GUI: dynamically created

Hi @ll,
I am trying to create an inventory with a variable Number of Slots.
So I tried to realize this using the following Code:
Code: Select all
function InitInventorySlots(SlotsCnt, ...)
Inventory.SlotsCnt = SlotsCnt;
end
function Inventory:OnActivate()
local i = 1;
local ItemsPerLine = 5;
Slots = {};
for i = 1, self.SlotsCnt, 1 do
Slots[i] = gui:new("WindowT", "Slot" .. i);
Slots[i]:set("rect", 540 + ((i % ItemsPerLine) * 28), math.floor(i / ItemsPerLine) * 28, 25, 25);
Slots[i]:set("backColor", 0, 0.25, 0.7, 0.4);
Slots[i]:set("borderWidth", 0.5);
Slots[i]:set("borderColor", 0.7, 0.8, 0.9, 1);
Inventory:AddChild(Slots[i]);
end
end
The code used in
Inventory:OnActivate() was in
InitInventorySlots(SlotsCnt, ...) before, but my Inventory shows up without the Items. No error, just does not show up. Do I have to make an init method for every slot? And how can I realize this with dynamically created windows?

Could you please attach the complete *.cgui files for your GUI?
Things are hard to tell from that fragment alone.

For sure I can
Inventory_init.cgui
Code: Select all
InvBg = gui:new("WindowT", "InvBg");
Inventory = gui:new("WindowT", "Inventory");
gui:SetRootWindow(InvBg);
-- Setup the window hierarchy.
-- ***************************
InvBg:AddChild(Inventory);
-- Initialization of the window contents ("constructor code").
-- ***********************************************************
function InvBg:OnInit()
self:set("backColor", 1, 0, 0, 0.7);
gui:activate (false);
gui:setInteractive(true);
gui:showMouse (true);
end
function Inventory:OnInit()
self:set("rect", 400, 100, 100, 300);
self:set("backColor", 0, 0.25, 0.7, 0.4);
self:set("borderWidth", 0.5);
self:set("borderColor", 0.7, 0.8, 0.9, 1);
gui:setFocus(Inventory);
end
and my Inventory.cgui
Code: Select all
dofile("Games/obg/GUIs/Inventory_init.cgui");
function InitInventorySlots(SlotsCnt, ...)
local i = 1;
local ItemsPerLine = 5;
Slots = {};
for i = 1, SlotsCnt, 1 do
Slots[i] = gui:new("WindowT", "Slot" .. i);
Slots[i]:set("rect", 540 + ((i % ItemsPerLine) * 28), math.floor(i / ItemsPerLine) * 28, 25, 25);
Slots[i]:set("backColor", 0, 0.25, 0.7, 0.4);
Slots[i]:set("borderWidth", 0.5);
Slots[i]:set("borderColor", 0.7, 0.8, 0.9, 1);
Inventory:AddChild(Slots[i]);
end
end
function InvBg:OnChar(ch)
if (ch == 0x1B or ch == 0x69) then -- ESC or I
gui:activate(false);
return true;
end
return false;
end

Well, in function
InvBg:OnInit() a line like
Code: Select all
self:set("rect", 0, 0, 640, 480);
is missing if you want it to be visible.
Function
InitInventorySlots() is nowhere called in your code, thus it cannot generate the windows that you expect.
If I copy the contents of
InitInventorySlots() into the
Inventory_init.cgui file and add line
local SlotsCnt = 3; as well, then I see three generated child windows when I load the GUI into the GUI Editor.
Note however that the position of child windows is relative to their parent, so in this case, an x-coordinate of 540 and more is way off screen.
Btw., best you make sure that
InitInventorySlots() is only called once… e.g. just call if from the main body of the script:
Code: Select all
function InitInventorySlots(SlotsCnt, ...)
-- ...
end
InitInventorySlots(3);

AH, oh my god, just found it:
InitInventorySlots() is called on button press from c++, but i did not realize that I need to place the items relatively
Thanks for opening my eyes
