Cancel GUI open

I am trying to prevent players from being able to open command blocks, but I have not had any luck. Can someone provide some code that works to cancel the event.

This is what I tried to cancel the command block from opening:

Code:java

@EventHandler
public void onInteract(PlayerInteractEvent event) {
Player player = event.getPlayer();
 
if (event.getAction() == Action.RIGHT_CLICK_BLOCK) {
Block block = event.getClickedBlock();
if (block.getType() == Material.COMMAND) {
event.setCancelled(true);
player.sendMessage("You can't open command blocks.");
}
}
}

For some reason, the message will display, but it will still open the command block GUI, who knows how to cancel this.

I found that this will work with other things such as brewing stands, but anyone know why I can't get the command block to cancel?

567legodude hm, you may want to use InventoryOpenEvent and check the InventoryType, instead. I think that may work.

EDIT: nevermind, you can't check if the InventoryType is a command block AFAIK

 

drpk There is only Inventory types for Anvil, Beacon, Brewing, Chest, Crafting, Creative, Dispenser, Dropper, Enchanting, Ender_Chest, Furnace, Hopper, Merchant, Player, and Workbench. So there is no way for me to tell if it is a command block. Another thing is that a command block does not trigger the InventoryOpenEvent.

 

try

Code:java

player.closeInventory();

 

Is the point just to prevent players from seeing what command is inside the block? Because they shouldn't be able to edit them anyway, because you need creative and op
