LÖVE Audio Effects Playground

I actually thought about that - allowing the user to rewire things however they want - but since it doesn't change the outputted audio it would just be confusing.

That's very cool indeed! Extra points if the cables are shaped like a catenary

[ReFreezed]

It's more or less two sines added together which I don't think counts as a catenary shape, so no extra points I guess.

[pgimeno]

I don't blame you, it gets really complex. Still very cool though.

The use of sines was a bit surprising. I thought you would have used Bézier curves. It's what I would have used probably.

I just needed the cables to sag a bit, and sines have those saggy bits! No idea that shape this actually is.

Code: Select all

-- (hiX,hiY) is the higher connection on the screen.
-- (loX,loY) is the lower.
for segment = 0, SEGMENTS do
	local tx  = segment / SEGMENTS -- Move linearly on x.
	local ty  = sin(tx*TAU/4) -- Quickly approach lower y (ty=1).
	local sag = sin(tx*TAU/2) * MAX_SAG -- Sag in the middle.

	local segmentX = lerp(hiX, loX, tx)
	local segmentY = lerp(hiY, loY, ty) + sag
end

Well, extending a line reveals the true shape.

Awesome little educational tool! I usually can't keep up with the Games subforum, but this is great.

Thanks

I was bothered by the fact that the sine waves straighten up unnaturally near one of the ends, so I ended up making a parabolic version. A parabola is a decent-ish approximation of a catenary in many cases.

(Rename to main.lua to test)

That's nice. I'll save that code for the future.

In the program, the cables swing back and forth a bit. Could you implement physically correct swinging as well? (Just kidding.)
