Racetrack? *Cringe*

I'm a little reluctant to ask this, but I'm wondering how I'd accomplish the following things:

1. Placing (1st, 2nd, 3rd, 4th, 5th, 6th, 7th, and 8th).

2. One-way blocks (Blocks that only allow you to go SOUTH.)

If I think of more ideas I'll post them here.

 

TheHandfish
1. You can see who has passed certain locations.
2. You can add metadata to blocks, and see if they have it. Then, if it has it and then see what direction the player is looking.




(may not be efficient, or work anyways. It's too late for me to be on here)

 

TryB4:

Okay! I'm actually making a lot of progress.

My race track method: I'm placing different golden blocks with different item datas. They mark the track. The item data increases steadily, so I'll be running along, and while doing so, an event checks to see when I pass one golden block with a value of, say, 2, then I'll go further and pass one with "3". However, the problem I now face is my blocks aren't retaining their item data when placed! Which means if I place a gold block with an item data of 2, it automatically defaults to zero. So I put this code in to set the item data when the block is placed:

Code:javascript

 
    public static void onPlace(BlockPlaceEvent event)
    {    
        Block b = event.getBlock();
        if(b.getType() == Material.GOLD_BLOCK)
        {
            int arg = Integer.parseInt(event.getPlayer().getItemInHand().getData());
            b.setData((byte) arg);
        }
    }
 

I'm getting an error at "b.setData((byte) arg);". Am I writing this wrong?

Thanks.

 

TheHandfish
b.setMetadata("trackPlace", new FixedMetadataValue(this, <number>));

Replace 'this' with your main class

 

I put that with my onPlace method or...?

Because I tried it, putting in a sendMessage so when I walk past blocks it tells me its data.

p.sendMessage("§4Detected golden block! §a" + b.getMetadata("trackPlace"));

But I just get a bunch of confusing phrases, no one number.

TryB4:

To give you an idea of what I'm talking about when I say "confusing phrases":

TheHandfish getMetadata() returns a List<MetadataValue>, not a single object, so when you send the List to the player, it gives them that "confusing phrases"

 

xTigerRebornx:

Ah, thanks.

So maybe I should rephrase my question, LOL

How do I assign a number to a gold block, then when I place it, make it so it retains the number and how do I check that number?

 

TheHandfish
<block>.getMetadata("<taghere>").asInt();

 

TryB4:

I'm getting an error at "asInt()".

Code:

b.getMetadata("trackPlace").asInt();

Bump.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

TheHandfish
b.getMetadata("trackPlace").get(0).asInt();

 

TryB4:

Now I'm getting errors when the onMove event is called. :-/

 

TheHandfish
Whats your player move event look like?

 

TheHandfish
Be sure to check everything, also. Metadata doesn't stay through restarts, so you need to set that everytime.

Code:java

if (block.hasMetadata("trackPlace")){
if (block.getMetadata("trackPlace") != null){
if (block.getMetadata("trackPlace").size()>=1){
if (block.getMetadata("trackPlace").get(0) != null) {
 
}
}
 
}
 
 
}

Here's the full thing.

It only gets important at line 73.

TheHandfish
Alright for debugging purposes simply before you do the b.getMetadata check to see if there is metadata there and if not send a message to your self. Then your problem might be the setting of metadata not the listening part.

 

MCForger:

I did so, and it said it doesn't have metadata... hmm...

 

TheHandfish
Did this occur after a restart/reload?

 

MCForger: Wait, now it's coming up positive. Let me do some more testing, one sec.

EDIT: I did it... I DID IT! YAY!

The numbers are returning like they should, now!

Thanks so much for your help, MCForger and TryB4!

 

TheHandfish
No problem.

 

MCForger, TryB4,

Is there a way to save the blocks with their meta data when the server closes?

 

TheHandfish
You can save the block's location to a configuration file.
And the metadata/value too.

 

TryB4: How would I go about that? (Sorry for so many questions... x_x)

 

TheHandfish
First create a configuration file.
http://pastebin.com/BZVT0qWR
in your main class:
public static storage s;

in onEnable:

s = new storage();
s.setup(this);

Then you can save it in there.
