I used to know how to do this but I forgot and I can't find anything in the reference or forum about it.

When you right click an object, normally a menu pops up that you can expand and it shows all the verbs you can use on that object. But I have a certain object where I want it to NOT be right clickable. AKA: The menu doesn't pop up. How do I do that? Thanks.
This is different than mouse_opacity because I do not want to disable left clicking the object.

The reason is I don't want players to be able to right click screen objects in client.screen.
You'd either have to set all of the verbs belonging to the object's 'popup_menu' setting to 0 (if the verb has an appropriate 'set src' setting), or make all of the verbs hidden.

The only other way is disabling the menus outright per-client, which isn't what you want.
I requested the ability to disable right-click menus per object like... 7 years ago.

Might be a good feature request for 512.

As a quick workaround, you can empty the screen objects' verb list in New().
