Useful functions for Game Designers: Easing Functions

[@mikiex]

Smoothstep ! :)

[@TheArtofCodeIsCool]

You got it!🤠

[@AndreLaBranche]

Easy for you to say! You're literally making it look easy. Anyway, take it easy. Ease out.

It's always a great day when Martijn blesses us with a new video

[@jokerpb4778]

I use these functions almost everyday. Now all mystery goes away about how they work!

[@sonu-jangir]

Thank you very much for this helpful video.🎉❤

[@realcygnus]

Cool ! Extremely important basics

[@MrSefsdf]

Just commenting to feed the YT algorithm. Please keep up your excellent work, truly appreciated

[@ricopin]

perfect timing. just so happens that I work on a game right now that needs some non linear movement :D

[@adriancardenosocerezo]

You are a really genius. This videos are all very cool!!! Thanks very much. I am learning very much !! :) (14:12 --> smoothstep()!!)

[@sea-saw]

Lerping two functions was neat, but dropping smoothstep into another function as the input blew my mind.

[@metalmastery5460]

I like your videos so much! Your lessons changed my perception and now everything is a function of something or a distance to some point.

[@TheArtofCodeIsCool]

That's awesome! The way I think of it is that functions encode a relationship between two or more properties.

[@neodos]

Fantastic tutorial and resources, thanks for making and sharing this, in Unity I use the visual curve widget(AnimationCurve) to tweak float or Vector3 variables with similar curves to those functions, but it's definitely better to know and understand the math.

[@TimWalton0]

The explanation is easy to follow, but imagine just stumbling upon that code one day and trying to work out what the hell it's doing!

[@TheArtofCodeIsCool]

Luckily I made a video about it ;)

[@purplehierophant]

Clear and demonstrative as always

[@purplehierophant]

This occurred to me when watching your 'Most Important Function...` video which had a lot of overlap, but figured I'd ask on this more recent video-my experience in procGen noise and images is people use Perlin's SmootherStep rather than SmoothStep. Is using the earlier/simpler polynomial to keep it clear for teaching? Or is there performance concern (as it's used hundreds of times) versus the modest improvement of the smoothing?

[@greje656]

Great topic!

[@Pracedru]

Very nice !!! Love those dancing letters. Didn't notice before now. I made a port of the rain shader to Godot btw :)

[@TheArtofCodeIsCool]

Awesome! Got a link?

[@Pracedru]

@@TheArtofCodeIsCool yeah but KZbin removes links from the comments

[@Firelordoli]

thanks for the cool tutorials

[@bradhammond923]

Thanks for the great vids.

[@BSGOST]

It seems to be a mistake in the formulas. You can check at 22:22 (for n = 2 and k = 2) there is no extremums, but at 23:25 there are two of them at the start and at the end according how yellow dot is moving.

[@TheArtofCodeIsCool]

Looks like it! I did some investigation on this and there actually ARE extremums for n=2,k=2 on Desmos. They are just hard to see.

[@adix64]

Very very very Useful! 👏

[@CoolJosh3k]

I have previously used “smooth” to give my RNG results some bias character.

[@kafel4796]

a blue dot function is a cosine function right?

[@NikolaNevenov86]

Nice, for long time I wondered how to animate my shaders with controlled curve. Now I know. Thanks! That being said....I suppose we could also do a bezier quadratic or cubic function and control the smooth curve directly by imputing the curve handles? If we want a more specific look.

[@TheArtofCodeIsCool]

Easing functions are nice because they are simple. But if you need more control, then absolutely Beziers are great. I'll do a video about Bezier at some point.

[@odinmagick]

I like to use “ease into the highway, ease out of the highway”

[@kostasismename9493]

thanks chad

[@hawns3212]

14:04 Is this smoothstep on the interval 0 to 1? Or is it different?

[@TheArtofCodeIsCool]

That right 👍

[@mohammadhomsee8640]

Function name is smoothstep 😉

[@reubenstarsky7328]

easy out to dance

[@babelchips]

If this video was a curve where 0 < x < 1, it’s definitely a 1
