Why can't you call a number value?
I am writing a script to switch between pages for a Spell Book. When I try to switch pages, the code I think should work throws an error saying:
Players.smash1975.PlayerGui.SpellBook.RightFrame.Back.Handler:68: attempt to call a number value
The line which is throwing the error is:
1 | button.Parent.SpellsL.Text = getPage(page,0) |
The function "getPage" is:
01 | function getPage(page,side) |
02 | if tonumber(page) >= -1000 then |
03 | -- Page is a number (Is hardcoded so always should be) |
04 | local p = pages |
05 | for x=1,#p,1 do |
06 | if side == 1 then |
07 | if p[x] == (page+math.floor(side)(page-1)) then |
08 | -- Found correct page |
09 | local ret = "" |
10 | local c = p[x+1] |
11 | for i=1,#c,1 do -- Convert list to string |
12 | ret = ret..c[i].."\n" |
13 | end |
14 | return ret -- return string |
15 | end |

The error is being throw when I try to call "page" to alter the position in the list that I get the string from. (Line 7)

Originally, I did not separate the code into if side == 1 and else, but I was just trying to see if the value of 0 was the issue. It is not. appxritixn 2235 — 5y

if p[x] == (page+math.floor(side)(page-1)) then
"page+math.floor(side)" is a number, by doing "(page-1)" it thinks you're trying to call it like a function but we know it's a number value. I'm not sure what you want to put inbetween there, or if you just forgot but it should look something like this.
1 | if p[x] == (page+math.floor(side)+(page-1)) then |

I can't believe I didn't notice I was missing an operator. I feel like an idiot. appxritixn 2235 — 5y

It's okay, I'm just glad it works! CeramicTile 847 — 5y
