Can you query the mouse class in XNA?
In XNA you can use the Mouse class to query user input. The easiest way of doing it is to check the mouse state for each frame and react accordingly.
How do you pick 3D objects in XNA?
In a 2D game knowing what’s the mouse is over – in most cases – is simple, just check if the mouse is inside a rectangle or a circle for example, in a 3D world it’s a little trickier!. In a previous post I visualized how picking 3D objects works in XNA. (no need to check the old post, every thing you want is here…)
Which is the opposite of picking in XNA?
When picking we want to do the opposite : transform from screen coordinates (mouse position on the screen) to world coordinates, This operation is called Unprojection. XNA struct Viewport provides methods for both projecting & unprojecting points, for now we want the unprojection method which is:
What are the events for mouse clicking in XNA?
So you would still use the snippets from above, but instead of directly including the code for the action you would fire events: MouseIn, MouseOver, MouseOut. ButtonPush, ButtonPressed, ButtonRelease, etc.
How to check for one click in XNA?
To check for a single click you would have to store the mouse state of the last frame and compare what has changed: You could make it even more advanced and work with events. So you would still use the snippets from above, but instead of directly including the code for the action you would fire events: MouseIn, MouseOver, MouseOut.
Change a texture when the mouse is inside a certain area: Do something while the left mouse button is clicked: Remember though that you will always have information of the current frame. So while something cool may happen during the time the button is clicked, it will stop as soon as released.
What kind of input capabilities does XNA have?
XNA input capabilities were at once powerful, straightforward and a bit lacking. If you come from another game engine or library you may be shocked to discovered there is no event driven interface out of the box for example.
How does MonoGame work with keyboard and mouse?
When the user clicks right, the application exits. The logic works almost identically to handling Keyboard input. Each frame you check the MouseState by calling Mouse.GetState (). This MouseState struct contains the current mouse X and Y as well as the status of the left, right and middle mouse buttons and the scroll wheel position.
What kind of input does MonoGame XNA have?
XNA/MonoGame also have support for mobile specific input such as motion and touch screens, we will cover theses topics in a later topic. There is an HD video of this chapter available here. XNA input capabilities were at once powerful, straightforward and a bit lacking.
