hello i am hoping the answer is pretty straight forward and im to tired to realize it right now, but i have a table with 5 values and i would like to do something like

table={1,2,3,4,5}

if btnp(X) then table[i+1]

but also have it wrap back to 1 if the table index reaches the length of the table.

essentially a (for I=1,#table do) but only progresses if I press a button

so, do you mean that you’re storing a value from the table somewhere, and on button press you want to store the next value?

table={1,2,3,4,5}
thing_idx=1

def _update()
 if btnp(X) then
  thing_idx=thing_idx + 1 % #table
 end
end

% is modulo, or the division remainder operator

# is the length operator for tables and strings

so the code increments the index by 1, but wraps around depending on the length of the table :)

@merwok,
That's basically the same approach I use, but you need to be sure to add the 1 after running the value through the modulo instead of before, or your value will loop back to 0.

table={1,2,3,4,5}
index=1

function _update()
 cls()
 if btnp(❎) then
  index=index%#table+1
 end
 ?table[index],1,1
end

thank you for the responses! For clarity

ipipe={5,6}
lpipe={7,8,9,10}
tpipe={11,12,13,14}

function mk_pipe()
pipe={}
pipe.x=8
pipe.y=0
pipe.spr=ipipe[1]
end

function rotate_pipe()

if (btnp(❎)) then
--- here i want to be able to increment any pipe tables index by one up
to #pipetable before wraping back to index one
no need to append as these values will not change.--

@merwok
JadeLombax pointed out the first issue I was going to mention about your code. However, I'll also add that your code wouldn't have wrapped anyway due to operator precedence. % gets the same order as * and / .

@Razzputan
If you have an further need to post code, I suggest using the code formatting. It's a ``` before and after your code.
