WoWInterface - HereBeDragons libs usage help.

Hi,

I am trying to implement a simple command to put a icon on a map to specific coordinate.

Lua Code:

local ADDON = ...
 
-- some code
 
local hbd  = LibStub:GetLibrary("HereBeDragons-2.0")
local hbdp = LibStub:GetLibrary("HereBeDragons-Pins-2.0")
 
-- some code
 
local point = CreateFrame("Frame", nil, UIParent)
point:SetWidth(12)
point:SetHeight(12)
point:SetBackdrop({bgFile = "Interface\\Addons\\"..ADDON.."\\icon.tga"})
 
SLASH_GMSPEED1 = "/gmpoint"
SlashCmdList["GMSPEED"] = function(args) 
    local x, y = strsplit(" ",SecureCmdOptionParse(args))
    local mapid
 
    if WorldMapFrame:IsShown() then
        mapid = WorldMapFrame:GetMapID()
    else
        mapid = C_Map.GetBestMapForUnit("player")
    end
    
    -- x,y,mapid = hbd:GetPlayerZonePosition()
    
    print("DEBUG:" .. mapid .. ":" .. x .. ":" .. y)
    
    hbdp:RemoveAllMinimapIcons(ADDON)
    hbdp:AddMinimapIconMap(ADDON, point, tonumber(mapid), tonumber(x)/100, tonumber(y)/100, true, true)
 
    hbdp:RemoveAllWorldMapIcons(ADDON)
    hbdp:AddWorldMapIconMap(ADDON, point, tonumber(mapid), tonumber(x)/100, tonumber(y)/100, HBD_PINS_WORLDMAP_SHOW_PARENT )
end

But it doesn't works as expected ...

Some iussue:

1) /gmpoint x y works (big word :) and puts the icon --> "point" on worldmap and minimap .... but

a) it seems to me the icon disappears as soon as I move
b) it is unable to works after the first use :(
c) is there a nice pin icon I can use in wow texture ?

Thanks for any helps.
