Parallax effect animation with TweenMax (part 2)

This is the second part (and most recent) of a parallax tutorial and animation using GSAP TweenMax. Before we begin a little bit of theory behind the parallax effect.

Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. The term is derived from the Greek παράλλαξις (parallaxis), meaning “alteration”. Nearby objects have a larger parallax than more distant objects when observed from different positions, so parallax can be used to determine distances.

Here’s an example of the final effect

Phonegap/Cordova read images from gallery folder [Tip]

Hello, recently I was working on a project where I wanted to get all the images from the camera but because I wanted to load them in batches I had to find their filenames and store them in a local array for future use.
Since the new cordova file plugin did some changes, there is little information on how to get directories and files.

So here is how it is done on Android (because Apple doesn’t allow access to public folders).

Phaser.io Modal creator

Recently as I was building a new game, I realized that one of the most re-used elements across a variety of games is the “modal”, whether it is a countdown, a message modal or a game-over modal.
So I thought to create a little snippet that would make creating a modal an easier task, with the following script we can create a large combination of either text, bitmaptext or images.
So enough with the presentation, lets see how it looks, in this codepen I created six examples for all tastes.

See the Pen Phaser Modals by Michael Dobekidis (@netgfx) on CodePen.

Nice huh?

So let’s see what this script can support.

Phaser.io how to use atlasHash to your advantage.

Lately I have been using Phaser.io as a game framework/engine. And one thing that is quite tedius, is to manage your Sprites and animation frames, it is roughly 40% of your game development time.

However there is one tool that now -that officially supports Phaser- cuts down this time at least by 90%.

View more info or download TexturePacker here: https://www.codeandweb.com/texturepacker

The tool is named TexturePacker and allows the load of all your assets and combines them very conveniently into a single Spritesheet and exports that Spritesheet along with a .json file that “tells” Phaser where to find each frame (based on coordinates on the spritesheet), this is called an atlasJSONHash/atlasJSONArray.

I have attached a video showcasing a very rough export that I will use to create today’s codepen example (see below).

Here is the end result of our game.

Simple SVG animation with Greensock DrawSVG-Plugin

I had some free time and thought to experiment a bit with the new DrawSVG plugin from Greensock, it is a plugin that animates the border of an SVG, other parts of the SVG like fill or opacity could already be tweened via TweenMax/Lite.

Here’s a quick tutorial to get you started and I hope you’ll forgive my lousy Illustrator skills…

See the Pen OPNOgM by Michael Dobekidis (@netgfx) on CodePen.

Add/Remove text from HTML using only CSS

This is a neat trick that recently came very handy as I wanted to change the text of a paragraph tag but only had access to the .css file of the page.

Heres what it looked like:

<p class="someclass">
   <a href="#">Some Link</a>
   "Some text embeded in the paragraph tag, oh my!"
</p>

Yes it was that bad. So here’s what I came up with (might be around for sometime now, but could not find something fast in google)

The CSS:

.someclass{
   color: rgba(0,0,0,0); /* to make inside text invisible */
   text-align: center;
   white-space: pre;
}

.someclass a {
   display: none;
}

.someclass:before {
   content: "Powered by Netgfx.com";
   color:#ffffff;
   text-align: center;
   font-weight: bold;
}

So what we did here was to make the existing text invisible by applying a color using rgba and setting the alpha to 0, and then add some new text with the css “content” attribute and the pseudo-selector :before/:after.

Problem solved!
