Solved Changing the text on a Sign

Hi,

I am working on a Sign plugin that would lets me show dynamic text there. So I think I got the mechanics right. (getTileEntities, get the Sign object and then do setText...)

My question is how do you fill the text in the sign? i.e. how many characters can I put on each line? I read somewhere that the amount of text depends on the width of the characters. So, how do you calculate this?

Any ideas?

$sign = $event->getPlayer()->getLevel()->getTile(new Vector3($block->getX(),$block->getY(),$block->getZ()));
$sign->setText("line 1","line 2","line 3","line 3");

This is an exemple for blockBreakEvent/place/touch/ or others event with block.

That is not what I am asking for. My question is:

Line1: How much text can you put here?
Line2: How much text can you put here?
Line3: How much text can you put here?
Line4: How much text can you put here?

It depend of the letters and it you write on italic or bold, we can't calculate it beacause of so many posibilities.

@iksaku says:
Once a player have spawned in the world, you can use:

PHP:

$signs = [];
foreach($level->getTiles() as $tile){
    if($tile instanceof Sign){
        $signs[] = $tile;
    }
}


Now you have all the signs available in that world... time to do whatever you want :3
For line lenght.... Just test and keep testing xD

It's like guess and check.

Take a look at TextWrapper.php in the PocketMine src.

Or just pass $block instead of a new Vector3. $block instanceof Vector3, so passing it directly is OK.

I pretty believe that a chunk far from the player won't be loaded. Why don't you just listen to ChunkLoadEvent?

Thanks, that is what I was looking for!

I think the line lengths are 16 characters, and colour codes count as characters.

chek the source of SignModifier

Why?

Text Say All

It says do this, it doesn't say why.

The question in this thread (from April) is:

Which already been answered.
BTW, My plugin, GrabBag has had the feature to change the text of existing Signs for quite some time already (from v1.4.0 from April 16).

So this thread has been "solved". How do I add such prefix to this?

Edit the title of the thread

That doesn't work here.
