Solved spell beam

silveralol · Dec 27, 2016

hello folks I'm trying make a custom spell for a boss ...
the I want that the monster call the spell with delay of 7 seconds to give the damage
but my spell is a "beam" then I want to fix the direction that the spells happen
actually my spell works fine about the damage and the timer but the direction always is in the north
how fix it ?
then, my spells.xml

Code:

<instant name="zacutter beam" words="###418" aggressive="1" direction="1" blockwalls="1" needlearn="1" script="monster/zacutter beam.lua"/>

and the script zacutter beam.lua

Code:

local voc = {1, 2, 3, 4, 5, 6, 7, 8}

    arr = {
    {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0},

                table.insert(creatureTable, v)
                if n == #creatureTable then
                    break
                end
            end
            i = i + 1
            v = getThingfromPos({x=pos.x, y=pos.y, z=pos.z, stackpos=i}).uid
        end
    end
    if #creatureTable ~= nil and #creatureTable > 0 then
        for r = 1, #creatureTable do
            if creatureTable[r] ~= creature then
                local min = 1000

I am not familiar with lua spells at all, but I see that the arr map of the spell effect seem to only be in one direction?

Perhaps change it up depending on Creature:getDirection() ?
Etc use "arrNorth" spell map for the north direction.

What does the values in the arr map represent? Could it be they represent direction already?
Perhaps try this, see what happens:

Code:

 arr = {
    {0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0},
    {4, 4, 4, 4, 4, 4, 0, 2, 2, 2, 2, 2, 2},
    {0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0, 0, 0},
    }

Just do it like this;

Code:

arr = {
    [0] = {
        {0, 0, 0, .....}
    },
    [1] = {
    },
    [2] = {
    },
    [3] = {
    }
}

also, 3 is the creature/player position not 2.

where the index being creature:getdirection().[/code]

I did not tested it but seems that don't work, the 3 is the creature and it will have effect and damage, the 2 is the creature but don't have effect or damage, the 1 is just the area that will have effect and damage...

could you explain better ? or write some exemple, with the line creature:getDirection()

To get fixed direction you need position in variant to be one square ahead of you.
You can save this function in lib and use it when you need:

Code:

function getCasterPosition(position, direction)
    if(direction == NORTH) then
        return {x=position.x, y=position.y-1, z=position.z}
    elseif(direction == EAST) then
        return {x=position.x+1, y=position.y, z=position.z}
    elseif(direction == SOUTH) then
        return {x=position.x, y=position.y+1, z=position.z}
    elseif(direction == WEST) then
        return {x=position.x-1, y=position.y, z=position.z}
    end

    return position
end

and do combat like this:

Code:

combat:execute(creature, positionToVariant(getCasterPosition(creature:getPosition(), creature:getDirection())))

thank you, your original function works with an issue, to all directions was the adverse
north beam to south etc...
then I invert the function

Code:

function getCasterPosition(position, direction)
    if(direction == SOUTH) then
        return {x=position.x, y=position.y-1, z=position.z}
    elseif(direction == WEST) then
        return {x=position.x+1, y=position.y, z=position.z}
    elseif(direction == NORTH) then
        return {x=position.x, y=position.y+1, z=position.z}
    elseif(direction == EAST) then
        return {x=position.x-1, y=position.y, z=position.z}
    end

    return position
end

or you can just do it like this;

Code:

arrSquare = {
   {0, 3, 0},
   {1, 1, 1},
   {1, 1, 1},
   {1, 1, 1},
   {1, 1, 1},
   {1, 1, 1},
   {1, 1, 1},
   {1, 1, 1},
   {1, 1, 1},
   {1, 1, 1},
}

arrDiag = {
   {1, 1, 0, 0, 0, 0, 0, 0, 0},
   {1, 1, 1, 1, 0, 0, 0, 0, 0},
   {0, 1, 1, 1, 0, 0, 0, 0, 0},
   {0, 1, 1, 1, 1, 0, 0, 0, 0},
   {0, 0, 0, 1, 1, 1, 1, 0, 0},
   {0, 0, 0, 0, 1, 1, 1, 0, 0},
   {0, 0, 0, 0, 1, 1, 1, 1, 1},   
   {0, 0, 0, 0, 0, 0, 1, 1, 0},
   {0, 0, 0, 0, 0, 0, 1, 0, 3}
}

Code:

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_DEATH)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_DEATH)
combat:setArea(createCombatArea(arrSquare, arrDiag)

arrdiag isn't exactly like waht u want, but cba to sit and fix it sorry
