1. Like the video
2.. watch it
3. Respect this awesome man for his awesome videos

[@applegravity9843]

Apples bouncing around, I really relate to this video ...

[@Holobrine]

You could restrict the angle that a segment can be from another, so they never overlap and the tentacle has some form of rigidity.

[@eduardoalvarez6257]

How!? I'm trying to implement this idea for two days... xD

[@Zetta1Reid0]

It is pretty easy actually . Just make a function that accept the bone angle ,then check if bone angle is bigger then maximum value , and if the bone angle is > maximum value to return your max angle.

[@yahyadadshah9408]

watching your videos makes me love do more coding 😃

[@aminthemar]

14:28 They're playing basketball at the end

[@bbugarschi]

basketapple you mean...

[@rock4459]

But i think they forgot about the basket 😅 ​@@bbugarschi

[@playboy1103]

laughed really hard a few times. great job. loved it.

[@Danacus]

That's so satisfying to watch!

[@nagualdesign]

Interesting that when the apple moved from out of reach, with the arm perfectly straight, to within reach, the arm zig-zagged, with segments alternately bending clockwise or anticlockwise.

[@mrfincher]

Awesome! :D

[@noelearlwatson2724]

Nice

[@realcygnus]

superb

[@Michael89240]

Woah. This channel grew so fast. I remember this only had 10k subs

[@kuskus_th13]

Michael Lin I remember it having 90k.

[@cunningham.s_law]

i crave these videos

[@kokorogames61]

Hello! I actually opened TH-cam with the purpose of writing an idea to you to make a video about IK. First I searched to see if you already had a clip about that and of course you do. I'm going to watch the other IK clips of your too. Are you planning to make any clips about IK constraints? Like limiting the angles of segments? Or even IK in 3d? This is even more interesting with constraints. I watched tons of your clips, I am forever grateful.

[@yohannjolain77]

Nice video, it's really nice :)
There's just a little thing, I want to point. Why, when you instanciate your ArrayList, you don't use the diamond operator? (Available since Java 8)
You're declaration of an ArrayList becomes:
```java
ArrayList tentacles = new ArrayList();
```
It's nice and avoid some typing :)
But keep working, i like those challenges!
EDIT: Why don't you support markdown TH-cam... it's nice when we want to show some code

Coding Challenge! Inverse Kinematics PONG! One player controls the kinematic arm with the mouse instead of a paddle. If the puck gets within a certain distance of the end, it counts as a catch. If you miss, the other player gets a point. If you caught the puck, you click and drag (Angry Birds style) to set up a serve to the other side.
The AI, on the other side, just follows the mouse, but with limited speed.

[@cirocayodeleonburgos7900]

u can crete a next coding challenge about navier stokes equations.

[@raphschru9865]

Simulate liquids, great idea !

[@kim15742]

Oh, yes! My dream!

[@kiddopediabysaharshevan5060]

Da Bobby roast😂

[@komeny]

please do zentangle patterns!

[@ilyakosarev9189]

Hello. Please make a lesson on how to make angle constraints in this IK system.)
Have a nice day!

[@arjunpalusa9421]

Hi , Could you please share total background of Inverse kinematics , All mathematical formulas working in background, Not commands.

[@PaulGoux]

Not sure if this can help, ive implemented this idea without any vector functions, might be worth checking out, its 95% done just a few things to iron out but otherwise it works well.

It's uploaded 2 mins ago with comments 1 day old what even is this?

[@misode]

What is the outro music?

[@kuskus_th13]

His "theme song". Search "Welcome to undefined"

[@robinkelmen6332]

Can you make a robot with limbs that use Inverse Kinematics that also reacts to gravity?

[@Holobrine]

8:11 Dude, that’s a basketball hoop.

[@cervi6538]

A coding challenge 1st person camera 3d videogame

[@aimenmansouri7648]

that was java or js ?

[@mrduck7957]

I believe it's Processing based on java

[@CarlinoGonzalez]

It is Processing, which is based on Java

[@aimenmansouri7648]

in passe chalenges he was programing with js did he wase use library or just js ?

[@YoutubeAdministrator]

he uses a library called p5.js in most of his js coding challenges.

[@CarlinoGonzalez]

TECH-AREA Aimen.m it's a JavaScript Library called P5.js. There are a lot of tutorials out there :)

[@Kino-Imsureq]

weird bcuz it dulplicated it.

[@slick8509]

create 8 ball pool basic please

[@curt8806]

For some reason I read it as testacles.
