+# Miscellaneous Coding Tricks
+
+This article will cover a handful of miscellaneous coding tricks that you could do in the game, largely thanks to the framework Funkin' was built on - HaxeFlixel. 
+
+Most of these are recommeded to be used with [Modules](01.ScriptedModules.md), so it is recommended that you familiarize yourself with them beforehand.
+
+## Activating something only on game launch
+
+As of 0.8.0, the `onCreate` function on Modules gets dispatched on hot-reloading, alongside getting dispatched after everything in the game was initialized. This could potentially break a couple of things that the programmer wanted to only be activated once, on game launch. Luckily, Flixel provides a signal for this - `FlxG.signals.postGameStart`, which gets dispatched after everything in the game's initialization state gets created. 
+
+You could use it as follows:
+
+```haxe
+import flixel.FlxG;
+import funkin.modding.module.Module;
+
+// ...
+
+class IntroModule extends Module
+{
+    var isInIntro:Bool = false;
+
+    public override function new()
+    {
+        super("IntroModule", 0);
+
+        // add a signal that only gets dispatched in the once in a play session
+        FlxG.signals.postGameStart.addOnce(function()
+        {
+            isInIntro = true;
+        });
+    }
+
+    public override function onCreate(event:ScriptEvent)
+    {
+        if (isInIntro)
+        {
+            // add some code here
+        }
+    }
+}
+
+```
