Open Command Block GUI When Right-Clicking on Entity???

[perigrine3]

I think the title was pretty self-explanatory, but just in case, I'm looking to have the Command Block GUI open when a player right-clicks on an entity. I came up with a way, looking at the Command Block GUI class, but it's returning with an error. Thoughts? 

 

Here's my code: 

public boolean rightClickEntity(EntityPlayer entity, EnumHand hand) {
            super.processInteract(entity, hand);



if (entity instanceof EntityPlayer)
             playerIn.displayGuiCommandBlock((TileEntityCommandBlock)tileentity);
}

 

(P.S.: I am really bad with imports so it could just be that because the auto-import setup isn't working for me because for some reason the Minecraft Forge mdk thing isn't uploading and it's being a pain in the a**, so I've been adding the imports manually.)

You don't show where this tileentity is coming from, but odds are either it doesn't exist (is null) or isn't a tileentity.

Ok thank you. are there any alternate ways to go about doing what I'm trying to do?

I'd suggest you take a look at EntityMinecartCommandBlock, as it seems extremely similar to what you want.
