Just launched episode 4: kzbin.info/www/bejne/hobTdGdqhptnsLs FAQ: 1. I don't recommend skipping this episode, there's some code here that we are going to use later on. If you don't want wall climbing just don't mark any objects with the Wall layer.

One of the better tutorials on KZbin! While other youtubers just type code and expect you to already understand what it does, Pandemonium actually explains in detail each and every line of code!

[@thenacho6354]

even though I don't plan on adding wall jumping to my game, this is still, by far the best player movement tutorial I've seen!

[@astronautboi8431]

I swear this is literally the only thing i've needed so far, i've tried tutorials in the past, however i found they never worked, or were very unoptimized. This tutorial is god tier.

[@hellsgate700]

If your player is only moving up the wall instead of jumping off of it, remove this line in your update function: body.velocity = new Vector2(horizontalInput * speed, body.velocity.y); At 0:10 it's line 19 in the video

[@aapin3348]

Bro I wish I saw this before I removed my wallJumpCooldown. I thought that was the issue so now wall jumping works when you press space on a wall but there is no cooldown lol

[@tommyholmberg8961]

well, hats off and thank you!

[@arunadisesh1715]

Thank you this fixed it for me.

[@soularpowergaming]

Great video. I had an issue where my player was flying and posted a comment here, but editing it to say that I somehow missed that the isGrounded should get the `collider` property and check for null, not the raycastHit itself.

[@naejimba]

This is a great tutorial! I made it all the way so far, and I'm even at the point where I'm changing some things to see what I like (a good way to tell if you understand).

[@tonyaldrich1564]

I'm really glad I kept a backup of my code before starting this. I don't want wall jumping, but figured "I'll follow this for the new jump method, and just get rid of the wall jumping later". The only thing I managed to do was make my jumping worse and break the animation. I even downloaded his code file and copied it into my game. Same thing. I don't know how I messed it up. I know I did a few things differently cause I knew easier ways from other tutorials (like just using "public" instead of "serialized field") The only thing I actually need is a way to stop sticking to walls (I was sticking to walls by just moving sideways and colliding with them in midair) before doing this tutorial.

[@majinjamie971]

Just finished this one, such well made videos!

[@ashwinwilly9746]

Great tutorial really helped me! Keep up the good work

[@jjkilpi]

Now I found Tube's best tutorial. In the first episode, the texts that really came in handy. There has been insane work in them. Pandemoniun has given his all to the free side. All the other professionals at Tube have deliberately made mistakes that are capable of selling a $ 1,000 package, that is a robbery. I have been trying for seven months to get one tutorial to the finish. I've always been stuck. I got stuck in this tutorial 3 because I got some problem with [serializ ...]. I copied the code that Pandemonium had shared with us and got to continue again. This will be the first tutorial I will complete and I will give the Pandemonium an award. Thank you for a very good job. I wish there were more like you.

[@heypikachu276]

Solution for people who don't want wall jumping: For anybody having issues with buggy wall jumping: The character's hitbox sometimes gets confused I think and you can wall jump just by touching a surface. The easiest way to fix this is to change the "isGrounded" function from checking using raycasting to checking using Y velocity. Inside the isGrounded function, replace all the code with this: if (body.velocity.y == 0) return true; else return false; That allows the player to ONLY jump when they aren't falling.

[@jezozwierz7608]

[@ratala321]

I was also wondering why the wall jump isn't working if the statement : body.velocity = new Vector2 (horizontalInput*speed, body.velocity.y); is after the if() for jumping [still inside the big if (wallJumpCoolDown > 0.2f) ] The changes happen around 11:20. Thank you again for the tutorial, I'm glad to be able to learn with you !!

[@DarkLynxDEV]

For anyone that doesn't want to have to change the gravity scale in both the code and the editor when the player leaves the wall. - Create a float variable called initialGravity (or anything you like) - In the awake, set initialGravity = body.gravityScale - Set the gravity in the else statement, when you de-attach from the wall, to the variable initialGravity :)

[@turtlegod1013]

In the first episode, the edit text suggested I make a jump variable to decide how high the character jumps. Is that preferable to changing the gravity scale?

Are you gonna make a video on how to add a little cooldown thingy to wall jump and normal jump since it feels kinda weird like this when its spammable. Really appreciate t if you do keep up the good work.

[@gameprogramming6550]

nice tutorial !

[@rage8673]

idk why but i didn't need the separate else statement code in 10:05 for releasing back to the ground, my character was not levitating without it and was indeed falling to ground, yet i still added it so that it dosen't cause any random problem further in tutorial, do you think my case is normal?

[@BloodCatters]

There is something that I did not understand. Why are we using the raycast method instead of the box collider? They seem to do the same thing. What is the advantage of one on another? It seems that we can do the double jump without using raycast. Thanks in advance for your answers.

[@copykey]

Thanks for the such detailed tutorial. and I have some questions : What transform.localScale in Jump() actually works? I understand that this code makes player flip when it jumped off the wall(to see opposite direction). But it wasn't. Maybe I misunderstood something...

[@ratala321]

Hello! I don't understand why the player can't moove if the statement : body.velocity = new Vector2 (horizontalInput*speed, body.velocity.y); isn't in the statement : if (walljumpCoolDown > 0.2f). The code was typed at 09:15. Thank you for the great tutorial!

[@hellsgate700]

If your player's jump animation stops working, I fixed mine by going into the animator's transition from Jump to Idle and enabling has exit time. Also set the transition duration to 0.

Hi! First of all, thanks for the tutorial! I appreciate it! Its really helpful! ^^ Secondly, ive got my code working, but when i grab a wall on the left side, and i want to jump to the right, it feels very glitchy, and its really hard to make it work. Any idea, how i can improve on that?

[@Gijs9114]

Im not sure whether this bug should be in ''my game'' at this point during this tutorial, but my character can make some sweet front- and backflips when jumping around menacingly.

[@Gijs9114]

but i seemed to have fixed it by adding Freeze rotation constraint on the Rigidbody of the player

Hi, do you know why my character lost his jumping animation when I did the part with the sticking to walls, I am so confused, the issue is in code I guess, here s the code: using UnityEngine; public class PlayerMovement : MonoBehaviour { [SerializeField] private float speed; [SerializeField] private LayerMask groundLayer; [SerializeField] private LayerMask wallLayer; private Rigidbody2D body; private Animator anim; private BoxCollider2D boxCollider; private float wallJumpCooldown; private void Awake() { // referencie pre rigidbody a animator aka animaciu body = GetComponent(); anim = GetComponent(); boxCollider = GetComponent(); } private void Update() { float horizontalInput = Input.GetAxis("Horizontal"); body.velocity = new Vector2(horizontalInput * speed, body.velocity.y); // otoci nam to hraca if (horizontalInput > 0.01f) transform.localScale = new Vector3(2, 2, 1); else if (horizontalInput < -0.01f) transform.localScale = new Vector3(-2, 2, 1); if (Input.GetKey(KeyCode.Space)) body.velocity = new Vector2(body.velocity.x, speed); // jump shit ... if (Input.GetKey(KeyCode.Space) && isGrounded()) // ...

@Pandemonium, how do I fix this error: The modifier "private" is not valid for this item

[@rajatmusale1948]

Hey, follow-up query: even at the end of the tutorial my character stays stuck to the wall unless I specifically hit SPACE or use the arrow keys/A/D keys. It doesn't fall down on its own when on the wall. Do you think it could be an animation issue? I even copied your code to a new file and tested it out to see if it was a coding error on my side.

[@PandemoniumGameDev]

That's how it's supposed to work. Were you expecting it to slide down?

[@rajatmusale1948]

@@PandemoniumGameDev Yes, I was. I mean, we did put in gravity as a parameter to the rigidbody, so I thought it might slide down automatically once it hits the wall.

[@PandemoniumGameDev]

@@rajatmusale1948 Nope, the gravity applies to the time when you are not on the wall. For the wall scenario we wrote body.gravityScale = 0; try changing the 0 value to something else and you should get the sliding to work.

[@YuriRVG]

My player jumps at different height, sometimes flying away from a screen; I tried add vector to vertical velocity, change force methods, change GetKey for GetKeyDown. With some of them it feels better sometimes but then he again jump to the space;

What does the wallJumpCooldown do exactly? I'm having a hard time visualizing it. Mostly the part of the code that says "if (wallJumpCooldown > 0.2f)" and the other part that says "wallJumpCooldown += Time.deltaTime;"

[@PandemoniumGameDev]

It's a timer that prevents you to do wall jumps infinitely so we check if 0.2 seconds have passed since the last wall jump before allowing the player to do another one. If we don't use this you would be able to just fly up the wall, try replacing 0.2f with 0 and you'll see.

I see that it's been initalized in that class's field but it it not declared anywhere in the code with an explicit value. So, how is does wallJumpCooldown > 0.2f true when we don't even assign a value to wallJumpCooldown?

@@overlydedicated2794 wallJumpCooldown starts of at a value o 0 when you start the game. Then we increase it during every frame by using this line: wallJumpCooldown += Time.deltaTime; So basically wallJumpCooldown is a timer. Now every time you perform a wall jump wallJumpCooldown becomes 0, and we use wallJumpCooldown > 0.2f to make sure that 0.2 seconds have passed before we allow the player to perform another wall jump. Does this help?

@@PandemoniumGameDev @Pandemonium Ok. Now I understand. I didn't know it started with a default value of 0. Thank you for the explanation. 😁

Hey man just a question, at 8:40 when the console is showing the true or false detection, my console is spamming true or false for each millisecond and i have 999+ console alerts within a second of pressing play, what would be causing mine to spam like that and how could i go about solving it? Cheers

press the collapse button (also the detection is just for testing you can delete it)

10:35 My player is sticking to the wall even when I press the right arrow which should make it stop sticking. I think that it's related to the collision detection, since I had to use a capsule collider and the collision detection isn't working perfectly. (I have to use a capsule collider since my player was sticking to the ground)

A bit late but I set the edge radius of the box colliders(on my walls, not the character) to a very small number like 0.025 and it seems to solve the issue. Dont know if adding edge radius to character solves the problem. Also for anyone who needs it. If your character start spinning while moving you can tick "lock rotation, z" option under rigidbody/constraints for the character

At 9:14 he cuts the line " body.velocity = new Vector2(horizontalInput * speed, body.velocity.y); " from the start of the update method to enclosed within an if statement. I had that line twice since I didn't notice it was cut and it prevents the clean push off the wall from happening when climbing. Putting this here for any future people who also get confused :)

Please tell me, what is WallJumpCooldown float used for?? I don't understand..

[@PandemoniumGameDev]

It's basically a timer that doesn't allow the player to wall jump immediately. So if you do one wall jump you need to wait 0.2 seconds before being able to do the second one. WallJumpCooldown is the timer that keeps track of how much time has passed since the last wall jump.
