alright so I'm trying to make an event that basically "if conditions are met spawn sword in hand and if conditions are met for other if statement remove sword" but thing is when i tried the event it seemed to run both if statements at almost the same time making my sword invisible upon spawning it i basically had to throw the sword out of my inventory to see it then i tried checking if the world wasn't remote for it to work but when i do "if(!world.isRemote)" it basically completely stops working. no code is run. 
My event class.

1) You have fields that you can't have (what happens when there's more than 1 player?) You shouldn't need either of these variables anyway. If the sword exists, it must be in the active hand to be removed (if the sword exists at all, and can be removed, then its been spawend). If the player moves the sword to a different slot then itemArea will be wrong.

2) RightClickEmpty already runs when the active hand slot is empty, so why are you checking to see if the active hand slot is empty?

3) And of course, if there's a sword in that slot, the event won't fire because you right clicked while not empty

4) Your code style is awful, please put the two if statements on line 38 on different lines and correctly indent things.

5) Don't check chest.getItem().equals(ModItems.HANZOS_CHESTPLATE) && playerIn.isSneaking() twice. Put those in the outer if statement.

thanks, None of that would really fix my major problem but those are things i should've fixed either way, in the end i figured out the problem and im currently fixing it.
