Entity I/O

Provides:

Equivalent to Hammer I/O system (FireOutput / AcceptInput).

Header source2mod/schema/entityio.h

`InputData_t`

Data passed to inputs.

Field	Type	Description
`pActivator`	`CBaseEntity*`	Entity that triggered the input
`pCaller`	`CBaseEntity*`	Entity owning the output
`value`	`variant_t`	Passed value
`nOutputID`	`int`

Interface for listening to entity outputs.

virtual Action OnEntityOutput(const char* pchOutputName, CEntityInstance* pActivator, CEntityInstance* pCaller, float flDelay, bool post);

Called when an entity fires an output.

Parameter	Type	Description
`pchOutputName`	`const char*`	Output name (e.g. "OnTrigger")
`pActivator`	`CEntityInstance*`	Activator entity
`pCaller`	`CEntityInstance*`	Caller entity
`flDelay`	`float`	Delay before execution
`post`	`bool`	false when called before the output fires, true after

Returns Action — Action (Action::Ignore / Action::Override / Action::Supersede)

Listener bound to a specific entity.

Inherits IEntityIOListener

Field	Type	Description
`m_pTarget`	`CEntityInstance*`
`m_Callback`	`std::function<Action(const char, CEntityInstance, CEntityInstance*, float, bool)>`	Callback handler

CSingleEntityIOListener(CEntityInstance* target, std::function<Action(const char*, CEntityInstance*, CEntityInstance*, float, bool)> cb);

Action OnEntityOutput(const char* outputName, CEntityInstance* pActivator, CEntityInstance* pCaller, float delay, bool post) override;

RAII handle for entity output listeners.

Automatically unregisters listener on destruction.

void Unhook();

Removes listener.

Stores listeners per output.

Field	Type
`m_vecPre`	`std::vector<IEntityIOListener*>`
`m_vecPost`	`std::vector<IEntityIOListener*>`

Key for output lookup.

Field	Type
`m_szClassName`	`std::string`
`m_szOutputName`	`std::string`

Hash function for OutputKey.
