If you run into any problems with collision checking (like the knight getting stuck in the wall when it moves too fast), try putting Collision Detection Mode on the Rigidbody2D to continuous mode. This makes the physics check for collisions more often and helps with those kinds of problems.

10 seconds into the video and I already see the huge amount of effort put into this. Mad respect for you, please keep up the good work!

[EchoNoctua]

Thank you so much! I've been putting off starting to learn how to make video games for so long because it all seemed so daunting, and I didn't know where to start. This helps immensely!

[ronanstark]

This one comprehensive tutorial was literally the answer to all of my problems. I had done some of the UnityLearn badges (which I highly recommend for a true beginner) but was still confused. Thank you so much for your time and effort in making this video! It's very much appreciated from a struggling student.

[qetqetqtzccvqdsioeiq]

Thanks to you I landed my job in the industry. God bless you Chris.

[BrickCube]

Absolutely awesome video, Chris! Thanks a lot for all your hard work making it!

[Khoura]

Just found this video and it is absolutely amazing, thank you for this I'm a beginner and I can't wait to get stuck in. If you are looking to make another series, I would love to see a Turn-Based RPG course, that would be pretty cool. Anyway, thanks again dude!

[RetroGaming-colm]

just now completed this series thank you sp much it helps me alot as a beginner i wish you could back to unity thanks for all your hard work to teach us

if your idle animation quickly flashes while ur changing direction, go to the player_walk to player_idle transition and set transition duration to 0.1 and interruption source to next state. Do the same with the player_run to player_idle transition.

Thank you Chris, it helps me so much learning Unity

OFFICIALLY WRAPPED THIS UP!!! THANK YOU SO

1:43:55 was this a mistaken cut? You suddenly switch gears from adding the RigidBody2D component and adding a FixedUpdate method to starting the TouchingDirections script from scratch.

I am also finding this section quite hard to understand. You've suddenly introduced a lot of terms I've never seen, or at least not in this context.

[leedavis]

I never used properties bc I never found them useful...until this vid, 1:00:00 in. Not sure why other vids did not show the actually usefullness of them but now I see. Thank you.

[NotaSWE]

Watched every second, thank you so much for helping me level up 😎

[Jeea]

Bruh, I respect, salute you for this tremendous effort and covering everything all together in one video/series. I will take a leap of faith, (create a copy of my game first) and delete all my previous scripts and follow this a to z! Best of luck to me!! Onwards!!

This tutorial is great! I plan on using it for the foundation for any 2d platformer I work on while I am learning Unity.

In case anyone runs into an issue with their knight flipping incorrectly or walking off the edge after setting up the cliff detection, make sure you have your WalkableDirection set to {Right, Left} and not {Left, Right} and to be extra safe set _walkDirection to WalkableDirection.Right when you initialize it. I spent hours trying to figure out why my knight would walk off the cliff backwards or double turn when hitting the first wall. If you don't set the default it will default to the first value in the enum, and for me that was Left, and I was moving right, so the first time I switched directions, it kept moving me in the same direction, causing weird behavior

If anyone is wondering why the parallax is working backwards(meaning the farthest background moves the fastest) the reason is because when we enabled the cinemachine asset it initially starts in the negative Z direction causing the farthest background to actually be the closest to the camera. The solution is to find Cinemachine in the hierarchy and set the Rotation Y to 180. Because the camera is flipped everything is now flipped as well. Go to your player sprite renderer and click the Flip in the X direction to flip your player. Now your player velocity is in the opposite direction so to fix this go into your Player Controller Script and find "rb.velocity". Set "rb.velocity" to "new Vector2(moveInput.x * (CurrentMoveSpeed * -1), rb.velocity.y);". From there adjust your backgrounds and everything should work like normal :)

Ma boi, I really am thankful for the effort! Very good explanations, very detailed.

Can you make video about quests/trading system? Or maybe some improved movements, like dashing, wall jumping, double dashing?

[PixelBard]

How do you set up your Visual Studio to get such detailed autocomplete suggestions? My VS autocomplete is not as powerful as yours. Please help. :(

I think your Parallax section should be reworked a bit. It's easy to follow until you start setting the BG's Z values. When you do that, you're looking at the back of the scene. Notice how the player is facing to the right, but once you start showing the view and changing the background Z values, you've now flipped everything around and the player sprite is facing to the left? I believe this is the source of the confusion in the comments around the parallax effect not working. The viewers have probably had the sprite facing to the right still since that's what they're familiar with in your tutorial until now. When they move the BG objects further behind the player, it will be increasing the Z values. However, since you've flipped the scene, when you move the BG objects further behind the player, it will be decreasing the Z values. The ParallaxEffect script you've coded works when the Z values are negative to represent being further away from the player, but to the viewer this would show up as closer if they modify the values directly and don't use the movement tool to move them behind the player. If they use the movement tool and have the scene facing the opposite of yours (which is how it has been shown until now), then they will get an incorrect parallax movement, which has the BGs that should be closer to the player moving faster.


You can fix the parallax movement by adding a negative onto the parallaxFactor to reverse the movement you have:
float parallaxFactor => / clippingPlane;

I'm new to Unity, so I'm not sure what the standard is on if Z values being positive or negative should mean they're further off the screen. Is there even a standard? I guess it could just be left the the developer's own preferences.
