How create FOG?

[FlashMX]

Hello,

How can I produce fog for the whole world?
How can I color the fog?

I need this information for my mini game, will create a underwater world.

I've also been wondering something like this and the search tool doesn't like me sooo...someone please answer this soon =D

Try IVideoDriver::setFog().

Try IVideoDriver::setFog().

Code: Select all

   virtual void setFog (SColor color = SColor(0, 255, 255, 255),  
            bool  linearFog = true,  
            f32  start = 50.0f,  
            f32  end = 100.0f,  
            f32  density = 0.01f,  
            bool  pixelFog = false,  
            bool  rangeFog = false 
            )[pure virtual]

`pure' undeclared (first use this function)

I use dev-cpp I have everything included and I can't figure out how to fix this.

Have the lib linked and everything. (also searched the forums so no flaming on that note either.)

You don't copy and paste that entire code, that is API/documentation and will not compile.

To use fog in your code, you use:

Code: Select all

driver->setFog(SColor(0,255,255,255),true,50.0f,100.0f,0.01f,false,false);

Obviously changing the variables that need to be changed.

The documentation is to note what each parameter is for (fog color, fog start, end, etc.) and what the function may return if not void.

And did you try searching with your eyes open?

The function you want to call is called setFog(). It is an abstract method of the IVideoDriver interface. Being so, you need to call the function on an object of type IVideoDriver.

When you declare or define a function, you tell the compiler the type of each of the parameters. When you invoke a function, you do not specify the type of each of the parameters, you just specify the values.

If you have trouble understanding any of what I've said above, you should go find a basic C/C++ tutorial and learn the language _before_ you continue learning about Irrlicht any further. It will make your life as a programmer much easier.

And just because I know someone else will spoon feed you the answer as soon as I tell you to learn the language, I'm going to save them the time.

Code: Select all

// add camera
smgr->addCameraSceneNodeFPS();

ISceneNode* terrain = smgr->addTerrainSceneNode("media/terrain-heightmap.bmp");
terrain->setMaterialTexture(0, driver->getTexture("media/terrain-texture.jpg"));
terrain->setMaterialFlag(video::EMF_FOG_ENABLE, true);
terrain->setScale(core::vector3df(10, 1, 10));

driver->setFog(video::SColor(32, 160, 192, 212), true, 100.f, 1000.f, .005f, false, true);
driver->setAmbientLight(video::SColorf(.3f, .3f, .3f, 1.f));

Thanks much for the help...and sorry I'm half asleep and I was never any good with that search button

Thanks Vitek! I've been struggling to figure out why my fog won't work and just seen that I've been missing this...

Code: Select all

terrain->setMaterialFlag(video::EMF_FOG_ENABLE, true);

silly silly me....
