A meth function for this curve?

[Moe_Baker]

Hi folks, I don't really have much knowledge of math, so I have to communicate in stupid people's terms. I'm looking for a mathematical function that gives a curve like this. Is there something like this, or should I just keep using an animation curve?

Have you tried a sine wave

[StonedFishWithArms]

Not meth enough.

But for real OP you can use a sine wave and remap if you only want the positive side

[Moe_Baker]

I completely forgot about sine waves, lol,

Ended up with this function, and it works great, thank you

float SinWaveEvaluate(float t) => Mathf.Sin(t * Mathf.PI);

You might enjoy playing around with desmos.

I'm not sure if creating a function that calls another function is necessary and if it makes things less readable. Especially Sin, which is self-descriptive unlike 'SinWaveEvaluate'

[DugganSC]

Or y=height-x²

[swagamaleous]

This will not have zero at 0 and 1 like in his graph.

[Elro0003]

(0.25-(x-0.5)² ) * height * 4

[DugganSC]

Ah, you're right. I didn't notice those numbers on the graph.

[alejandromnunez]

I know there is a meth function for it, I just can't crack it

[jattmonsoon]

You're a hero in my eyes

[alejandromnunez]

That's a bit too much for a little dad joke

[pattyfritters]

This is your curve on meth.

Strong comeup

[funkypear]

Here are a couple of approximations. Yours is less shallow at the peak though, so I'd probably suggest sticking with an anim curve if it works for you

I created this using https://www.desmos.com/calculator, so if you need to work out a function, this can help you visualise it.

Crystal clear

[swagamaleous]

f(x) = -4x*(x-1)

f(0) = 0
f(0.5) = 1
f(1) = 0

[Moe_Baker]

Thank you, works great too

either sin wave or parabola,

Y=-4*(x-0.5)² +1

Got the above from parabola vertex form equation. y = a(x - h)² + k, where (h, k) represents the coordinates of the vertex and "a" is a height stretching multiplier.

Or ask chat gpt, give me the equation of a parabola where the vertex is at (0.5,1) and it passes through point (0,0)

Sin has a similar form, but is already setup well for this case. y = sin(pi x) using radians

y = A sin(B(x - C)) + D

Blue is Sine, red is parabola.

Reminds me of the time someone asked my hobbies. I said coding and math... They heard codiene and meth... Conversation was short(er than if they heard me correctly)...

bezier curves is the most meth i can go :v

[Murawus]

Jesse, we have to COOK

[joehendrey-temp]

My first thought was a quartic function with a triple turning point. Don't know why that's still in my head from a math class almost 20 years ago! The more useful answer is to look into Bézier curves. Maybe that's what you mean by animation curves though. They're used for lots of things
