We are taking a look at how we can get our character to react to the slope of the ground he is walking on. This is a good simple way to handle slopes that does not require custom physics.

I LOVE YOU MAN! I switched from regular tiles(without slopes) to an enormous handmade image level system but slopes been a true pain. Now everythings works perfectly

[@P0CK3Y110]

So for anyone who followed the tutorial and did everything he did in the video, but still wouldnt have their characters stick to the slope (especially when walking downwards or up a sharp edge), make sure to change the Ground Check Radius variable until you find a value that fits your needs. Mine was way too small (0.03) and it took me way too long to figure out what I did wrong. Still an absolutely amazing video that shows a concept which is not that easy to grasp when you first read about it. Great work!

[@carlos_7x]

I'm still dealing with this. I had tried with so many values on GroundCheckRadius but still my player is moving down while on a slope... any hints into that? I know it's been 7 months hahaha. I appreciate your comment and thanks in advance! :D

[@P0CK3Y110]

@@carlos_7x Make sure you draw your Ground Check Radius, so you can actually see if your circle overlaps with the ground. If it does overlap, you know it has nothing to do with the size of the cicle. My guess is you messed up somewhere in between. If you did follow the tutorial precisely you should have your character sticking to the slope.

[@billynewcomb2485]

Fixed my Problem!! I was on the right path before this video, but this solved the problem of launching off of the slope and jittering down the slope. I did change the y velocity, when grounded and no slope is detected, to a negative number because it was launching still, but that completely fixed it.

[@Thassio0009]

Thank you so much for this tutorial, you saved my life!

[@Bardent]

You're welcome! :D

[@cystudio5155]

Overall, this system works great, but I had trouble getting it to fall right. If the character was falling next to a fully vertical wall, it would stop moving if you held the directional buttons against the wall. The way I fixed this was by adding the newVelocity to the rigidbody position and multiplying it by the fixed delta time instead of adding it to the velocity.

[@victormeas7898]

There's a big oversight in this video: you never mention a condition where isOnSlope can become false in SlopeCheckVertical(), ergo: you will always be considered to be on a slope after you get so much as a different angle from your initial normal. What should be done is get the angle, and compare it to a threshhold (if its around vector2.up then you're not on a slope)!

[@pedrinkss]

Yep, isOnSlope ends up forever "true" after entering a slope. I managed this issue by checking if (slopeDownAngle != 0), then I set isOnSlope = true. On the else statement, I set isOnSlope = false. This implementation worked for me, for now at least. Cheers!

I wrote a system similar to this in a project before but I'm not sure where it is, so this is a real timesaver! I think the only adjustment I'll make is to apply gravity in the direction of the negative slope normal rather than changing the physics material

Thank you 👍

[@Bardent]

You are welcome :D

[@christucker9566]

The largest issue with this implementation is that you can't benefit from the Physics engines Forces anymore to apply things like Knockback, as you are over-riding the velocity. Instead, you need to calculate the velocity that you want and use forces to keep the player in place. To do this is quite simple.. Vector2 currentVelocity; Vector2 targetVelocity; Vector2 difference = targetVelocity - currentVelocity; Vector2 force = new Vector2(rigidbody.mass * difference.x, rigidbody.mass * difference.y); rigidbody.ApplyForce(force, ForceMode2D.Impulse); This will keep the player in place for the movement, but also allow ApplyForce to work for knockback and other things.

[@genasols.r.l4910]

Good, a question, the player jumps finishing a slope of 45, do you know how to make him not jump?

[@snebbusneb541]

Hey! I know this is a late reply, but where would you put the above code in the player controller script?

[@theDarkerSan]

There's a bug where the walls are treated as slopes and you get stuck. To solve it just check if the "slope" is more than x angle. Like this. if (slopeHitFront) { float slopeFAngle = Vector2.Angle(slopeHitFront.normal, Vector2.up); if (slopeFAngle < 75f) { isOnSlope = true; slopeSideAngle = Vector2.Angle(slopeHitFront.normal, Vector2.up); } } else if (slopeHitBack) { float slopeBackAngle = Vector2.Angle(slopeHitBack.normal, Vector2.up); if(slopeBackAngle < 75f) { isOnSlope = true; slopeSideAngle = Vector2.Angle(slopeHitBack.normal, Vector2.up); } }

[@jno7]

Man thank you so much for pointing this out! I've been trying to fix this bug for hours now ;-;

[@berkcan3475]

this is best video thanks for it :thumbs_up:

[@Emilis2023]

In case anyone else is having trouble with this like I was, after a lot of messing around I realized my problem was I was casting a collider out in front of the character to do a wall check then had a condition set to stop all horizontal motion if one was detected to prevent sticking to walls. If I walked towards a slop the bottom of the collider was hitting the edge of the slope and triggering "onWall" so I couldn't move towards it. Turned that off and it worked just fine. Of course now I'll have to get them to work together, but I think it should be a simple onWall && !onSlope or something similar.

[@David-Obermiller]

I was having the same problem. I had to create seperate layermasks for walls and ground. Not a big deal since I plan on implementing wall slide/jump later and was going to have to do this anyway.

[@mintydog06]

Excellent tutorial. You've covered so much, and I'm very grateful! 26:36 that scared the S**T out of me! lol Can you please explain how the Vector2.Angle is getting the angle. it's using hit.normal, that's the green line ins't it? So it's getting an angle between the green line and a vector that points straight up in the air? When I look at this during gameplay the angle doesn't look 45 degrees to me, it looks to be half that. When I use a much shallower angle, I've got it printing out that the angle is 17 degrees. I have a hard time following what's going on unless I can visualise it. I also have a weird bug where my character can jump even after landing on the slope. It seems at some point the player lands, then slopeangle is set to 0, so then canJump is set to true again for one frame, so the player can then jump while on the slope. I can't work out why. From what I can see, when this happens, the red ray points to the left, instead of along the slope

[@kremmidis_773]

the Raycast doesn't hit for some reason and the Gizmo never shows up, doesn't work for me

[@Atomic-Potato]

Its a pretty good script for slopes, one problem tho, when you land on a slope while holding the a or d buttons the player will slide down the slope even if the slope is under the max slope angle, any idea how to fix this ? UPDATE: i managed to fix it with the help of bardent discord, turns out isJumping doesnt turn to false when i do that because the velocity.y will never become zero which means the conditions are not true for it to switch isJumping back to false. SOLUTION: in the CheckIfCanJump(); add if(isOnSlope) { canJump = true; isJumping = false; } simple fix but took a while to figure out whats wrong

[@gelis07]

Hey Bardent! Really enjoying your videos and learning to program in the procces. I have a bit a of problem applying this to a 3d game.

Any workarouds for this? thanks in advance!

[@chickendilla]

Forgot to mention that its a 2.5d game where yo cant go in the z axis.

[@Bardent]

hmmmm... I can see why that function would not work but I am not too sure about a workaround. I can help think though if you wanna message me on discord and we can discuss it :)

[@CarloMercadoJudgementProject]

hi, thank you, really nice tutorial, and method for the slope, I have a question, how can I ignore the slope detection when the player is colliding with a jumpthrough object that is using the plaftorm effector 2D. my idea is to put that objects in another layer, but the problem is that the event for isGrounded wont be trigger with that objects, so the player wont be able to jump.

[@Bardent]

Hey! Thank you! Hmm I have never used an effector 2D but I assume if you put the effector on another layer and then add that to the whatIsGround layermask, then where you detect slopes.. once you get a hit you check if the layer is Ground or Effector, if it is effector you ignore it and if it is ground you do the slope check :D

[@chrislaguna8390]

I ran into the same issue, its actually a problem with the isGrounded logic, not with the slope detection stuff. What *seems* to be working for me is to first do a raycast check UP instead of down from the same checkPos. if you find something, it would be a fallthrough object. If you are in a fallthrough object, when you check for ground by raycasting downwards, don't check for jumpthrough objects. For me I distinguished jumpthrough objects from normal ground with the z dimension. Hope that makes sense!

[@clydemarindo3177]

where do i cast the ray if i use a box collider instead of a capsule collider?

[@madrustrel]

I have the same problem, and I am wondering if I should change all my animations to fit a capsule collider, or if there is an easy way to apply slope movements to a box collider (to me, they seem to be very similar things, but unity doesn't seem to agree)...

With HingeJoint2D acting as a wheel moving your character you may get some nice results without so much coding :)

[@brunosouza9809]

Can you explain how did you do it?

[@GameDevMarek]

@@brunosouza9809 Your character has a wheel (Circle Collider) rotating with motor speed value of hinge joint. It's similar to setting up a 2D car with two wheel joints. Hinge Joint is connected to player main rigidbody with a bit wider collider than wheel radius, so it wont try to ride on walls.

[@brunosouza9809]

@@GameDevMarek Ok, thank you, I'll try it.

[@gunbuckybucketman4578]

So the Horizon check is just casting ray to the Front and Back of the character and check onSlope to true? But what did slopeSideAngle do?

[@Bardent]

Hey! So I had to go back through my code to quickly figure this out but the slopeSideAngle part makes it so that... when we run into a slope that is too steep for us, without the slopeSideAngle, the player would walk up it a little bit then start sliding down, but he will only slide down till the ray shooting down detects a normal slope again which would turn on friction. So he would now slide down all the way. So this is the part where we set canWalkOnSlope to false if slopeSideAngle is greater than maxAngle. Hope that helps clear things up :)

[@gunbuckybucketman4578]

@@Bardent Oh, Thank you

[@gunbuckybucketman4578]

@@Bardent Okay, this is what I'm understand. The SlopeCheckHorizontal is only for detect slope for onSlope check and nothing else? No movement stuff in the method right? *edit : Now I get it, because isOnSlope is true, it will force the player to stick on the ground with "rb.velocity.y" in ApplyMovement method. Thank you again, I'm really into this kind of stuff.

[@youtuberyoutuber2495]

Will this whole script still work if our character moves automatically to the left or right (you dont press any key, he moves by itself)?

[@Bardent]

Hey! Yes it should still work as long as the character uses the same movement code. So in ApplyMovement I think, instead of multiplying with input direction you can use something else that decides if the character should be moving right or left :)

[@mini7279]

This video was great! the script worked very well, however, the character bounces when going down steeper slopes (e.g., 50 degrees), it also occurs at a lesser degree when going down shallower slopes. I tried looking up tutorials on how to stop this, however I've had no luck with any of them. I directly copied and pasted the source code to ensure I did nothing wrong but it still occurs. I was wondering if you know a solution to this?

[@bannedaccount586]

i know this is old im leaving this for anyone who may have this same issue the bounciness issue can be cause by the sprites physics shape if youre using a tilemap with a tilemap collider alot of "slope" tiles end up by default with a triangle shape with square edges on the top corner of the shape which causes "divots" to appear in the tilemap collider on your slopes which makes the system think the player is occasionally on flat ground while running on a slope

[@JohnAndrews_nz]

For me, this gets stuck to edges of drops when the "slope" becomes around 90 degrees. its a cliff edge, but it will just stick my player.

[@stasyandr563]

have you found the solution? I have the same problem

[@raphaelstiep9815]

@@stasyandr563 Again this is a very late answer. I had the same Problem, and I don't know if this is a very efficient solution. I made a bool isAtWall and checked for it with a maxWallAngle copared only to the RayCastHit Left and Right Angles. I then added an additional if statement in my Movement Function saying that if I am on a slope, which i can't walk on, but im standing at a wall just add my normal xSpeed and on the y keep the rb velocity. If you need more detail pls contact me

[@Ironlionm4n]

I think I have solved this by add the following code in the verticalSlopeCheck after the check if (slopeDownAngle != slopeDownAngleOld) code - if(slopeDownAngle == 0 && slopeSideAngle == 90) { isOnSlope = false; }

If I comment out everything in SlopeCheckHorizontal, the player does leave the ground for a moment, but not much, and keeps going at just about the right angle. If I put that code back in, the player just flies clean over sharp corners and doesn't change velocity to go towards the opposite slope at all.

there are 2 problems with this code. 1) You stick to walls if you press up against them. 2) there is a pause coming on and off slopes.

[@Bardent]

Hey! Okay so for 1 that is my bad I totally didn't even consider straight walls XD But you can fix that by using a shorted slope check distance for the horizontal rays. I used 0.2 and that made it so I am no longer stuck. You will need to live the vertical one as is tho. As for 2 it does not seem to be happening on my side but I do remember something like that happening during development. Can't remember what I did to fix it though as it's been a while. If I remember i'll let you know.

[@matheusreidopedaco]

Can this work with AddForce? How?

[@stellarestuary589]

I was close to getting something working but there are a few things happening with my game: 1. The character is still sliding down the slope. Furthermore the 2D Raycast is not shoing up for my character. 2. While the character does still slide, however, the code I used from your video managed to fix an issue where the jump animation when facing walls would continue to play upon landing back on the ground. So the thing about my code is that it uses a script that I wrote that is actually a 2D Player Controller from Lost Relic Games's Mega-man style tutorial video, so I've expected something like this to happen. I've tried adding a physics material to the slope as well to stop the player from sliding with no luck. Am I missing information that I should look into before following your video? I actually don't understand some of the logic here, so I'm thinking of putting this problem on hold for now.

Hey! whatIsGround refers to a layermask that we use with the raycast so it only detects objects on the same layer. So basically our ground is on a Ground layer and the physics check only checks that layer.

Ah okay thx

Hi this works really good, but if my slope gets too steep (an angle higher than for eg 50), the "maxSlopeAngle" doesn't matter anymore, the character starts sliding up. Anyone else has the same issue? btw this only happens when the slope is tilted right (positive value) EDIT: I found the my issue for anyone with similar problems. My "isGrounded" was set up differently than his. I increased my grounded radius and it fixed the problem. If it doesn't work try to increase the Slope Check Distance too.

Thanks for sharing your fix!

how to make loops de loops like in sonic

oof I'm gonna need a while before I can figure that one out

I wanna make mobile control joustick linked to the character

[@hiiambarney4489]

hmm sadly, nothing of this works for me at all. Messed up my entire code and wasted 30 minutes of dev time for my jam. So this is my perspective, could be I'm doing something wrong but I was trying to modify the character controller from Bardents other series, not sure why he didn't use that as I am very sure it's a high% use case for regulars on his channel.

Hey I'm sorry this did not work for you. Slopes with built in physics is definitely a little finicky and take a lot of testing and tweaking of values to get it to work right. That is the reason why I am not yet including this in my main project as I would rather spend that time working on other features. Hope you managed to get everything working for your jam though. Good luck!

@@Bardent It's ok man. I spent a day rewriting an entire raycast based platformer physics system before I noticed my tilemap collider put whacky dents in my obviously flat surface sprites for no reason. An apology is due. Sorry man! It can be frustrating sometimes working with Unity 2d

hi im from Your followers on youtube, can you help me , i have problem. about How to create mobile games for different screen sizes and resolutions. im wait your answer, thank you so much

[@Bardent]

Hey! Unfortunately my experience with that is very limited but I can recommend a video called "Handling different aspect ratios in your Unity 2D games" I hope that has what you are looking for :D

There's some definite issues I'm having with this. Even in your own project, the player gets consistently stuck whenever it goes against a totally upright wall, only being able to free itself by jumping

[@JackBz]

this is if the wall is totally upright and floor is totally flat

[@danmorin5894]

I ran into this same issue. I resolved it by adding 'if (Vector2.Angle(slopeHitFront.normal, Vector2.up) < wallAngle)' around the two places where slopeSideAngle and isOnSlope are set in the Horizontal Slope Check. wallAngle is some float that describes a slope so steep it is a wall. I used 87

i have the same problem... Did you figure it out??

[@Bardent]

Hey! In the game view make sure you click on the Gizmos button at the top right of the window to toggle it on and off. This can be done in the scene view also :)

Hey I have the same problem, you may have the same disorder I have called Misophonia. Many people suffer with this disorder without knowing it exists.
