Revealing map around an item when spawning it ?

[Lumina]

Hi,

I have a treasure map creating a treasure spot when i read it. I would like the treasure spot to be revealed on the map when created : i tried to use the function of the different moonlens, but it's not working as i wish (you need to discover the spot of the map before).

Any clue about how to do this ?

Thanks a lot.

When you share a map with somebody else, it discovers what you have explored for the other person even if that person did not go there at the first place no? I guess that's from where I would start.

It seems to use the maprecorder component.

But i'm not sure i can use it to record only a small part of the map (around the spawned item) and make the user of the treasure map learn it, because i'm not sure the item could "have" a map.

Not sure also this code could help to learn small part of the map, but i must admit it's not a code i understand well.

local pt = Vector3(inst.Transform:GetWorldPosition())
for k,v in ipairs(AllPlayers) do
	if v.player_classified~=nil and v.player_classified.MapExplorer~=nil then
		v.player_classified.MapExplorer:RevealArea(pt.x,0,pt.z)
	end
end

Haven't tested if it works, but you'll get the idea

Can someone explain me what "Vector3" is for? I see it like in lots of scripts, but I can't understand what it's for. I usually use

local x,y,z = inst.Trasnform:GetWorldPosition()

I've made my own treasure mod, and I used maprevaelable components. But It shows icon to every player.

local function SpawnChest(inst)
	local chest = SpawnPrefab("treasurechest")
	local fx = SpawnPrefab("maxwell_smoke")
	
	if chest ~= nil then
		chest:AddComponent("scenariorunner")
		chest.components.scenariorunner:SetScript("chest_treasures")
		chest.components.scenariorunner:Run()
		
		chest:AddComponent("timer")
		chest.components.timer:StartTimer("RemoveChest", TUNING.WHEN_REMOVE_CHEST*.5)
		
		chest:ListenForEvent("timerdone",function(inst)
			local oldonfinish = inst.components.workable.onfinish
			oldonfinish(inst)
		end)
		
		chest.Transform:SetPosition(inst.Transform:GetWorldPosition())
	end
	
	if fx ~= nil then
		fx.Transform:SetPosition(inst.Transform:GetWorldPosition())
	end
	
	inst:PushEvent("RemoveSpot")
end

local function OnDig(inst)
	local fx = SpawnPrefab("groundpound_fx")
	
	if fx ~= nil then
		fx.Transform:SetPosition(inst.Transform:GetWorldPosition())
		fx.Transform:SetScale(.65, .65, .65)
	end
end

local function init(inst)
    if inst.icon == nil then
        inst.icon = SpawnPrefab("globalmapicon")
        --inst.icon.MiniMapEntity:SetIsFogRevealer(true)
        inst.icon:TrackEntity(inst)
    end
end

local function treaure_spot()
	local inst = CreateEntity()

	inst.entity:AddTransform()
	inst.entity:AddAnimState()
	inst.entity:AddSoundEmitter()
	inst.entity:AddMiniMapEntity()
	inst.entity:AddNetwork()

	inst.MiniMapEntity:SetIcon("treasure_cross.tex")
    inst.MiniMapEntity:SetCanUseCache(false)
    inst.MiniMapEntity:SetDrawOverFogOfWar(true)
	
	inst:AddTag("structure")
	inst:AddTag("maprevealer")

	inst.AnimState:SetBank("x_marks_spot")
	inst.AnimState:SetBuild("x_marks_spot")
	inst.AnimState:PlayAnimation("anim")
	
	inst.AnimState:SetLayer(LAYER_BACKGROUND)
	inst.AnimState:SetSortOrder(3)

	inst.entity:SetPristine()

	if not TheWorld.ismastersim then
		return inst
	end

	inst:AddComponent("inspectable")
	
	inst:AddComponent("workable")
	inst.components.workable:SetWorkAction(ACTIONS.DIG)
	inst.components.workable:SetWorkLeft(5)
	inst.components.workable:SetOnFinishCallback(SpawnChest)
	inst.components.workable:SetOnWorkCallback(OnDig)
	
	inst:DoTaskInTime(0, init)

	inst:ListenForEvent("RemoveSpot", function(inst)
		inst:Remove()
		if inst.icon ~= nil then
			inst.icon:Remove()
			inst.icon = nil
		end
	end)
	
	inst:ListenForEvent("timerdone", function(inst, data)
		if data and data.name == "RemoveSpot" then
			inst:Remove()
			if inst.icon ~= nil then
				inst.icon:Remove()
				inst.icon = nil
			end
		end
	end)

	return inst
end

Ah thanks, it's an option, too. Especially if i don't understand how to make JohnWatson code work.

Thanks JohnWatson too, i'll try it.

Vector3 is a mathematical vector. It has coordinates (x, y, z) and some other methods (like getting the magnitude) which makes it easier to use than raw x, y and z values
