Description
Problem occurs when I try to use custom SkullMeta
public static void setupHologram(Location location, String name, Material material, Player player){
ItemStack itemStack = new ItemStack(material);
if (material.equals(Material.PLAYER_HEAD)){
SkullMeta skullMeta = (SkullMeta) itemStack.getItemMeta();
itemStack.setItemMeta(getCustomTextureHead(skullMeta, "eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvMmRmODYxZDViOTI1NTQxMTQwN2ZjOTJjZGM1NzdhNDc3MzU4NzM4NjY0M2Y1NTE4ODM0NDgyM2MwM2IxNzlkIn19fQ=="));
}
Hologram hologram = HologramsAPI.createHologram(plugin, location.add(0.0, 3.2, 0.0));
hologram.appendTextLine(name);
hologram.appendItemLine(itemStack);
BetterDecoratePlugin.holograms.put(player.getUniqueId(), hologram);
}
private static SkullMeta getCustomTextureHead(SkullMeta skullMeta, String base64){
GameProfile profile = new GameProfile(UUID.randomUUID(), "");
profile.getProperties().put("textures", new Property(("textures"), base64));
Field profileField = null;
try {
profileField = skullMeta.getClass().getDeclaredField("profile");
profileField.setAccessible(true);
profileField.set(skullMeta, profile);
return skullMeta;
}
catch (IllegalArgumentException | IllegalAccessException | NoSuchFieldException | SecurityException exception){
exception.printStackTrace();
return null;
}
}How to reproduce
- Trying to create a custom hologram using the API
- Try using the API to teleport the hologram you just created
- The following error occurs
[15:15:03 ERROR]: [HolographicDisplays] Error while ticking holograms
java.lang.NullPointerException: Cannot invoke "net.minecraft.nbt.NBTTagCompound.equals(Object)" because "this.serializedProfile" is null
