[2024.4]Epic Core API Plugin

I created this plugin to provide convenient and powerful entity manipulation APIs for MCreator developers. Although I rarely use MCreator to create mods anymore, I still want to help those who continue using MCreator and struggle with entity-related operations.

This plugin integrates Epic Core API as a dependency and provides several entity manipulation procedure blocks that would otherwise be difficult or impossible to implement in vanilla MCreator.

Features

• Force Kill Entity - Instantly kill an entity with proper damage source handling
• Force Set Health - Set entity health using multi-phase smart modification
• Force Revive - Revive dead entities by clearing death state
• Set Invulnerable - Toggle strong invulnerability with automatic health locking
• Force Remove Entity - Completely remove entities with deep cleanup

All procedure blocks are located in the "Epic Core API" category (purple) in the procedure editor.

Additionally,ECA unlocks vanilla attribute limits to ±Double.MAX_VALUE by default.

Requirements

• MCreator 2024.4
• Minecraft Forge 1.20.1
• Epic Core API Dev JAR (for development)
• Epic Core API Mod (runtime dependency for players)
