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

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.

watching your videos makes me love do more coding 😃

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

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.

Hello! I actually opened YouTube 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.

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<Tentacle> tentacles = new ArrayList<>();
```
It's nice and avoid some typing :)

But keep working, i like those challenges!

EDIT: Why don't you support markdown YouTube... it's nice when we want to show some code

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

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

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.

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

[ilyakosarev]

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

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

[robinkelmen]

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

For some reason I read it as testacles.
