I deleted all saves
and this is how it starts
Will not help since the resolution and quality data is comming from wherever Unity saves that data and not from where plyGame saves it. Also, deleting save data via the Unity editor will nto help for a final built game since the editor and final builds save their data in different locations (different registry keys).
If I click the “apply” button, it reverts
The Apply button is using the plyBlox “Apply Resolution” which had nothing to do with the script you used. It expect you to have made plyBlox calls to update the “selected” resolution as shown in my settings screen video. So, since you did not make those call it will change to whatever last thing it knows about. Yes, you need to remove “apply resolution” since the sript seems to apply it on the spot when you choose a new resolution.
do you know if your drop down script could be causing this
No. that script (attached in this thread) does not mess around with the quality settings. Test the build on a different computer and you will probably see it start up with the defaults you set in Unity.
One thing to keep in mind is that plyGame will override whatever you select in that first dialogue if there is currently saved settings. plyGame does save what you select so that it force restore to those settings when the game starts. That is one reason to not have that dialogue (except for while you are testing stuff). So ye, testing on your current device will not really help since there is data saved related to this.
One thing you can try is to make it look like a different game. This way you start with no saves. Go to
Edit > Project Settings > Player and change the Company and Product names. These are what is used when generating the save keys.
You will find the product name in the registry if you run regedit and search for that name. That is one way of inspecting what values are saved for the game and you could simply delete the registry entry to also get rid of the saved data. Just be sure to be looking at the correct entry since there would be one for the Unity editor version and one for the stand-alone version of the game.
