Partner Team Reporting:

Gamemode One

Verification builds and Platforms:

v1.10.0, v1.11.0, v1.12.0, v1.13.0

Regression builds:

Definitely worked in the very early stages of add-ons. It's broken for over two years now though.

Summary:

The minecraft:attack component does not apply potion effects defined under "effect_name" and "effect_duration" correctly if it's used on the player. The "damage" argument works correctly.

Impact:

There's no clean work-around available. Removes the ability to add more unique custom item behavior by editing player behavior.

Repro Steps:

• Download the attached BP and apply it to a world
• Join the world and attack an entity
• Observe the result

Observed Results:

The attacked entity does not receive the poison effect

Expected Results:

The attacked entity receives the poison effect
