TOP DOWN MOVEMENT 2D IN UNITY 🎮 | How to Make Top Down Movement in Unity | Learn Unity For Free

[@funkix60]

Hi ! This is a great vid thanks ! No offense, but your code looks very complicated and can be refactored a lot using Vector2().normalized method. Void FixedUpdated() { rb.velocity = new Vector2(inputHorizontal, inputVertical).normalized * walkSpeed ; } With this, no need to set up a speed limiter since is Always returns a vector with magnitude of 1. Meaning Diagonal movement get 1 * walkspeed. Plus, no need to check IF key is pressed since Input.GetAxisRaw will be 0 to 1 so if no key is pressed nothing in happening anyway right? Good day to you good sir :)

[@Dani_Krossing]

You are completely right. 🙂 Looking back I would have done it that way too. I’ll pin your comment for others to see. 😊

[@jehriko7525]

I just want to say I've been struggling with this for a while and this video has helped me immensely, thanks for making it!

[@twist22]

Thanks so much for this! I've been agonizing over using the animator visual representation with transitions and all that jazz and my head's been spinning over a bug I couldn't figure out. I reworked in code and the whole thing feels way simpler now. Thank you! :D

This helped so much! Thank you!

[@serviceallies]

For any fellow nerds who like to make sure the math is precise: to make sure the diagonal movement speed perfectly matches the regular speed, the correct equation is diagonal movement speed times 0.707106. So even .7 is pretty darn close

[@JustinDunn_IT]

Bro, you are completely underrated. The laymen explanations as you go through for why you do something 100% is how I learn. Sure, maybe code can be refactored like @Don't Blink said, buuut for someone like me (with slight coding history) just trying to get off the ground (and understands the first way you do something is not always the optimal) its a godsend for them. So thanks.

[@xavierromeo7781]

Hi ! Thank you really much, you helped me a lot. I reworked your code a little bit to use different idle animations depending on the last direction. I have a direction integer to store the last direction And I use switches and cases instead of a bunch of if-statements.

[@jasminemerritt1831]

Thank you for making this!

[@ph0xnix373]

I really like the way you explain what each line is actually doing. Makes things make a lot more sense. Have you done anything with the new unity input methods? Feel like they streamline the movement process a lot in some other tutorials I found. Just think you do a much better job of explaining what is actually happening and what various codes do.

[@James_GamesYT]

WTH THIS IS SO COOL

[@stealthyshiroean]

Huh, that is different. I originally was going to skip over this video because I already had a working top-down movement controller for my player. However, I wanted to see how you did it and thought it would be good for the learning process. Didn't expect a state machine! I think a lot of tutorials do talk about using the animator and creating blend trees then manipulating those through the code which is pretty much what I did. Also, you did bring up a very important point that I forgot about. My character moves too quickly when walking diagonally lol. I'll need to fix that. Thanks for the great tutorial and the different approach!

[@Mr.Zita1]

Thank you for the courses Mr Dani 🤓👍

[@HullaBiloo]

Hi I was just wondering if there was any way to change it so instead of reverting the player back to the front idle animation you could make it so that the idle animation changes depending on the last input made by the player? Like an Idle_Left animation playing after moving left instead of the player going back to the default and looking down afterwards. Great tutorial by the way!

[@NeosRS]

I have this same question actually, would love to know how to update it to do this.

[@Jonny-op3wr]

Were you able to figure it out? If not he posted a simple solution in another persons comment. It was to make basically idle states for each direction they face and basically do check statements.

[@troyna77]

you would need a variable to "remember" the last state before changing into the new. kindof like a temp/holding variable. then as you exit the loop or code block, perform an if (condition- ex. _tempState == _theStateYouWantToRevertBackTo) THEN {current variable = temp/holding variable}; else (continue without changing animation state); im sure there are a few other more sophisicated ways to handle this.

[@onigiri_sakaro]

if anyone is searching for this, i achieved it by saving a "currentDirection" string when moving and adding 4 Idle States for each direction. i'll post the full code below. hope it helps! :) public class PlayerMovementAnimate : MonoBehaviour { public float moveSpeed; float inputHorizontal; float inputVertical; private Rigidbody2D rb; private Vector2 moveDirection; Animator animator; string currentState; string Player_Idle = "Player_Idle"; string Player_IdleUp = "Player_IdleUp"; string Player_IdleDown = "Player_IdleDown"; string Player_IdleLeft = "Player_IdleLeft"; string Player_IdleRight = "Player_IdleRight"; string Player_WalkUp = "Player_WalkUp"; string Player_WalkDown = "Player_WalkDown"; string Player_WalkLeft = "Player_WalkLeft"; string Player_WalkRight = "Player_WalkRight"; string currentDirection; void Start() { rb = gameObject.GetComponent(); animator = gameObject.GetComponent(); } public void Update() { ProcessInputs(); } public void FixedUpdate() { Move(); } public void ProcessInputs() { inputHorizontal = Input.GetAxisRaw("Horizontal"); inputVertical = Input.GetAxisRaw("Vertical"); moveDirection = new Vector2(inputHorizontal, inputVertical).normalized; } public void Move() { rb.velocity = new Vector2(moveDirection.x * moveSpeed, moveDirection.y * moveSpeed); if (inputHorizontal == 0 && inputVertical == 0) { if (currentDirection == "Right") ChangeAnimationState(Player_IdleRight); if (currentDirection == "Left") ChangeAnimationState(Player_IdleLeft); if (currentDirection == "Up") ChangeAnimationState(Player_IdleUp); if (currentDirection == "Down") ChangeAnimationState(Player_IdleDown); } else if (inputHorizontal > 0) { ChangeAnimationState(Player_WalkRight); currentDirection = "Right"; } else if (inputHorizontal < 0) { ChangeAnimationState(Player_WalkLeft); currentDirection = "Left"; } else if (inputVertical < 0) { ChangeAnimationState(Player_WalkDown); currentDirection = "Down"; } else if (inputVertical > 0) { ChangeAnimationState(Player_WalkUp); currentDirection = "Up"; } } void ChangeAnimationState(string newState) { if (currentState == newState) { return; } animator.Play(newState); currentState = newState; } }

Could you show me how, with this code, I could use the flipped variation of the WalkRight animation as a WalkLeft? My tileset only has right animations for walking and attacking, and death. or would it be easier to just add left animations to my tileset?

[@UnstableStrafe]

For fixing the diagonal movements, I'm curious why you used a float instead of normalising the vector?

[@Dani_Krossing]

Normalize is perfectly fine too, and a simpler solution if you just need equal speed in all directions. 🙂 The main difference is that the way I did it allow for more customization.

[@WarmFuzzlyBear]

The Animator tree was supper hard this was easy to follow

[@scottisitt]

That’s really cool that we can control the animation state with code instead of the blend tree! Thanks for showing us that! Question…if we do it through code, do we still need the animation states to be in Animator (as in 23:48)? EDIT: I'm guessing the answer is yes, since that's the player controller...

[@Dani_Krossing]

You are correct, we do still need them. 🙂

[@scottisitt]

@@Dani_Krossing Thought so :) Thanks, again!

[@atharvalangote8258]

What if we want to keep the character looking in the direction after we stop pressing arrow keys?

[@gralegath]

Another set of sprites and then inside the state machine you'd need another set of states, somthing like PLAYER_IDLE_LEFT/RIGHT And probably another variable that stores your previous movement, just like newstate updates current state, only it dosent update with the new one.

What software are you using when you write your code? It just opens notepad for me.

[@Dani_Krossing]

When you install a Unity version, it prompts a window where you can choose to install Visual Studio as well. This is the editor that most use with Unity. 🙂 However I recommend downloading Visual Studio directly off of Microsoft's website, in order to get the latest version, since Unity prompts you to install the older 2019 version. I have a "how to install Unity" video on my channel, that shows how to set up Visual Studio correctly with Unity. I recommend watching that afterwards.

Hello Elon Musk, thanks for great tutorial.

[@wstkevin4161]

At 21:04 you mean diagonally again right? 😅

[@SirAntonic]

Quick question (I Hope) if i were to have the ending animation frame facing a different direction then default idle (aka an idle animation for left,right,up, and down) how would I go about having the code see that, The code currently if I'm walking and stop walking to the left the character snaps to facing forward instead of staying to the left.

[@Dani_Krossing]

You need to create idle animation sprites for all the directions, and just activate those depending on the direction you last moved

[@gasmaskguy123]

@@Dani_Krossingcould you please tell how do you do that? I know zero C# 🥲 (how to activate them on the direction last moved)

[@corbinbujnowski4016]

I'm a newbie so take my advice with a grain of salt, but what I did was play the walking animation when Input.GetKeyDown then play the idle animation when Input.GetKeyUp. However, the animation is not fluid at all so I'm looking for a better way. What I would suggest doing if you create an animation state dependent on the virtual axis (like in the video), is to play the idle animation when the rigidbody's velocity is 0. I haven't tried this yet so I don't know if it works. I hope this helps a little bit if you still have this problem.

If your character starts running as soon as you start the application, then it’s most likely the input logic that has a typo. If your code looks the same as mine, it should only run if you press a movement key. 🙂

I could explain to you why you get the error, but I don't think it would do you much good in the long run. 😕 Like you mentioned, you haven't learned any C# yet, which means you will struggle a lot with most code you write, because you jumped ahead in your learning a bit too fast. So here is what I recommend you do... Unity require than you know how to code at least a little bit, since coding goes hand in hand with game dev. 🙌 I know "programming" can sound scary if you are new, and I know that you are eager to get started on making a lot of fun games in Unity 🙂 ... but I can't stress enough HOW MUCH you would benefit from learning a bit of C#, before you start making your first game in Unity. I promise that you will be able to learn it fairly easy. 🙂 In this playlist I have here, you will learn how to do all the essentials when it comes to C# programming in Unity.

Isn't Input.GetAxisRaw() using the old input system? Is there a way to modify this code using the new input system? I mean, I'll look online, but just wanted to ask. Edit: Would something like this work… void Update() { Walk(); } void OnMove(InputValue value) { moveInput = value.Get(); } void Walk() { float velocityX = moveInput.x * walkSpeed; float velocityY = moveInput.y * walkSpeed; rb2d.velocity = new Vector2(velocityX, velocityY); } …or something like it? Would the Walk() be called in a FixedUpdate() instead?

[@Dani_Krossing]

The new input system is a package you need to install, which comes with some cool benefits. 🙂 There is nothing wrong with programming the movement like this if you don’t plan on making the movement complex, or cross platform compatible. It is also a complete tutorial in itself to set up, which is why you will see KZbinrs do tutorials without it. Otherwise it would confuse more than what it benefits hehe.

[@Dani_Krossing]

Walk() would need to go into a FixedUpdate() since you are using a rb2d component for movement. I wouldn’t include the rb2d.Velocity inside your update, since it would run even if there is no input or the input hasn’t changed. Which is just going to collect garbage. So I would do an extra check to see if the input has changed since last frame. Other than that, if you plan on using the new input system then you are headed in the right direction. 🙂
