[Coding help] Can't use spell on targets

[Zer000]

Greetings, everyone. Would like to have some assistance, please. I have a little problem: i cant use my item, (its supposed to spawn lightning at target location)on target(inst.components.spellcaster.canuseontargets = true), character says: i can't do this.

I can cast spell at point(inst.components.spellcaster.canuseonpoint = true) but then spell doesn't work properly: lightning always hits only caster.

My code is following: 

local function lSpell(target, pos)
                           TheWorld:PushEvent("ms_sendlightningstrike", target:GetPosition())
                    end

 

I tried alternative way:

Spoiler

 

      local ents = TheSim:FindEntities(pos.x, pos.y, pos.z, 10, {"freezable"}, {"player"})
    for k, v in pairs(ents) do
        lightningSpell(inst, v)

local function lightningSpell(inst, target)

--local x, y, z = target:GetPosition()
                local attacker = inst.components.inventoryitem.owner
                                        attacker.AnimState:PlayAnimation("atk_pre")
            attacker.AnimState:PushAnimation("atk", false)
            attacker.SoundEmitter:PlaySound("dontstarve/wilson/attack_whoosh")
    inst:DoTaskInTime(0.2, function() 
        attacker.components.sanity:DoDelta(-TUNING.SANITY_LARGE * 0.9 )
                                        attacker.AnimState:PlayAnimation("atk_pre")
            attacker.AnimState:PushAnimation("atk", false)
            attacker.SoundEmitter:PlaySound("dontstarve/wilson/attack_whoosh")
                    local max_tries = 4
                    for k = 1,max_tries do
                    local player2 = FindClosestPlayerToInst(inst, 10, true)
                        local pos = player2:GetPosition()
                            TheWorld:PushEvent("ms_sendlightningstrike", pos)
                    end
                            if target.prefab == "dragonfly" then
        target.components.health:DoDelta(-70)
    end
            end)

end

 

but then lightning hits every target in range. Any ideas how to make it work?

I believe your issue is this part.

  local ents = TheSim:FindEntities(pos.x, pos.y, pos.z, 10, {"freezable"}, {"player"})
    for k, v in pairs(ents) do
        lightningSpell(inst, v)

Right now what it's doing is saying find all the entities around the player.

For each entity(ents) cast the lightningSpell on them.

I would take a look at a ranged weapon (fire staff, ice staff, dart) to target your enemy instead.

If you're just having the player cast the spell when the player attacks it's much easier.
