java - 如何为迷宫/迷宫/地牢 build 墙壁？

Question

我使用的代码只是取自一个示例，它确实为我的场景建了一堵墙:

  /** This loop builds a wall out of individual bricks. */
  public void initWall() {
    float startpt = brickLength / 4;
    float height = 0;
    for (int j = 0; j < 15; j++) {
      for (int i = 0; i < 6; i++) {
        Vector3f vt =
         new Vector3f(i * brickLength * 2 + startpt, brickHeight + height, 10);
        makeBrick(vt);
      }
      startpt = -startpt;
      height += 2 * brickHeight;
    }
  }

  /** This method creates one individual physical brick. */
  public void makeBrick(Vector3f loc) {
    /** Create a brick geometry and attach to scene graph. */
    Geometry brick_geo = new Geometry("brick", box);
    brick_geo.setMaterial(wall_mat);
    rootNode.attachChild(brick_geo);
    /** Position the brick geometry  */
    brick_geo.setLocalTranslation(loc);
    /** Make brick physical with a mass > 0.0f. */
    brick_phy = new RigidBodyControl(2f);
    /** Add physical brick to physics space. */
    brick_geo.addControl(brick_phy);
    bulletAppState.getPhysicsSpace().add(brick_phy);
  }

现在我想知道我是否应该使用这段代码来构建整个迷宫/地牢，或者这是否最好在程序之外建模，例如。在 blender 中而不是像 .scene 然后读入程序？整个程序是

在您的示例中，您有大约 100 多 block 积木 - 想象一下完整地牢需要多少积木，以及它会如何破坏您的物理性能 :)。用这种方法创建可玩游戏几乎是不可能的。

您应该创建一些静态网格并将其划分为走廊、房间等，这样您就可以只绘制关卡的可见部分。如果您真的想创建可破坏的环境，您仍然应该使用静态网格物体，并在墙壁应该被破坏时动态地用砖 block 替换它的一部分。
