Archetype Entity

Overview

An Archetype Entity is based on a regular Entity and specifies individual parameter values for that Entity. If the value of an Archetype parameter is changed, all instances of that Archetype in the scene will be updated automatically.

Archetype Entities are organized in libraries which can be created in The DataBase View.

So technical level designers can predefine variations of Entity classes as Archetype Entities that can be used throughout the whole game. For global changes affecting all instances, the Archetype Entity just needs to be changed once in the Database View.

Placing Archetype Entities

Archetype Entities can be accessed by using RollUpBar -> Objects -> Archetype Entity or alternatively, they can be dragged directly from the DataBase View.

The browser window in the RollUpBar shows all the Archetype Entity libraries that are currently loaded for the level.

Navigate these libraries by clicking once. Drag the individual Archetype Entities to the level to place them.

Filter of Archetype Entity Browser

This filter specifies a search string for the currently loaded Archetype library. All libraries containing Archetype Entities appropriate for the search string will be shown upon pressing the Reload button. Also, the Reload button can be used to update any recently altered archetype library files.

Archetype Entity Object Properties

Once you have placed an Archetype Entity in the level, select it to view its properties.

EntityArchetype Params

EntityArchetype Params are a basic set of parameters shared by all Archetype Entities.

EntityArchetype Properties2

Below is an example of the EntityArchetype Properties2 dialog box. This dialog box contains a selection of properties from the Entity type, allowing you to edit the Archetype Entities on a case by case basis.

The example below shows the properties2 set for an AI entity:

Creating Archetype Entity Libraries

Archetype Entity Libraries can be created and configured in the The DataBase View.

Difference between Archetype settings and script defaults

Every highlighted property in the database view has actually a different value than the script default.

Revert to Script Defaults

To revert the Archetype setting back to the actual script default value you can right click on a property and choose Revert to Script Default.

Checking the Script Default value

It is possible to check the default value in the entities script by hovering over the property.
