Signs on Minecarts?

ive seen with one of the chest plugins you can place a sign directly on the chest to lock it. my question is how do i do that to minecarts and allow the cart to move?

 

Carts are entities, but signs (and chests) are blocks. This won't be possible.

 

The guy above me is right.
If you attach a sign to a block and when it moves and the sign moves, it'll eat up CPU power and lag the server a lot.

 

Moving one block for a server is like picking its nose. It would just look really bad.

 

Right.

 

Would have been funny though right?

*Minecart zooms past you and a friend*
You: O_O
Your Friend: "Did that say eat my dust twats?"
You: *nods*

 

yes that was the idea. a license plate plugin.....

 

Ah, that wouldn't work because the minecart tracks would be in the way

 

That's actually not what he was stating at all. It simply isn't possible to have the sign attach to a moving entity. It has nothing to do with memory usage...it just isn't possible. Period.

 

@DrBoweNur I think your missing the point. If you attach a sign to a entity, you'll have to update it's position. That can eat up CPU power. I know it's impossible, just don't keep reminding me.

 

What point? My point is that your point is null and void. I'm sure it would eat up power if it were possible, but it isn't. I fail to see how it's worth mentioning what 'might' happen, if you'd never be able to test it in the first place

 

@DrBoweNur That was what I mean. It would eat up power if it was possible.

 

If it were possible and signs were an entity, then all it would be doing is making the sign move, which is already what the minecart is doing. How would that take up power?

 

I think what they are both trying to get at is.

Signs are not useable on moving entities; so it would take a heavy memory usage to actually move them like that; but since they ARE currently only useable on blocks and not entities, it's not possible anyways? Right?

 

No, it's literally not possible to move signs fluidly because they are not entities. It is not possible at all. There is no discussion about how much processing power it would take, because it is not possible. At all. (Unless Notch changes his code, of course.)

 

@cholo71796
Eeeeee'yup.

 

That maaaaay actually change with pistons. I don't know, the bukkit team was saying that it could be with pistons, but they haven't confirmed/denied anything. And pistons don't take up that much CPU

 

Indeed, but it really is impossible right now.

 

Yeah that's what I was saying. :3

 

It would be maaaaaaaybe sort of possible but the motion would not be smooth and definitely not what you had in mind. Since the sign is adhering to the air block behind the entity as opposed to being attached to the entity (which is how I would do it, as you cannot put a sign on an entity), you would get very jerky motion and it would likely be slow as balls. It's probably just not a good idea.
