I have a question about the PlayerInteractEvent, specifically the different behavior on the Client and Server threads when the player is right-clicking on a previously-placed ladder block while holding another ladder. Given the following test code snippet: @SubscribeEvent public void clickOnLadder(PlayerInteractEvent event) { if (event.pos != null) { System.out.println(event.pos.getX() + " " + event.pos.getY() + " " +event.pos.getZ()); System.out.println(event.world.getBlockState(event.pos).getBlock().getLocalizedName()); } } When right-clicking a placed ladder with an empty hand, I get: [22:58:56] [Client thread/INFO] [sTDOUT]: -324 82 412 [22:58:56] [Client thread/INFO] [sTDOUT]: Ladder [22:58:56] [server thread/INFO] [sTDOUT]: -324 82 412 [22:58:56] [server thread/INFO] [sTDOUT]: Ladder When holding a ladder, I get: [22:58:56] [Client thread/INFO] [sTDOUT]: -324 82 412 [22:58:56] [Client thread/INFO] [sTDOUT]: Ladder [22:58:56] [server thread/INFO] [sTDOUT]: 0 0 0 [22:58:56] [server thread/INFO] [sTDOUT]: Stone Is the client-side event somehow suppressing / not sending to the server as a result of holding a ladder? When holding a ladder, on the Server-side, this makes it impossible to get the coordinates of the clicked block. Could someone please explain why this would be? Thanks!
