Hey this might be a bug I don't know.

I have drawn my own mouse cursor in the game and have set the coordinates to equal the position of the mouse upon each update loop.


I then draw it at the end of the draw loop.


The problem is when I played the game in windowed mode the cursor doesn't match exactly to the current position of my mouse. This has led to being able to click on items outside of the game even though the cursor suggests it's still in the game.
When I play the game in full screen mode sometimes I can't pull the mouse cursor to the bottom of the screen, there seems to be a border which stops me.
Is this a resolution issue? Or have I done the mouse code wrong?

It's not a bug in XNA but something is wrong in your code.

Why don't you turn on the windows cursor, to compare against.

this

 

.IsMouseVisible = true;

I miswrote that a bit, I didn't mean to suggest theres a bug in XNA.
I've made the mouseVisible but when the game starts the cursor never seems to map exactly to the mouse pointer, it always seems to be at a distance.

Could it be issues related to the window border at the top?

How far off is it?

Is it consistantly the same distance off?

It's about the same distance everytime. Also depends on where the mouse is when the program starts, sometimes the displacement is down right or sometimes its top right.

I probably won't be able to answer again for awhile, (going back to work)

but how far off is it on startup.  Before moving the mouse?

Does the distance grow while the mouse moves?

If you move the mouse outside your game during play, then do something with another application and move the mouse around, then go back to your game.  What are the results?  Same offset, or did the offset change.

The distance doesn't grow as you move the mouse around, it remains constant. The offset is different depending on where the mouse cursor is on start up, if you go do something in another application though the offset remains the same, so it must be something when the game starts up.

If I were you, I would make sure to set the mouse at the screens center at application startup.

 

Mouse.SetPosition(centerx, centery);

NinZip,

You might want to post a bit more code as I don't think anyone is going to be able to help you as it stands. I've written a game that runs completely in Windowed mode and draws the mouse cursor on screen so it is possible.

Hey,
Sorry this is so late, been busy for the past week.

I tried centring the mouse at the start however there still seems to be a displacement. I added some break points and at the initialisation stage mouseX = 400 and mouseY = 300

Upon the first update without any movement MouseX = 527 and MouseY = 239

 Here is all the mouse code I have in terms of movement.

Initialising the variables.

 
Initialise()
 

Then here is the code at the update stage:

And at the drawing stage:
