Prerequisites This is the second part to a four part series about simulating a soft body physics in Box2d. Before continuing, you should read and understand the following two tutorials. 1. Quick Tip: Mixing OpenGL and Cocos2d (Triangle Fan) 2. Soft Body Physics with Box2d and Cocos2d Part 1/4 We will be using OpenGL to … [READ THE FULL ARTICLE]
Rigid Body and Soft Body Physics This is the first of a 4 part series which will show you how to simulate a simple soft body physics object in Box2d. We will be attempting to draw a fully texture mapped, squishy object. In part 1, I will be constructing the physics object. Box2d is a … [READ THE FULL ARTICLE]
Cocos2d and OpenGL Cocos2d hides most of the complexities of OpenGL, but every now and then you will be forced to write some custom OpenGL code. You can override the draw method of CCNode to perform your custom OpenGL drawing. You don’t have to write the code for scaling, rotating or translating inside the draw … [READ THE FULL ARTICLE]
Tip: Quick tip to swap out the image of a sprite that has already been initialized with an image. CCSprite *sprite = [CCSprite spriteWithSpriteFrameName@"oldImage.png"]; [sprite setDisplayFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"newImage.png"]];
To Collide or Not to Collide When you create simple Box2d objects, they will collide with each other. But what if you do not want an object colliding with all other objects? What if you want certain objects colliding with only certain other objects? How do we achieve this finer grained control? Say that our … [READ THE FULL ARTICLE]
Hello everyone! A few months have passed since I posted Simple Platformer Using Cocos2d and Box2d with Collision Detection. I have received many positive feedbacks and interest on the tutorial. I am glad that it has been helpful for so many in the community! Also, I would like to share the good news that the … [READ THE FULL ARTICLE]
I received a few requests for a simple Mario-like platformer tutorial. So I am keeping my promise. The sample is far from a full fledged Mario clone, but I hope it it can at least start you off in the right direction. This tutorial builds upon concepts covered in “Beginning Box2d Physics Engine” and “Side … [READ THE FULL ARTICLE]
I could not find a simple tutorial that demonstrated a Box2D side scroller with the camera fixed on the player. Meaning, it would give the appearance of the background scrolling while the player remains stationary in one spot on the screen. So for this article, I am going go through a simple tutorial to do … [READ THE FULL ARTICLE]
