How do custom dice?

[Munacra]

So I'm trying to implement a Descent: Journeys into the Dark ruleset into FG. It is a boardgame, so it requires some funky looking dice:

Basically, it is a D6, but the faces are custom. On a result of a 2, the meaning is 2 damage, 1 range, for example. The values also change depending on the die color, so essentially you have a green d6 and a red d6, and they are not the same die.

Is there a way to get those dice to work inside FG? I was thinking of just rolling d6's and then just cross referencing them by hand, but I figured that would quickly get tedious. I'd like FG to roll the dice and calculate the results. (throw red 2d6 and yellow d6, script crossreferences it to a table and gives me the result = 8 damage, 3 range, 2 surges) I'm assuming a LUA script would work, but if anyone could give me a tip on where/how to start, that would be super.

[Valarian]

I think you're right that it'll need Lua scripting ... it goes beyond what a simple custom die will be able to produce. I don't think you'll be able to get the pictorial representation in FGII.

I'll try and describe what I think may be needed:
1. Create custom dice based on the d6 model for the different colours (e.g. dR = Red die, dY = Yellow die)
Example: https://www.fantasygrounds.com/forum...1&postcount=14
2. Create custom onDiceLanded() handler for the custom dice in the chat_chat.lua file.
e.g. if "dR" then .... do red die stuff

The custom dice would allow you to use the /die command to roll the dice (e.g. /die 2dR+1dY). The onDiceLanded function in the chat window would then produce the expected results based on the die results.

Such good fun playing this game, took me back to playing Heroquest as a kid ....I can't help but best of luck.

[Munacra]

Thanks. Let me cook up something and I'll update when I get stuck.

[Munacra]

Ok, so the easy stuff is done.

	<customdie name="dR">
		<model>d6</model>
		<menuicon>customdice</menuicon>
	</customdie>
	
	<customdie name="dB">
		<model>d6</model>
		<menuicon>customdice</menuicon>
	</customdie>
	
	<customdie name="dW">
		<model>d6</model>
		<menuicon>customdice</menuicon>
	</customdie>

That makes the custom dice. Now the hard part, I think.

So this is kind of what I want to achieve. In a 1dR, the result of 1 will be 4damage/0range/0surges. On a result of a 2, the dRwill be 1 damage/1 range/1 surge. Etcetera.

so I think that will require a table some pattern matching.

string.gsub (s, pattern, repl [, n])
Returns a copy of s in which all (or the first n, if given) occurrences of the pattern have been replaced by a replacement string specified by repl, which may be a string, a table, or a function. gsub also returns, as its second value, the total number of matches that occurred.

If repl is a string, then its value is used for replacement. The character % works as an escape character: any sequence in repl of the form %n, with n between 1 and 9, stands for the value of the n-th captured substring (see below). The sequence %0 stands for the whole match. The sequence %% stands for a single %.

If repl is a table, then the table is queried for every match, using the first capture as the key; if the pattern specifies no captures, then the whole match is used as the key.

If repl is a function, then this function is called every time a match occurs, with all captured substrings passed as arguments, in order; if the pattern specifies no captures, then the whole match is passed as a sole argument.

If the value returned by the table query or by the function call is a string or a number, then it is used as the replacement string; otherwise, if it is false or nil, then there is no replacement (that is, the original match is kept in the string).

Here are some examples:

x = string.gsub("hello world", "(%w+)", "%1 %1")
--> x="hello hello world world"

x = string.gsub("hello world", "%w+", "%0 %0", 1)
--> x="hello hello world"

x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
--> x="world hello Lua from"

x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
--> x="home = /home/roberto, user = roberto"

x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
return loadstring(s)()
end)
--> x="4+5 = 9"

local t = {name="lua", version="5.1"}
x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)
--> x="lua-5.1.tar.gz"

So since a table is/can be an array, then could I do this?

d6=a/b/c/d/e/f

var dRdamage = new Array(4,0,1,2,3,3)
var dRrange = new Array(0,0,1,0,1,0)
var dRsurge = new Array(0,0,2,2,1,1)
var dRmiss = new Array(0,1,0,0,0,0)

Call up the results and then add them together? Is that possible to do?

Also, the 3d representation of the dice can't be done, but what about the icons in the chatbox? Can the dR die be red and show 3d/4r/0s and the blue die show 2d/1r/3/s?

[Munacra]

oh hey I CAN do it. I'll be back with the actual code isntead of copy-pasting from that java thing.

[Valarian]

I'm afraid I'm not too up on the tables and how they work on lookups. You might be able to get it working. The longhand version would be to interrogate the dice as you go through the onDiceLanded() function

        for i = 1, draginfo.getSlotCount() do
            draginfo.setSlot(i);
            
            local entry = {};
            entry.text = draginfo.getDescription();
            entry.font = "systemfont";
            entry.dice = {};
            entry.diemodifier = draginfo.getNumberData();
            local dicetable = draginfo.getDieList();

            local damage = 0;
            local range = 0;
            local surge = 0;
            local miss = 0;
            
            if dicetable then
                for n = 1, table.maxn(dicetable) do
                    if dicetable[n].type == "dR" then
                        if dicetable[n].result == 1 then
                            damage = damage + 4;
                        elseif dicetable[n].result == 2 then
                            miss = miss + 1;
                        elseif dicetable[n].result == 3 then
                            damage = damage + 1;
                            range = range + 1;
                            surge = surge + 1;
                        elseif ....
                    elseif dicetable[n].type == "dB" then
                        ....
                    elseif dicetable[n].type == "dW" then
                        ....
                    else
                        table.insert(entry.dice, dicetable[n]);
                    end
                end
            end

            if miss > 0 then
                entry.text = entry.text .. " {MISS} ";
            elseif damage > 0 or range > 0 or surge = 0 then 
                entry.text = entry.text .. " {Damage: " .. damage .. ", Range: " .. range .. ", Surge: " .. surge .. "} ";
            end
            
            if User.isHost() then
                if ChatManager.getDieRevealFlag() then
                   entry.dicesecret = false;
                end
                entry.sender = GmIdentityManager.getCurrent();
            else
                entry.sender = User.getIdentityLabel();
            end
             
            deliverMessage(entry);

Thank you Valarian. I think I'm making progress.

[Foen]

For notational/programming convenience, you could try the following:

  local dRresults = {
    damage={4,0,1,2,3,3},
    range={0,0,1,0,1,0},
    surge={0,0,2,2,1,1},
    miss={0,1,0,0,0,0}};

Then to decode a roll of n (between 1 and 6), you would use:

  damage=dRresults.damage[n];
  range=dRresults.range[n];
  surge=dRresults.surge[n];
  miss=dRresults.miss[n];

Hope that helps,

Foen

[Munacra]

That helps a lot because I scoured the internet and read the lua manual over and over again but couldn't get the table to work. Thank you.

Here is what I have so far

function onDiceLanded()
	for i=1, draginfo.getSlotCount() do
	draginfo.setSlot(i);
	
		localentry = {};
		entry.text = draginfo.getDescription();
		entry.font = "systemfont";
		entry.dice = {};
		entry.diemodifier = draginfo.getNumberData();
		local dicetable = draginfo.getDieList();
	
		local damage = 0;
        local range = 0;
        local surge = 0;
        local miss = 0;
        local damagerange= 0;
        
        local dRresults = {
    	damage={4,0,1,2,3,3},
    	range={0,0,2,2,1,1},
   	 	surge={0,0,1,0,1,0},
    	miss={0,1,0,0,0,0}};
    	
    	localdBresults = {
    	damage={1,0,1,2,0,2},
    	range={3,0,3,1,4,2},
    	surge={1,0,1,0,1,0},
    	miss{0,1,0,0,0,0};
    	
    	localdWresults = {
    	damage={3,0,1,1,3,2},
    	range={1,0,3,3,1,2},
    	surge={1,0,1,1,1,0},
    	miss{0,1,0,0,0,0};
    	
    	localdGresults = {
    	damage={2,2,2,1,3,3},
    	range={0,1,0,1,0,0},
    	surge={1,0,1,0,0,0};
    	
    	localdYresults = {
    	damage={1,0,1,0,0,0},
    	range={1,3,2,3,2,2},
    	surge={0,0,0,0,1,1};
    	
    	localdBlackresults = {
    	damagerange={1,1,1,0,0,0},
    	surge=0,0,0,1,1,0{};
    	
    	localdSilverresults = {
    	damagerange={2,2,2,0,0,0},
    	surge={0,0,0,2,2,0};
    	
    	localdGoldresults = {
    	damagerange={3,3,3,0,0,0},
    	surge={0,0,0,3,3,0};

I think Valarian's suggetion would work like this

if dicetable then
                for n = 1, table.maxn(dicetable) do
                    if dicetable[n].type == "dR" then
                        damage=dRresults.damage[n];
                        range=dRresults.range[n];
                        surge=dRresults.surge[n];
                        miss=dRresults.miss[n];

If I can get that to work, that's each individual result. How do I add all the different dice up at the end?
