Object Management

This page explains how object scripts are created, registered, managed, and destroyed dynamically on the client.

Utility Objectify includes a powerful system for managing object script instances tied to entities in the world.

When entities are spawned or unspawned, the framework dynamically creates or destroys script instances based on model-to-class mappings. This allows for automatic behavior assignment and modular logic.

🧠 How It Works

OnRender

When an entity becomes visible to the player:

1. Its model is checked against registered scripts.

2. A new instance of the class extending BaseEntity is created for each script (main and any plugins).

3. Is added to the global 🧠 Entities Singleton list.

4. Lifecycle methods (OnAwake, OnSpawn, AfterSpawn) are called.

5. The instance is stored and tracked.

OnUnrender

When the entity is no longer visible:

• OnDestroy is called on each script.

• It remove itself from the 🧠 Entities Singleton list

• All associated script instances are destroyed.

• Object memory is freed.

This logic is handled via internal UtilityNet events:

UtilityNet.OnRender(...)       -- Creates script instances
UtilityNet.OnUnrender(...)     -- Destroys script instances

📦 Temp Object Properties

Before the object is rendered, properties set during Hooks are stored in a temporary table:

self.someData = 123

These are stored and later injected to the real instance when the object is rendered. This ensures that Hooks can prepare data even before the object is visible, like creating a blip at the entity coords

Hooks and Hooks

can interact only with the temporary instance properties, not real instance runtime changed properties. have access only to:

Name	Description
self.id	The uNetId (UtilityNet id) of the current entity
self.state	The object state bag, read-only (client)

All other hooks (OnSpawn, OnDestroy, etc...)

can interact with the temporary instance properties, as they will be injected before the OnAwake hook

</> API Reference

IsObjectScriptRegistered(model, name)

Checks if a specific model as a script registered to im, can be useful if a plugin needs another plugin to work properly

RegisterCustomHook(hookMethod, hookData)

See 🪝 Custom Hook System

GetObjectScriptInstance(obj, name, nocheck?)

Fetch a specific script instance by name from an object. All main scripts are exposed as main

• nocheck = true skips rendering checks.

GetExternalObjectScriptStatic(model, name)

Returns the raw script table (class) without creating an instance.

⚠️ This is unsafe for live operations, use for inspection only.

AreObjectScriptsFullyLoaded(obj)

Returns true if all scripts have been fully created and attached to the object.
