我剛剛接受處理，在玩丹尼爾Shiffman Box2D庫時出現錯誤。我正在嘗試使用我在主程序中定義的矢量創建鍊形狀。由於我需要創建多個曲面，因此我爲對象創建了Vec2 [x] [y] x併爲Vec2點創建了y鏈以創建鏈，但我一直使用「類型不匹配」main.Surface「與」不匹配「 「processing.core.PSurface」Box2d處理
這裏是我的全部代碼：
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，那我得到的問題是線6和169之間的問題是，當我嘗試發送到表面構造（這是應該接收VEC 2 [] r）的基礎[I]從無效設置（）{}
我真的很感激任何幫助！錯誤我相信，來自構造函數類創建一個新的表面和我嘗試推到構造函數的類的表面類型。這是在大學的作業，我有點反對時鐘，所以任何幫助將是非常有用的！
非常感謝！
你有沒有得到這個整理出來？ –
