help with images

[darksole]

i am working on a addon for my guild, and have 4 images all are 256x256 tga files, i want to make them all pop on the screen in different spots when a mob dies for a set amount of time, i was looking at the Surprise addon witch does sort of the same thing with a image of the word congratulations, but i am lost as to how to accomplish this with the 4 images i have, do i need 4 different frames? or can they be the same frame? was using KillingBlow enhanced as a reference as well but it only pops up 1 image and it changes depending on faction were mine would be the same for every one. any help would be great thanks.

I'm almost certain that there should be no problem creating several textures on one frame.
I suppose you'd want a big invisible frame on the whole screen, with 4 textures somewhere on top of it.
Simply create a texture like this:

myFrame.tex1 = myFrame:CreateTexture ("Texture")
myFrame.tex1:SetTexture ("Interface\\Addons\\Surprise\\surprise1")

And then you can position the texture with SetPoint.

(Yay, someone likes my Surprise add-on!)

If you're only ever going to be showing one of the textures at a time, then you only need one texture object, and you can just change which texture it's displaying:

-- create the parent frame once:
local frame = CreateFrame("Frame", "MyAddon", UIParent)
frame:SetPoint("BOTTOM", UIParent, "CENTER", 0, 100)
frame:SetSize(256, 256)
frame:Hide()

-- create the texture object once:
local tex = frame:CreateTexture(nil, "ARTWORK")
tex:SetAllPoints(true)
frame.texture = tex

-- when you want to show a specific texture:
frame.texture:SetTexture("Interface\\AddOns\\MyAddon\\textures\\blabla")
frame:Show()

For the sake of not cluttering up framestacks, you should set the size and position of your frame, and have your texture inherit from that, rather than setting the frame to cover the whole screen and only positioning the texture.

If you had, say, 4 textures, and you only needed to show one at a time, something like this should work (taking from Phanx's lead).

** Edit: that is some wonky indentation, forum gods!

-- when you want to show a specific texture:
-- your textures are named "blabla1.tga", "blabla2.tga", etc
local counter
frame:SetScript("OnUpdate", function(self, elapsed)
	for i = 1, 4 do
		counter = counter + elapsed -- WoW increments in 0.1 seconds
		frame.texture:SetTexture("Interface\\AddOns\\MyAddon\\textures\\blabla"..i)
		frame:Show()
		if counter == 2 then
			-- hide this frame at two seconds
			frame:Hide()
		end
		counter = 0
	end
end)

You do realize that onupdate time is variable (as in: relative to FPS) right? :P Counter can also be a floating point variable, so using greater than is better to prevent endless loops.

Here's some code to show an animation with a predefined duration:

local name, ns = ...
 
-- texture path. textures are in the addon folder as texture1.tga, texture2.tga, etcetera.
local path = "Interface\\AddOns\\"..name.."\\texture"
-- maxtime is the number of seconds the animation is allowed to run.
local maxtime = 2
-- running is the number of seconds since the animation was started.
local running = 0
-- the number of textures the animation consists of.
local numtextures = 4
-- the number of times the animation must run in *maxtime* seconds.
local times = 4
-- interval is the number of seconds between each texture change. If the entire animation is to run 4 times in 2 seconds, and the animation consists of 4 individual textures, then 2 / 4 / 4 = 0.125 seconds per texture:
local interval = maxtime / times / numframes
-- currenttexture is the currently active texture.
local currenttexture = 1
-- step holds the elapsed time between each texture change.
local step = 0
local frame = CreateFrame("Frame")
frame:Hide()
frame:SetSize(256,256)
frame.texture = frame:CreateTexture()
frame.texture:SetAllPoints()
frame:SetScript("OnUpdate", function(self, elapsed)
    running = running + elapsed
    step = step + elapsed
    if running > maxtime then
        return self:Hide()
    end
    if step < interval then
        return
    end
    step = 0
    currenttexture = currenttexture + 1
    if currenttexture > numtextures then
        currenttexture = 1
    end
    self.texture:SetTexture(path..currenttexture)
end)
frame:SetScript("OnShow", function(self)
    running = 0
    step = 0
    currenttexture = 1
    self.texture:SetTexture(path..1)
end)

This code is not tested but should probably work

Offcourse, this is even easier if you just use 1 texture, then you can just use the animation system.

EDIT: Is OP asking for an animation like this or is he asking for something like bloodsplatters on screen? I remember Resike coding something shiny for that to replace BloodyScreen.
