How do I put restrictions (done with curly brackets in desmos) on functions in touch Lua

[Ollie]

Never mind I was looking for derivatives

Alright I figured out what I'm going to make. A game called freakout. Catch the sparks that appear when you catch them. Sometimes no sparks appear, sonetimes three appear. Loose points if you loose sparks, gain points if you catch them.. loose all the sparks the games over.

I don't know how to program or do math, but I'm a good listener takes me about a day to figure stuff out.

What does this mean?

vf stands for vertex format.
when your draw, you are required provide an array of vertices to draw (alongside with basic primitive shape type).
p2c4 says each vertex I provide for drawing is composed of two position components (axis) x and y, and four color components (red, green, blue, alpha)
(each component is provided as float value in the vertices array)

Cool. Can I publish a website with socket?

Hey how do I apply multiple values say from 0 to screen height to variables

[14sum]

draw.setscreen(1)
draw.getsize(width, height)
for x= 0,width do
x = x + 1
end
for y= 0, height do
y = y + 1
end
draw.point( x, y, black )
draw.point ( s, f, blue )

Why isn't height and width showing up as a number?

[14sum]

draw.setscreen(1)
width, height = draw.getsize()
x = 0
y = 0
for x= 0,width do
x = x + 1

for y= 0, height do
y = y + 1

draw.point( x, y, draw.black )
end
end

How do I make it so the points all come up at once?

[14sum]

a = 40000
w = 20000
t = 10000
v = a *
math.sin((2*math.pi*t)/w)
mo = {v}
audio.playbuffer( mo )

What does the error message mean on this?

[14sum]

url = require("socket.url")
draw.setscreen(1)
width, height = draw.getsize()
draw.string( "welcome to sure social", width-((1/2)*width), height-((1/4)*height), draw.black)

Why isn't my string showing up?
