I think i never subscribed after just one video. But halfway through the video you convinced me. 10/10.

[@vonvetur]

I had some issues with jumping so I started to look at random jumping tutorials, and basically all I needed was to reset the y velocity to 0 on jump. Thank you for that.

[@n1k000z]

yea but can anyone tell me why did he do that i mean we never applied any kind of y velocity before did we?

[@donglesband]

@@n1k000z It's so you always get the same velocity no matter how fast you spam the jump button. It can cause inaccurate physics predictions like the jump being executed twice, making you jump extra high sometimes.

[@konarkpahuja5047]

these tutorials are a godsend. did you/he ever make the wall jump tutorial?

[@Matdif]

When you add drag to a rigid body this effects both dimensions in Unity2D. As in rb.drag is altering our jump height. If you stay still (x direction) while jumping your jump is dampened. When you are moving while jumping it is not so the jump is higher. I changed the application of rb.drag to call a method instead. private void ApplyHorizontalDrag() { rb.velocity = new Vector2(rb.velocity.x * Mathf.Clamp01(1 - dragConstant), rb.velocity.y); } This applies the drag only in the x direction leaving the jump unchanged. I replaced the rb.drag = linearDrag with a call for this method in fixed update. The else part of the statement is not needed since this is applied each time and does not change the drag and therefore does not need to be changed back. I used dragConstant = .9f so far but lowering it gives you a softer stop when turning and such.

[@TheNjyon]

This kind of ground detection works fine for fast and easy prototypes. The problem with this one is obviously when u stand on an edge u will be in the falling state without falling. Sure u can add 2 more RayCasts to be safe for the most parts but if you want it 100% accurate u should sweep ur component. Unity provides u with a Box, Speher, Capsul ... Casts. That should work great for "most" cases

[@BobrLovr]

lol, or you can literally just add two more raycasts, one for each edge of your player. It's not that hard

[@studioprimitive]

This helped greatly with my character's jump. Thanks!

[@DecrareOld]

I subscribed to you today. you can explain everyrhing i need really good

[@VEOdev]

For the ground check it is better to use a sphere cast and not a line cast Also for the short jump you can just put Y velocity to 0 when you release the jump button so the character will fall down as soon as you let the key

[@ggiillii2813]

Help My falling animation only plays when I hold the down key or "S" and only stops when I press the up key or "W".

[@WakeTheShark446]

Great video! One issue I've encountered however is that on impact to the ground, the character dips into the ground ever so slightly before popping back out and interrupts the player's velocity. I'm currently using a box collider for my character but also tried an edge collider like how you have it on yours to an even worse effect. Is there a fix to this?

[@andrew_ceco]

Hey friend, I'm probably too late to be totally helpful HOWEVER... I've found that the player is going to dip into the ground no matter what, but going to your RigidBody 2d settings and changing your Collision Detection to continuous should help with it to some degree

[@pagoda_dimensionale9761]

same, have you discover the problem?

[@private3946]

Set your Collission Detection to Continuous or try setting interpolate on extrapolate/interpolate in your Rigidbody2D settings

[@SageNode]

the Jump Delay you put in, is that basically coyote time?

[@cools7uff]

How do I fix the hang time before the character falls after holding space

[@karacter3369]

for some reason the character slows down when hitting the floor, almost stopping, i wanted it to keep it's previous velocity...

[@danielgarcia-je9lc]

Great job!

[@hatoving]

The jumping works fine for me, but when the player reaches the ground, the gravity scale snaps from 5 to 0 quicky, where it stops the player for a millisecond and then walks normally. Any fix to this?

[@victorlecam1813]

Same problem here. Someone ?

[@uba754]

Same problem too, went back to double check everything and seems identical.

[@McCooler]

I've solved this adding a material with no friction to my player collider... don't know if this is the correct aproach

[@seighart90]

one thing i notice that using this code, if you have a running start you'll jump much higher than from a standing start because the force is stacked. This could be a cool feature if that's what you intended

[@uba754]

My code and scene is identical but my character very briefly pauses when they hit the ground after a jump. Any idea why? Would love to fix this. Fantastic tutorial though really!

[@SageNode]

would also like a solution for this

[@uba754]

@@SageNode Many of us in the comments have been using a physics material 2d to kind of fix this. I don't think it is perfect but its the best solution so far. Add the material to the ground plane with friction set to 0.01 and bounciness at 0. Have also read something similar but with the material on the player but I haven't tested it yet.

[@SageNode]

@@uba754 works like a charm. thanks

[@marksimpson4310]

Great tutorials. I would love to know when you'll release a wall jump tutorial.

[@Charles-Darwin]

Couldn't you do another raycast horizontally and have it interact with a wall layer.

[@Prox_C]

@@Charles-Darwin Pretty much this. Halt velocity and have a bool for IsWallJumping. limits inputs to what you want while latched on and set a new animation frame to show collision with wall surface. add impulse at an angle something like 60deg away from wall when jump is pressed and you're done. fixed wall hold vs sliding down would be design choices but the slide down wall can be achieved with a low gravity multiplier. Finish up by wrapping the input in a countdown that drops the character if no 'jump' input is made in time, resulting in the character letting go of the wall. Hope this helps anyone who comes across it.

[@Charlie59876]

Does anyone know why my player slows down when i jump?

[@TheWgaffa]

Not sure what I'm missing but when my character lands it gets "stuck" for a short moment when landing. But your character seems to go at the same speed after landing.

[@kamiieel]

i have the same problem i dont know what makes it do that

[@bambonats2250]

You could try setting the "Collision Detection" of your character's Rigidbody2D (I assume you are also making a 2D game) to Continuous. This stopped that weird "sinking in" thing when you land. Hope this works out for you too

[@TheWgaffa]

Thanks, I got it to work and it indeed seemed to be Collision Detection needed to be set to Continuous

[@smokinglife8980]

Also if you don’t want to be limited to certain layers to walk on just don’t use a layermask or have a layermask helper script that gets all the lays except what you specify

[@mouradeid5457]

So I copied the script, I noticed that when I move horizontally then jump the character jumps higher than when it jumps while standing still, I tried several methods like clamping y velocity, using a targeted height and stop and it and others, none of them gave me that elegant result, any idea how can I fix this?

[@efn5520]

Someone said If(rb.velocity.x > 5) { Whatever you want } But I don't know if it works because i don't know what to write in Whatever I want

[@Yamam100]

great tutorials

[@SageNode]

a problem with your set up is that vertical is only detected to activate the falling animation when you press down the S key. but why would the player be holding down the S key just so we can see the animation play. The fall animation should play when you are falling without having to hold down the S key.

[@ΔΑΝΙΑΝΟΣΑΠΑΤΑΓΓΕΛΟΣ]

I have a problem when i jump left or right, i get drag/magnetized to the closest wall how i can fix this?

[@chaseums0967]

"This next part might be a little overwhelming, so I'll explain it slowly." *proceeds to blast through the entire rest of the video* Regardless, very informative and you do explain what you're doing. Maybe just too much all at once for my brain to handle, LOL. It's a me-problem.

[@林厚廷]

I have a question, set the collision detection to continuous is a good way or not, I know that this setting may use more resources.

[@jacksonisaac9686]

What about for 3d?

[@fettigerburger9258]

When I just run my player stops moving randomly, and I have to move in the other direction to move again

[@andrew_ceco]

Hey, I'm probably waaaay late for this, but you're getting stuck on tile colliders. The best solution for me was: 1. Create a new Physics Material with Friction set to zero 2. Attach to the Edge Collider 2D If this STILL isn't working, then: 3. Go to your RigidBody 2D settings 4. Change Collision Detection to Continuous As a note, other people have suggested adding a Composite Collider to your tilemap / ground layer, but that solution didn't work for me for some reason haha Hopefully all this info helps you, or some stranger in the future :)

[@nightstech7499]

OMG you are a life saver thanks alot :)

[@СергейКоваленко-п2я]

I want to see as a following to this useful video how you cope with the issue of the slope when the player slides down when staying at the slope and when the player is jumping at the slope when going up and down. This is a very common problem I think, but it`s hard to find good information about it.

[@ruijiang6274]

Is there any difference between using two Raycast and using a single Boxcast?

Hello everyone ! does anyone knows why my character loses X velocity when landing ? Except from this problem, it all works pretty good. Thank you for the videos !

Having the exact same problem I think. As soon as the character lands after a jump they pause for a brief second before continuing to move.

[@torbrandt5546]

[@BoltGoesPro]

Hey I have a question, so when you hold left or right, it makes you go higher when you jump, why is that? Edit: I figured out why, Am looking for a fix, it's because when you are holding down another button along with jump it acts like it cancels it out?

[@vstechvideos9373]

Just a quick doubt, why not use an Empty GameObject with a box collider2D at the bottom of the character to check if the character isGrounded? Raycasting is Wayyy Complicated.

[@BobrLovr]

hows it complicated? Unity literally did it all for you, you just have to implement the function

[@TackleProd]

There is a bug in the code... When standing still, the Linear drag is applied. So when I jump, I cant really jump that high. (The drag changes to 0 when already in the air, but then its too late) However, when running, the drag is 0, and I can jump really high... I dont know how to fix this yet, Ive tried a lot of things...

[@memoal-said5111]

I got the same problem but I found out the source of the problem. It's the linear drag, that part of the code that's supposed to prevent the player from sliding when it changes directions. Sadly, I don't know the solution but at least the source of the problem was found.

[@TackleProd]

@@memoal-said5111 Toshi 1 second ago Actually I found a better solution that doesnt mess with drag at all, but still gives that smooth movement. void MoveCharacter(float dir) //Dir is the control stick's input. 1 for right, -1 for left and all that. { Vector2 targetVelocity = new Vector2(dir * stats.maxSpeed, rb.velocity.y); //I have my maxSpeed in another script, but whatever. // And then smoothing it out and applying it to the character rb.velocity = Vector3.SmoothDamp(rb.velocity, targetVelocity, ref stats.m_Velocity, stats.m_MovementSmoothing); //SMOOTH DAMP is the key! My Stats movement smoothing is set to 0.05f. Works both when accelerating and stopping. }

[@memoal-said5111]

Believe it or not. I actually solved this long ago but forgot about this post. My solution was just to use a boolean to check when the player jumps or not and it works. Without that boolean, the issue occurs and I'm surprised that fixed it. XD

[@MariWeiss28]

thanks, come back man pls.

[@tylermaxwell7599]

As soon as I added jumping i started sliding on the ground again after moving instead of coming to a halt like in the last tutorial

[@juanchoavid123]

Hey, Excellent video, if you still answering, i normally use circle or sphere overlapping for detecting ground, I have seen people, like your case that use raycasting, is there any difference? like performance difference? or it doesn't matter in this case?

[@YehielCertner]

Hi, Great tutorial and a great channel! I implemented the jump and it works great, i want to implement a Platform Effector to some of my platform tiles but theres a problem since the raycast is touching the platform from below when jumping and it thinks the player touched the ground so it would go all up the platform in some heights, tried shortening the raycast but it doesn't work , any suggestions will be very helpful :)

Yehiel Certner if you can't change the length it's because (probably) you multiplied (in your script) by ground layer and not ground length . If you didn't make this mistake then just try checking the video again

[@lucas90gs]

My character loses x velocity when he hits the ground after a jump. This feels like he is dragging a bit after every jump. What can be causing it? Did you change the physics material of your tiles?

[@dylanfoster186]

[@memoal-said5111]

I actually had the same issue as you did. My solution was to use a new boolean called "jumped" and set it to false. I added that boolean to the code that handles linear drag to stop the character from sliding. It's this piece of code you should have in your script if you followed the video fully. Void modifyPhysics() { ... If(Mathf.abs(direction.x) < 0.4 || changingDirection) ... Change the if statement to this instead: If ((Mathf.Abs(direction.x) < 0.4f || changingDirection) && !jumped) The jumped boolean turns true whenever the player pressed down the key that makes the character jump and the book turns first if the player touches the ground again. Also, add the bool inside your key press code that has the function Jump() BEFORE it so it works. I hope it works for you like it has for me.

[@rodrigofierro2212]

Guys, I need help. The part where the player has high jump and low jump isn't working. My code is the same as in the tutorial, but for some reason, when I press "jump" it only goes so high, no matter if I hold or just tap the button.

The linear drag is 0 when running, and 4 when standing still. When jumping, the height of the jump is affected by the values I mentioned. I don't know how to fix this problem. When standing still, I cant jump that high. only when running, I get max jumping potential. Anyone else getting this problem and know how to fix it?

Regular ray cast are not good for ground detection and stuff. 1. Walk to the very edge of a block or something you will not be grounded and there is one more problem I just forgot. I would you a sphere cast and box cast it’s will cover more thank just a single line so ground checks are more accurate imo
