[1.14] Handling mouse movement in inventory

[DavidM]

I am trying to detect when a player clicks on an ItemStack in his inventory with another ItemStack (held by the mouse).

I recall that all the inventory and GUI interactions are client-side; however, I've seen servers achieve this (clicking on ItemStack with ItemStack) with server-side plugin/mod.

How would I approach this?

Clicking is processed in the Container which is client and server. Override slotClick or onSlotClick(its one of those) and perform your action there. Then update the player by calling sendAndDetectChanges.

Oops yeah, at least I got the words right.
