在Box2D中绘制自定义多边形
|
我正在制作Flash游戏，尝试在Box2D中绘制多边形时遇到了一个非常奇怪的问题。
这是我使用的代码：
var fixtureDefs:Array = new Array();
...
var fDef:b2FixtureDef = new b2FixtureDef();
fDef.density = 0;
fDef.shape = new b2PolygonShape();
b2PolygonShape(fDef.shape).SetAsArray(vertexArray);
fixtureDefs.push(fDef);
//This gets repeated several times, so that at the end you get a body consisting of several convex shapes.
...
var bD:b2BodyDef = new b2BodyDef();
bD.type = b2Body.b2_staticBody;
bD.position.Set(300/Constants.RATIO,200/Constants.RATIO);
var body:b2Body = Constants.world.CreateBody(bD);
...
for each(var fD:b2FixtureDef in fixtureDefs) {
body.CreateFixture(fD);
}

private var body:b2Body; private var bodyDef:b2BodyDef = new b2BodyDef(); private var bodyPoly:b2PolygonShape = new b2PolygonShape(); private var bodyFix:b2FixtureDef = new b2FixtureDef(); private var vertexArray:Array = new Array(); public function Example() { //Setting up Vertices in an Array var ver1:b2Vec2 = new b2Vec2( -1, -1); var ver2:b2Vec2 = new b2Vec2( 1, -1); var ver3:b2Vec2 = new b2Vec2( 1, 1); var ver4:b2Vec2 = new b2Vec2( -1, 1); //Push in order vertexArray.push(ver1, ver2, ver3, ver4); bodyDef.type = b2Body.b2_dynamicBody; //b2Vec2 Array then Vertex Count bodyPoly.SetAsArray(vertexArray, vertexArray.length); bodyFix.shape = bodyPoly; bodyFix.density = 0.5; bodyFix.friction = 0.5; bodyFix.restitution = 0.5; bodyDef.position.Set(0, 0); body = m_world.CreateBody(bodyDef); body.CreateFixture(bodyFix); }从左到右放置我不太善于解释事物，但我希望能有所帮助！ -零痴浪墨
