Sneak/Sprint

How can I set a player sneaking/sprinting
And how can I chck if a player is sneaking/sprinting?

If you need check anyone sprinting/sneaking
This for sneaking

PHP:

Public function onSneak(PlayerToggleSneakEvent $ev){
   $this->getServer()->getLogger()-($ev->getPlayer()->getName()."is sneaking");
}

This for sprinting

PHP:

Public function onSprinting(PlayerToggleSprintingEvent $ev){
   $this->getServer()->getLogger()-($ev->getPlayer()->getName()."is sprinting");
}

why are you trying to subtract a string from a logger object?
Moreover, toggle means "toggle on/off".

I don't know if this still works but this is how it was before sneaking was added to MCPE.

PHP:

//Add entity flag
//Add sneaking flag
$player->setDataFlag(Entity::DATA_FLAGS, Entity::DATA_FLAG_SNEAKING, true);//true = on, false =  off
//Add springting flag
$player->setDataFlag(Entity::DATA_FLAGS, Entity::DATA_FLAG_SPRINTING, true);//true = on, false =  off

//check if player is sneaking/sprinting
if($player->isSneaking()){
//player is sneaking
//do something...
}
if($player->isSprinting()){
//player is sprinting
//do something...
}

Thanks

PHP:

Public function onSprinting(PlayerToggleSprintingEvent $ev){
   $this->getServer()->getLogger()->info($ev->getPlayer()->getName()."is sprinting");
}

PHP:

Public function onSneak(PlayerToggleSneakEvent $ev){
   $this->getServer()->getLogger()->info($ev->getPlayer()->getName()."is sneaking");
}

Fix
----------------

PHP:

$player->setSneaking();
$player->setSprinting();
