Chain Lightning and Chain Heal

[Deleted member 49793]

Basicly as the title says im looking for a Chain Lightning and Chain Heal spell

Basicly Chain Lightning...
shoot at target, looks like hmm hit them then bounces to a random target on screen dealing same damage, then to another and another (bounces 4 times)... Cannot bounce more than 3 squares OR through walls etc.

It's fixed script from post above, but it's still not good (no config and player can use spell without target?!):

function onCastSpell(cid, var)
	local creatures, targets = getSpectators(variantToPosition(var), 3, 3), {}
	if creatures ~= nil then
		while #targets < (#creatures > 3 and 3 or #creatures - 1) do
			local target = creatures[math.random(#creatures)]
			if not isInArray(targets, target) and isSightClear(variantToPosition(var), getThingPosition(target)) and cid ~= target then
				table.insert(targets)
			end
		end

		for k, v in ipairs(targets) do
			if k == 1 then
				doSendDistanceShoot(variantToPosition(var), getThingPosition(v), CONST_ANI_ENERGY)
			elseif k < #targets then
				doSendDistanceShoot(getThingPosition(targets[k - 1]), getThingPosition(v), CONST_ANI_ENERGY)
			end

			doTargetCombatHealth(cid, v, COMBAT_ENERGYDAMAGE, -100, -200, CONST_ME_ENERGYHIT)
		end
	end
	return true
end

It isn't working for me. It is returning that 'creatures == nil'

Do you have needtarget="1" in spells.xml?

 

[VirrageS]

Yep (Should I delete this??)

Do you have needtarget="1" in spells.xml?

...
getSpectators(variantToPosition(var), 3, 3)
...

When you use 'needtarget' I think in 'var' is 'uid' of player attacked (of course you must convert var to number - variantToNumber(var)). Am I right?

Then it should be:

function onCastSpell(cid, var)
    local creatures, targets = getSpectators(getThingPosition(variantToNumber(var)), 3, 3), {}
    if creatures ~= nil then
        while #targets < (#creatures > 3 and 3 or #creatures - 1) do
            local target = creatures[math.random(#creatures)]
            if not isInArray(targets, target) and isSightClear(getThingPosition(variantToNumber(var)), getThingPosition(target)) and cid ~= target then
                table.insert(targets)
            end
        end

        for k, v in ipairs(targets) do
            if k == 1 then
                doSendDistanceShoot(getThingPosition(variantToNumber(var)), getThingPosition(v), CONST_ANI_ENERGY)
            elseif k < #targets then
                doSendDistanceShoot(getThingPosition(targets[k - 1]), getThingPosition(v), CONST_ANI_ENERGY)
            end

            doTargetCombatHealth(cid, v, COMBAT_ENERGYDAMAGE, -100, -200, CONST_ME_ENERGYHIT)
        end
    end
    return true
end

EDIT:
@VirrageS
Do not remove 'needtarget'
