PVPPracticeBot v1.2 – Bugfix Changelog

🐛 Bug Fixes

/pvpbot spawn crashing silently

• PVPBot.setAttributes() called zombie.getAttribute(...) with no null check. On Paper 1.21+, attribute lookups inside the World.spawn() consumer can return null before the entity is fully initialised, causing an NPE that swallowed the whole spawn. All four attributes (MAX_HEALTH, MOVEMENT_SPEED, ATTACK_DAMAGE, KNOCKBACK_RESISTANCE) are now null-checked.

Immortality toggle crashing

• PVPBot.setImmortal() had the exact same null-deref pattern on MAX_HEALTH and KNOCKBACK_RESISTANCE. Fixed with the same null-safe setAttribute() helper.

Combat AI NPE after bot is spawned

• executeEasyAI() and executeMediumAI() called entity.getTarget().damage(...) without checking if getTarget() returned null. If a target player logged off or died between ticks, this threw an NPE mid-combat. Both now guard with if (t != null) before dealing damage.
