Snippet Floating Mana Bar

[Sirroelivan]

Here's a very simple trigger to add a floating mana bar above units. It uses only 4 variables, pg(player group), ug (unit group),p (point array) and mana (integer). To change the color of the mana bar change the color code in the bold part. Hope someone finds a use for it.

Mana Trigger
    Events
        Time - Every 0.03 seconds of game time
    Conditions
    Actions
        Set ug = (Units in (Playable map area) matching ((((Matching unit) is alive) Equal to True) and ((Max mana of (Matching unit)) Greater than 0.50)))
        Unit Group - Pick every unit in ug and do (Actions)
            Loop - Actions
                Set String = <Empty String>
                Set Mana = (Integer(((Percentage mana of (Picked unit)) / 2.00)))
                For each (Integer A) from 1 to 50, do (Actions)
                    Loop - Actions
                        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                            If - Conditions
                                Mana Greater than or equal to (Integer A)
                            Then - Actions
                                Set String = (String + |cff0000FF'|r)
                            Else - Actions
                                Set String = (String + ')
                Set p[1] = (Position of (Picked unit))
                Set p[2] = (p[1] offset by (-75.00, 0.00))
                Floating Text - Create floating text that reads String at p[2] with Z offset 210.00, using font size 10.00, color (100.00%, 100.00%, 100.00%), and 0.00% transparency
                Set pg = (All enemies of (Owner of (Picked unit)))
                Floating Text - Hide (Last created floating text) for pg
                Floating Text - Change (Last created floating text): Disable permanence
                Floating Text - Change the lifespan of (Last created floating text) to 0.06 seconds
                Custom script:   call DestroyGroup(udg_ug)
                Custom script:   call DestroyForce(udg_pg)
                Custom script:   call RemoveLocation(udg_p[1])
                Custom script:   call RemoveLocation(udg_p[2])

Code tags?

And you've got a leak here

Set p = ((Position of (Picked unit)) offset by (-75.00, 0.00))

There's 2 locations involved there (Position of (Picked Unit) and the resulting offset point) so you need 2 variables (or an arrayed variable, doesn't really matter) to deal with it properly

Still leaking :\

                Set p[1] = ((Position of (Picked unit))
                Set p[2] = ([B](Position of (Picked unit))[/B] offset by (-75.00,0.00))

Change bolded to p[1]

                Custom script:   call DestroyGroup(udg_ug)

The group should be destroyed OUTSIDE the Unit Group loop (or else you're destroying it once for every unit in the group, even though it was only created once)

@Exide: It's MUI, but it's not very selective in what it allows

 

[Exide]

It's a nice idea.
You should make it MUI, though. And most importantly: Show screenshots!

 

[Sirroelivan]

I've added a screenshot. Also, I believe it's MUI now, or isn't it?

 

[Exide]

Cool. Yea, it looks MUI enough to me. My bad.
+rep. :thup:

EDIT:
You should add a bar, above the mana bar, for the HP. =)

 

[PureOwnage]

Hm.. You should make the bar blue instead of brown
Anyways: :thup:

 

[Infinitegde]

Very nice, looks smooth, MUI, what more could you want?
To change the color all you have to do is change:

Set String = (String + |cff995500'|r)

Change the color code to whatever you want

 

[ImmortaL_GoD]

Just wondering what this part of the trigger does exactly (such as the " ' "?

If - Conditions
                                Mana Greater than or equal to (Integer A)
                            Then - Actions
                                Set String = (String + |cff995500'|r)
                            Else - Actions
                                Set String = (String + ')

And also, how would I select the condition to set the variable to 6 specific units exactly (with the is alive and greater than 0.50 conditions as well)?

 

[cleeezzz]

i believe ' is the bar itself.

so the bar your looking at is really

'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

except color coded.

 

[Fluffball]

Wow... very nice system... I believe you can change the life of the floating text and the periodic timer, although it's fine just as it is... I will use this in my map, might make it health though and add fading age (So as you walk, will fade behind you) +rep... Thanks

 

[The Undaddy]

Any chance the mana bar may overlap with the hp bar?

 

[Sirroelivan]

Thx all for the good remarks.

@Undaddy, i'm not sure, but if it overlaps, you can adjust the height of the mana bar by changing the bolded part in this line.

                Floating Text - Create floating text that reads String at p[2] with [B]Z offset 210.00[/B], using font size 10.00, color (100.00%, 100.00%, 100.00%), and 0.00% transparency

@ Immortal_God, as cleezzz said, the ' makes up the actual bar. In order to make it only visible above some units, just set "ug" to whatever you want. Put the units you want to give a mana bar in another unit group, then just check "all units in playable map area matching mana greater than 0.50 and matching unit is alive equal to true and unit is in <your unitgroup> equal to true.

 

[ImmortaL_GoD]

Ok, thanks a lot, I wasn't sure quite how to compress the trigger (so you didn't have to set each and every one alive/greater than .50).

Lol, all it shows is "String" in white above the unit, and it also changed his color from red --> blue, . Any ideas?

 

[Sirroelivan]

"String" is a string variable, not the actual word "string".

 

[ImmortaL_GoD]

Yeah, I thought I did that, second I'll recheck.

EDIT: Oh shit, I see where I messed up, haha. I useds String variable for the first two, then for reason not for the third (floating text) one. Thanks.

Which measurement would you adjust to move the bar left a little? Since I need to center it on a mage type,
smaller unit.

Was that how you were saying to set up the first part to select specific units? Probably not, but that didn't work anyways, not sure how to select and put that condition on ALL of them. =/

5 Stars!
Creative Idea!!

 

[Sirroelivan]

@ immortalGodz, are those mages you want a mana bar to appear above the only mages on the map, if so, just add "unit-type of matching unit equal to mage" only once to the "set unit group" line.

To put it to the left or right, change to x value in "set p[2] is p[1] with offset (-75.00,0.00)

 

[vypur85]

Hmmm... This seems to have been done before but I can't remember (similar to Ace's Hatchery Havoc?). Seems interesting and nice. But provide a map so that we don't have to recreate the trigger ourself just to see the effect.

+R

 

[Sirroelivan]

I've added a demo map. I've also changed the code a bit, now it doens't show the mana bar to enemies of the player. In single player this doens't matter, but in multiplayer, you can use the mana bars to determine the position of your enemy under the fog of war.

Edit: I'm trying to convert it to JASS, so you only have to copy the code then.

Nah, there's 6 different specific mages, I changed it to simply "Unit Comparison", then I tried something else, and forgot to change it back the same way, so sec, trying again.
