[TFS 1.0] Weapon script for checking direction

[whitevo]

This script checks if you are confronting the target (you are looking in the direction where is target creature)
In my server i wanted that you can't shoot projectiles while you are looking away from target or running away.
(makes a bit harder for paladins)

For some this script is a cake, but i struggled with this quite some time and only thanks to Ninja i was able to complete it.

I made this thread so other people will have an example how to call for x and y positions or simply would like to have same script.


this is script.lua
i changed my enchanted spear so this is why i chose these parameters.
If you want to make this a "global script" so it will choose parameters automatically.
I guess you would have to do huge for loop (i didn't feel like it, instead i'm using 10+slightly different scripts for each projectile)

local combat = Combat()
combat:setParameter(COMBAT_PARAM_BLOCKARMOR, 1)
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENCHANTEDSPEAR)
combat:setFormula(COMBAT_FORMULA_SKILL, 1, 1, 1.0, 1)

function

function onUseWeapon(cid, var)
    local player = Player(cid)
    local target = player:getTarget()
    if not target then
        return false
    end

    local targetPos = player:getTarget():getPosition()
    local playerPos = player:getPosition()

    local CreatureXpos = targetPos.x
    local CreatureYpos = targetPos.y
    local PlayerXpos = playerPos.x
    local PlayerYpos = playerPos.y
    local PlayerDir = player:getDirection()
    local shoot = true

    if PlayerDir == 0 then
        if PlayerYpos <= CreatureYpos then
            shoot = false
        end

    elseif PlayerDir == 1 then
        if PlayerXpos >= CreatureXpos then
            shoot = false
        end

    elseif PlayerDir == 2 then
        if PlayerYpos >= CreatureYpos then
            shoot = false
        end

    elseif PlayerDir == 3 then
        if PlayerXpos <= CreatureXpos then
            shoot = false
        end
    end

    if shoot then
        return combat:execute(cid, var)
    end
    return false
end

don't forget to change your weapons.xml file

<distance id="7367" breakchance="0" unproperly="1" level="1" script="script.lua" />
