Solved Add skylight on sapling

Hello, I want to do a function that would make underground trees grow normally but I have no idea how to do it. If you know how to solve this problem, write in advance thanks.

 

It would still grow if you put torches around such that the light level is more than 7.
If you want it to grow regardless of light level you would have to extend Sapling, override onRandomTick and register it

 

Something like this?

PHP:

<?php

namespace TreeFix;

use pocketmine\block\Sapling;

use pocketmine\level\generator\object\Tree;
use pocketmine\math\Vector3;
use pocketmine\Server;
use pocketmine\utils\Random;

class TreeFix extends Sapling
{

    public $x;
    public $y;
    public $z;

    public function onRandomTick() : void
    {
        if ($this->level->getFullLightAt($this->x, $this->y, $this->z) >= 8 and mt_rand(1, 7) === 1) {
            if (($this->meta & 0x08) === 0x08) {
                Tree::growTree($this->getLevel(), $this->x, $this->y, $this->z, new Random(mt_rand()), $this->getVariant());
            } else {
                $this->meta |= 0x08;
                $this->getLevel()->setBlock($this, $this, true);
            }
        }
    }
}

when i try this i got that error:

Error: "Call to a member function getFullLightAt() on null" (EXCEPTION) in "plugins/TreeFix/src/TreeFix/TreeFix" at line 20

 

You can remove that line actually since you dont need to check the light , just leave the mt_rand there, you dont need the public xyz too

 

i got a new error:

TypeError: "Argument 1 passed to pocketmine\level\generator\object\Tree::growTree() must implement interface pocketmine\level\ChunkManager, null given, called in C:\Users\aspon\Documents\Minecraft\Server\plugins\TreeFix\src\TreeFix\TreeFix.php on line 18" (EXCEPTION) in "src/pocketmine/level/generator/object/Tree" at line 55

code:

PHP:

<?php

namespace TreeFix;

use pocketmine\block\Sapling;

use pocketmine\level\ChunkManager;
use pocketmine\level\format\Chunk;
use pocketmine\level\generator\object\Tree;
use pocketmine\math\Vector3;
use pocketmine\Server;
use pocketmine\utils\Random;

class TreeFix extends Sapling
{

    public function onRandomTick(): void{
        Tree::growTree($this->getLevel(), $this->x, $this->y, $this->z, new Random(mt_rand()), $this->getVariant());
    }
}

 

Did you do anything else? I can't think of why $this->getLevel() will return null under normal circumstances
Could you show the whole error stack trace?

No you are not supposed to call onRandomTick() yourself
You just need to do BlockFactory::registerBlock(new TreeFix(),true); will do

 

After doing this, nothing crashes in the console but nothing happens in the game, the trees continue to grow underground

 

Isn't that what you are trying to achieve?? For trees to grow underground?

 

i Solved that
