Solved Spawning Minecart with Custom Item Block

So I have been trying to spawn Minecarts with custom blocks inside of them. I've seen recently that with McEdit, with a Filter that SethBling made. With it I can modify a minecarts metadata and have the minecart have a block in it, instead of TNT or a Chest.

I've been trying to replicate this with Server Code, but I not sure how to continue, or even if its possible

I have this so far. The code is running off of the PlayerInteractEvent

Code:

Entity ee = event.getPlayer().getWorld().spawnEntity(new Location (event.getPlayer().getWorld(), 0,80,0), EntityType.MINECART_TNT);
                        ee.setMetadata(String, MetadataValue);

 

From MylesIsCool

 

Code:

EntityMinecartAbstract ema = (EntityMinecartAbstract) ((CraftEntity)cart).getHandle();
ema.k(Material.GRASS.id());
ema.l(0);

You will need CraftBukkit

Inside the k method, you put in the Material ID
Inside the l method, you put the damage/data value

 

Thanks so much! I had searched for a while.

Have a great day!
