### Re: Any subset sub calculator that considers multiplication?

One way to understand it is similar to a TV contest where contestants need to get as close as possible to a given number, by using only a set of numbers and using the four classic arithmetic operators on them Uuuh actually you're pretty close... I'm playing on a minecraft server (shame on me :ehem:...

### Any subset sum calculator that considers multiplication? [clarified]

I'm searching for some code that would allow me to do the following : (it's just for myself to check values, I only need to use this alone) [EDIT] Rules : 1. User inputs an array of @numbers, and a @goal 2. The code searches for sums of @numbers that would match @goal value, following these rules : ...

### Re: Function to find these 4 points? (simple math problem)

for i = 1, 4 do point.x, point.y = -50*math.cos(i*math.pi/2), 50*math.sin(i*math.pi/2) point.otherData = [...] table.insert(points, point) end Looks perfect for me! All the operations are written next to x and y without touching the loop :awesome: But positive y is bottom, not at the top. I actuall...

### Re: What sites do you recommend for hosting your screenshots and game?

ImageBB urls don't directly link to the images.
You have to get on your image's page, then "open the image in a new tab".
If there's the file extension at the end of the url, then this is the right one.

### Re: Function to find these 4 points? (simple math problem)

Are you planning to add more points later? These are particles, and the full loop looks like this : function particleEvent(x,y) for i=1, 4 do table.insert(particles,{ posX = x + (50*i-150)%100, posY = y + (50*i-100)%100, particleData = ..., particleData2 = ..., etc. }) end end I could simply have d...

### Function to find these 4 points? (simple math problem)

I have a point A (x,y), and want to generate 4 points around, like this : https://i.ibb.co/NLR9Jm1/prob.png (A here is [0,0], but could have different coords) I want to generate them from a for() loop into a table, so it would look like this : function genPoints(x,y) --Coords of A local points = {} ...

Guess I'll use a table for that then... hopefuly, there're not many places in my game where I have to change this (so far...)

### What's best to keep a value for only 1 frame?

I'm storing keypresses detected from love.keypressed() into the var "KEY" (for other functions), but only need it for 1 frame, and so I added "KEY = nil" at the end of love.update. So, is it better to have "KEY = nil" there, or "if KEY then KEY = nil end"? Wou...
