Unity Collision Cheat-Sheet - Discrete vs Continuous

[@MasterDavicous]

A fun trick I like to use in some instances is stretch the projectile's collider according to its velocity. This way it still detects collisions at high speeds on discrete mode! :)

[@Tarodev]

Oh wow, that's an awesome little trick!

[@alex.g7317]

sick

[@joscpe]

I know a thing or two about stretchy projectiles

[@alex.g7317]

@@joscpe Is this a dick joke?

[@JuniorDjjrMixMods]

Scale a collider is costly iirc. Maybe the cost is higher than the benefit.

Never pressed a notification so fast! Welcome back, Taro!!

Never pressed the like Button on a coment so fast ! Xd Hi IHGD

[@Tarodev]

Awww, thanks Nicky

[@dragonlance1121]

Nice! I have wondered about this for a while. There are so many Unity options that have no explanation tips, you could make a dozen videos like this easily, and I'd watch every one of them. By the way, you are mentioned in the Credits section of the game I am making, for all your great tutorials. Thanks!

[@Tarodev]

I'd love to play it when you're done. Come to discord and drop it in when you're ready :)

[@neilmarkcorre5524]

Straight to the point, impressive and easy-to-understand visuals, concise - overall a brilliant video! This deserves to be shared EVERYWHERE.

[@x-easy]

This is awesome! Daniel Irving had a good idea; putting you in the credits section of my upcoming game. Thanks a ton for what you do!

[@Tarodev]

I would be honoured to be in there ❤️ as I said to him, be sure to drop your game in discord so I can check it out.

[@MassimoRough]

Here! That's some high quality content in here! Was missing you, good job!

[@Tarodev]

Thanks for waiting 🙏

The quest for quaternions has envelopes tarodev so utterly completely, he may never be the same again.

[@Tarodev]

Very VERY soon my friend

[@Beldarak]

Thanks. I never took the time to ask myself what different modes did. super helpful and straight to the point :)

[@attenurmi936]

Concept explanation and video quality 13/10! Would watch again!

[@Tarodev]

That's a high rating my man

[@Chubzdoomer]

One of the best breakdowns of the collision types I've ever seen. Fantastic work as usual (and another great reminder why I've stayed subscribed to this gem of a channel)!

[@pavelholub6275]

This channel is piece of gem! Fast, simple, but explain enough to understand by almost everyone! I just love it.

[@Tarodev]

Had me worried reading "a piece of...". Glad you like it 😀😀

[@wayward8372]

Further to another comment - this video gives clarity, with clear, easy to understand visuals and example use cases and concise. Great.

[@dibaterman]

This... I have wall boundaries in my project, it's rare but sometimes when something moves too quickly they go through the wall. YT recommending this was so timely.

[@petpumpkin]

This is great, I'd love to see more dives into what the settings of components actually do

[@EngineersToGoMT]

Broooo !!! this here was helpfull. I didn't even know what was going on with my objects going through walls. This was too helpful

[@Tarodev]

Glad it helped you my man

[@Subreeze102]

Great execution on the short but informative cheatsheet video!

[@DanielAttaway]

Great timing, my current unity project sometimes has collision issues, and I expect it's related to discrete collisions. Thanks for the video

[@hamedbabamohamadi9017]

Missed you! glad to watch another amazing video from you.

[@ojassharma56]

Just brilliant, and so helpful. I would recommend these anyday to my junior devs who can learn from you just like once I did, and I keep learning from you everyday since

[@Tarodev]

Aww

So good to have another of your videos :)! I missed you already :D

Awesome! We're still waiting for quaternions though, please don't leave us hanging 🙏

Thanks Taro I'm beginner and always used continuous collision before. This video changed my mind. 😀🙌🏻

That was the exact thought I had in mind when making this video 😉

nice short video for beginners also you can make about collisions. When does happen ontriggerenter/oncollisionenter, what difference and etc

[@maxhuk]

Nice breakdown!

[@ceroenblanco]

Things I didn't know I didn't know. Thank you!

[@andreasmetz2438]

Best explanation I've seen by far. Keep up the good work!

[@Paul-Jean]

It is very well explained. Very useful cheat sheet, thanks. (The video support helps me understand better than just pictures and text.) Otherwise, I wonder, for the thumbnail image of this video, what type of font you are currently using? I love this typography.

[@Tarodev]

It's called 'You Blockhead'. It's the same font supercell uses. You can buy a license pretty cheap.

[@ishan9050]

Now this is what we call "Back with a Bang" Missed your videos...

[@MaskedImposter]

I had a tunneling issue with a parabolic projectile tunneling through the ground. I just decided to increase the size of its collider.

[@ShinichiKudoQatnip]

Woah, now this bite size info will go a looooong way for me. ❤️

[@aliengarden]

Great video, as always!

[@lakemonstergames32]

Beautiful presentation! It was so informative and concise.

[@ewwitsantonio]

Yay another tarodev video!

[@Tarodev]

Kept you waiting ;)

[@abdrnasr]

For the problem of ghost collisions with rotaion in speculative mode one solution that I can think of is to lag the collider of the rotating object based on its speed, so that when it ghost collides the actual mesh would be leading the collider.

[@jean-michel.houbre]

Very clear, thanks.

[@wicgamesdev]

ITS REALLY WORKED LOL THANK YOU DUDE

[@RootTheCoop87]

I don't know what I'm doing wrong, but no matter which option I choose and no matter how slow or fast the two objects are that have a rigidbody, they go right through each other if I add a script to them. Doesn't matter if I move the objects with transform or by the rigidbody. The only time they don't pass right through each other is to not add scripts to them, which is pointless when making platforming traps. I didn't have this problem until I switched to the newest version on Unity.

[@Tarodev]

That is... Bizarre. Does this happen with any script or a specific one?

[@RootTheCoop87]

@@Tarodev Any script, even scripts I've used in older builds of Unity with no issue. I bought a controller, but I didn't like it, removed it. I don't know if that changed some setting I've never used or seen before. That's why I rarely use Unity assets. The only time I've haven't had issues on a project, are ones without Unity assets.

[@trashcaster]

What is the best option to use in the case of a bullet-hell game or a game where a player may mod their weapons to fire 10s of projectiles per second, with 100s on screen? Ray Cast per projectile? Or the built in collider solution? I've attempted the raycast option before, but always had tunneling as well (as if the projectile just never "hit"), but with much better performance than rigidbody/colliders. I raycasted from the projectile, forward by units equal to the "travel speed" of the projectile, and even slow projectiles would occasionally just act like the ray cast missed
