Display image depending on the zone

[ZunaSW]

Hello,

I'm now trying some other things, mainly I want to display an image depending on the zone the player is.
My idea is this:
If for example the player is in Eastmarch zone, Image1 will be displayed as a key is pressed. If then the player changes to Stonefalls zone, Image2 will be displayed as the same key is pressed.

I got no problems with the keybindings, but I'm having problems displaying the different images. For now, when I press the key, I get a 1024x1024 blank image, as I stated here:

local wm = GetWindowManager()
local MainImage = wm:CreateTopLevelWindow(nil)
MainImage:SetDimensions(1024,1024)
MainImage:SetAnchor(CENTER,GuiRoot,CENTER,0,0)
MainImage0 = wm:CreateControl(nil, MainImage, CT_TEXTURE)
MainImage0:SetAnchorFill(MainImage)
MainImage0:SetHidden(true)

I got this code from other of my addons, I'm no expert, so that might be wrong :/ But for now, works.

Now I got the keybinding code:

function IM.OnKeyDown()
	MainImage0:SetHidden(false)
end

function IM.OnKeyUp()
	MainImage0:SetHidden(true)
end

That works perfectly.

And here is the code that I think it is wrong, even when I don't get any errors in game:

function IMOnZoneChanged(eventCode, zoneName, subZoneName, newSubzone)
	if zoneName == "Eastmarch" then
		MainImage0:SetTexture("IM/textures/Image1.dds")
	end
	if zoneName == "Stonefalls" then
		MainImage0:SetTexture("IM/textures/Image2.dds")
	end
end

EVENT_MANAGER:RegisterForEvent(IM.name, EVENT_ZONE_CHANGED, IMOnZoneChanged)

For now, as I said, this last part of the code seems to not work, or at least do what I want it to do. I press the key and get a blank image, instead of the images I stated in the last code.

Any ideas on how to make this work? Maybe I'm using the wrong event, I'm not sure, as I said, I'm no expert.

Thank you.

If you added/changed any .dds files while the game was running, you might need to restart the client. It caches textures (and their absence as well).

Hm, nothing, didn't work :c

Must be something from the code.

hmm, the first zone after loading does not trigger a "change".

You could try to call your zone change function like this in EVENT_PLAYER_ACTIVATED:

IMOnZoneChanged(0, GetUnitZone("player"))

Hm, nothing, doesn't seem to work, I'm using this code, might be wrong though:

function IMOnZoneChanged(0, GetUnitZone("player"))
	if zoneName == "Eastmarch" then
		MainImage0:SetTexture("IM/textures/Image1.dds")
	end
	if zoneName == "Stonefalls" then
		MainImage0:SetTexture("IM/textures/Image2.dds")
	end
end

And I'm getting this error:

user:/AddOns/IM/IM.lua:30: <name> or "..." expected near '0

I might have done something wrong with the event. I'm pretty new on this, so I don't really know :S

I was not precise (or lazy?) Calling, not declaring.

local function IMOnZoneChanged(eventCode, zoneName, subZoneName, newSubzone)
    if zoneName == "Eastmarch" then
        MainImage0:SetTexture("IM/textures/Image1.dds")
    end
    if zoneName == "Stonefalls" then
        MainImage0:SetTexture("IM/textures/Image2.dds")
    end
end
 
local function PlayerActivated()
  EVENT_MANAGER:UnregisterForEvent(IM.name, EVENT_PLAYER_ACTIVATED)
  IMOnZoneChanged(0, GetUnitZone("player"))
end
 
EVENT_MANAGER:RegisterForEvent(IM.name, EVENT_ZONE_CHANGED, IMOnZoneChanged)
 
EVENT_MANAGER:RegisterForEvent(IM.name, EVENT_PLAYER_ACTIVATED, PlayerActivated)
