Entity I/O

Namespace: DeadworksManaged.Api

Hook into the Valve entity I/O system to observe output firings and input dispatches by entity designer name.

EntityIO

Hooking Outputs

Subscribe to outputs fired by entities with a given designer name:

var handle = EntityIO.HookOutput("trigger_multiple", "OnTrigger", ev =>
{
    Console.WriteLine($"Trigger fired by entity {ev.Entity.EntityIndex}");
    Console.WriteLine($"Activator: {ev.Activator?.Classname}");
});

// Cancel later
handle.Cancel();

Hooking Inputs

Subscribe to inputs dispatched to entities:

var handle = EntityIO.HookInput("func_button", "Kill", ev =>
{
    Console.WriteLine($"Kill input received by {ev.Entity.Classname}");
    Console.WriteLine($"Value: {ev.Value}");
});

Methods

Method	Returns	Description
HookOutput(string designerName, string outputName, Action<EntityOutputEvent>)	IHandle	Subscribe to outputs by designer name and output name
HookInput(string designerName, string inputName, Action<EntityInputEvent>)	IHandle	Subscribe to inputs by designer name and input name

Both return an IHandle that cancels the hook when disposed or cancelled.

Limited Entity I/O Support

Entity I/O hooks work with map-placed entities that use the Source 2 I/O system (e.g. trigger_multiple, func_button). Player entities ("player") do not fire standard I/O outputs like "OnDeath" — use OnTakeDamage or GameEvents.AddListener("player_death") instead for player death detection.

EntityOutputEvent

Data for a fired entity output.

Property	Type	Description
Entity	CBaseEntity	The entity that fired the output
Activator	CBaseEntity?	The entity that activated the output
Caller	CBaseEntity?	The entity that called the output
OutputName	string	Name of the output (e.g. "OnTrigger")

EntityInputEvent

Data for a received entity input.

Property	Type	Description
Entity	CBaseEntity	The entity receiving the input
Activator	CBaseEntity?	The activating entity
Caller	CBaseEntity?	The calling entity
InputName	string	Name of the input (e.g. "Kill")
Value	string?	Optional string value passed with the input

AcceptInput

You can also fire inputs directly on entities. See Entities:

entity.AcceptInput("Start", activator: null, caller: null, value: "");
entity.AcceptInput("Kill", activator: null, caller: null, value: "");
