Question

我想知道是否有一个变量或方法可以用来在我的游戏中旋转相机。我可以沿着xyz轴移动它，但我无法弄清楚如何旋转它！：o

以下是变量：

    Model spaceShip;
    float aspectRatio;
    Vector3 modelPosition = Vector3.Zero;
    float modelRotation = 0f;

    Vector3 cameraPosition = new Vector3(0f, 50f, 5000f);

以下是它的绘制方式（模型（宇宙飞船））：

        Matrix[] transforms = new Matrix[spaceShip.Bones.Count];
        spaceShip.CopyAbsoluteBoneTransformsTo(transforms);

        foreach (ModelMesh mesh in spaceShip.Meshes)
        {
            foreach (BasicEffect effect in mesh.Effects)
            {
                effect.EnableDefaultLighting();
                effect.World = transforms[mesh.ParentBone.Index] * Matrix.CreateRotationY(this.modelRotation) * Matrix.CreateTranslation(this.modelPosition);
                effect.View = Matrix.CreateLookAt(this.cameraPosition, Vector3.Zero, Vector3.Up);
                effect.Projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45f), aspectRatio, 1f,200000f);
            }
            mesh.Draw();
        }

并加载此宽高比：

aspectRatio = graphics.GraphicsDevice.Viewport.AspectRatio;

你可以尝试旋转场景的根容器（不应该包含摄像头，对于摄像头，你应该在根目录外面有另一个容器）围绕摄像头看方向矢量
