[@RickydeCamargo]

Hey man, thanks for this series of unity 2d videos. They are very helpful to us beginners. I have a question: In order to have a better and clean coding do you recommend to us to build only a gigantec script with every new hability ? Or is less complicated to create a script for every new skill ? I mean, a script just for walk, another one just for jump, etc etc. And we can manage easily on unity ? Thank you.

[@TheStinkyFrog]

I'm still learning myself but I thought I could give my answer to your question. I use unity and when I create a script for my player's movement, I usually call it playerMovement and put all player movement inside that script. That includes basic movements using WASD and any jumping for the game. I haven't made a game yet with special abilities for the player but depending on the ability, you could put it in playerMovement or into another script. Something like double jump or dash, I'd probably put into my playerMovement script though. It isn't hard to manage as long as your code is clean and your variable names are easy to understand. I hope that helps if you haven't already come to a solution/answer 😊

hi bro i love your stuff , they are masterpiece but can you make a video about adding acceleration and decceleration for smoother 2d movement?

[@bendux]

Try Input.GetAxis instead of Input.GetAxisRaw.

[@meltedistaken]

Hey, I was wondering if you could make a tutorial on how to make movement with acceleration. My movement feels very stiff and I want to have it to where if I start holding "D," it takes some time to reach maximum speed. Or when I turn around and instantly start moving the other direction, I want it to take some time.

Try Input.GetAxis instead of Input.GetAxisRaw.

[@user-ww7wm2qr1k]

I love you so much, I’m from Yemen

[@cj.shot8616]

thank you SOoooooooo much, How can I increase my character wall jump ?

[@tylerhuff7394]

This code works great for vertical jumping up walls, but it doesn't seem to be pushing the player off the wall properly. If I have the player sliding down the right hand side of a wall and press jump without holding down a movement direction then they will occasionally get a small bit of movement before resetting their Rigidbody velocity.x back to 0. In this video are you actively pressing in the direction opposite the wall when you jump off? I think the problem is tied to update refreshing the velocity based on horizontal.

[@bendux]

Would you like to show me your code on Discord?

[@SalikShorov]

Thank you for the video. For some reason my player starts to slide up when it’s on the top half of the wall and slides down when it’s on the bottom half. I don’t if anyone else is having the same issue.

[@bendux]

Would you like to show me your code on Discord?

[@meltedistaken]

Hey, I was wondering how I could use acceleration and momentum with the wall jump, as it feels stiff. As soon as the wall jump ends, I can start moving the other direction without speeding up.

[@bendux]

Try Input.GetAxis instead of Input.GetAxisRaw.

[@jevonbulze1429]

Im using this code along with the dash one but I'm running into an issue where my dash doesn't work. Any suggestions?

[@zynnonP]

Could you maybe make a tutorial on a top down dash? I've seen your platformer dasv but i can't seem to implement in vertically, could you maybe help me with that please?

[@Coleslaw333]

You could use a bool and increase the move spped for a short amount of time like 0.2 seconds with an Enumerator like If(whatever key you want pressed & & candash) { StartCoroutine(Dash() ) ; Candash = false; } IEnumerator Dash() { Move speed = whatever. Make it high enough; Yield return new WaitForSeconds(0.25f); Movespeed = whatever it was before; Yield return new WaitForSeconds(however long) ; candash = true; }

[@bendux]

Would you like to show me your code on Discord?

[@lazougre4229]

your player could by rotated to the wrong direction from the beginning. you can flip it in unity by adjusting the scale on the X or do the same in the start method: void Start() { Vector3 theScale = transform.localScale; theScale.x *= -1; transform.localScale = theScale; } (Doing it in unity is better :) )

the problem with assigning the "wall" layer to the walls is that they will not count as ground if you stand on top of them and therefore you wont count as grounded when on top of a wall. this is no good if the wall is also part of the same object that is a floor.

[@bendux]

I've added it to my list. Thank you for the suggestion!

[@Natycik]

Tried your method, but it's not working because of colliders. Basicly, if the player is aganst a wall and "runs" into it, the player stops moving and doesn't fall (y velosity is 0). Your player object seems to not collide with objects in that way, I'm not sure what you did to prevent this.

[@bendux]

Create a Physics Material 2D, set the friction to zero, and add it to your player's Rigidbody 2D component.
