Hello,
The issue where, when playing in a resolution that was less than the native resolution for the monitor, the ball and menus did not register direct clicks has been resolved. No further work-arounds should be required, it should now work normally regardless of resolution selected.
** previous notes **
I am aware that on some configurations the mouse clicks do not appear to register. This appears to affect all menus and the ability to click-drag on the ball. This issue occurs when you tell the initial screen to play at a full-screen resolution that does not match your system's current resolution... playing at 1024x768 when your resolution is 1920x1080, for example.
** Work Around **
For the time being, the following solutions will work in every environment that I've tested.
1) Play the game in windowed mode. This will work in any resolution and while it breaks immersion, if you really want to play in 1024x768 resolution when your machine is set to 1920x1080 you can do so.
2) Play the game in whatever resolution is native for you. If your screen's resolution is 1024x768, play in that resolution. If it is 1920x1080, play in that resolution.
** Investigation log **
Initial investigation shows the mouse click/drags work if you play on a resolution of 1920x1080. The 'quality' does not appear to play a role. Playing at a resolution less than 1920x1080 will not detect the mouse cursor location with regards to menus or the ball. This can be tested in the initial menu, attempts to hover over mouse buttons do not result in them highlighting.
** follow up **
The issue occurs when playing in a resolution that is not the default resolution for the display. If the default resolution is adjusted to match game resolution, the issue does not occur.
When the resolutions are mismatched, the mouse does actually highlight menus and click 'on' the ball, but does so a small distance to the left of whatever the object it's clicking on is. This offset error appears to be a bug within the Unity software itself for the version that I used to compile Autumn Park Mini Golf. The official recommendation is to upgrade Unity to version such and such, but that version does not support the menu system I use nor will the environment look correct due to versioning of various shaders.
So it's a bit of a pickle. I'm now working with previous versions of Unity to see if an earlier incarnation will do the trick. It should work eventually, because I didn't have this problem when I first started working on this project 2+ years ago. It's time consuming to install older version after older version to find the right one, but I will continue to work until these menus-clicks work correctly. For now, I ask players to use one of the two work arounds I post above.
*** Additional Follow Up ***
I've determined which version of Unity to run off of to ensure that the menu systems will work correctly. I'm now testing the game itself to ensure that by downgrading the compiler, I'm not breaking any existing features.
