Some problems with the item commands.
I am not sure if I have used these types of commands correctly.

multi-click: Execute command when clicked in inventory.
left-click: Execute command when clicked in inventory.
right-click: Execute command when clicked in inventory.

multi-click-air: Never executed
right-click-air: Never executed
left-click-air: Never executed

inventory: No problems.

Also, I have some suggestion.
I am using the menu plugin "BossShopPro" which has some great command types.
You can refer to it~ The command type of inventory will be more abundant!

• inventory-left
• inventory-right
• inventory-middle (Mouse wheel)
• inventory-shift-left
• inventory-shift-right
• inventory-shift-middle (BossShop does not have this feature, but maybe you can try it?)

In addition, is it possible to add the "Middle-Click" when players use the mouse wheel.
And it may be clearer to distinguish the Click action from the Inventory action?

Once the following information is provided I will reply to you as quick as possible!

1. ItemJoin version: v5.0.6 (release)
2. Paper version: Paper version git-Paper-245 (MC: 1.15.2) (Implementing API version 1.15.2-R0.1-SNAPSHOT) (latest)
3. Test server and default config.yml.

Thanks~ : )

Hey, sorry for hijacking your post but I keep getting really confused each time I revisit this issue. I have simply copied your request to your original feature request post #236 manually editing myself it adding it.

If you have any corrections to make please do so in that post. As well as since I referenced the post it will now forever be linked to this issue as well for future reference.

I will be closing this issue as it will now be completed in #236.

By the way, the download link "Download Now" on Spigot has expired.
I downloaded the plugin file from the download History page.

Hmmm weird, the download link seems to be working for me. What region are you in? I would like to test it with my VPN.

As for the ItemCommands issue, I will be testing this soon. I am currently working on a M.A.S.S.I.V.E commit to the snapshot branch and it pretty much completely rewrites a lot of the pre-exiting methods so I am going to complete it first before I look into further bugs as they might be resolved in this commit. It makes it easier for me to compare v5.0.6 to this future commit.

I am in Taiwan in Asia, if other people can use it, it would not be a big problem~

These issues are not very urgent. Just look at it when you have time.
I wish you a smooth work and a good day!

Okay so, the ItemCommands execution you showed above is operating as intended. The "AIR" commands should never be executed in the inventory as those are specific to interaction.

The commands-type options were implemented for simplicity as most people's use-cases were either one or the other, or both. Usually, they were never unique if that makes any sense.

I like your suggestions so what I think I am going to do is remove commands-type entirely, changing only the inventory part of things adding the suggested inventory actions and I think I am going to rename the existing inventory action to inventory-all to simulate both left, right, and middle click.

-- Also the download link seems to work when using a VPN to connect to Taiwan. Though, I think I may stop redirecting to the bukkit site and set the download link to direct download from curse forge so that way it isn't a redirect, of a redirect if that makes any sense haha.

I am going to bump this up to a feature request so I don't get too confused, as I am going to finish up the rest of the bug reports I have to complete before I start implementing new features for the v5.0.7 release. I have completed the massive rewrite I was talking about so the integration server will be having a lot of dev builds committed.
