Need help with simple function, it wont work.

Because Controls cant removed, i want to reuse them and if need more add them.

This is my function, it dont work, what ever I try.

Code:

function RMM.CreateControl(iY,iX)

        if not RMM.c.map:GetNamedChild("RMM_MAPS_"..iX..iY) then

                RMM.maps[iY][iX] = WINDOW_MANAGER:CreateControl("RMM_MAPS_"..iX..iY, RMM.c.map, CT_TEXTURE)

        end

end

if not RMM.c.map:GetNamedChild("RMM_MAPS_"..iX..iY) <--- everytime true

RMM.c.map is a CT_CONTROLk, wrong type?

I have also tryed:
if not RMM.maps[iY][iX] then <--- everytime false

And a lot other with: ==nil, ~=nil then return ........ :(

Have you tried:

Code:

if not WINDOW_MANAGER:GetControlByName("RMM_MAPS_"..iX..iY) then

I think i have tryed this yesterday without result, but I will try again. Thanks for Reply.

......

if not WINDOW_MANAGER:GetControlByName("RMM_MAPS_"..iX..iY) then <--- function expected instead of nil

Hey, there is a mechanism for this kind of situations. It's called control pool. You take a control from the pool and when it's no longer needed you just put it back to the pool. Here is an example:

Lua Code:

--first you have to have some parent control
local parentControl = WINDOW_MANAGER:CreateTopLevelWindow("MyParentControl")
--[[
here you create the control pool.
- the first argument is a control template which must be defined in XML file
- the second argument is your parent control
- the third argument is just some name you like
--]]
local myControlPool = ZO_ControlPool:New("MyLabelControlTemplate", parentControl, "SomeName")
 
--then when you want to get a control from the pool you just call:
local myControl, controlKey = myControlPool:AcquireObject()
--controlKey is a key that allows you to put the control back to the pool
 
--you can then do whatever you like with the control, for example attach it to your parent control:
myControl:SetAnchor(CENTER, parentControl, CENTER)
 
--when you no longer need the control, just call"
myControlPool:ReleaseObject(controlKey)
--the control will be hidden automatically, then you can just forget about this control
myControl = nil
controlKey = nil

Here an example XML to define you control template:

Code:

<GuiXml>

        <Controls>

                <!-- It's important to set "virtual" attribute to "true" -->

                <Label name="MyLabelControlTemplate" font="ZoFontGame" virtual="true" />

        </Controls>

</GuiXml>

dont know how i can intigrate this in my code... :confused: And I dont use xml...
But thanks, if no one knows how I can check the exist of my texture, I will try.
I think it must be possible, to check whether the texture exist.

Have you redefined WINDOW_MANAGER somewhere? If WINDOW_MANAGER:GetControlByName() doesn't work, neither should WINDOW_MANAGER:CreateControl()

It's weird that this wouldn't work for you-- I use this all the time:

Lua Code:

tlw = WINDOW_MANAGER:GetControlByName("MODUI_TLW")
if(not tlw) then -- GetControlByName() returns nil if Control does not exist
  tlw = WINDOW_MANAGER:CreateControl("MODUI_TLW", GuiRoot, CT_TOPLEVEL)
end

end

Dont think so.

Code:

function RMM.CreateUI()



        --main

        RMM.c = WINDOW_MANAGER:CreateTopLevelWindow("RMM_root")

    RMM.c:SetDimensions(256,256)

    RMM.c:SetAnchor(TOPLEFT,GuiRoot,TOPLEFT,100,100)

    RMM.c:SetHidden(false)

    RMM.c:SetMovable(true)

    RMM.c:SetMouseEnabled(true)

    RMM.c:SetClampedToScreen(true)



--overlay

    RMM.c.overlay = WINDOW_MANAGER:CreateControl("RMM_overlay", RMM.c, CT_TEXTURE)

        RMM.c.overlay:SetTexture("RadarMiniMap/textures/rad.dds")

    RMM.c.overlay:SetAnchorFill(RMM.c)        

        RMM.c.overlay:SetDrawLayer(3)

        

        --nord

        RMM.c.nord = WINDOW_MANAGER:CreateControl("RMM_nord", RMM.c, CT_TEXTURE)

        RMM.c.nord:SetTexture("RadarMiniMap/textures/nor.dds")

    RMM.c.nord:SetAnchorFill(RMM.c)        

        RMM.c.nord:SetDrawLayer(4)

        

    --scroll

    RMM.c.sc = WINDOW_MANAGER:CreateControl("RMM_scroll", RMM.c, CT_SCROLL)

    RMM.c.sc:SetAnchorFill(RMM.c)



    --map

        RMM.c.map = WINDOW_MANAGER:CreateControl("RMM_map", RMM.c, CT_CONTROL)

        RMM.c.map:SetAnchor(TOPLEFT, RMM.c, TOPLEFT, 0,0)

        

end

There is a opposit between our code:

Code:

WINDOW_MANAGER:CreateControl("MODUI_TLW", GuiRoot, CT_TOPLEVEL)



WINDOW_MANAGER:CreateTopLevelWindow("RMM_root")

Is that the problem?
