The `type` field will have one of the following values: `set_hp`: A mod or the engine called `set_hp` without giving a type - use this for custom damage types.. `punch`: Was punched. `reason.object` will hold the puncher, or nil if none. `fall`, `node_damage`: `damage_per_second` from a neighbouring node. `reason.node` will hold the node name or nil. `drown` `respawn`. Any of the above types may have additional fields from mods. `reason.from` will be `mod` or `engine`. `modifier`: when true, the function should return the actual `hp_change`. Note: modifiers only get a temporary `hp_change` that can be modified by later modifiers. Modifiers can return true as a second argument to stop the execution of further functions. Non-modifiers receive the final HP change calculated by the modifiers.
