Arma Reforger:Scripting Conf File Usage

Sometimes, a .conf file can be useful in order to store multiple settings/values that would otherwise be flooding a class' member variables.

Two main approaches exist to refer to a .conf file:

ResourceName Approach	Object Approach
a default value is possible Big setup No data preview	Quick setup Data preview and creation on the fly a default value is not possible

The following examples assume a .conf file is to be used in a custom entity.

[EntityEditorProps(category: "GameScripted/Misc")] class SCR_ExampleEntityClass : GenericEntityClass { } class SCR_ExampleEntity : GenericEntity { // config will be used here }

ResourceName Approach

The simplest course of action is to target the wanted .conf file with a ResourceName path:

class SCR_ExampleEntity : GenericEntity { protected ResourceName m_sConfig = "{EAD206A79A774696}Configs/EntityCatalog/FactionLess/EntityCatalog_Characters.conf"; }

A proper way to make things easy is to have this property as an attribute:

class SCR_ExampleEntity : GenericEntity { [Attribute(defvalue: "{EAD206A79A774696}Configs/EntityCatalog/FactionLess/EntityCatalog_Characters.conf", params: "conf")] protected ResourceName m_sConfig; }

At this point, any config file can be used. This is not what is wanted here. Hopefully, the Attribute can be made to target the specific config type we want:

class SCR_ExampleEntity : GenericEntity { [Attribute(defvalue: "{EAD206A79A774696}Configs/EntityCatalog/FactionLess/EntityCatalog_Characters.conf", params: "conf class=SCR_EntityCatalogMultiList")] protected ResourceName m_sConfig; }

With this done, the entity now either has a path to a config, or an empty path. Remains here to load this config, cast it to make sure of its content - requiring a dedicated method:

class SCR_ExampleEntity : GenericEntity { [Attribute(params: "conf")] protected ResourceName m_sConfig = "{EAD206A79A774696}Configs/EntityCatalog/FactionLess/EntityCatalog_Characters.conf"; SCR_EntityCatalogMultiList LoadConfig() { if (m_sConfig.IsEmpty()) return null; Resource resource = Resource.Load(m_sConfig); if (!resource.IsValid()) return null; return SCR_EntityCatalogMultiList.Cast(BaseContainerTools.CreateInstanceFromContainer(resource.GetResource().ToBaseContainer())); } }

Object Approach

This way is faster to setup, but disallows a default value:

class SCR_ExampleEntity : GenericEntity { [Attribute()] protected ref SCR_EntityCatalogMultiList m_Config; }

This method makes the Config field void of any data, but allows to either click the "set class" button to create a config on the fly or to drag and drop a .conf file to fill the field instantly.
