    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.

    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

      I also had this problem but why does this work? How is unity still using the speed value to determine the character's speed even if the line isn't there anymore and speed is not used anymore? I'm very confused.

      @hellsgate700 6 місяців тому

      @@markos_aki At 9:12 he just moves that line of code under the wallJumpCooldown conditional, so speed is still being used. I forgot why I kept that line of code in the same spot as well instead of moving it like he did, but I assume its because I was following along while listening at that moment and didn't see him move that line of code when he did.

  • @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.

    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.

    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.

    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
    :)

    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.

    • @markos_aki
      @markos_aki 6 місяців тому +1

      Not sure this is the best solution, but a more optimized code would be to just
      return body.velocity.y == 0;

      @heypikachu276 6 місяців тому

      @@markos_aki fair enough - I switched it to a system that uses a raycast to the left and to the right. When a player jumps, it checks which direction they're facing and allows them to jump off the edge of any platform while still using IsGrounded()

    is after the if() for jumping [still inside the big if (wallJumpCoolDown > 0.2f) ]

    @fry7746 2 роки тому +3

    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 :)

      To exit the "wall hanging" you will want to make a wall tag and a walled parameter (book) when your player is colliding with a wallas well as a isfalling book. Once walled is false and falling is true you can initiate falling state and from there go to running or idle. Mind you I started unity this week so this may not be an optimal solution but it works fine for me

      Make sure the grounded object has the "Grounded" tag. Also double check if you typed the tag the same way in the code and in the editor, tags can be quite tricky and problematic that's why you need to be careful with them.

    • @PandemoniumGameDev
      @PandemoniumGameDev  3 роки тому +1

      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 don't understand why you moved the "_body.velocity = new Vector2(horizontalInput * _speed, _body.velocity.y);" line at 9:13 from line 24 to line 43 in the if statement for wallJumpCooldown.
    I also don't understand why it doesn't make an error.
    That line of code was meant for the speed of the movements on the horizontal axis, so why did you put it inside an if statement for jumping on walls? And why does it still affect the player movement when walking/running on the horizontal axis even though it's in that if statement?
    In other words, I see that it works, but I don't understand why and it thus doesn't make logical sense for me, which means that it won't help me improve unless I understand why it does what it does.

    • @mikehynz
      @mikehynz 2 роки тому

      I was confused too but I *think* I figured it out. I used a print(wallJumpcooldown) to watch the wallJumpCooldown values in the console window as I played to figure out what was going on.
      The "wallJumpCooldown += Time.deltaTime=;" means that "wallJumpCooldown" initially equals how many seconds have passed since the game has started.
      This means that: "if (wallJumpCooldown > 0.2f)'" becomes TRUE 0.2 second after the game starts, and the update will now run the code *inside* the if statement, thus allowing the player to move fractions of a second after the game starts. wallJumpCooldown only resets to 0 when we hit the wall, thus putting us back outside the if statement, assigning wallJumpCooldown += Time.deltaTime" again. When .2 seconds have passed, we go back inside the if statement allowing the player to move.
      To see this condition in action try changing your code from "IF (wallJumpCooldown > 0.2f)" to "IF (wallJumpCooldown > 5.0f)" . Then save the code and start your game - you will notice that you will not be able to move until 5 seconds have elapsed. When you jump to the wall, you won't be able to move again for another 5 seconds.

    hey uh, i have some issues please help. Sometimes when i jump onto the walls i stick to them, even when i press A or D to go to the opposite direction, i still can't get off the wall. I've tried to fix but i couldn't get it right. :((
