我刚刚接受处理，在玩丹尼尔Shiffman Box2D库时出现错误。我正在尝试使用我在主程序中定义的矢量创建链形状。由于我需要创建多个曲面，因此我为对象创建了Vec2 [x] [y] x并为Vec2点创建了y链以创建链，但我一直使用“类型不匹配”main.Surface“与”不匹配“ “processing.core.PSurface”Box2d处理
这里是我的全部代码：
class Surface {
ArrayList<Vec2> surface;
int id;
Surface(int id_, int largo, Vec2 [] r) {
id=id_;
surface = new ArrayList<Vec2>(largo);
for(int i = 0 ; i < largo ; i++){
surface.add(new Vec2(r[i]));
}
ChainShape chain = new ChainShape();
Vec2[] vertices = new Vec2[surface.size()];
for (int i = 0; i < vertices.length; i++) {
vertices[i] = box2d.coordPixelsToWorld(surface.get(i));
}
chain.createChain(vertices, vertices.length);
BodyDef bd = new BodyDef();
Body body = box2d.world.createBody(bd);
body.createFixture(chain, 1);
}
}

所以，那我得到的问题是线6和169之间的问题是，当我尝试发送到表面构造（这是应该接收VEC 2 [] r）的基础[I]从无效设置（）{}
我真的很感激任何帮助！错误我相信，来自构造函数类创建一个新的表面和我尝试推到构造函数的类的表面类型。这是在大学的作业，我有点反对时钟，所以任何帮助将是非常有用的！
非常感谢！
你有没有得到这个整理出来？ –
