Right-click?

Hello i want to do an action when you do a simple right click. but not to block or entity, with item, and in bukkit, but i know how can get an right-click on block or entity, and i kow the event to do a click on “air”
InteractEvent (if i have false and if there is an another event, can you say it plz?)

but i don’t know how can i get if it’s a rightclick or a leftclick…
how can i do it?

I know that there are some limitations on detecting air-clicks because the client does not send a packet in some circumstances or something?

This question is already asked here:

oki, it’s sad…
but i think i know how can i do it :wink:
