我的应用程序有一个自定义面板,用于在WinForm中显示XNA屏幕。目前我已经展示了一个没有问题的测试模型,现在正在处理相机移动。我的相机是一个免费的相机(不一定要看任何特定的目标),但我一直无法让鼠标更新相机在其轴上的偏航和俯仰。我认为我的更新方法可能有问题,但情况并非如此,因为相机使用KeyboardState
更新前后移动。但我不知道为什么MouseState
不起作用。鼠标事件不会更新winforms中的相机旋转
FreeCamera.cs
using XNAButtonState = Microsoft.Xna.Framework.Input.ButtonState;
....
MouseState pastMouseState;
private float rotationSpeed_ = 1f/60f;
private float yaw_, pitch_;
...
private void updateMatrix()
{
Matrix rotationMatrix = Matrix.CreateRotationX(pitch_) *
Matrix.CreateRotationY(yaw_);
Vector3 forward = new Vector3(0, 0, 1);
forward = Vector3.Transform(forward, rotationMatrix);
viewMatrix_ = Matrix.CreateLookAt(Position, Position + forward, Up);
projectionMatrix_ = Matrix.CreatePerspectiveFieldOfView(
MathHelper.PiOver4, 16.0f/9.0f, 0.1f, 100000.0f);
}
private void cameraInput()
{
KeyboardState keyboardState = Keyboard.GetState(); <-- updates
currentMouseState = Mouse.GetState(); <-- not updating
if (currentMouse.LeftButton == XNAButtonState.Pressed)
pitch_ -= rotationSpeed_;
if (keyboardState.IsKeyDown(Keys.W))
move(1);
if (keyboardState.IsKeyDown(Keys.S))
move(-1);
pastMouseState = currentMouseState;
}
public void update()
{
cameraInput();
updateMatrix();
