Adding new die to existing dice collection

**Kelrugem** · June 16th, 2019, 00:45

Hi

I now learned how to code a trigger for dice rolls with their chat message etc., in my case a d100 triggered by an effect. However, the problem is that the number of d100 is arbitrary in my code (so, it can be that it has to be 2d100 instead of just d100) and that depends on the situation, like a DMG effect can add an additional die to the damage in 3.5e. I do not know how to add additional d100 to the existing one, I tried table.insert like I saw it in the coding of the DMG effect but that does somehow not work. To break down my code I try at some point in my code:

Code:

local bDice = {};
bDice = table.insert(bDice, {"d100, d10"});

But the outcome is only a nil value. I thought that I maybe insert the additional d100 wrong but replacing {"d100, d10"} with a "d6" (as string, I guess(?)) does not work, too, so this does somehow not work for other types of dice.

Do I use the insert function somehow wrong? I tried to do it similar to other parts in existing code but something is going wrong here for me

Best,

Kelrugem

EDIT: Oh, of course, bDice will be the variable defining the type of die of my roll, so it will be in some "rRoll" and rRoll.aDice = bDice (following the guideline in the comments at the very top of manager_actions.lua in CoreRPG).

To explain a bit more: When I look at bDice before table.insert (by using Debug.console(bDice)) then it returns the defined value, but after table.insert it is empty. So, e.g.

Code:

local bDice = {"d100", "d10"};
bDice = table.insert(bDice, {"d100, d10"});

results into bDice ={} at the end, so after table.insert its entries are completely erased for some reason which I do not understand

Looks like you’re trying to insert a table into a table, whereas (in theory) this should work as far as LUA is concerned, it won't give the correct format for FG. In FG code I haven't seen multiple dice added at once. Try inserting the d100 and d10 separately as two table.insert commands.

Thank you, I will try that

Ok, now I was trying

Code:

bDice = table.insert(bDice, "d100");
bDice = table.insert(bDice, "d10");

But then I get the error message

Script Error: [string "scripts/manager_action_damage.lua"]:517: bad argument #1 to 'insert' (table expected, got nil)

And line 517 is exactly the line of the second table.insert; so, it seems that bDice is again completely erased after the first table.insert. I also tried "d6" or numbers but I always get this error, I do not know why my bDice is always being erased

That's because you're overwriting bDice in the first line with the result of the table.insert function, which I don't think returns anything. This is the first issue you had in your original post - sorry I didn't spot that too, I was more looking at inserting a table into a table being an issue.

Define bDice as an empty table first, then just use table.insert...

Try

Code:

  local dDice = {'d100'};
  table.insert(dDice,'d10');
  Debug.console("some.lua","diceFunction","dDice",dDice);

aaaaaah, okay, now I see it

Oh, I was trying so much and I also found that page from your link but I never saw the difference...

So table.insert is a function returning already the cahnged bDice

For some reasons I thought I have to designate/name that return still for calling it later (therefore the "bDice=..." in front)

Thank you very much

I should have asked earlier, could have saved me a lot of time

Now I wonder how I couldn't see that because table.insert is also used that way in the existing code

Thank you

Yes, that works much better now

If you always want bDice to be a d100 and a d10 then you can just statically set the table as you did in the first line of post #2: local bDice = {"d100", "d10"}; Then you can add any further dice to this as required using one table.insert for each die to be added.
