Here is what’s in my HandleKeyboard() method that is called from the Game1 Update method.
MouseState mState = Mouse.GetState();
// the Vector2 that will hold the angle from the player to the mouse pointer.
Vector2 mDirection = new Vector2(0, 0);
// Get the current mouse position from the state update in the beginning of this method.
Vector2 mPosition = new Vector2(mState.X, mState.Y);
// Subtract the potsition of the player fromthe mouse pointer to get the exact angle in a vector2
mDirection = mPosition - arrow.Position;
// Control Rotation
arrow.FixedRotation = true;
// display the arrow in the rotation gathered above.
arrow.Rotation = (float)Math.Atan2(mDirection.Y, mDirection.X);
From what I have read, this seems like the exact right thing to have the arrow look at my pointer. However when I rotate the mouse around the pointer it really doesn’t work properly.
It's hard to explain so here is a
displaying what’s happening
EDIT: have also added in a few lines to normalize the mDirection. but it still doesn't affect the behaviour unfortunately.
I really hope you can tell me what’s going wrong.
