NautilusTrait 5.46.0

trait · pocketmine\entity\aquatic\NautilusTrait · source

Taming equipment and riding shared by the nautilus and the zombie nautilus (nautilus.json, zombie_nautilus.json):

• Inventory: a HorseInventory ("horse" container) with the saddle in slot 0 and nautilus armor in slot 1, opened by sneaking and using a tamed adult or with the inventory button of its rider (vanilla). Saddles and armor are also put on by using them on a tamed adult; shears take the armor off first, then the saddle (one use each, only while nobody rides it). Nautilus armor protects like horse armor (copper 4, iron 5, gold 7, diamond 11, netherite 19) and is shown to viewers in the body slot of MobArmorEquipmentPacket. Saved as "ChestItems".
• Riding: one player seat 0.925 up (third person camera 7 blocks away). Once saddled, the rider steers it: in water with free camera controls (WASD_FREE_CAMERA_CONTROLLED: forwards follows the camera pitch, strafing at 0.7x, backwards at 0.5x, up to 6.5 blocks per second), out of water like a ground mount (WASD_CONTROLLED, 0.88 blocks per second). Holding then releasing jump dashes (CAN_DASH, HAS_DASH_COOLDOWN, 2 s cooldown) in the rider's look direction: vanilla dash_action momentum 154 in water and 42 on land times the player-controlled movement (0.015), 0.1 up. A rider in water breathes (vanilla underwater_mount_breathing; Breath of the Nautilus is not sent).

The using class implements \pocketmine\entity\riding\MountInventoryHolder, provides isTamed(), NautilusTrait::isInWaterForRiding() and NautilusTrait::swimTowards(), and calls NautilusTrait::initNautilusInventory(), NautilusTrait::saveNautilusInventory(), NautilusTrait::tickNautilus() (entityBaseTick), NautilusTrait::handleDashInput() (handleRiderInput), NautilusTrait::interactWithEquipment() and NautilusTrait::syncNautilusData().
