Procedural Animation in 5 Minutes | devlog 1

The video is for creating a foot placement system, but I nevertheless spent a good portion talking about IK. This video is part of a devlog series but stands on it's own as a tutorial. If you need any help or have questions feel free to join my discord.

*Watches too many rain world videos*
"Hey, i should learn procedural animation!"
*Watches this video*
"Nope"

i'm a baby dev so i understood pretty much nothing, this was a great video.

Plays rainworld, decides to learn Inverse kinematics because of rainworld, met with more rainworld. Cool

[larsmaas]

This is a perfect and simple explanation of procedural animations!
I used this technique for my spider game. It was quite difficult.
Also great video just 5 minutes but still so much information.

slow down brother you are giving me anxiety

[lemonice]

4:20 of course you couldn't make procedural animation video without using Rain World OST

Holy sht. Such a complex thing, explained so concisely. I'm really new to game dev, and often need to watch a video a few times before I get it. But not here. (Don't worry, I'll still watch it a few times as I figure out how to implement this, I just mean you did an incredible job explaining it)

For anyone wondering, the v2::polar stuff is converting polar cords to cartesian cords, the first value is the angle the second is the radius. I got stumped on this for ages. Here's the code;
func polar_to_cartesian(angle, radius):
var x = radius * cos(angle)
var y = radius * sin(angle)
return Vector2(x, y)

Amazing presentation. Thank you for this.

Interesting topic. Have not come across this before, but the approach makes sense. And the effects are pretty nice. To get it even better I guess one would have to add a y component. So that the feet don't go in a straight line to the LERP point, but rather in an arc.

Dayum, I had to turn the play-speed down to .75x for this video, and the content was paced well and not slow at all. You really crammed a lot of great info into 5 minutes, and not a single ad! Great work man, thank you!
One thing I couldn't seem to get over is that you started the video mid-word and an image fleeing from the screen and so I kept starting the video over looking intently at what it was I thought I was missing lol.

[dootiepatootie]

Im not a game dev or anything but this stuff is so interesting

[SombreroMan]

Amazing video! Even though I somehow understood all of that, I feel hat if you explained with some visuals representatives, the explanation would be easier to follow.

[umbranocturna]

i will never use this, but great video

[michelecini]

Hey man is the next video on procedural animation still coming out? It’s a topic that’s not talked about enough… well, in depth enough at least

[Badsiner]

how do you make it so that when you have multiple softs in your soft roll; you arent interfereing with another soft like accidentally

[nulcow]

I'm very concerned that I have to learn how to implement this stuff if I'm going to develop a Spore-like game.

[equar]

Only if this resource was out when Randall was doing his IK stuff for arcana

[cirno]

at 2:26 is it supposed to say if L1 + L2 < d?

[comnrade]

i'm trying it to make organic animations for the enemies for my survival game, god damn i never tough it would be so fcking difficult to code a simple ankle
