Finally a new episode from the best tutorial!

[@protokron5037]

I was worried you stopped this series. I recently started learning Unity with the intention of implementing a similar game (top down Towerfall). Thank you so much for doing this.

[@CouchFerretmakesGames]

No way that I'll stop the series. :D I just had some troubles setting up the studio. :)

Amazing video! Love the new format, it's surprising how seamless the IRL sections mix with the screen captured ones. I loved your explanation of hit detection using markers/paper; very through, easy to follow, and drawing it by hand gives it a nice grounded touch. The amount of polish you put into your videos is always impressive, down to the small things like the plants on your desk. Keep up the good work, and I'm excited to see more!

[@CouchFerretmakesGames]

Thanks! I'm glad you noticed the plants, I aligned them to the corners way too many times. :D Yeah, I really enjoyed creating and editing the markers and paper part. And the markers' sound is just outright satisfying. :) I'll definitely have more of this. Thanks for watching!

Best topdown 2d Unity Tutorial Ever! Love, man!

[@MrQuicast]

Your videos helped me a lot, I thank you so much, I know your channel will keep growing, and I hope you can upload more videos, for example to implement AI for the enemies or how to design transitions of scenes or also how to interact with objects or people , also how to create a game menu, so many things that could be implemented in a game. Thank you for your help in advance, a greeting from Peru.

[@CouchFerretmakesGames]

I'm glad they helped. :) I'll cover all of this in the future. Thanks for watching! Cheers!

[@kailastnam9793]

Nicely done! I think the way you handle the raycast origin could be better though. you could design a variable for raycast origin and raycast direction. Try to keep code/collision seperate from the sprite. Great job as always, and I like the new style.

[@CouchFerretmakesGames]

Thanks for the feedback, noted! :) I try to balance simplicity and structure so the videos remain beginner friendly, but still a reasonable design. I guess I'll separate them when they become a bit more complex.

[@loganjones3723]

You are one of my favourite KZbinrs!!! So nice and clean videos make it easier to understand. Keep the good work up 👌❤️

[@CouchFerretmakesGames]

Thank you! ^ - ^

[@user-em9su3dd9y]

Cool setup, great info too!

[@irishbruse]

So do you have any kind of a schedule for these videos im loving them there are so polished im past this level of tutorials but i just love watching them while i program my game :)

[@CouchFerretmakesGames]

I always aim for weekly videos, but stepping up the quality takes a lot of time. I plan to settle with this episode's quality so I can upload more frequently. Thanks for watching, and good luck with your game! Let me know if you have something to show! ;)

[@fastpicker89]

1) Hurry up with the next video! These are amazing! 2) Any reason that instead of offsetting the arrow to match the player's rigidbody -- couldn't you create one rigidbody that only applies to walls, and another that applies to arrows?

[@CouchFerretmakesGames]

Thanks! :) Could you elaborate on #2? I don't get it. :/

[@GuilhermeMaia100]

Good tutorial. What i was thinking is : is there a way to automatically pass the velocity and the archer to the arrow while it is instancing? Like a constructor for example instead of having to use GetComponent every time time you instantiate the arrow

[@bluegoodev2085]

Hi CF! Great tutorial as always and the quality and camera angles are amazing, also love the pen and paper approach! I have a thing I’m thinking about in my game which has a similar perspective as yours. Should arrows/bullets ever pass behind the player/enemy? Or should the hitbox always be the full size of the player? It would add depth and realism to have bullets go behind, but I can’t figure out how the hitboxes should look. I’m thinking about using a ground hitbox on each bullet and a hitbox on the player which is from his feet to his knees. Haven’t tested it yet, but do you think it could work? :)

[@CouchFerretmakesGames]

Yeah, I think that would work. However, this issue is very tricky, I've straggled a lot with it. You don't want to have it too realistic to the perspective, because then the players could think that it is unfair and broken when an arrow goes behind an archer. I made a proof of concept version of this game like a year ago, and if I remember correctly, I had a separate collider on the archer that was only used to detect the arrows, and it was a bit bigger. It wasn't full archer sized but like half of it, and definitely bigger than the one I used to collide with walls. And the arrows used raycasting which was offset to the ground just like in this video, but instead of simple linecast I used circlecast. With circlecast, basically you can add width to the rays. I'll address this problem in the future, but I think I'll go for a solution between the realistic and the full archer sized collider. Cause it seemed to me that the full realistic version like the one we have in this video could seem bit unfair and broken. Good luck, and let me know what did you end up with! :)

[@bluegoodev2085]

CouchFerret makes Games Thanks for the detailed comment! I didnt realize you wrote so much :) I will let you know once I’ve implemented shooting in my game :) Looking forward to future videos!

[@CouchFerretmakesGames]

@@bluegoodev2085 Thanks man! Good luck!

[@ThomasChen-ur2gt]

I am trying to apply a force to the player when it gets hit, but it's not working because we are resetting the velocity every frame. How can I get around that?

[@CouchFerretmakesGames]

Ohh, that's a tough one. I'll look into it.

[@mayankbhaisora2699]

Hey man… Is there any budget game controller which you would suggest to play and test games on M1 macbook?

[@fernandopinto4393]

What a man !!!

[@reed9269]

at first i thought that arrow would continuously cast raycast infront of it and if it's lenght would be say less than 0.01 it wold collide, do you think it could work?

[@CouchFerretmakesGames]

Actually, that could work, yeah.

[@UnicGamesReviewsmore]

Hey man, i just started with yout animation tutorial for windows. What i liked about ist was the xlear structure and that it seems like you know exactly what you do. But please try to speak a little bit slower and give us little breakes between the steps. So we can think about what you just did ans try to understand everything. Also it would be cool if you can explain the code scripts more. Thank you for your effort. :)

[@CouchFerretmakesGames]

Roger that! :) I have to find a way to slow down while avoiding being boring. But I'm working on it. Thanks for the feedback! :)

[@mohammednihad6755]

Thanks a lot you can also use Rigidbody.collisionDetectionMode I think setting that to "Continuous" will also help solving the problem :)

[@CouchFerretmakesGames]

It definitely solves the first problem, but I'm not 100% sure that it solves the second problem with the archer behind the wall. I have to double check it, maybe I'll make a quick little video and/or gif about testing the different collision modes and raycasting solutions. That would be fun. Thanks for the feedback! :)
