Distance and Gearswap question

It is possible in Gearswap to cancel spell abilities and weapon skill based on the range provided in the res files and taking into account the model size of the mob?

something like maybe using windower.ffxi.get_mob_by_target and windower.ffxi.get_spells?

Never used predefined ranges cause they usually mess with the model size of the mobs.

Thank you.

Yeah, it's possible, but the values as they are in the resources are incomplete. The (approximate) formula for calculating the actual range is this:

distance = target.model_size + spell.range * range_mult[spell.range]

Here range_mult is a table that contains multipliers. Each range has a different multiplier it uses. Here's a list of what I have compiled:

range_mult = {
      [2] =  1.70,
      [3] = 1.490909,
      [4] = 1.44,
      [5] = 1.377778,
      [6] = 1.30,
      [7] = 1.20,
      [8] = 1.30,
      [9] = 1.377778,
     [10] = 1.45,
     [11] = 1.490909,
     [12] = 1.70,
}

so it would be

function get_sets()

range_mult ={
      [2]=  1.70,
      [3]=1.490909,
      [4]=1.44,
      [5]=1.377778,
      [6]=1.30,
      [7]=1.20,
      [8]=1.30,
      [9]=1.377778,
     [10]=1.45,
     [11]=1.490909,
     [12]=1.70,
}

....

end

function precast(spell)

if (target.model_size + spell.range * range_mult[spell.range]) < spell.target.distance then
                cancel_spell()
                return

end

....

end

with that code I get the error attempt to index global 'target' (a nil value)

Another question I have, it's possible in gearswap to equip different ws set for magical WS's? or I need to set them individualy?

You need spell.target.model_size, and yes, that works, although I wouldn't put the range_mult table in get_sets, but outside of it.

We don't distinguish between physical and magical WS, so the latter won't work. You need to hard-code whatever you want it to switch on.

I got it working, but had to add range 0 in the range_mult ([0] = 0) or everytime I use a range 0 spell I'll get an error.

For the magical WS I was thinking on something like:

function precast(spell)
	if T{'magicalws1','magicalws2',...):contains(spell) then
		equip(sets.precast.magicalWS)
	end
end

I have been thinking too on how to cancel a ws if you are unable to see the mob, using the player.facing and the spell.target.x, spell.target.y and spell.target.z, but not sure how to do it. Any idea?

First, you should be using S{...} instead of T{...}. Second, you should define that outside of the function somewhere near the top of the file:

magic_ws = S{'Cyclone', 'Sunburst', ...}

Then later use the code like this:

if magic_ws:contains(spell.english) then

As for the angle, I added some functions to the vector library that should make this easier to handle (you'll need to update Windower for this to work):

require('vectors')
 
function precast(spell)
    if spell.target.type == 'MONSTER' then
        local dir = V{spell.target.x, spell.target.y} - V{player.x, player.y}
        local heading = V{}.from_radian(player.facing)
        local angle = V{}.angle(dir, heading):degree():abs()
        if angle > 90 then
            print('Aborting...')
            cancel_spell()
            return
        end
    end
 
   -- Other crap
end

Working really good, just had to add a rule for it to fire only on weapon skills and reduce the angle to 45, thx Arcon!!

this rule not working after september update

if (target.model_size + spell.range * range_mult[spell.range]) < spell.target.distance then
                cancel_spell()
                return

end

its getting it always as true, its maybe a resource thing?

Updated and seems to be solved now

Yeah, model_size was broken this update, but it was fixed earlier, just needed to re-download LuaCore.

local range_mult = {
        [0] = 0,
        [2] = 1.70,
        [3] = 1.490909,
        [4] = 1.44,
        [5] = 1.377778,
        [6] = 1.30,
        [7] = 1.20,
        [8] = 1.30,
        [9] = 1.377778,
        [10] = 1.45,
        [11] = 1.490909,
        [12] = 1.70,
        }
    if (spell.target.model_size + spell.range * range_mult[spell.range]) < spell.target.distance then
        if player.target.type == "MONSTER" then
            add_to_chat(7,"Monster out of range of spell")
        elseif player.target.type == "NPC" then
            add_to_chat(7,"NPC out of range of spell")
        else
            add_to_chat(7,"Player out of range of spell")        
        end
        cancel_spell()
        return
    end
 

(spell.target.distance - spell.target.model_size) / spell.range

i have been testing this for a couple of days and no mater the spell range or mob size i keep getting the same out put

that being
1.642276421172564

so for my calculations i would use
spell.target.model_size + spell.range * 1.642276421172564 == max spell distance

using the same size mob for all posible distances
spell.target.model_size = 0.30000001192093
spell.range = 0 to 12
 

12.30000001192093    max distance = 20.2
11.30000001192093    max distance = 18.55772357882744
10.30000001192093    max distance = 16.91544715765487
9.30000001192093    max distance = 15.27317073648231
8.30000001192093    max distance = 13.63089431530974
7.30000001192093    max distance = 11.98861789413718
6.30000001192093    max distance = 10.34634147296462
5.30000001192093    max distance = 8.704065051792051
4.30000001192093    max distance = 7.061788630619487
3.30000001192093    max distance = 5.419512209446923
2.30000001192093    max distance = 3.777235788274359
1.30000001192093    max distance = 2.134959367101795
0                    max distance = 0
 

Interesting, maybe they changed the range modifiers. What did you test it with?

i tested it with

12 - cure

11 - Monomi: Ichi

10 - Tourbillion

9 - Death Ray

8 - Voracious Trunk

7 - Awful Eye

6 -

5 -

4 - Temporal Shift

3 -

2 - Hydro Shot

1 -

0 - (always self only)

all the others are just guesses based on what the others said

ofcorse i only did spells

the way i tested

target mob or pc /lockon select the spell backup untill i see the targeting change to yellow the move forward till it just turns blue again cast the spell

this is the code i used to get the numbers(in gearswap) and this creates a file with the range_mult table in it

range_mult ={}
range_mult.ability ={}
range_mult.spell ={}
range_mult.ws ={}
function precast(spell)
    if spell.range then
        if windower.wc_match(spell.prefix, '/jobability|/pet') then
            range_mult.ability[spell.range] = (spell.target.distance / (spell.target.model_size + spell.range))
        elseif windower.wc_match(spell.prefix, '/weaponskill') then
            range_mult.ws[spell.range] = (spell.target.distance / (spell.target.model_size + spell.range))
        else
            range_mult.spell[spell.range] = (spell.target.distance / (spell.target.model_size + spell.range))
        end
    end
    file_write()
end
function file_write()
    local file = io.open('c:/distance.lua',"w")
    local info = {}
    save('range_mult', range_mult)
    file:close()
end
function basicSerialize (o)
    if type(o) == "number" or type(o) == "boolean" then
        return tostring(o)
    else   -- assume it is a string
        return string.format("%q", o)
    end
end
function save (name, value, saved)
    saved = saved or {}       -- initial value
    file:write(name, " = ")
    if type(value) == "number" or type(value) == "string" or type(value) == "boolean" then
        file:write(basicSerialize(value), "\n")
    elseif type(value) == "table" then
        if saved[value] then    -- value already saved?
            file:write(saved[value], "\n")  -- use its previous name
        else
            saved[value] = name   -- save name for next time
            file:write("{}\n")     -- create a new table
            for k,v in pairs(value) do      -- save its fields
                local fieldname = string.format("%s[%s]", name,
                basicSerialize(k))
                save(fieldname, v, saved)
            end
        end
    else
        error("cannot save a " .. type(value))
    end
end
 

i also modified the distance addon to show more them one decimal place

i.e. like this

_addon.name = 'Distance'
_addon.author = 'Windower'
_addon.version = '1.0.0.1'
_addon.command = 'distance'

config = require('config')
texts = require('texts')

defaults = {}
defaults.pos = {}
defaults.pos.x = -178
defaults.pos.y = 21
defaults.text = {}
defaults.text.font = 'Arial'
defaults.text.size = 14
defaults.flags = {}
defaults.flags.right = true

show_full = false
settings = config.load(defaults)
distance = texts.new(settings)

debug.setmetatable(nil, {__index = {}, __call = functions.empty})

windower.register_event('prerender', function()
    local t = windower.ffxi.get_mob_by_index(windower.ffxi.get_player().target_index or 0)
    if show_full then
        distance:text(t.distance:sqrt() or 0)
    else
        distance:text('%.1f':format(t.distance:sqrt() or 0))
    end
    distance:visible(t ~= nil)
end)

windower.register_event('addon command', function(command)
    if command == 'save' then
        config.save(settings, 'all')
    end
    if command == 'show_full' then
        show_full = not show_full
    end
end)
 

then i could put in the command

distance show_full and have it show all the decimals
