[Solved] White screen problem for some players? Help

[stan0033]

Hi all, I was hosting today my map, and 2 players reported having a completely white screen of the terrain and anything on it, and the second sent me a screenshot. He said he doesnt have this problem with other maps.He also said that his minimap is green when switched on
What might it be? I never before seen such a issue.

Wow I must admit I have never seen this before :O
Only thing I can think of is a corrupted model.

Have you tried to test all your models with @GhostWolf MDX/MDL Sanity tester ?
Just in case, here it is : Mdx sanity tester

 

[stan0033]

The sanity testes tells me that the progress bars don't have stand animation and
for imported tilesets "this mipmap should not exist"
for imported icons "this mipmap is fake"
for the model of the loading screen "Number of sequence extents (0) does not match the number of sequences (1)"

Ok. Well unfortunately these issues are not abnormal, nor does they seem to explain this issue they encountered.
Have you asked the players with this glitch about their systems (Mac, Windows ?).

It seems you didn't get an educated answer besides mine in spite of the views, so it seems it isn't a common problem.

Maybe someone with more experience would have an idea (we never know).
@Dr Super Good : have you ever seen anything like that ?

 

[stan0033]

No, I didn't ask them. I thought about asking them, but since this is an old game, and their PCs 100% support all needed for the game, the problem must be somewhere else I don't know about.

 

[Macadamia]

I was just thinking it might be caused by a system type or setting as not everyone has the issue.

What version of Warcraft III?

This could be a broken model affecting lighting, a screen filter or a graphic driver bug.

 

[stan0033]

1.26а
No screen filters are added.
Could a weather effect do it?

 

[deepstrasz]

What version did they play it on? You made it on 1.26 I understand.
Also, it would be a good idea to link to the map file next time: Gold Diggers Extreme

Thanks to @deepstrasz I could take a look at your map code for myself and noticed that you are using a Terrain Fog function with invalid parameters within CameraZoom init function.

//===========================================================================
function InitTrig_CameraZoom takes nothing returns nothing
    local trigger trig = CreateTrigger()
    local integer i = 0
    loop
        exitwhen i == bj_MAX_PLAYERS
        call TriggerRegisterPlayerChatEvent(trig, Player(i), "-zoom ", false)
        set i = i + 1
    endloop
    call TriggerAddCondition(trig, Condition(function gg_trg_CameraZoom_Conditions))

    call SetTerrainFogExBJ( 0, 10000000.00, 1000000.00, 0.5, 100, 100, 100 )
endfunction

Either remove that line or change its parameters to something different where the second parameter should be smaller than the third one. Like this
call SetTerrainFogExBJ( 0, 19900., 20000., 0.5, 100, 100, 100 ) // Even though this makes no sense lol

 

[Macadamia]

Indeed that seems the be the cause.

Just a note about the parameters :
The maximum farZ distance for the camera is 10,000.0, so no need to use 10,000,000.0 like you did for zstart and zend, it might even cause issues.
First parameter is the style : 0="Linear", 1="exponential 1" and 2 = "exponential 2" IIRC.
The last parameter before the 3 color ones is the density.

You could indeed try to change z values to correct ones, and the density and color depending on what you want to achieve.
You could try 10,000.0 for z or maybe 0 for density if you want fog to disappear when your camera is zoomed out

By the way you could also replace the BJ function by the corresponding native as all it does is change the colors values :

function SetTerrainFogExBJ takes integer style, real zstart, real zend, real density, real red, real green, real blue returns nothing
    call SetTerrainFogEx(style, zstart, zend, density, red * 0.01, green * 0.01, blue * 0.01)
endfunction

I suppose you could use this : SetTerrainFogEx(0, 10000.0, 10000.0, 0, 1.0, 1.0, 1.0), thats what I use in my own map.

Good luck !

Well, the code for the camera isn't made by me, I found in on the Internet but thanks to all for the help! I will go fix it now.

 

[Macadamia]

Good luck, and keep us updated !
