Send Block Change Effect doesn't work

[static sparrow]

this might actually just be because when you right click a client block it goes back to being what the server thinks it is. Try doing block above target block

no, you'd have to wait a tick

yeah that should make it work without waiting but if you want the actual block the player clicked to change you'd probably have to wait a tick

Well, events actually fire before the thing it's fireing from happens (mostly) so the rightclick event fires before the servers says, alright you rightclicked that block.
