Detecting collisions

How I can detect collisions with entity?

 

attack function i think

 

I need check collisions on simple move... Not for damage

My Task: If I collide a player or other entity, then his health decreases.

 

My temprary solution:

PHP:

$axis = new AxisAlignedBB($player->getX(),$player->getY(),$player->getZ(), $player->getX(),$player->getY()+1,$player->getZ());
        $entities = $world->getNearbyEntities($axis);

        foreach ($entities as $entity) {
            if ($entity instanceof Human) {
                    $player->sendMessage('COLLIDE: ' . $entity->getId());
            }
        }

 

The intersectsWith function in AxisAlignedBB.php should be your solution
