chipmunk flag

represents the conflict between an object and other objects. What needs to be done between the genie and the conflict form is that you may match the conflict form with the sprite shape. Chipmunk BasicsBasic knowledge of chipmunk Initialization Before you do anything else, youMustInitialize chipmunk. Otherwise youWillCrash as soon as the first collision happe

Tracking the ball's movements NoCodeConnect to the chipmunk simulator. Only after the corresponding method is extended can the position of the image be synchronously updated through chipmunk. This process can be implemented in multiple ways, such as storing a set of vertices to be checked. Fortunately, chipmunk has designed a very simple and abstract process fo

Add Chipmunk physics engine in our world of gamesFirst, IntroductionCocos2d JS can give us the power to create an impressive game world. But the lack of a certain reality.While we can do complex calculations to make the game world more realistic, there is another optionIt can alleviate our life. The answer is the physics engine.The physics engine provides gravity, collision detection and physical simulations that can make our game world look more real

Setup Before we start practical application, we need to set up a project so that we can focus on chipmunk. Open xcode, create a new project, and use the 'view-based 'application.ProgramTemplate to create a simple application. After the application is started, a view is displayed. We generally need to import the chipmunk file. This task will be completed in several steps, including creating a static libr

Vect, s,t,d,dist for float Cp. Bool cp.v.eql (v1, v2) – detects the equality of two vectors. When using a C + + program, Chipmunk provides an overloaded operator == . (Be careful when comparing

Recently see some cocos2d-js things, use the chipmunk of some of the things, because the relevant information is not very detailed, so see something useful on the record.1. Chipmunk is a physical engine of the cocos2d that simulates the reality of gravity, collisions, and so on.A chipmunk body represents an object in a virtual space and may contain one or more

, the problem is gradually locked out on stick. Thus again, reasoning involves the possibility of deleting code logic that conflicts with references.Finally infer what happens if the stick is deleted at this time after the pentagram collision stick in the collision callback!? This is certainly not what the physics engine is willing to see: In a collision callback for a physical object, the physical object is deleted! This is obviously counterintuitive, but it can happen in the app.If the stick d

The collision behavior in the Chipmunk engine may be slightly different from the general perception in detail.For example, the collision callback method may be re-entered. Do not know the method (function) to re-enter the concept of children's shoes can be self-gu brother or degree Niang.The first collision method has not yet returned, and the second collision callback is called again. As to whether they are running on the same thread, this does not k

normal size of the stick need to shorten it, the practice is:1. First create a short stick in the original stick position, but set it to be invisible, because there is also a shorter animation effect;2. Create a stick node without a physical object and perform a shorter animation;3. Delete itself at the end of the animation and make the short stick visible. Note that animation time needs to be moderate, neither too long nor too short. This will be detailed in the iOS Game Development Series blo

There is an array, the length of N, which is only 0, 1, 2 (respectively for red, white, blue), now requires the way through 22 exchanges, so that 0 in the front, 1 in the middle, 2 in the last.
