Bored due to Social Distance, made this for the heck of it

Here's a simple programme made to calculate the amount of paint (&& layers [*sh joke]) required to completely fill a room with layers of dried paint.

It's written in Python3.8, (I know it's pseudo-code, but it gets the job done)

Here's the source :

Code:

'''


Name : paintRoomCalc.py


Desc : Calcualate how much paint to fill a room

from colorama import Fore, Back, Style








def getLayers(roomWidth, roomDepth, roomHeight, paintThick):


    i = 0


    t = 0


    roomWidth = roomWidth * 12


    roomDepth = roomDepth * 12


    roomHeight = roomHeight * 12


    roomVol = roomWidth * roomDepth * roomHeight


    while roomVol >= 0:


        #account for walls


        wallOne = roomWidth * roomHeight


        #print("wallWidth : "+str(wallOne))


        wallThree = roomDepth * roomHeight


        #print("wallDepth : "+str(wallThree))


        wallFive = roomDepth * roomWidth


        #print("wallCeil : "+str(wallFive))





        wallVol = (wallOne * 2 + wallThree * 2 + wallFive) * paintThick


        wallArea = wallOne * 2 + wallThree * 2 + wallFive





        roomWidth = roomWidth - (paintThick * 2)


        roomDepth = roomDepth - (paintThick * 2)


        roomHeight = roomHeight - (paintThick * 2)





        #account for edges going up & down


        edgeUpVol = roomHeight*paintThick**2


        edgeUpVol = edgeUpVol*2


        edgeUpArea = roomHeight*paintThick


        edgeUpVol = edgeUpArea*2





        #account for edges going side to side {on ceiling}


        ##account for edges going side to side {depth}


        edgeSideDepthVol = (roomDepth*paintThick**2)


        edgeSideDepthVol = edgeSideDepthVol*2


        edgeSideDepthArea = (roomDepth*paintThick)


        ##account for edges going side to side {width}


        edgeSideWidthVol = roomWidth*paintThick**2


        edgeSideWidthVol = edgeSideWidthVol*2


        edgeSideWidthArea = roomWidth*paintThick


        


        #add edges


        edgeVol = edgeUpVol+edgeSideWidthVol+edgeSideDepthVol


        edgeArea = edgeUpArea+edgeSideWidthArea+edgeSideDepthArea





        #calculate final values


        roomVol = roomVol - wallVol - edgeVol


        wallArea = wallArea - edgeArea





        i += 1


        t += wallArea


    print(Style.RESET_ALL + Fore.LIGHTMAGENTA_EX + str(i) +


          " layers to fill your room with paint!!")


    print("& " + str(t / (4800)) + " gallons of paint")








print(Fore.LIGHTGREEN_EX + Back.BLACK + "Paint Layer Calculator")


print("by : Аїӡек Меѥҏ")


print(Style.RESET_ALL)


roomWidth = input(Fore.BLUE + "Room Width in Feet? ")


roomWidth = int(roomWidth)


roomDepth = input("Room Depth in Feet? ")


roomDepth = int(roomDepth)


roomHeight = input("Room Height in Feet? ")


roomHeight = int(roomHeight)





print("\n")


print(Style.RESET_ALL + Fore.RED + "1 mil is 1/1000 of an inch")


paintThickMil = input(Style.RESET_ALL + Fore.BLUE +


                      "Paint Thickness in Mils? ")


paintThickMil = int(paintThickMil)


paintThick = paintThickMil / 1000


print("\n")


print(Fore.GREEN + Back.BLACK + "Calculating...")


getLayers(roomWidth, roomDepth, roomHeight, paintThick)

As you can see, it does ANSI terminal colours as well, b/c paint's colourful.

Here's a demo of it running :

NOTE :
An average single coat of paint averages 'round 1-2 mil (one mil is one one-thousanth of an inch)

EDIT :
I added in calculations for the edges, thanks to MateoConLechuga's Idea

Double posting 'cus it's been a day

Mateo, you're gonna hate me for this, but I ported the code to Node.js, yay, efficiency.

Code:

const prompt = require('prompt-sync')();


const colors = require('colors');





function getLayers(roomWidth, roomDepth, roomHeight, paintThick) {


  var edgeArea, edgeSideDepthArea, edgeSideDepthVol, edgeSideWidthArea, edgeSideWidthVol, edgeUpArea, edgeUpVol, edgeVol, i, roomVol, t, wallArea, wallFive, wallOne, wallThree, wallVol;


  i = 0;


  t = 0;


  roomWidth = (roomWidth * 12);


  roomDepth = (roomDepth * 12);


  roomHeight = (roomHeight * 12);


  roomVol = ((roomWidth * roomDepth) * roomHeight);


  while ((roomVol >= 0)) {


    wallOne = (roomWidth * roomHeight);


    wallThree = (roomDepth * roomHeight);


    wallFive = (roomDepth * roomWidth);


    wallVol = ((((wallOne * 2) + (wallThree * 2)) + wallFive) * paintThick);


    wallArea = (((wallOne * 2) + (wallThree * 2)) + wallFive);


    roomWidth = (roomWidth - (paintThick * 2));


    roomDepth = (roomDepth - (paintThick * 2));


    roomHeight = (roomHeight - (paintThick * 2));


    edgeUpVol = (roomHeight * Math.pow(paintThick, 2));


    edgeUpVol = (edgeUpVol * 2);


    edgeUpArea = (roomHeight * paintThick);


    edgeUpVol = (edgeUpArea * 2);


    edgeSideDepthVol = (roomDepth * Math.pow(paintThick, 2));


    edgeSideDepthVol = (edgeSideDepthVol * 2);


    edgeSideDepthArea = (roomDepth * paintThick);


    edgeSideWidthVol = (roomWidth * Math.pow(paintThick, 2));


    edgeSideWidthVol = (edgeSideWidthVol * 2);


    edgeSideWidthArea = (roomWidth * paintThick);


    edgeVol = ((edgeUpVol + edgeSideWidthVol) + edgeSideDepthVol);


    edgeArea = ((edgeUpArea + edgeSideWidthArea) + edgeSideDepthArea);


    roomVol = ((roomVol - wallVol) - edgeVol);


    wallArea = (wallArea - edgeArea);


    i += 1;


    t += wallArea;


  }


  console.log(colors.magenta(i.toString() + " layers to fill your room with paint!!"));


  console.log(colors.magenta(("& " + (t / 4800).toString()) + " gallons of paint"));


}


console.log(colors.bgBlack.green("Paint Layer Calculator"));


console.log(colors.bgBlack.green("by : Аїӡек Меѥҏ"));


console.log("\n")


let roomWidth = prompt(colors.blue("Room Width in Feet? "));


roomWidth = Number(roomWidth);


let roomDepth = prompt(colors.blue("Room Depth in Feet? "));


roomDepth = Number(roomDepth);


let roomHeight = prompt(colors.blue("Room Height in Feet? "));


roomHeight = Number(roomHeight);


console.log("\n");


console.log(colors.red("1 mil is 1/1000 of an inch"));


let paintThickMil = prompt(colors.blue("Paint Thickness in Mils? "));


paintThickMil = Number(paintThickMil);


paintThick = (paintThickMil / 1000);


console.log("\n");


console.log(colors.bgBlack.green("Calculating..."));


getLayers(roomWidth, roomDepth, roomHeight, paintThick);

"Yay efficiency"? Javascript isn't inherently any better than Python.

(I quite like Python.)

I meant I'm able to push out a transpiled program pretty quickly because the languages are so similar
