Transparent Roofs for 1 player

Transparent Roofs for 1 player

I need it so that when a unit enters a region, the roof models become transparent (60%) for the owner of the unit only.
I can't JASS at all and i've read the guides and got the JASS editor

Set UnitVertexColor()
GetLocalPlayer()

I've tried, but its not preciest enouth to work. How do you correctly use these JASS functions to get it working? What is the presist way of doing this?

if GetLocalPlayer()==Player(//player index//)then
call SetUnitVertexColor(//unit//,255,255,255,153)
endif

you can try this script but i've never tried it so i dont know whether it works

This is KaTTaNa's FadeUnitVertexColor Jass snippet from this website http://www.wc3sear.ch/index.php?p=JASS&ID=271&sid=ac0c3aa12ec7cf615ccbf98625c538b4. How do you replace parts of it to refer to the units/players? How do I set up the even so that when the unit enters the region, this only applies to one player? is this even applicable?

you should post your trigger events and actions or i cant get the entering unit and its owning player ,which is the local player

the code you posted is made to fade a unit from 1 rgba to another rgba over time in a consistant manner by calling the function FadeUnitVertexColor(u,r1,g1,b1,a1,r2,g2,b2,a2,time)

if u just want the thing to become transparent instantly for a player, the code snippet is of no use to you pretty much

do what cdp726 said, dunno if it'll desync or not

and learn a programming language, its useful

A quick re-writing of my function to work with local players.
I have not tested it, but I think it works.

It is still up to you to detect when a player enters a house, and to find the unit that represents the roof which you want to become transparent.
To make the roof transparent, just do:

// A unit enters the building
local unit roof = (.. get the roof somehow ..)
call FadeUnitVertexColorForPlayer( roof, 1, 1, 1, 1, 1, 1, 1, 0.40, 1.0, GetOwningPlayer( GetEnteringUnit() ) )

// A unit leaves the building
local unit roof = (.. get the roof somehow ..)
call FadeUnitVertexColorForPlayer( roof, 1, 1, 1, 0.40, 1, 1, 1, 1, 1.0, GetOwningPlayer( GetLeavingUnit() ) )

The 0.40 in the script represent 40% opacity = 60% transparency.

I added in the roof name etc: is this right?

50 complie errors :S does this have to separate or what?

No, you must put the code inside the actions function.

function Trig_Untitled_Trigger_001_Actions takes nothing returns nothing
    // A unit enters the building
    local unit roof = gg_unit_hfoo_0000
    call FadeUnitVertexColorForPlayer( roof, 1, 1, 1, 1, 1, 1, 1, 0.40, 1.0, GetOwningPlayer( GetEnteringUnit() ) ) 
endfunction

function InitTrig_Untitled_Trigger_001 takes nothing returns nothing
    set gg_trg_Untitled_Trigger_001 = CreateTrigger( )
    call TriggerRegisterEnterRectSimple( gg_trg_Untitled_Trigger_001, gg_rct_Region_000 )
    call TriggerAddAction( gg_trg_Untitled_Trigger_001, function Trig_Untitled_Trigger_001_Actions )
endfunction

Do the same for the other trigger.

Oh, and one last thing. For all this to work, go into the map header (the topmost item in the trigger editor with the icon of a map).
Copy and paste the Local Handle Variables in there.
Then, below all the code you just pasted, you paste the code I gave you in my previous post.

Fustrating... 70 compile errors.

Sorry if I'm being n00b-like cause i am Jass n00b!
