![]() Step 7) Press play button and check the outcome Step 6) Keep the spheres at some distance above the plane and let gravity affect the balls on play Step 5) Take a plane and create a Physics Material as per requirement Step 4) Attach Rigidbody to the spheres (this will show that it is an physics object) Step 3) Attach it to sphere collider physics material Step 2) Create Physics material and reduce the friction amount to 0 and set bounciness to 1, and set bounce combine to maximum Keep them at some distance from each other Let’s understand this better with the following example But do take care if you will reduce physics calls too much, you might not get proper physics." Then it’s better to reduce the number of calls made to the Physics Engine. "If you are going to make a simple card game, which has not much to do with physics. You need to play around with its value to get the ideal result. All FixedUpdate() will also be called every 20ms.īut if your game is not heavily dependent on physics, you can always increase the TimeStep to get better results. “A framerate-independent interval that dictates when physics calculations and FixedUpdate() events are performed.”ĭefault value is 0.02 (in seconds), this shows that every 20ms Physics Update will be executed. So let’s get going! Fasten your seat belts as this is going to be a long but enjoyable journey. I am not going to talk about how to work with physics in Unity, rather I’ll list out tips and points on how to optimize your physics, so if you are a beginner I would first advise you get an overview of Unity physics.Īs Physics is a very, very, very, very (Running out of very s :P ) huge and wide concept, I have decided to divide into different parts and simplify as much as possible. So I have decided to write this post and hence, help you to skip the pain of this learning phase, and become a pro physics developer! It took me almost a year to note down the key points to keep in mind while dealing with physics. ![]() People can debate by saying, “Good physics needs a very fast CPU!”īut trust me it’s not always true! Most of the times proper physics can be attained by diving deep into the sea of Unity! And by learning how exactly does it work.Įarly on as a fresher I had to deal with 100’s of things with physics. It’s true that physics is the most difficult and important part of game development process and there is no hiding from it! It’s not just about wrong physics it’s all about proper lag free smooth gameplay.Īnd this is something that cannot be easily attained. Wrong or improper physics can drive away potential gamers. But then you finally sat and started working on the tricky part, "THE PHYSICS"!Įverything seems to be falling apart you come across low FPS, weird movement, issues regarding collision/triggers, High CPU usage and what not. Imagine a case where you finally decided to come up with something big! Something noteworthy! Something with loads of realistic physics and graphics! A big game with everything at stake!ĭesign is created, structuring is done, and everything looks in order. Physics may not be everyone’s favorite subject, but the truth is that Physics plays a very important role in development of the game industry. Yes, Yes I know! We all blame that apple! Why it had to fall on that very day, and that too on Newton’s head? Why God why? There is no end to questions list when it comes to physics, and it’s obvious that you might have many more questions like these. Why do I see drops in frame rate? Is it physics or something else? What things should I take care of before starting with game physics? What controls do I have over Unity Physics?
