Hello I have multiple calls to SetRawMouseVisible(). I call it at the start of my app setting it to 1 or 0 depending on saved settings. I then have an options menu where you can toggle window/fullscreen window which also toggles SetRawMouseVisible(), and it doesn't work unless I remove the call to SetRawMouseVisible() at the start of my app. Also, calling SetRawMouseVisible(1) twice (right after each other) also breaks SetRawMouseVisible functionality. I am using Windows 7 x64, Intel CPU and Nvidia GFX.

Having quickly checked this...your right and I have get similar results.... and it is a bug.

However, two calls to SetRawMouseVisible(1) can be undone by two calls to SetRawMouseVisible(0)

It returns the function to working again so it would seem like it doesnt break but works in some weird cumulative fashion. Quite odd.
(Windows 10 x64, Intel CPU and Nvidia GFX here too)

Simply storing your own internal variable and then only calling the SetRawMouseVisible() when it has to be changed is a quick workaround.

Yes this is how it works in windows , it has a mouse visible counter per window, so if you call SetRawMouseVisible(0) 3 times you have to call SetRawMouseVisible(1) 3 times to get the mouse visible counter down. This is how windows works and is not a bug in AppGameKit , also it works different in Mac/Linux , and can give different results if you also switch to fullscreen. The only way i found that seams to always work on all platforms is this:


or:


Looks strange but works on all platforms , even if you also change fullscreen in the same sync.

Yes, that is how it works on windows ....but its not how AGK's documentation explains it. The documentation simply gives 1 for show or 0 for hide.

At the least AppGameKit should only make a call the windows ShowCursor() once in either direction to hide or show the cursor and then do nothing on further calls of of the AppGameKit SetRawMouseVisible() function so that the AppGameKit functions will always work.

Either that or the documentation for SetRawMouseVisible() should be updated to reflect that it is simply wrapping a win32 function and explain that a counter is used.

Yes guess Paul could loop it until GetCursorInfo is actually visible or not visible , then there is only the Mac problem , it will not work while the "going from window to fullscreen animation" is playing , so i also had to call it multiply times with the sync to make it work on mac , but perhaps there is also a way on mac to loop it for Paul
