TV6.5 Tutorial 8 - A complete landscape.

[Dimple]

 

Well I'm having some problems with eight lines of code in this Tutorial. I've stared the lines and the error occurs in the code between the *  and the (.
I'll post the full code below that.


' Then, we set everything we can for this water.
    *    Land.SetWaterTexture(Globals.GetTex("Water"))
    *    Land.SetWaterEffect(False, 0.5, True, CONST_TV_BLENDEX.TV_BLENDEX_SRCALPHA, CONST_TV_BLENDEX.TV_BLENDEX_INVSRCALPHA, False)
    *    Land.SetWaterTextureScale(5)
      
      ' We set the water height via a variable. We need this variable
      ' to be able to add an extra underwater fog effect later, at the
      ' rendering.
      sngWaterHeight = 100
   *   Land.SetWaterAltitude(sngWaterHeight)
      
      ' And we finish by enabling the water.
   *   Land.SetWaterEnable(True)
      
      ' New : for fun, we will also add some clouds, just over the water
      ' to give a creepy fog effect. Let's start by loading the clouds textures.
        TextureFactory.LoadTexture("..\..\..\..\Media\clouds.dds", "Clouds", CONST_TV_COLORKEY.TV_COLORKEY_BLACK)
      
      ' Then, set the land's clouds.
   *    Land.InitClouds(Globals.GetTex("Clouds"), CONST_TV_CLOUDMODE.TV_CLOUD_MOVE, 500, 1, 1, 2, 2, 1024)
   *    Land.SetCloudVelocity(1, 0.01, 0.01)
      

And this is in the main loop...


'Light.SetSpecularLightning(False)
        *   Scene.SetSpecularLightning(False)

The message exceeds the maximum allowed length (20000 characters). Again!

will try to post code just under this post...... Rats! The codes to long!! Won't allow the post. Sorry!

Hmmm, looks like you're missing the Land = Scene.CreateLandscape(......)

[Dimple]

 

Crap! your right I have a two versions of this going, one started with the 6.2 tutorial and the other (this one) from 6.3 sourcecode.  I have that in the other one and not this one, and I didn't even notice. Duh! Thanks!! I'll see if that fixes it and report my findings in this thread. later....

[Dimple]

 

Nope, it didn't fix it. I tried it with (Land = Scene.CreateLandscape("Landscape")) and with Land = Scene.CreateLandscape("Water").  I have the same errors as before.  Here's some more code to look at:

Does it work when you remove the "Land = New TVLandscape"?

[Dimple]

 Nope, did a build and got the same eight errors.

[Dimple]

Well, I'm still stuck on this one and not happy with myself.  Since I've not been able to post the code in a post because it's too long. I'll post a link to download a text file of it in a zip folder.  Here it is  If you see what I'm missing - same 8 errors as before! Let me know please.

 

[Ghost]

Have a look at this:
http://tv3dsamples.blogspot.com/2008/04/tv-65-vb-net-tutorials.html

Tutorial 8 is working. I just tested it. So all you have to do is compare it to your code and you should find the error in no time

[Dimple]

 

Thank you Ghost. I had forgotten about that set of samples from TV3DSamples. I've been using a 6.2 and a 6.3 version while working on these tutorials. I will read through the code and see if that will help. Thanks again! I think you just got me unstuck.....

[Dimple]

 

Okay some progress, but I seem to have a poor understanding of how to get the water plane to where it should be on the Landscape.  I'll post the code (Below) that I think should be telling it where to go, but isn't placing it on the landscape. As you can see by the above picture.

Code:

Code:

WaterMesh.AddFloor(Globals.GetTex("Water") - 768, 0, (8 * 256) - 768, 8 * 256, sngWaterHeight, 1, 1, False)

That line looks horribly wrong. It shouldn't be too hard to figure out why.

Uhh... Toaster?  What line? What the...  It's visible here in the topic summary!  I'll check it out. Sorry, this post may be not have been necessary.

[pekbo]

i dont seem to have Land = Scene.CreateLandscape(..) in my truevision 6.2 but there is in truevision 6.5. I wanna use my truevision 6.2 however. how is it so?

[Mithrandir_]

In 6.5 you use the Scene object to create instances of other objects (meshes, actors, landscapes, etc...).

In 6.2 I assume it is just Land = new TV_Landscape().
