I know how to use onItemUse method on a mod item. But how to add such thing to a vanilla item? I've heard about something like PlayerInteractEvent, but I don't really know know how to use it.

Alright. I found own what to do my own. My RightClickEventHandler.java:

package ...

import ...

@Mod.EventBusSubscriber(bus = Mod.EventBusSubscriber.Bus.MOD)
public class RightClickCropStickHandler {

    @SubscribeEvent
    public void handleCropRightClick(PlayerInteractEvent event) {
        Mod.LOGGER.warn("PlayerInteractEvent triggered!");
        ...
    }
}

But there's one little problem. The event is actually never called (PlayerInteractEvent triggered! never appears in the console).

This is not the correct bus for this event.

Yeah, right. I think this is actually a pretty common mistake..
Here is something that works:

package ...

import ...

@Mod.EventBusSubscriber
public class CropRightClickHandler {

    @SubscribeEvent(priority = EventPriority.NORMAL, receiveCanceled = true)
    public static void handleCropRightClick(final PlayerInteractEvent.RightClickBlock event) {
      ...
    }
}

Two new things. The method handleCropRightClick is now static and the event was changed from PlayerInteractEvent to PlayerInteractEvent.RightClickBlock not to get triggered unnecessarily.
