[CODING HELP] Target all nearby players

[Lingerdinger]

Hello!

I'm still learning how to code and I wanted to make a few custom items.

I was in the process of making a book that when read, will heal all nearby players.

 

But I was wondering, how to find all nearby players and if differentiating players from other entities is possible.

I also have some other minor questions. 

 

Like, what exactly is inst?

What does the block 'if not TheWorld.ismastersim then' do

and finally what does inst.entity:SetPristine() do.

 

I couldn't find the above code in the data folders.

 

Thank you for the help!

 

local assets=

{

    --Asset("ANIM", "anim/bookofhealing.zip"),

    --Asset("ANIM", "anim/swap_bookofhealing.zip"),

 

    Asset("ATLAS", "images/inventoryimages/bookofhealing.xml"),

    Asset("IMAGE", "images/inventoryimages/bookofhealing.tex"),

}

prefabs = 

{

}

local function fn()

local function readhealfn(inst, reader)

reader.components.sanity:DoDelta(-TUNING.SANITY_LARGE)

 

local pt = Vector3(reader.Transform:GetWorldPosition())

 

local range = 50

 

local ents = TheSim:FindEntities(pt.x, pt.y, pt.z, range)

 

for k, v in pairs(ents) do

--something something not sure how to target palyer

end

end

 

return true

end

 

 

    local inst = CreateEntity()

 

    inst.entity:AddTransform()

    inst.entity:AddAnimState()

    inst.entity:AddSoundEmitter()

 

--not sure what this does

    inst.entity:AddNetwork()

 

    MakeInventoryPhysics(inst)

 

    --inst.AnimState:SetBank("books")

    --inst.AnimState:SetBuild("books")

    --inst.AnimState:PlayAnimation(name)

 

--not sure what this does

if not TheWorld.ismastersim then

        return inst

    end

inst.entity:SetPristine()

 

inst:AddComponent("inspectable")

inst:AddComponent("book")

 

inst:AddComponent("inventoryitem")

inst.components.inventoryitem.imagename = "bookofhealing"

    inst.components.inventoryitem.atlasname = "images/inventoryimages/bookofhealing.xml"

 

inst.components.book.onread = readhealfn

 

inst:AddComponent("finiteuses")

inst.components.finiteuses:SetMaxUses(3)

inst.components.finiteuses:SetUses(3)

inst.components.finiteuses:SetOnFinished(inst.Remove)

 

 

 

    return inst

end

return  Prefab("common/inventory/bookofhealing", fn, assets, prefabs)

FindEntities can filter by tags.

The entities must have all the tags in must_tags to be found.

The entities must not have any tags in cant_tags to be found.

The entities must have at least one tag of must_oneoftags to be found.

TheSim:FindEntities(pt.x, pt.y, pt.z, range, must_tags, cant_tags, must_oneoftags)

Players have the tag, "player", so you put in must_tags {"player"}, like:

TheSim:FindEntities(inst:GetPosition(), 40, {"player"}, {"playerghost"})

Then you loop through ents.

 

You can also loop through AllPlayers, like:

for _, v in pairs(AllPlayers) do   if inst:GetDistanceSqToInst(v) < 40 then      Heal() --- v.components.health:DoDelta(10)   endend

Very useful. Thanks!

[DarkXero]

SenL, I was writing the FindEntities off my memory and screwed up the order of the groups of tags.

I edited my message to reflect the correct way.

Thanks Dark! I truly appreciate this!
