Generating World then SetBlock

Hello, I am currently trying to generate a world then set a block. I have it where when a new player joins It generates the world, but It does not setBlock (Not supposed to). Now when the new player does /is go for the first time it is supposed to setBlock, yet it doesnt. Here is my Code

PHP:

/* Generate one Bedrock Block */
$level->setBlock(new Vector3(0, 100, 0), BlockFactory::get(Block::BEDROCK));


 

Is the world loaded?

 

Create custom generator with populator insteadof placing block after generating.

 

The problem is when you create a new world, the world is surely "loaded" but not "generated".
The generation task runs asynchronously and will override your setBlocks.

Code:

$level->generateLevel(...);
// ^ will also call $level->populateChunk(all spawn chunks);
$level->setBlock(...); // run by you
// an uncertain amount of time later
// pmmp $level->setChunk(populated chunks); <-- this overrides the blocks

You could do what @GamakCZ said, that's the simplest way to go with this. Or you could create an async event which calls back once all loaded chunks of the level are populated.

 

ive never worked with populating levels. Do you know any examples maybe i can look at?
