[SOLVED][1.19.4] Replace a block before is actually placed into the world

[JimiIT92]

In my mod I'm making so that if the player tries to place some glass panes while sneaking it will be placed another block (a horizontal glass pane). To do so I'm listening to the block place game event and so far everything works. However for a split fraction you can see the vanilla glass pane before it gets replaced by the mod block. Is there any way to prevent this and instead just straight forward place the mod block without placing the vanilla block and then the modded one?

You can see how I replace the block here:

By the way I've also tried listening to the BlockEvent.EntityPlaceEvent, cancelling and then set my own block, but that didn't worked at all (and not cancelling the event would produce the same result where you can see the placed block before is replaced)

It's not possible unless it is your block so can you override the logic in BlockItem.place()

This is because the vanilla client is simulating what it thinks should happen to give more immediate feedback to the player.

 

The vanilla BlockItem already places the block on the client side before calling the server where the event can decide a different block should be placed.

A similar thing happens when you cancel the block break event. The client momentarily displays the block as gone.

Understood, so I guess it's fine till it works. 😅
Of course if it was a custom block in the first place there wasn't even the need for the event
