Simple Code Knowledge 🧑‍💻

Variables
Functions
API Services

Variables are very important they’re named paths/values that can be accessed anywhere in the script.

Functions are blocks of code that can be ran once or multiple times

example

-- text param can be a string or a number
-- you can use : after adding a parameter for type checking which is very important for intellisense
function new(text: string | number)
 print(tostring(text))
end

new(2) -- prints 2
new("Hello World")

-- example of a countdown 
for i = 1, 10, 1 do
 task.wait(1) -- waits 1 seconds before continuing the loop
 if i == 4 then continue end -- this will ignore 4 and continue
 new(i)
end

-- this will print after the loop finished running
new("Loop Finished")

One thing you might notice is that “Loop Finished” will not print until the loop is finished if you wanted to counter this you can wrap the loop inside of a task.spawn() function like so:

task.spawn(function()
 -- example of a countdown 
 for i = 1, 10, 1 do
  task.wait(1) -- waits 1 seconds before continuing the loop
  if i == 4 then continue end -- this will ignore 4 and continue
  new(i)
 end
end)

-- this will print after the loop finished running
new("Loop Finished")

now “Loop Finished” will print before the loop actually finished this is useful for running multiple functions at the same time without stopping for a loop to finish.

API Services are super important for things like gamepasses and developer products they can also be used for a lot of other things like datastores which are used for loading and saving player data, Roblox Documentation explains their the API Services very well i recommend reading the Roblox documentation if you’re wanting to get serious into Roblox Development

Syntax 📜

Understanding syntax is very important for any programming language

What is Syntax? Simple definition “syntax is the “Rules” of a programming language”

example:

Wrong ❌

local p = t

Correct ✔️

local t = "randomstring"
local p = t

in this example t is not a valid value/path for our “p” variable we can fix this by giving t a value/path which can be almost anything some examples: boolean, string, and number.

How To Stay Motivated 💪

I understand what its like to feel burnt out or that you might think you can’t do it, this is normal. what matters the most is discipline a lot of people give up before actually getting anywhere in programming. If you want to stay motivated I recommend trying a few things first of all if the game is your problem try to think of what your game could be rather than what it is, I personally believe that no game is not fun for at least one person. If your personal life is the problem then focus on that first before trying to develop games! If its anything other than those issues like getting burn out then just take up a new side hobby or do something other than Roblox Development.
