Solved How do i make a chest do something on open?

Code:java

Chest YourChest = (Chest)event.getInventory().getHolder();

Code:java

try
{
Field inventoryField = YourChest.getClass().getDeclaredField("chest");
inventoryField.setAccessible(true);
TileEntityChest chest = ((TileEntityChest) inventoryField.get(YourChest.getBlock().getState()));
chest.a("Your name");
}
catch (Exception e)
{
e.printStackTrace();
} 

Code:java

if(YourChest.getBlockInventory().getTitle().equalsIgnoreCase("Your name")) {
}

 

Didnt work D:

 

I re-edited my code.

 

G2g cya tomorrow. Thanks everyone for all your help at least we got the code to make the chest do something now

Code:java

 if (event.getClickedBlock() != null) {
if (event.getClickedBlock().getType() == Material.CHEST) {
player.playSound(player.getLocation(), Sound.ORB_PICKUP, 1.0F, 2.0F);
player.addPotionEffect(new PotionEffect(PotionEffectType.INVISIBILITY, 99999, 1));
}
}

Once again thank you
