[Mod] Always Visible Health Mana XP Text

June 7, 2011 7:14 PM from

Background

We’ve been using the original Always visible health and mana text mod by gunblob (http://forums.demigodthegame.com/369556) for quite some time as part of the advanced ui mod. I recently noticed that the original version has a minor bug that causes some issues with the visual display during replays. Thanks to the assistance of miriyaka, a fix has been found for this issue. I also came up with a new enhancement today that enables you to see your current experience without mousing over the xp bar. You only need to download the version I’m linking to here in this thread if you do not use the advanced ui mod. I will be updating the advanced ui mod and the combined mod installer to include this updated code. This page is only for reference. Do not use this mod AND the enhanced UI mod.

What’s it look like?

What’s the point of the mod?

The purpose of this mod is to alter the UI so that you will always see a text value indicating the exact value of HP and mana of the Demigod you control. Without the mod, you can still view the text values, but you have to move your mouse over the hp and mana bars to view this. With this mod, it is always on.

Why make a mod?

It’s a logical addition that improves the Demigod UI.

How do I use the mod?

Download the mod and run the installer. Then, use the Demigod Mod manager to enable the mod. As this is a UI mod, all players DO NOT need to have this mod installed for you to use it.

Where can I download the mod?

So, I've been working on an update to this that follows similar logic. It's coded and tested and works great, but I'd like a code review from one of you folks so that I can remove additional lines of code that are unnecessary.

Here's what the addition to the mod will do: it will now show your current level and experience to next level (0/200 for instance). This functionality existed previously but was only visible if you moused over it. After the change, you automatically always see your current level and experience to next level.

I also noticed that there is quite a bit of real estate on this bar that additional data could be added to.

To make the mod, I simply copied the entirety of HUD_xp.lua and edited from there. I commented out the mouse over functionality, changed the positioning of the EXP to next level, and changed the functionality so that all would appear. That said, I'm pretty sure I don't need all of the code and would like some help to know what I can remove without doing trial and error. Thanks!

Code: c++

Oh - and on another note, I think I've magically figured out enough about the ui to be able to make a ui mod that would show all of the new stats enabled via uberfix. Not that I'm exactly in a rush, but I did some toying around today with some of the other built in ui menus and I think I could pull this off.

If you want help learning to write hooked / non-destructive code, or help hooking any individual files or functions, I'll be glad to assist with that - but I don't have any interest in digging through entire files to find changes. At the very least, always leave tagged comments next to all of your changes, so that it's easy to find them (e.g. --pacov: etc etc).

Since I know what to look for in this particular instance, I'll write a hook for it for demonstration purposes, but in the future I'd highly recommend starting with a blank file and learning to do proper hooks - it's actually pretty simple, and it makes troubleshooting and debugging a lot easier (especially for people trying to help you):

Code: c++
--save a local copy of the original OnHeroChange
local prevOnHeroChange = OnHeroChange
--re-define the function
function OnHeroChange(unit)
    --call the saved instance
    prevOnHeroChange(unit)
    --make sure the saved instance set the &#39;hero&#39; variable
    --that is declared at the top of the original file
    --if it&#39;s nil, that means we&#39;re in observer mode
    --we could also check &#39;unit&#39;, as that&#39;s what the original
    --sets &#39;hero&#39; to, I&#39;m just mimicking the check that
    --the original does in case I missed something
    if hero then
        --these will have all been hidden by the original
        --instance of the function that we just ran, but
        --we can just Show() them afterward without any
        --visual disruption
        xpTxt:Show()
        xptolevelTxt:Show()
    else
        --if no hero, then insure that the bar is hidden
        bar:Hide()
    end
end
local prevCreate = Create
function Create(parent)
    --call saved, storing what it returns in a local
    local xpBarImg = prevCreate(parent) 
    --change the position of the controls the original function created
    --in this particular case, their reference variables are defined
    --at the top of the file, so we don&#39;t need to reference them
    --within the table/control that the saved function returns
    LayoutHelpers.AtLeftIn(xptolevelTxt, bar, 76)
    
    --un-do the Hide() that the bar&#39;s HandleEvent does on mouseover
    --first we need to save a copy of the original HandleEvent so that
    --other mods&#39; hooks of this function are preserved
    --we could just nil this function out - the whole dummy object,
    --in fact - but then if another mod attempted to hook it, it would
    --generate an error and/or not work at all, so we need to play nice
    local prevHandleEvent = bar.dummy.HandleEvent
    --redefine it
    bar.dummy.HandleEvent = function(self, event)
        --call the saved copy
        prevHandleEvent(self, event)
        --counteract the appropriate Hide() on mouse enter/exit
        if event == &#39;MouseEnter&#39; then
            xpTxt:Show()
        elseif event == &#39;MouseExit&#39; then
            xptolevelTxt:Show()
        end
    end
    
    --return stored local, i.e. what the original function returned
    --this must be done, because the UI function that calls Create
    --uses the control object it returns
    return xpBarImg
end

Hopefully you can figure out what is being done and why from the comments. I'd highly recommend downloading an editor like Notepad++ that does lua syntax highlighting, if you don't already have one. It makes the comments more obvious and readable, if nothing else.

Take a stab at doing your next hook from a blank file, and post if you need help with anything. Most of the UI isn't too difficult to hook, and changing the layout is usually just a matter of hooking a file's Create and adjusting positions etc after running the original function.

Good tips - I'll be sure to leave comments going forward. I'll dig into this sometime tomorrow. Thanks for taking the time, miri!

oh - and I only use notepad ++, so I've got that covered at least.

I'll try to sort through what you coded there. I just ran it on the quick and it works great until you mouse over it. Then it reverts to the original behavior.

ah - got it sorted now. I changed...

            elseif event == &#39;MouseExit&#39; then
                xptolevelTxt:Show()

Code: c++
if event.Type == &#39;MouseEnter&#39; then
                xpTxt:Show()
            elseif event.Type == &#39;MouseExit&#39; then
                xptolevelTxt:Show()

Whoops, I missed that. Obviously I typed it out by hand and didn't test it. Sometimes it pays to copy bits and pieces of the original, and reduce it down to what you need, as it eliminates these kinds of errors.

Miri - if you magically find yourself having some free time (and are feeling super helpful), I thought of one more bit of info I'd like to see added after the XP info. I would love to see the total amount of warscore required for the next level. It could be setup exactly like xp (100/1000 to level 2). At least when I think of it, I would probably like it best if it was changed to just show something like this: 1000 WS to level 10 (and just have 1000 drop). That might even be a better way to display the XP info.

I'm finding that I glance down from time to time to check out that XP info, but perhaps if we just showed a decreasing counter, that might be even better. Anyway, if you have chance to check out the WS display, I'd appreciate it. Thanks!

Adding that to the actual scoreboard would probably be easier. Take a look at HUD_scoreboard (and the in-game scoreboard itself), and see if you can find a way to fit in another 5 digits plus parentheses or brackets next to the war score.
