive Technology Group, maintaining their flagship product, a live streaming adult entertainment platform, duplicated over 1500+ websites. I started as a Flash ActionScript developer, maintaining and adding features to their performer client, of which I don’t have any screenshots, as well as the user client shown in this first image.

You can also see the user client by going to Streamate.com in a desktop browser and clicking on any performer. Warning: this is an NSFW site. The screenshots on this page are from the non-nude section.

Within the first year I worked with one other developer to convert our Flash user client into a mobile client for use on the few Android phones that supported Flash. Unfortunately I don’t have one of those phones so I don’t have a screenshot of that either.

streamateMobileHorizontal

Horizontal version of our mobile client shown on a phone.

After about a year I moved over to developing the model portion of the MVC framework for an HTML5 client designed for use on iPad, iPhone and other mobile devices. We focused on iOS because Apple users spend more money, but made sure everything worked on various Android devices as well. We built the app in jQuery and Spine.js, which is an MVC JavaScript framework similar to Backbone.js. I also wrote about 70 unit tests in QUnit and for future maintenance, had to learn a bit of Sass.

streamateMobileVertical

Vertical version of our mobile client shown on a phone.

Shortly after we finished this we began converting it for use in a couple different parts of our TV station.

After we finished the TV station, we moved on to building a redesigned Streamate. I took charge of converting the Flash client to the new design, then moved on to random tasks throughout the refactoring of our code.

In the end, I was doing mostly maintenance, bug hunting and adding small features all over the site, my time split between ActionScript, JavaScript, HTML, PHP and CSS. I finally decided to resign because it was getting to the point where I wanted to work on something different and wanted to take a break from development for a few months.

Wacky Words Facebook MMO

This is a funny word massive multiplayer role playing game built on Flash Builder and Google App Engine. Create funny combinations of words from random choices, then write out a description and try to sell your idea to investors. The more ridiculous the better. Gain cash as you get votes and investors, gain levels and buy skills. My future plans were to be able to buy naughty words, upload videos and images to  further illustrate your concept or start rivalries with other players or friends.

I never finished the project and since I stopped working on this project, Google App Engine removed support for Python versions below 2.7, so my app stopped working. It would take a bit of work to migrate this project to 2.7 and if I ever return to this I want to re-do it in AngularJS anyway so I decided to focus on other projects.

Even though it doesn’t work, and the folders are still a bit disorganized, you can still see the code on github: https://github.com/kalinr/Wacky-Words-Facebook-MMO.

AS2 Slot Machine Number Scroll Class

Here is an AS2 class that allows you to easily create and animate a slot machine style number scroller with two simple function calls. You can scroll numbers up or down by any increment, stopping and starting on any number. It contains many options using an optional greensock-style vars object. You can fine-tune animation speeds and heights individually for each character, or set a delay or onComplete function. Requires the GreenSock tweening engine.

Here’s an example. Note you can style or move the characters around on the stage virtually any way you’d like.

Get Adobe Flash player

Download class file and FLA. Note: the SWF will work, but you will need to download greensock for the FLA to publish correctly.

And here is the class itself, comments and everything.

/**

* VERSION: 1.0

* DATE: 2011-01-18

* AS2

* AUTHOR: Kalin Ringkvist

**/

import com.greensock.TweenLite;

import com.greensock.easing.Sine;

import mx.utils.Delegate;

import com.greensock.plugins.TweenPlugin;

import com.greensock.plugins.BlurFilterPlugin;

/**

* 	NumberScroll is a class designed to conveniently scroll a series of numbers up and down, as in a slot machine or price countdown animation

*

*

* 	To use this class, first create several movieClips, one for each digit in the number you wish to animate, each containing a textField named 'txt'.

*	If you want to scroll from 1 up to 999, or from 200 down to 10, you would place three movieClips on the stage. These movieClips can be identical or

*	different from each other, and can contain other content, just as long as they contain a textField named 'txt'. Be sure the textFields also have the

*	font properly embedded to show numbers.

*

*	Next, create the NumberScroll object, passing in an array containing your movieClips, and an optional vars object to set options.

*	Then, call startScroll(), along with the same optional vars object to begin the number scrolling

*

*	<b>EXAMPLE:</b><br /><br /><code>

*	import com.NumberScroll;

*

*	//create the NumberScroll object, passing in an array of movieClips that each contain a textField named 'txt'. In this case, the movieClips are all inside a movieClip called 'numbers'.

*	//the second paramater (1), sets the starting value

*	var ns = new NumberScroll([numbers.txt1, numbers.txt2, numbers.txt3, numbers.txt4, numbers.txt5], 1);

*

*	//start the scrolling. The object parameter is optional, but in this example, we use it to set the end value to 40, delay 2 seconds before beginning, set background textFields to %30 opacity,

*	//set delay of .4 of a second between each iteration, call scroll99() upon animation completion, count by 1,

*	//set animation height for each individual clip to 80, 80, 60, 40 and 20 pixels, and set the animation duration to 2 seconds, 1 second, 1 second, .8 of a second and .4 of a second

*	ns.startScroll({endNum:40, delay:2, backgroundTextAlpha:30, incrementDelay:.4, onComplete:scroll99, increment:1, animHeight:[80, 80, 60, 40, 20], animDuration:[2, 1, 1, .8, .4]});

Game Landing Page

Here’s a link to a landing page I built with JQuery and CSS for Big Fish Games. Click on the large buttons to select a game to load over the video in the main Flash div. The list of related games at the bottom as well as the ‘try it’ link will update accordingly. I used JQuery’s animation function for the opening drawer, browser scrolling, and the animated glow.

Below is one of the many Flash banner ads I built using the AS2 GreenSock tweening engine that linked to this landing page.

PDF Creation Station WordPress Plugin

This WordPress plugin allows you to build highly customizable PDF documents from any combination of pages and posts, or add a link to any post to download a PDF of that post. The UI is written in JQuery, the backend uses the open-source PHP library, TCPDF, for PDF generation. For source code, more info or screenshots, visit the PDF Creation Station download page at WordPress.org. You can also search for it in your WordPress admin’s plugin repository.

This image is of the settings page that allows you to customize the PDF and the link that is automatically displayed on every post.

Not pictured is the Tool page, with many similar options, that allows you to compile numerous different pages and posts into a single, highly customized PDF archive. Also not shown is the HTML insert fields and the list of 20 shortcodes you can use to insert headers or other post data.

You may also want to check out a PDF generated by Kalin’s PDF Creation Station. This one is this entire blog up until this point.

Kalin’s Post List WordPress Plugin

This WordPress plugin creates a shortcode, PHP snippet, or widget for placing highly customizable lists of posts, pages, or attachments into your post content or theme, built in PHP and JQuery. To look at the source code or get more information, go to the download page on WordPress.org, or search for it in your WordPress admin’s plugin repository.

You can see this plugin in use in the right sidebar of KalinFlash.com. You may notice when rolling over the items in the “Recent Additions” widget, you’ll get the post excerpt as a tooltip, which can’t be done with the regular recent posts widget. The “All Portfolio Entries” is another example of this plugin’s widget feature. There are many options for which posts to show, and you can write your own HTML, CSS, and even JavaScript, totally customizing the display of the lists.

Here’s another example, using the shortcode feature instead of a widget. This is a dropdown list of every portfolio entry on this site, organized alphabetically by title instead of chronologically. You could even get crazy if you wanted to and show the post excerpt whenever an item is selected.

Another example of this plugin exists on every portfolio entry, at the top, where it displays “year”, “technologies” and “involvement”. These three items are custom fields applied to the posts. Technically this isn’t a list. This is an example of Post List set to “none” mode, where all the internal shortcodes refer to the current post instead of the items in the list.

And here’s a screenshot of the main shortcode creation page:

Screenshot of Kalin's Post List settings page

Here’s another example, a CSS based table that displays all posts from the “Flash” category in a random order.

Easy Edit Links WordPress Plugin

 

This is the section created on the page/post edit screen

This is a simple WordPress Plugin written with PHP and JQuery that adds a convenient little box to your page/post edit screen that contains a list of all pages, posts, tags, categories and links, with edit buttons for each and a link to the actual live page for easy copying and pasting (Google Chrome and Safari users can even drag and drop). This plugin contains a self-caching feature so that the HTML code does not need to be recompiled every time the box is displayed, making it surprisingly light-weight.

For more information, or to get the source code, visit Kalin’s Easy Edit Links Download page at WordPress.org, or search for it in the plugin repository of your WordPress admin.

Here’s a screenshot of a portion of the settings page, giving you the ability to drag-and-drop to reorder items along with some other options regarding what to display.

AS3 Character Text Effect Class

This is a class I built in 2008 to animate any textfield, character by character. All you have to do is create a textfield, enter the text you wish to animate, then pass that into the class and it will make a nearly exact duplicate of the textfield, with each individual character in its own movieclip, then animate them in or out based on different parameters. It includes a dozen or so animation options. Go ahead and download the source and feel free to use this code wherever you like.
