Last night I was setting a examine interaction to a item, then somehow all the item in the inventory bar cannot response to left clicking or right clicking.
I choose 'content sensitive', and all the time just left click an item, it can be selected and along with the mouse cursor.
Now, when my mouse hove over the item, the 'use' and 'examine' cursor still can appear, but after clicking, nothing happen.
Did i set something wrong?
I have been searching answer for almost two days, so stressful and worrying.
Hopefully someone had fixed this kind of issue before.
It looks like you're new here. If you want to get involved, click one of these buttons!

The menu is showing normally. Just the item in the inventory bar only show their "use" cursor, but I cant use left clicking to select them.
Is it possible to reset something...
I've checked my settings. It seems ok. I really couldnt find out what's wrong.

Welcome to the community @Hululu.
Apologies for the stress. Don't worry though - I'm sure we can get to the bottom of this. I'll need to know a few more details, however.
What are your AC and Unity versions, and can you share screenshots of both your Inventory menu's properties, and those of the Items/InventoryBox element within it (the element that displays the items)"?
We can check if this issue is caused by your Menu by temporarily switching back to AC's default interface. To do this, go to the top of your Menu Manager, and set the Asset file field to Default_MenuManager. If you then run your game, do items become selectable once again?
If not, share a screenshot of a typical item's properties, as well as any ActionLists you have assigned in its Interaction fields.
Thank you for helping, Chris.
I set the Asset file field to Default_MenuManager, and suddenly the items in default inventory menu are all clickable.... so the issue may stays in my own menumanager. I will post screenshots of it later..
My AC version is V.177.2, Unity 2020.3.48f1c1
I dont know what happen to my menu. It was working smoothly well until yesterday. Where should I check? Or maybe remake/copy the default menu... i dont know
Thanks for the details.
v1.77.2 is a very old version - are you not able to update?
I'm not seeing any obvious issue from the screenshots - the Menu accepts input, and the InventoryBox accepts item selection.
We can see if it's an issue with your specific Inventory menu by copying it into the Default_MenuManager asset (and checking Start game locked off? in the original one, so that it doesn't show as well). Does your Inventory menu, present within the Default_MenuManager asset, work as intended?
If so, are there any other Menus you've created that may be interfering? Perhaps another Menu, invisible, is overlaid above it at the time, preventing clicks.
Thank you Chris. I did copy the Inventory menu into the Default_MenuManager asset, and it worked. So it must be something wrong with my present MenuManger. I created a menu the day before yesterday, in order to present a pop up picture, after player click on the item inside inventory bar. Later I gave up this idea, so I deleted this menu. Since then, my inventory hasn't function normally. Wondering perhaps because of that?
I tried to check 'Start game locked off' in all menu except Inventory to see whether it can work, but it still cannot be 'pick up' by left click. So strange
I copied the default Inventory menu to my current MenuManager asset, and it works normally. Same, I copied my customized Inventory menu(the unclickable one), it also can works.
IDK why haha... maybe I should just delete the old one and use the copied one? Maybe some scripting in my MenuManage is aiming to the old one as the Object (preventing it from interaction), so I just turn to use another copy of it, is that okay?
If the default Inventory menu works in your own asset, then yes - probably best to delete the old and re-style this copy.
I can't tell from the screenshots why this would be - but keep an eye on things and let me know if this occurs again.
Sure
Thank you so much, Chris.
