Cancel Suffocation

How to Cancel Suffocation in a Wall?
Or drowning in water?
Sorry for the bad english

PHP:

use pocketmine\event\entity\EntityDamageEvent;
public function onDamage(EntityDamageEvent $e){
if($e->getCause() === 3){//suffocation
//do something
}
}

$e->setCancelled();

or $e->setDamage(0), which will not damage the player.

which is drowning?

is the same as suffocation

Code:

const MODIFIER_BASE = 0
const MODIFIER_ARMOR = 1
const CAUSE_CONTACT = 0
const CAUSE_ENTITY_ATTACK = 1
const CAUSE_PROJECTILE = 2
const CAUSE_SUFFOCATION = 3
const CAUSE_FALL = 4
const CAUSE_FIRE = 5
const CAUSE_FIRE_TICK = 6
const CAUSE_LAVA = 7
const CAUSE_DROWNING = 8
const CAUSE_BLOCK_EXPLOSION = 9
const CAUSE_ENTITY_EXPLOSION = 10
const CAUSE_VOID = 11
const CAUSE_SUICIDE = 12
const CAUSE_MAGIC = 13
const CAUSE_CUSTOM = 14

You can use if($e->getCause() == EntityDamageEvent::CAUSE_SUFFOCATION or just 3

@MyNameIsTriXz thanks

if($e->getCause() === EntityDamageEvent::CAUSE_SUFFOCATION);

Don't take the constant 3. It might be changed in the future. Always use the constant reference.

Oh, forgot to write that, dont think I didnt know that
