Link Opener System

Summary

The LinkOpenerSystem is a utility system designed to handle the opening of URLs within Unity. This system provides an easy way to open web links or deep links that can either be opened in a web browser or directly in a compatible app, depending on the URL provided.

Modules Dependencies

None. One MonoBehaviour, no UGTK reference: it can be used independently.

Setup

To set up the LinkOpenerSystem, follow these steps:

Setting Up the Link Opener

Technical Info

The following is the main script and workflow of the LinkOpenerSystem.

Scripts:

Mn_LinkOpener: The core component of the system, which contains the logic for opening URLs. It checks if the URL is empty before attempting to open it, and it logs a warning if the URL is not set.

Good to know:

Application.OpenURL behaves differently on every platform. On desktop it hands the URL to the default browser; on mobile it leaves your app (and on iOS a mailto:/tel:/custom scheme with no installed handler simply does nothing); on WebGL it is a popup, so the browser can block it unless it happens inside a real user click — which is exactly what a Button gives you. Do not call it from Start or from a timer on WebGL.
Deep links need the scheme registered by the target app. instagram://user?username=... only works if Instagram is installed: there is no callback telling you it failed, so pair it with a web fallback if it matters.
An empty URL only logs a warning — nothing opens, nothing throws.
The prefabs: LinkOpenerButton is the generic one, Instagram a ready-made deep-link example.
