this is, quite literally, EXACTLY what I was looking for. I wanted to make Celeste-esque physics and didn't even have to search specifically for Celeste to find this.
Maddy has made a post on medium about how celeste physics works. It does not work using forces. It uses speed/velocity vectors to calculate movement and exact positions on a tilemap (due to it being pixel art, madeline cannot move half a pixel etc), obviously its a lot more complex than that, but I can confirm it does not use forces as such. The concept is the same however, you do want acceleration and deceleration, but you can achieve it without forces.
@@huseyinakkoc1062 The line of code in question is as follows: csharp copy code float accelRate = (Mathf.Abs(targetSpeed) > 0.01) ? acceleration : deceleration; This line of code is inside a FixedUpdate() function in Unity and is responsible for calculating the acceleration rate (accelRate) based on the target speed (targetSpeed), acceleration (acceleration) and deceleration (deceleration). Next, we will break down the line of code to understand how it works: Mathf.Abs(targetSpeed) > 0.01: This part of the code checks if the absolute value of targetSpeed is greater than 0.01. Mathf.Abs() is a static function of the Mathf class in Unity that returns the absolute value of a number. In this case, you are checking if the targetSpeed is greater than a minimum value of 0.01. This is used to determine if the object should speed up or slow down. ? acceleration : deceleration: This part of the code is a ternary operator that determines the value of accelRate based on the result of the previous condition. If Mathf.Abs(targetSpeed) > 0.01 is true, then accelRate will be equal to acceleration. Otherwise, accelRate will be equal to deceleration. In short, this line of code sets the acceleration rate (accelRate) based on the target speed (targetSpeed). If the target speed is greater than 0.01, the acceleration value is used. Otherwise, the deceleration value is used. Yeah I used ChatGPT
Well, I spent many hours looking for a good and also beginner-intermediate 2D platformer movement system for Unity and finally found this. Now this is a quality content. The video is easy to understand, and the used concepts are really well-explained. Provided github code is well documented and easy to understand with some Unity documentation digging, also great for adapting by using scriptable object for holding movement parameters. I hope you will put here more useful videos like this. :)
Let me just say man, of all the player controllers I've implemented, when I finally got this working, it is by far the best feeling controller I've ever made. I'm more of a Visual Scripting guy so it took me a little time to translate your system here, but DUDE! Thank you so much! This is now going to be my designated method for player movement! You rock!
If you like visual scripting, what you can do is making modular c# code and make specific cisual editors for your use case (I know it's hard, but it's also weirdly fun)
Man, I've been using Unity for quite a long time this is literally the BEST video I've ever seen about platformer movement. Glad youtube showed this on my homepage.
The new input system's so cool! It's not super well implemented in the code right now, but when I get round to adding some new features, I'll try to tidy it all up and make it all fit nicely :D
@@DawnosaurDev and for those who had issues like me implementing the handler and control files and movement scripts, you will need to go into Edit-> Project Settings and then Player and scroll down to the configuration section and change Active Input Handling from New or Old into "Both" in order for the current code to work.
Really nice explained. Many people which program in unity do not realize how important all of these mechanics are and you really explained all. Edit: And the fact that you explained them IN CODE. Dude you need more subs.
Finally someone who truly explains how to make proper player movement instead of making something in 20 minutes and showcasing it! Great video, very useful
I remembered seeing this video 2 times before, and I remembered it was so simple and informative. And today I am making my first game, and I wanted the controls to feel as good as possible, and then I remembered this video. I searched up something like "Video game movement analysis", and I found it!
The quality of the videos. The music and videogame taste. The smooth explaining. There's no reason NOT to be your 500th subscriber! :D Congratulations, underrated tutorial guy! And..well..thanks! XD
yo this is a really nice solution; I've always had an issue with figuring out how to get physics-based movement to not feel so sluggish, and the scaling-force-by-difference-from-target-speed thing you have here seems to work pretty well
a year late, but howly this is EXACTLY what i need. I want to make a snappy movement but I want it to still able to be affected by AddForce. Thanks a lot dude you just gained a subs!!!!
The same tutorials on UA-cam are repeated over and over again, using the same methods, and 99% of them are very basic tutorials. Professional and high-quality tutorials like this are rare and must be supported.
This needs to be said right now... This is the best video ever made on youtube, it is so helpfull and so full of information, i would pay money for this information, because im in need of movement system for my 2D Metroidvania
Hi, thank you for this video. Great to find a different way to move than the usual rb.velocity = ... Also, good to see that you use the new input system. M. D.
I just started developing and designing games 4 months ago, I'm about to tackle my first platformer in the next few weeks as my next project. This is explained so well and i understood 100% of it! I'm so proud to be able to look at the code now and understand what it means and I'm so happy to be at a point where if i do end up copying this code, it wont be blindly copy pasting it. I'm still not at the point where i can come up with things like this myself but i can definitely tweak a few things and understand the effect they have and my reasoning for them. Thank you for making this video! i subbed and I'm looking forward to watching many more of your future videos :)
thanks man. this is awesome. there are so many ways to do this but none of them feel as nice as i would like. I havent tried your way yet but it takes into account a lot of factors that i havent seen considered elsewhere. well done!
this system is FANTASTIC!! 1 question though, wondering if anyone knows. Instead of flipping the Scale on the X (or changing the "FlipX" on the Sprite Renderer) to get the player to turn around, I generally like to use transform.Rotate(0,180f,0) to get the player to turn around. That way, the actual transform.right flips, and so any children of the player also turn around properly (and saves you from having to do multiple checks on both the left and right side) However...implementing this seems to result in a VERY slight (but noticeable) jitter for a frame when the player turns around (only when in the air interestingly) - happens with or without camera follow. I'm looking for the smoothness you get from flipping the Scale on the X, but the functionality of changing the transform.right. And I don't really want to interpolate the rotation as this produces a Paper-Mario-like effect. Any ideas anyone? EDIT: solved. This seemed to be a problem when my character was in the air only (gravity using RB, therefore physics simulation) - and since I was checking for this rotation change in update, the physics vs the transform change were fighting each other that frame, resulting in the jittery motion. So the fix, IF you are wanting to change the player's transform.right directly (instead of faking it by using -1 on the x scale) - is to call the CheckForTurn() function in FixedUpdate, not Update.
I can't believe I missed this tutorial. I used to see this video pop up a lot but always assumed I'd seen it already. God damn it all. I've been squinting at my player's jump. I've gotten it down using velocity instead of add force, but there was always something off about it. Like it didn't feel natural. And the code to control things like gravity, deceleration and acceleration is really messy with velocity compared to that clean force code. Thank you.
Wow you're insane man. one of the best video I've seen from this subject. Hope you're gonna continue posting some other tuto (yea I know my english is very bad 👀)
This is a very well done tutorial! It covers a lot of ground and gives plenty of code examples for me to replicate. Thank you and keep up the good work!
i always thought i needed to use kinematic and build a whole physics system to be able to make this kind of controller. As i'm making a small project (which is basically a celeste rip-off let's be honest) this video is helping me, and will help me get a better understanding of unity physics system. you are too kind. Thanks man. i mean it.
God damn, what a video. Coding noobs are only able to experience the creative joy of game development because of amazing content like this - thank you!
Please keep making great videos like this one! They are well-edited, concise, and pack a lot of useful information in a short amount of time! Also, you explain things incredibly well!
Wow. This video is very well made and informative. Congrats dude! For some feedback, I would suggest adding some diagrams when explaining the coding parts to break up some of the visual monotony. The video flows super well, while keeping a steady pace. Subbed, fantastic job!
This is so awesome! I've been looking for a way to create a 2D platform character controller that works with Physics for a long time but just couldn't seem to find any good tutorials or examples online. I downloaded your project and was so happy at how clean and tidy the code and the scene are! Thank you so much for the amount of work you put into this! Have you thought about creating a step-by-step tutorial on how you created the code for the playerMovementImproved script?
Just realized that I never left a comment on here, anyways, this video is amazing! Everything is explained very well and the visuals really helped to explain the code. Thank you.

Your video is so good that I managed to use your solution for 3D, as well as adapt your code to have momentum like Sonic games!
May I ask how you converted the Run method into 3D? I tried to, but it caused the character to accelerate exponentially out of control.
