Commands/damage

Applies damage to the specified entities.

Usage
This command is not to simply change entities health value. Instead, it directly calls the underlying logic in the game to simulate the situation of causing damage to the entity. So this command has many undefined behaviors.

The output text, result, and return value of damage command are not related to whether the health value is changed. In fact, they are undefined.

The  is not the final amount of reduced health value. The reduced health value is usually less than or greater than the  due to world difficulty, armors, status effects, or the target entity itself, etc.

When damaged, the entity may react accordingly, such as being knocked back, becoming angry, etc. The damager entity may also react in certain ways, such as the arrow's disappearing.

'''Undefined behaviors may be changed at any time without warning. When this happens, your addons or maps may cease to work. Use these undefined behaviors at your own risk.''' {{Collapse
