Basic question on Stopping Block Placement

The most basic question how do u stop block placement? Im not having a good programming day.

I want to stop players from being able to placeblocks but they are allowed to use redstone.

 

Code:

@EventHandler
public void onPlace(BlockPlaceEvent event) {
        event.setCancelled(true);
}

Seems to work just fine for me

EDIT: Oh but you want them to be able to use redstone? Sorry haha thought you tried something but it still let them place redstone. Hold on.. Okay, try something like this:

Code:

@EventHandler
    public void onPlace(BlockPlaceEvent event) {
        if (isRedstone(event.getBlock())){
            event.setCancelled(false);
        }else {
            event.setCancelled(true);
        }
    }
 
    private boolean isRedstone(Block block) {
        if(block.getType() == Material.REDSTONE_WIRE ||
            block.getType() == Material.REDSTONE_TORCH_ON ||
            block.getType() == Material.DIODE_BLOCK_OFF){
            return true;
        }else {
            return false;
        }
    }

 

Are you trying to stop lever interaction and stuff (buttons levers and stuff like that) if thats what you want to block you have to use leverInteractEvent and buttonInteractEvent. Cancell those

@EventHandler
public void onPlayerBlockPlace (BlockPlace event) {
Player p = event.getplayer();
Block block = event.getPlacedBlock();
if(((Object) block).getTypeId()==55){
event.getPlayer().sendMessage("You are not allowed to place this!");
event.setCancelled(true);
