Helperscript for weapon damage.

[Kurald]

Hi,

I created a helper script for rolling damage. It evaluates a damage expression in the weapon list and creates the dice for rolling the damage.

the script is one function:

function onDrag(button, x, y, draginfo)
	local value = getValue(); --get damage value
	value = string.lower(value); --convert to lower case
	--amount: number of dies
	--dietype: type of die
	--modifier: modifier for the die roll
	test,_, amount, dietype, modifier = string.find(value,"(%d+)d(%d*)([+-]?%d*)");
	print(test) --if it matches a fully evaluated damage (e.g. 3d+2) and not sw+1 or thr+1
	if test~=nil then
		if dietype == "" then --set dicetype to d6 if not present (GURPS style)
			dietype = 6;
		end
		if modifier == "" then --set modifier to 0 if not present
			modifier = 0;
		end
		--Debug output - enable if needed
		--print("Amount: "..amount);
		--print("Dietype: "..dietype);
		--print("Modifier: "..modifier);
		local dielist = {} --declare dielist
		for i=1,amount do --fill dielist according to the expression
			dielist[i]="d"..dietype;
		end
		draginfo.setType("dice");
		draginfo.setDieList(dielist);
		draginfo.setNumberData(modifier);
		draginfo.setDescription("damage:");
	else
		print("no constant damage found");
	end
	return true;
end

There's still one problem: I did not figure out yet how I can include the weapon name in the draginfo description

insertion points: charsheet_weapons.xml

• <textlistitemvalue name="handweapon_damage">
• <textlistitemvalue name="rangedweapon_damage">

insert the following tag:
<script file="scripts/onDragParser.lua" />

and save the code above into the file mentioned in the script tag.

Please test it and check if you like it. Of course you may include it into your code base if you like spyke. As far as I see it, it does not automate any GURPS mechanics. It only grabs the dice. It does not calculate the damage if it is stat-based. This way it should comply to the licence.

Please feel free to try it and give feedback.

Hi,

I just added support for the multiplier notation of GURPS (e.g. 6dx3).

Here's the code:

function onDrag(button, x, y, draginfo)

        local name = "";
	-- check weapon name. dependent on Spykers GURPS ruleset
	if window.rangedweapon_name_mode ~= nil then
		name = window.rangedweapon_name_mode.getValue();
	end
	if window.handweapon_name ~= nil then
		name = window.handweapon_name.getValue();
	end

	local value = getValue(); --get damage value
	value = string.lower(value); --convert to lower case
	--amount: number of dies
	--dietype: type of die
	--modifier: modifier for the die roll
	test,_, amount, multiplier = string.find(value,"(%d+)d(x%d+)"); --GURPS 6dx3-like damage notation
	if test~=nil then
		--Debug output - enable if needed
		--print("Amount: "..amount);
		--print("Multiplier: "..multiplier);
		local dielist = {} --declare dielist
		for i=1,amount do --fill dielist according to the expression
			dielist[i]="d6";
		end
		draginfo.setType("dice");
		draginfo.setDieList(dielist);
		draginfo.setNumberData("0");
		draginfo.setDescription(name.." damage, multiply by "..multiplier..":");
	else
		test,_, amount, dietype, modifier = string.find(value,"(%d+)d(%d*)([+-]?%d*)");
		if test~=nil then
			if dietype == "" then --set dicetype to d6 if not present (GURPS style)
				dietype = 6;
			end
			if modifier == "" then --set modifier to 0 if not present
				modifier = 0;
			end
			--Debug output - enable if needed
			--print("Amount: "..amount);
			--print("Dietype: "..dietype);
			--print("Modifier: "..modifier);
			local dielist = {} --declare dielist
			for i=1,amount do --fill dielist according to the expression
				dielist[i]="d"..dietype;
			end
			draginfo.setType("dice");
			draginfo.setDieList(dielist);
			draginfo.setNumberData(modifier);
			draginfo.setDescription(name.." damage:");
		else
		
			print("no constant damage found");
		end
	end
	return true;
end

I had to include and additional regex for that.

Impressive. I'm away travelling at the moment, but I'll take a look next week when I get back.

I'm glad if I can give you something back. The ruleset you created is great.

------------------

Added support for weapon name. Wepon name now displayed on die roll. Code added to the second code window.

[Kurald]

I included handling for swing and thrust damage. The damage entered in the main tab will be read and modified according to the entered damage.

E.g.: main tab: Thrust 1d6-1, Weapon: Katana thrust+1
this information will 'automagically' transformed into 1d6 and the draginfo will be created appropriatly.

Next step: filter the wounding modifier (cr, imp, pi+, ...) and include them in the description posted.
Example: Knife damage (imp): 2+1

function onDrag(button, x, y, draginfo)
	local characterNode = getDatabaseNode().getParent().getParent().getParent(); -- get charsheet db node
	local statsNode = characterNode.getChild("stats"); -- get stats db node
	local thrustNode = statsNode.getChild("thrust"); -- get thrust damage db node
	local swingNode = statsNode.getChild("swing"); -- get swing damage db node
	
	local thrust = thrustNode.getValue(); -- read thrust damage
	if thrust == nil then thrust = "" end
	local swing = swingNode.getValue(); -- read swing damage
	if swing == nil then swing = "" end
	
        local name = "";
	-- check weapon name. dependent on Spykers GURPS ruleset
	if window.rangedweapon_name_mode ~= nil then
		name = window.rangedweapon_name_mode.getValue();
	end
	if window.handweapon_name ~= nil then
		name = window.handweapon_name.getValue();
	end
	
	local value = getValue(); --get damage value
	value = string.lower(value); --convert to lower case
	-- check if swing or thrust damage. if that is the case, replace the damage with die damage and proceed normally
	-- swing
	test,_,summand = string.find(value,"sw([+-]?%d*)");
	if test~=nil then
		--we have swing damage
		--dissect swing damage and add the summand
		test,_, amount, dietype, modifier = string.find(swing,"(%d+)d(%d*)([+-]?%d*)");
		if test == nil then return true; end -- no swing damage entered
		if modifier == "" then --set modifier to 0 if not present
			modifier = 0;
		end
		if summand == "" then
			summand = 0;
		end
		summand = summand + modifier;
		if summand<0 then
			value = amount.."d"..summand;
		else
			value = amount.."d+"..summand;
		end
	end
	test,_,summand = string.find(value,"thr([+-]?%d*)");
	if test~=nil then
		--we have swing damage
		--dissect swing damage and add the summand
		test,_, amount, dietype, modifier = string.find(thrust,"(%d+)d(%d*)([+-]?%d*)");
		if test == nil then return true; end -- no thrust damage entered
		if modifier == "" then --set modifier to 0 if not present
			modifier = 0;
		end
		if summand == "" then
			summand = 0;
		end
		summand = summand + modifier;
		if summand<0 then
			value = amount.."d"..summand;
		else
			value = amount.."d+"..summand;
		end
	end
	
	
	print("Value: "..value);
	--amount: number of dies
	--dietype: type of die
	--modifier: modifier for the die roll
	test,_, amount, multiplier = string.find(value,"(%d+)d(x%d+)"); --GURPS 6dx3-like damage notation
	if test~=nil then
		--Debug output - enable if needed
		--print("Amount: "..amount);
		--print("Multiplier: "..multiplier);
		local dielist = {} --declare dielist
		for i=1,amount do --fill dielist according to the expression
			dielist[i]="d6";
		end
		draginfo.setType("dice");
		draginfo.setDieList(dielist);
		draginfo.setNumberData("0");
		draginfo.setDescription(name.." damage, multiply by "..multiplier..":");
	else
		test,_, amount, dietype, modifier = string.find(value,"(%d+)d(%d*)([+-]?%d*)");
		if test~=nil then
			if dietype == "" then --set dicetype to d6 if not present (GURPS style)
				dietype = 6;
			end
			if modifier == "" then --set modifier to 0 if not present
				modifier = 0;
			end
			--Debug output - enable if needed
			--print("Amount: "..amount);
			--print("Dietype: "..dietype);
			--print("Modifier: "..modifier);
			local dielist = {} --declare dielist
			for i=1,amount do --fill dielist according to the expression
				dielist[i]="d"..dietype;
			end
			draginfo.setType("dice");
			draginfo.setDieList(dielist);
			draginfo.setNumberData(modifier);
			draginfo.setDescription(name.." damage:");
		else
		
			print("no constant damage found");
		end
	end
	return true;
end

I just added drag&drop for personalities as well. It supports (2) different attacks by using different (left / middle) mouse buttons. The damage has to be seperated by ; and it can not contain sw / thr as these are not included in the sheet.

I want to add support for additional weapons using shift/alt/ctrl to distinguish the different weapons, but I don't know if I can get the state of these keys.

----------------------------------------------------------------------------------------------------
I just found the input and changed the coding:

MB1 selects the first damage,
MB1+shift selects the second
MB1+alt selects the third
MB2 selects the 4th
MB2+shift the 5th
MB2+alt the 6th

ctrl reveals the dice (built-in function)

The order is how the keys are arranged on the keyboard (from top left to lower right)

[Kurald]

Next plans: throwing 3d6 on skills & displaying the skill name and level. This way the GM can ask for a skill roll and the player just has to throw the dice via drag and drop. And the GM has all the information needed.

[saithan]

these would really help me gain better control over the flow of my gurps games
can some one please elaborate on getting these scripts functional.

with the first script I created onDragParser.lua placing the code into it

the opened the charsheet_weapons.xml
and added <script file="scripts/onDragParser.lua" /> after each of the two points.
<textlistitemvalue name="handweapon_damage">
<textlistitemvalue name="rangedweapon_damage">
loaded my gurps_4e campaign and see nothing to drag.

does these scripts need a button or such added to the charactersheet to make them function?

thanks in advance.

[Kurald]

no, they work directly. The script parsed the text written as damage and converts it into damage dice.

[saithan]

I must be missing something because I'm not getting any drag-able from the character sheets.
