This is a nice solution for a problem occured when making strategy games or wireframe applications. Or generally when we want to select multiple items and have them in a visible group.
It is a rather simple solution once the math make sense.
Here’s a nice example I made on codepen. Simply click and drag to form a rectangle around one or both of the objects.

I have been struggling with the lack of replay procedures in HTML5 gaming, with flash things were quite easy because we could save all of our game sessions as movies or swf files that could be later on viewed. With HTML5 we don’t quite have that, or it is not as easy. So I was thinking of ways to produce movies from canvas.
And then it hit me… images can produced as urls and canvas can be exported as an image, and what are continuously changing images? A movie!
So I went on and made a codepen about this. And quite frankly it kinda looks awesome. Of course some more brilliant minds than mine could dig into this and help me make it truly useful for all.
So let’s see the pen first. The procedure is as follows:
We click record and move the box around
Then we stop and we watch the movie that was produced.

Hello all, so I have been pretty active on the “create games” front but not so much for blogging, sorry about that… So I come to you now with a Pen that razed over 1500+ views on codepen and 14 hearts so far…
It’s my implementation of a remote collision detection system that uses degrees instead of bounding boxes. This works well for games where you want to calculate the position of the shoot but the “cannon/lazer/fazer/tower” is not near the target, so instead of creating long bounding-boxes. We just calculate the degrees between the source (cannon) and the target(enemy). And when the cannon is rotated on those degrees it can fire.
Here I will show how a tank can “detect” the enemy. Here’s a quick example and the code will follow:

Classic hangman game with a plot twist
Dictionary with over 1800 words
Supports themes, and theme creation
Includes two themes ( blackboard and notepad )
Adaptive design that manages size in different devices
Included video help file for changing Theme
Check how easy it is to change themes:
So I was building a new game and wanted to include some sounds and an ambient sound as background music. So I bought a sound from Envato Audio Jungle, and also I asked my cousin to make me an ambient/sci-fi/space sound… He came up with a rather nice composition for a space game.
This is how I did it:
Hello, I just released a grid pattern constructor on Envato Codecanyon. This Grid-pattern is ideal for wireframe templates, blueprint designs or as a simple background.
The grid contains a build-in mechanism for responsive re-draw, and can be easily customized to include other grid-patterns, right now it can produce: blocks, diamonds, hexagons, circles and diagonal lines
You can find it here: Canvas Multi-Grid
Hello once again, this time I will show a nice technique to create exploding particles with KineticJS.
First of all we setup the stage and the canvas objects.

This is a simple tip of how to create a zoom to point effect with kineticjs and mousewheel event.
So lets say that you want to zoom into a specific point on a canvas, of course you have used the excellent kineticjs framework, well then you are in luck.
To begin with this is the end-result for all the “quick-fix” people out there.

The rest… come along…
