Using SunBurn

Model Import Problem.

Peter — Mon, 20 May 2013 11:51:33 GMT

I changed some Anomation on my model in Blender and exported to fbx.

After i changed the model with the existing one in my Visual Studio project i won't compile throwing

Split animation Custom_Walk on animation Walk has an end time bigger than the original animation duration.

Can i fix this anyway?

Share what you are working on

Sunburn is awesome. XNA is awesome. Sunburn + XNA makes me wanna program 32 hours a day. Attached is what I am working on, I would love to know how many other projects out there are cooking up something cool in the oven!

Clip, Blend or Alpha for transparency?

Nipun — Mon, 13 May 2013 18:58:44 GMT

I have added some foliage to my game and to cut out parts of the foliage based on alpha Im using "Additive" (since it gives me a much better result compared to clip). Im facing this weird flickering problem though when Im moving around in the map. As I am approach the trees, they start flickers and when I get closer to the tree's the flickering stops. Can some one help me with whats the best way to clip the alpha channel !!!

Thanks...

Character Contoller

Peter — Wed, 15 May 2013 15:34:03 GMT

Hello,

what are the best adjustments for a good moving behaviour?

This are my adjustments

 // Set Character Controller  
                _playerContollerComponent = new CharacterControllerComponent ( );
                _playerContollerComponent.PlayerIndex = PlayerIndex.One;
                _playerContollerComponent.AffectedInCode = true;
                _playerContollerComponent.JumpSpeed = 2.0f;
                _playerContollerComponent.MaximumSpeed = 100.0f;
                _playerContollerComponent.MaximumCrouchSpeed = 50.0f;
                _playerContollerComponent.MaximumSlideSpeed = 0f;
                _playerContollerComponent.MovementSmoothing = 0.1f;
                _playerContollerComponent.MaximumAirborneSpeed = 180;
                _playerContollerComponent.MovementForce = 10000;
                _obj.Components.Add ( _playerContollerComponent );
 
                _controller = ( ICharacterController )_playerContollerComponent.Controller;

And environment Gravity 1000f.

I wan't to avoid the moved player from to much sliding then movement stops.

Out of Topic Blender Question

Peter — Sun, 19 May 2013 11:34:54 GMT

Hi,

i use Blender for rigging and animating Models.

I learned from this excellent tutorial made as several part tutorial on YouTube.

http://www.youtube.com/watch?v=cMMu34fNZdg

Great for Indie developers.

But there are two things that are not ok.

My as FBX file exported model is imported to XNA head down.

And the Animations made with Blender pose libary are running to fast.

Do i have to adjust the different poses in Blender to higher frame distances or are there other properties i have to take a look on?

Are here some Blender specialists?

Fur Shader idea "request"

Ole — Fri, 17 May 2013 10:55:30 GMT

Hi folks,

I'm testing around with shaders and my question is now if someone of you have an idea how to create a mesh fur shader?

My goal is something like this example (googled):

http://www.nickyliu.com/v3/images/temp/furShaderTest.jpg

It would be really nice if you have an idea. :)

The gravity "falling down" simulation is not important for the first steps.

Regards,

Ole.

Bullet Objects

Peter — Mon, 13 May 2013 14:36:26 GMT

I try to create some bullets coresponding to this Tutorial

http://dsebj.evolvingsoftware.com/2011/04/26/object-instancing-weapons-fire-sunburn-component/

But for some reason the CollisionMove object in the bullet Sceneobject is always null.

SceneObject bullet = new SceneObject ( );
                SceneObject copyBase;
                SceneInterface.ActiveSceneInterface.ObjectManager.Find ( "Bullet", true, out copyBase );
                bullet = ( SceneObject )copyBase.Clone ( );
                bullet.CollisionMove.RemoveForces ( ); <= Null Reference Exeption

What i'am doing wrong?

Switched to Game State Management from Indiefreaks

Peter — Fri, 03 May 2013 18:33:25 GMT

Hello,

are there some WP7 tutorials for absolute newbies to Sunburn?

I think about how to beginn a WP7 Sunburn project step by step.

I coded some 2d Games without any Engine in XNA. So i'am not a total noob.

But most of the examples i find in my Indie section won't compile.

So is there a chance to find some good guidance?

The Zoom is the distance the camera is away from the model.

The pitch between 0 and -1 regulates the view angle from 0° (behind my model) to 90° (directly over my model).

Now i get the following result:

The view distance is not in a good range.

How can i adjust the view distance?

I tried to increase Visible distance in environment without success.

ScreenManager.environment.VisibleDistance = 20000f;

Out of Memory Issue

Nipun — Tue, 07 May 2013 07:25:28 GMT

I have run into the dreaded outofmemory issue :( I have multiple scenes in my game and they are heavy scenes. When Im switching between scenes, Im calling the sceneInterface.Clear() and then loading the new scene and submitting it.

sceneInterface.Clear();

scene = Content.Load<

Scene>("Scenes/Scene");

sceneInterface.Submit(scene);

Im using the same scene object for all my scenes. I thought calling Scene.dispose() will solve the issue but im still getting the outofmemory issue at the following line.

scene = Content.Load<Scene>("Scenes/Scene");

Do I need to create separate scene objects ? WHats the issue with using a single scene object even though Im calling Scene.Dispose() before loading the new scene?

Thank you for your reply in advance.

2D Sprites

Is Sunburn Still Active?

bluebooth — Thu, 09 May 2013 22:50:31 GMT

I just bought Sunburn yesterday, hoping to tie in with IGF, to give my indie team a powerful and tested engine. But the visible state of public relations has me worried I may have made a bad purchase.

I've been trying to find information regarding the status of SunBurn 2.1 and also for the SunBurn plugin IGF. IGF looks completely dead - there's been no updates in 8 months, and the samples provided on the codeplex page will not compile. I can't find any form of contact to reach the developer. I suspect IGF is simply too closely tied to XNA to separate from it, but that's still frustrating, because it was for IGF that I purchased SunBurn.

As for SunBurn 2.1, the news indicated that it was close to release, but that was over a month and a half ago. I checked the twitter page mentioned on the site, but that hasn't seen update since October, and the youtube page, which hasn't seen new content in over a year.

Understandably, Microsoft's behavior regarding XNA has thrown a wrench in all our plans. But will SunBurn still be moving forward as it posted, and can we expect to see a revival of community engagement or not?

Thank you, and I hope to hear from you shortly.

Model Animation Newbie

Peter — Tue, 07 May 2013 10:31:02 GMT

Hello i'am totally new to Sunburn,

where to start with model animation in Sunburn Indie?

I have created a 3D model in Blender and added some bone animations.

I exported the model as FBX model. Where can i get information about playing the different animations via sunburn, based on states i add to the model.

Transparency and Specularity of objects

JessMaccy — Sat, 11 May 2013 21:21:36 GMT

I exported a model from Maya into fbx format (checking that embed media is true). I can see that the fbx files have transparency factors and has specular properties.How do I get the specular and transparent materials to render properly?

I'm currently using something like this:

Model model = MyGame.content.Load<Model>("Models/Model1");

SceneObject so = new SceneObject(model);

MyGame.sceneInterface.ObjectManager.Submit(so);

Edit: I'm using the SunBurn framework

Need some help with Sprites

David — Fri, 10 May 2013 02:22:52 GMT

I am trying to incorporate the Top-Down 2D demo with my GameState Management which is the one that you can download on here but for some reason the player sprite is very pixelated and can't seem to figure out as to why that is as so far all the code is the same as the one from the Top-Down 2D demo. If someone can try doing the same with the demo and the GameState Management sample to see if they can get it working I'd appreciate it. Also if you see something or make changes to the GameState Management sample to help make it work better please share it as I'm still new to this and I'm sure that one of you vet's could help make the sample better. :)

Getting active Scene from SceneInterface

CJ Bailey — Wed, 08 May 2013 10:12:24 GMT

Since there currently seems no way to get back to the Scene from the SceneInterface I thought this little extension method might help....

public static class SceneInterfaceExtensions
{
    private static IScene _activeScene;

    public static IScene GetActiveScene(this SceneInterface sceneInterface)
    {
        return _activeScene;
    }

    public static void Submit(this SceneInterface sceneInterface, Scene scene, bool dummy)
    {
        _activeScene = scene;
        sceneInterface.Submit(scene);
    }
}

Note that 'dummy' is so called because it's not really needed except for differentiating the method signature from the normal Submit method.

Cheers.

CJ.

Update objects that were submitted

whiskers — Sat, 04 May 2013 12:22:03 GMT

Hi I was wondering if there is any way of updating objects that were submitted through code.

So how would I be able to update it so it's at a new postion?

Sunburn Editor -- A way to have dynamic content display for editing

Valleriani — Thu, 02 May 2013 09:43:34 GMT

Hey there,

I currently have most of my models, scenes/lighting, etc outside of the Content project (That would be built with the game.) Most of my assets are being built at runtime, aka dynamic content. Mainly this is so content can be added or removed without rebuilding the game for something new or changed.

Thing I was wondering however, is the editor when doing it this way and just loading the files directly, do not show any selectable Lights, Materials, Environments, etc, as opposed to actually building it directly into the game. Thus I can't change it using the editor.

Overall it was nice to modify/edit the lighting and such without having to readjust a file. I'm sure I could work on a way to modify it using simple fill in values/adjustables for debug time, but I wanted to see if there is a way to have the content that is dynamically loaded being actually displayed in the sunburn editor.

Thanks!

New Tutorials?

disable fog per SceneObjects

maconbot — Fri, 03 May 2013 05:10:51 GMT

I would like to disable fog on background SceneObjects...I realize I could render them outside of SunBurn and have tried this. Thing is my Scene also has water and reflections in it which hail from within the Scene...rendering the background objects outside of the scene mess up reflections. Worst case I can just disable fog and play with the visible distance but I'd really like to use the fog since we have it!

Please advice if there is anyway to disable SunBurn fog on a SceneObject. Thanks!

Editing Procedurally Defined Scenes

NickMcCrea — Sun, 28 Apr 2013 07:49:38 GMT

Hi there,

Firstly, just a congratulations on the engine. I've recently purchased the pro edition. I looked heavily at Unity (as everyone does) but couldn't really get past the editor and script heavy workflow, lack of Visual Studio integration, and of course the price. Sunburn is a great rendering engine and useful editor that works much more nicely with my IDE-focused development style.

I had a couple of questions.

1. My game will likely feature an in-game level editor, and a majority of my use of the engine is likely to involve procedural scene generation. But it would be useful to be able to edit the scene at runtime via the editor, too, to tweak materials / lighting, try out placement etc. Let's say I generate a scene in code, a few lights and sceneobjects. I hit F11, and of course, although present in the editor render view, nothing is present in the object lists, nothing's editable etc. What would I have to do to make my code-generated scene editable? I'm assuming I'd have to serialize my in-memory objects to a scene file, and load that, instead of submitting objects individually to the sceneInterface? How does the editor work? Does it deserialize the file associated with the currently loaded scene, and generate its model from that?

2. Might be a question from another forum, but I'm looking at the IGF framework, and although I'd like to use it, I'm holding off because no doubt it'll be incompatible (without major work) with the 2.1 platform-independent engine, when it arrives. Does anyone know if there's plans to update it to make IGF platform agnostic?

Thanks!

Nick
