I already showed you two ways of editing Box2D environments with Bison Kick and simply using the Flash IDE. Today I’ll show you the most advanced editor at the moment: World Construction Kit made with Box2D C++ 2D physics engine compiled with Adobe Alchemy. The demos on the official site are really awesome and the [...]

Some time ago I published a Basic Box2D editor using Flash movieclips. Now it’s time to show you something way more interesting called Bison Kick by Jacob Schatz who runs the blog jacobschatz.com (bookmark it! It contains a lot of useful information). It’s an online Box2D editor with live preview. Besides it’s still under development, [...]

When you are about to design a level or whatever else in Box2D, you have to face some design issues due to different unit measurements (Flash works with pixels while Box2D uses meters) and the common problems in level design: the need to have a WYSIWYG interface. Some frameworks such as Citrus Engine, have a [...]

We are about to create an intelligent camera that will follow a body in Box2D. What’s the difference between an intelligent camera and a dumb one? Simple… the intelligent camera follows the object keeping it in the middle of the screen as long as there are enough game area to fill the screen. The dumb [...]

If you want to make a good game, a good camera movement is necessary. This time we’ll learn to follow a Box2D object with the camera. Box2D does not have a “camera”, so we will have to move the stage according to body position. This is the same script as Real world catapult using Box2D [...]

If you want to read an interesting article about Flash games and physics, I suggest you to point your browser on Developing physics-based games with Adobe Flash Professional by Samuel Asher Rivello. I was quoted in the article, but what makes it really great is the way it will guide you through the creation of [...]

We got it. After the first catapult prototype and the “slippery wheels” sequel, this is a version with realistic movement and a lot cleaner code. To add realistic movement I defined friction and restitution, making useless the CreateFixture2 function and widely using the more appropriate CreateFixture one. This way I have full control on fixtures, [...]

Did you enjoy the catapult prototype? Here I am with the second part, adding wheels controlled by left and right arrows. Have a look: Now you can move the catapult with left and arrow keys, and shoot with a mouse click If you feel the catapult is running on an icy surface, that’s because I [...]

This is an early attempt to simulate a real world catapult using Box2D. Raw and uncommented code, but a lot of useful information about compound objects, revolute joints and motors. This is what you’ll get: Click with the mouse to shoot the ball.

Ok, it’s not an april fool… the bulgarian freelancer Krasimir Tsonev really made a Box2D based RPG game called The Big Adventure. And he also built the official game site with all features it needs to attract players: a community, a forum, a ladder, updated news… really a good job. Now he wants to share [...]
