Links

Encode URLs (www, http, https) as clickable links or create hyperlinks with custom text.

You can use PubNub's functionality via Blueprints or directly in C++ code.

• In Blueprints, you can access PubNub from any Widget or Actor. Start by initializing chat using InitChat on UPubnubChatSubsystem. Afterwards, you can use the returned UPubnubChat object reference to call all Chat SDK functions.

Blueprint functions

The Blueprints provided in the documentation show how you can structure your application and may contain utility methods and elements like buttons that are not part of the Unreal Chat SDK and are meant to serve as guidance.

• In C++, you can use UPubnubChatSubsystem as any other Game Instance Subsystem.

  Chat now allows you to call all Chat SDK functions, for example, Chat->GetChannel("my_channel").

Usage in Blueprints and C++

Generic referencing

Channel references, user mentions, and links share the same MessageElement structure with different MentionTarget types.

Method signature

Call AddMention() with MentionTarget of type Url. See AddMention() for details.

Refer to the AddMention() method for details.

Get link suggestions

The message elements listener returns link suggestions along with user mentions and channel references.

OnMessageDraftUpdatedWithSuggestions delegate:

• Fires when the draft content changes
• Provides the current state of message elements (TArray<FPubnubChatMessageElement>)
• Offers FPubnubChatSuggestedMention items suggesting user mentions, links, or channel references

Unlike OnMessageDraftUpdated, which only delivers content changes, this delegate also includes suggestion data for dynamic draft updates.
