Unity - Secret Tips

Here are some Unity3d tips that commonly slip through the radar.
📌 Scale your project correctly. It's important to have gravity and physics respond realistically when you have rigid bodies colliding or falling with gravity.
📌 Scale your 3d assets correctly. Chaos emerges if every 3d model imported needs to be scaled to a custom size in Unity. Ideally, assets should be scaled to 1, but with exceptions of course.
📌 Avoid Reflection. GetComponent, SendMessage, and Invoke are handy but not performant. Cache the result of GetComponent and avoid the latter.
📌 Lock your Inspector. Some actions require to keep an inspector window open while selecting other game objects, this can be accomplished by tapping the padlock in the upper right corner.
📌 Expose variables in your scripts using SerializedField instead of making everything public.
📌 Reverse an animation by setting the speed to -1 in the AnimationController state.
📌 Write your Gizmos inside your custom scripts. This may display the field of view and range for an AI-controlled enemy.
📌 SerializeField List<> will show in the inspector. I still recommend arrays for the default case, but if your container is going to change size over time, try using a List<>.
📌 Create your own class to manage time. Whether it's pausing, resuming, or slow motion, having a single class that controls Time.timeScale changes will make everything easier.
📌 Master the difference between Awake() and Start(). Awake() is invoked before Instantiate() returns and Start() will be called later during the frame after Awake() is called on everything else.
