UI Buttons Stop Working After I Load Another Scene And Then Come Back.

Question

Hi,

so i have a game over scene and i have 2 buttons (which i created using the new UI menu, i did't create them using script), a restart button and an end game button.

When i create the buttons and i add the OnClick function they work fine, but if i load a different scene and then come back to the game over scene they stop working, they don't even change colors when i hover over them or i press them.

I might know what is wrong. add at Start() { Time.timeScale = 1; }

your game might have been paused to zero, and I don't know why Unity keeps the timescales... sometimes...

I had to do this, but also the event system game object was not in a persistent game object in the hiearchy, so it didn't have DontDestroyOnLoad. I just made it part of another GameObject that had DontDestoryOnLoad AND followed Ironcross's advice for "Force $$anonymous$$odule Active" and all was well again. :)

Tried all of these and didn't fix it. Finally found my problem:

I'm using the standard 1st person controller asset, and it locks the cursor. Need to unlock the cursor when going back to the main menu.

In the past I have had: 1. UI textbox/image is on top of button so it isn't clickable 2. DontDestroyOnLoad doing wonky things 3. Accidentally deleting the "Event System" GameObject in your scene (maybe mispelled it) that handles things like buttons being clicked.

Cheers

I haven't used that standard asset in awhile, but here is a quick answer I found Googling it. I think you can find the the cursor lock state in the Standard Asset script and just change its true/false value. https://answers.unity.com/questions/1179026/standard-assets-first-person-controller-hiding-cur.html

I'm making FPS and when I go back to the title screen the button didn't respond. As you commented, it was because the cursor on the FPS Controller was locked.

It was good to be fixed. Thank you!!!
