How to detect specific parts around the player?

Hello,

I was wondering what the best way is to detect specific parts around the player using a localscript. I want to use this so multiple buttons, NPC's, events and more are easily intractable.

So far I have tried using the FindPartsInRegion3 And this was the result.

function detectNPC()
    local Point1 = Character.Torso.Position
    Point1 = Point1 - Vector3.new(10,10,10)
    print(Point1)
    local Point2 = Character.Torso.Position
    Point1 = Point2 + Vector3.new(10,10,10)
    print(Point2)
    local Region = Region3.new(Point1,Point2)
for _,Part in pairs(game.Workspace:FindPartsInRegion3(Region,Character,math.huge)) do
  print(Part.Name)
if Part.Name == "NPC" then  
    print("FoundNPC")
    local A = Part
        if A.Parent.Dialogue ~= nil then
            local children = A.Parent.Dialogue:GetChildren()


        end
end
end
end


while true do
    wait(1)
    detectNPC()
    --print("tested")
end

But it detects nothing not the player or any parts around the Character. Also it gives no errors. Now two questions.

First one is this the way I should do this? (Maybe there is a better way then Findparts in Region)

And if this is the way I should do it what am I doing wrong?
