使用 cocos 2d js 和 Chipmunk 创建动态主体

Question

我对 cocos 2d 和花栗鼠还很陌生。到目前为止，我已经设法创建了一个静态对象并向其添加了碰撞处理程序。但我想创造一个动态。

this.space = space;
this.sprite = new cc.PhysicsSprite("#rock.png");
var body = new cp.StaticBody();
body.setPos(pos);
this.sprite.setBody(body);

this.shape = new cp.BoxShape(body,
    this.sprite.getContentSize().width,
    this.sprite.getContentSize().height);
this.shape.setCollisionType(SpriteTag.rock);

this.space.addStaticShape(this.shape);
spriteSheet.addChild(this.sprite);

但我想创建一个类似的动态物体，例如通过以下方式移动：

cp.v(310, 0), cp.v(0, 0)

我知道这是非常基本的，但如果有人能帮助我，我将不胜感激。此外，如果您在 JS 中有 cocos 2d 和花栗鼠的良好文档。分享它。谢谢

给你：

//Add the Chipmunk Physics space
var space = new cp.Space();
space.gravity = cp.v(0, -10);

//Optionally add the debug layer that shows the shapes in the space moving:
/*var debugNode = new cc.PhysicsDebugNode(space);
debugNode.visible = true;
this.addChild(debugNode);*/

//add a floor:
var floor = new cp.SegmentShape(this.space.staticBody, cp.v(-1000, 10), cp.v(1000, 0), 10);
//floor.setElasticity(1);
//floor.setFriction(0);
space.addStaticShape(floor);

//add a square to bounce
//the Sprite
var mySprite = cc.PhysicsSprite.create("res/something.png");
gameLayer.addChild(mySprite);

//the Body
var size = mySprite.getContentSize();
var innertialMomentum = 1; //Use Infinity if you want to avoid the body from rotating
var myBody = new cp.Body(innertialMomentum , cp.momentForBox(innertialMomentum , size.width, size.height));
mySprite.setBody(myBody);
space.addBody(myBody);
//myBody.p = cc.p(xxx, yyy); //To alter the position of the sprite you have to manipulate the body directly, otherwise it won't have the desired effect. You can also access it by mySprite.body

//the Shape
var myShape = new cp.BoxShape(myBody, size.width, size.height);
//myShape.setElasticity(1);
//myShape.setFriction(0);
space.addShape(myShape);

//Apply your desired impulse
//mySprite.body.applyImpulse(cp.v(ix,iy), cp.v(rx,ry)); // Where the first vector is for the impulse strength and direction and the second is for the offset between the center of the object and where you want the impulse to be applied.
