Can anyone post a quick example of how to load what you create in a xna game. Im a noob yet. when i save the project it creates and _.xml, _color.tga and _height.bmp files. I understand their use, roughly but how do i load them and display in my game1.cs project?

Thanks!

I'll fix the rectangular size problem of the texture, will look at using an inner circle for the height modification and texture painting.

I'm working on an ingame form system right now, and will be integrating it to the editor.

To gib:
Thanks, glad you enjoy it. As for using it in your own game, you will need a couple of things.. the heightmap class, Triangle class, parts of the MathExtra class, the XMLReader class, the Sun (and sunQuad) and Skybox of course, the camera/mousecam... Those are the main classes. The loading function (LoadTerrain) is located in HeightmapSettings.cs.]]> http://www.gameprojects.com/project?id=8fc946fc5f Tue, 03 Jul 2007 21:33:06 +0000 gib Comments http://www.gameprojects.com/project?id=8fc946fc5f
You're really quite talented and I really appreciate that your building this AND the source code to learn off of.

Thanks for letting us know what classes we will need in our game to load the terrain as I was just stepping through the code now and looking at the LoadTerrain fxn trying to get a feel for how this all works.

I looked at Riemers.com on his terrain tuts but he's not covering how to load from an xml file so I did a search on xna terrain editors and boom found your UTUBE vid.

By the way, I thought we couldn't use windows forms in xna?? That's what I read a few months ago on the xna forum, that the xna framework didnt support it but here you are making it happen. I just noticed that it appears you actually wrote this in native C# and referenced in the using area, the xna framework. Is that a secret nobody knows about - that you can write an xna game in native c# like this and not use game studio express? I thought we had to use the latter? Man, this is what I wanted so I could make my windows forms for my game interface as a prototype (for a mmorpg where you have a logon screen, character generation, inventory system, ect).


You da man!

Thanks,
Gib]]> http://www.gameprojects.com/project?id=8fc946fc5f Wed, 04 Jul 2007 16:03:05 +0000 psycadelik Comments http://www.gameprojects.com/project?id=8fc946fc5f
I didn't know it was impossible to use windows forms, I just tried and it worked.. didn't ask myself why. I'm almost done developing my own system anyway, and I'll share that project as well, very soon.

I'm not using native c#, the game class has been renamed to Editor, thats all.

Anyway, thanks again for the comment.]]> http://www.gameprojects.com/project?id=8fc946fc5f Wed, 11 Jul 2007 09:07:34 +0000 gib Comments http://www.gameprojects.com/project?id=8fc946fc5f
device.RenderState.CullMode = CullMode.ClockWise;

This only draws triangles that are visible. Otherwise, your "drawing" the "opposite side" of objects resulting in too much drawing and completely kills the frame rate. I was playing around with this after finding out why you recommend only doing a 64x64 grid but since I want to design a zone for mmo's - and those are huge I needed to find out why. i hanvent fully played with the program yet with this change though i did do a 256x256 project and this seems to work.

Then I'll begin working on using quadtrees, and the tutorial I will base myself on can be viewed here:

http://www.gamedev.net/reference/programming/features/quadtrees/

It makes more sense using quadtrees for a terrain, since octrees are the three-dimensional analog of quadtrees.

I noticed that when using the height modification tools on a map of 256x256 it was deathly slow. Looking at the code I noticed that it was calling UpdateVertices() from MoveVertices(), and the UpdateVerticies was updating every vert of the map. I changed it to update only the ones that have been changed by the tool. I did the same for the SmoothVertices() method. I also removed the call to SetUpIndices() from within UpdateVertices(). This gave a dramatic speed improvement. I didn't see a need to modify or recreate the indices since there aren't new verticies being created/removed. However, since I'm now skipping the call to SetUpIndices(), I need to make a call to SetUpCollision() so the Tri's are updated with the new Vert positions. Anyway, I am now able to use these tools on large maps without the major loss in fps, and thought it might be something you may want to look into. :D]]> http://www.gameprojects.com/project?id=8fc946fc5f Mon, 10 Mar 2008 04:37:42 +0000 psycadelik Comments http://www.gameprojects.com/project?id=8fc946fc5f http://www.gameprojects.com/project?id=8fc946fc5f Mon, 10 Mar 2008 20:53:48 +0000 durg78 Comments http://www.gameprojects.com/project?id=8fc946fc5f http://www.gameprojects.com/project?id=8fc946fc5f Sat, 22 Mar 2008 14:50:58 +0000 gax1488 Comments http://www.gameprojects.com/project?id=8fc946fc5f http://www.gameprojects.com/project?id=8fc946fc5f Wed, 02 Apr 2008 21:08:12 +0000 gib Comments http://www.gameprojects.com/project?id=8fc946fc5f http://www.gameprojects.com/project?id=8fc946fc5f Thu, 03 Apr 2008 08:05:35 +0000 psycadelik Comments http://www.gameprojects.com/project?id=8fc946fc5f http://www.gameprojects.com/project?id=8fc946fc5f Thu, 03 Apr 2008 22:28:21 +0000 gib Comments http://www.gameprojects.com/project?id=8fc946fc5f http://www.gameprojects.com/project?id=8fc946fc5f Tue, 08 Apr 2008 04:40:42 +0000 halloamt Comments http://www.gameprojects.com/project?id=8fc946fc5f String path = Directory.GetParent(filename).ToString() + Path.DirectorySeparatorChar;

I had tried FreeWorld3d editor and in his documentation he said not to forget to "collapse" the terrain layers into 1 before saving your scene. So to me it seemed like a light went on after I weaved my way through your programs code logic last night.

Did I understand correctly? On the XNA forumns, a gent by the name of LordIkon mentioned doing terrain painting ala Reimer's tuts style but then your only limited to 4 textures total for terrain. Doing a "collapse" of the layers (rgba) into a new texture file(bmp, jpg, png) and then reloading after the paint would allow a person to have a real nice looking landscape then right - since you end up back with just 1 layer.

Did you make your HLSL .fx files wth NVIDIA's tool or do you just know that much about how to code in that lang? I love the groundcursor and of course none of the texture terrain painting is possible without it right?

Sorry for the long post. I guess I'd just mainly like to know if what I said is correct so I know I am learning things correctly. I assume I need to spend alot more time in your code and reimers tuts yet though :)

Thanks!

I don't use any shader tools, I'm having problem making most of them work correctly hehe, so I learn by looking at other shaders and tutorials/help files. The groundCursor position is needed obviously, the texture is just a decoration.

Riemers tutorials are very good, I used them alot when I started the editor.

Here's another good page talking about texture blending : http://www.jenkz.org/articles/terraintexture.htm]]> http://www.gameprojects.com/project?id=8fc946fc5f Thu, 15 May 2008 20:12:18 +0000 gib Comments http://www.gameprojects.com/project?id=8fc946fc5f
I've been studying your code(when I get free time now and then) but seem to be struggling in getting a port of your shader and c# code for the ground cursor. I was just wondering if you would ever consider breaking up your project into mini tutorials(ala Reimers) for that groundCursor technique? I hate to ask but I am sure I am not the only one that would appreciate it. :) I realize though that probably would take some time.

Thanks,
