+    Simple example for decoding input as actions, allowing remapping of input to different keys or gamepad buttons.
+    for example instead of 
+        IsKeyDown(KEY_LEFT)
+    you'd use
+        IsActionDown(ACTION_LEFT)
+    which can be reassigned to e.g. KEY_A and also assigned to a gamepad button. the action will trigger with either gamepad or keys
