[Solved]How to make a entity spawn on right click, and then make the item disappear?

[ComputerCraft32]

Hello guys! I am currently working on a vehicle. I have an item that spawns the vehicle. When it is right clicked, the entity will spawn. However, the item wont go away! I need the item to disappear after right click, and after the entity is killed the the item will drop. How would I do so? I already tried looking at Item Boat, no luck :(. If I could not do that, then could I make the entity spawn like the iron golem? I went into blockPumpkin and saw some code I maybe be able to use, the hard thing it customizing the shape. Anyways, thanking for reading!
