Wearing Armor on Spawn

I have been messing around I made this to get items on spawn

Code:

public void onPlayerSpawn(PlayerRespawnEvent evt){
Player player = evt.getPlayer();
ItemStack give = new ItemStack(Material.DIAMOND_HELMET, 1);
  ItemStack give1 = new ItemStack(Material.DIAMOND_CHESTPLATE, 1);
  ItemStack give2 = new ItemStack(Material.DIAMOND_LEGGINGS, 1);
  ItemStack give3 = new ItemStack(Material.DIAMOND_BOOTS, 1);
  ItemStack give4 = new ItemStack(Material.DIAMOND_SWORD, 1);
  PlayerInventory pi = player.getInventory();
  pi.setHelmet(give);
  pi.setChestplate(give1);
  pi.setLeggings(give2);
  pi.setBoots(give3);
  pi.setItemInHand(give4);
} 

And I am having the problem of when I spawn I get no items on my body I need some help

 

pi.update();

 

try using player.updateInvetory(), there seems to be some glitches with player inventories.

 

this should work:
pi.setChestplate(new ItemStack(give1)

and so on

 

Sorry I haven't got around to trying any of these methods I will as soo. As I get home and give you all feedback
Thanks

 

Above those type player.getChestplate();
And so on so forth.
