From 7ec4bf7c73869fbf641dd642d8e413afc2e0a829 Mon Sep 17 00:00:00 2001 From: Danny Holman Date: Mon, 14 Oct 2024 21:04:19 -0500 Subject: core: mod: create a mod interface Create a skeleton mod interface so that the engine can load shared libraries or DLLs as in-game mods. The API should be compiler agnostic as much as possible.
