getClickedBlock is null in PlayerInteractEvent

For my plugin, I'm detecting when a player clicks on a sign (either left/right click). Most of this time, this works. I use event.getClickedBlock(), which returns the block the clicked - as expected.

However, in certain circumstances, this doesn't actually work. the clicked block will be null, despite me obviously clicking it.

It only happens when I'm holding a placeable item, and obstructing it from being place. Any other case (actually placing the block, and holding no item) works fine.

Is there something I'm missing?

 

You should be doing null checks on getClickedBlock() - it will return null when you are left or right clicking on air.

 

I know that's the case, I've already adapted to it.
The problem is that I'm obviously clicking the sign, but it believes I'm clicking air. It'll confuse some people when they go to click the sign with item in hand, only to find out it didn't work for them in some situations

 

display chat message that explain situation on fail, this will help users.

 

I can't do that, either. The nature of PlayerInteractEvent means that *any* time the player right-clicked air intentionally, it would tell them they didn't click a sign. Not an option either.

Make sure the action is Action.RIGHT/LEFT_CLICK_BLOCK instead of air
