[Modset4.2] Open BrawlBox/Lib Development Thread [PW's SSS support(PAT0 editing)]

[SqLeon]

I didn't think it was that easy..Cause Brawl has it's own folders for Snapshots, replays, and all that. I figured there was a reason for the "pf" folder, otherwise what's the point of making it? I could just make another folder with a different name that would have the same results. Or am I wrong?

the code uses the name pf

 

[DAGanmanert]

the code uses the name pf

Thanks, then. At least I know now. (I started with all this yesturday.)

 

[Altres]

Hey, i'm 12 and want to learn how to do this stuff, anybody willing to help?

 

[NO@H]

wrong place, try here, perfect for 12 year olds

or, if you meant C# editing, see OP, there is good links on learning C#. I suggest learning the basics by making a hello world or something before attempting to edit brawlbox

 

[libertyernie]

I noticed the newest version uses .NET framework 4. Is there any way to compile it against an older version so it will run on Linux/Wine?

 

[Bero]

I'm very sorry... You have to rewrite all codes which is using .NET 4.0.

By the way, something is coming soon...

 

[Dantarion]

Please say you figured out some of the AI

 

[Bero]

I'm sorry but I have to say no.
That thing is for animators.

AI can be understood only by you,I think.

 

[pikazz]

wow, I can't wait for the surprise :D

can you click/drag bones in the model previewer?

 

[SqLeon]

can you click/drag bones in the model previewer?

that would be amazing beyond belief

 

[Bero]

But I haven't studied vector and matrix,you have to wait for a while.
(in fact, I have tried this for 2 weeks.)

 

[Ultraxwing]

if we could click and drag bones in the model previewer, i think most model import character's would be doen 3X faster than they originally are being done now.

But I haven't studied vector and matrix,you have to wait for a while.
(in fact, I have tried this for 2 weeks.)

Hit-detection can be done by translating the 2d viewport coordinates to 3d model coordinates. The mathematics for this has already been done, and is part of the GLPanel class. Take a look at System.Windows.Forms.CollisionEditor (MouseDown and PostRender events) and BrawlLib.OpenGL.GLPanel (GetDepth and UnProject methods).

What I did in this instance was perform rendering in two parts:

1. Allow attached scene objects to be rendered normally by the GLPanel.
2. Add a PostRender event to clear the depth buffer (not the color buffer!) and draw your interactive elements.

What this is essentially doing is splitting up the render sequence into two passes: the first for normal rendering; second for interactive rendering. The difference is in the depth buffer. Since it has been cleared, only interactive objects will have a depth > 1 in the viewport. How do we use this?

When the user clicks the mouse, we can transform that viewport coordinate into 3d space using the UnProject method. We can also get the recorded depth from within the depth buffer by using the GetDepth method. What you do is first get the depth value for the mouse point. If the depth is > 1 we know we've clicked on an interactive object. Then, pass that depth value along with the mouse position to UnProject, which will give you the world coordinates of that point at that depth.

Proceed to search through your objects and find one that most closely matches that point. Examples can't be given here since SSBB collision objects are all two-dimensional. However, there should be some useful functions in the Vector3 class.

You could combine this with colors to determine what types of objects were selected. OpenGL has a method for getting screen colors. Just make sure they are unique and opaque.

 

[Bero]

Thanks for informations! I can now understand your way in collision editor.

At first, I tried to do the same way of Collision Editor. But because I didn't make sense of it, I decided to use "Selection Mode".
I managed to make selection system 10 days ago, but I have a trouble with "drag-and-drop" function.
Because each bones have different rotation and coordinates, I can't find a good way to rotate bones.

Would you do me a favor and tell me some hints to do that?

Tips:

• Remember that a bone segment consists of a line then a point.
• Transformations occur in this order: translate, rotate, scale.
• When you rotate a bone, you are making changes to the child bones. Even though the node rotates, translation has already been applied and doesn't affect the node's location.
• To get the world position of a bone, use its bind/frame matrix. The values in the 4th column are the XYZ coordinates.

After hit-detection, highlight the bone node and render a sphere around it. You can use the bone's Frame Matrix to achieve a local coordinate system (just multiply this to the modelview matrix). Once in a local coordinate system, you can simply render the sphere. You don't need to apply any other changes to it, the matrix does all the work for you!

Once you have a bone chosen and a sphere to render, use the same two-pass depth buffer trick. This time, you're going to hit-detect the sphere first. To make tings easier, you may consider setting the depth buffer exclusively for the sphere. Any depth value < 1 means the user did not click the sphere, and you can cancel the selection.

Once you have the world-coordinates of the user-selected point, transform this to the bone's local coordinates using its Inverse Frame Matrix (just multiply the point by the matrix). Now that we have a local point, the rest is fairly easy. When the user FIRST clicks the sphere, do two things:

1. Calculate the XYZ angles of the clicked point using trigonometry. (these will be your origin angles)
2. Use these angles to determine axis-snapping. (If the x-axis is the only one with an angle, we can safely snap to it)

As the user moves the mouse around, repeat the point+depth -> local point process. Calculate the XYZ angles each time, and subtract the origin angles. This will give you an 'angle offset', for which you can apply to the FrameState or AnimationFrame (just add them together).

 

[Bero]

Thanks again!

I didn't notice that I have to multiply Inverse Frame Matrix of only selected bone.
I'll give it a try!

Bero - Is there any chance you could make two buttons that only copy/paste the bone translations for one frame?

It would make porting animations between characters incredibly simple, instead of 40 minutes of tedious copy/paste.

 

[Bero]

@Shadic
BrawlBox will have that function in next update.

@Kryal
I'm not sure if you see this...

I tried to do what you said but things don't go well...
This is my code:

        /// <summary>
        /// Calculate angle of clicked position
        /// </summary>
        /// <param name="x">X coordinate of mouse</param>
        /// <param name="y">Y coordinate of mouse</param>
        /// <returns>Vector which contains xyz angle</returns>
        private Vector3 CalcAngle(int x, int y)
        {
            Vector3 vec = new Vector3();

            var depth = GetDepth(x, y);
            var point = UnProject(x, y, depth);

            point = ((MDL0BoneNode)SelectedBone.Parent)._frameState._iTransform * point;
            vec._x = (float)(Math.Atan(Math.Atan2(point._y, point._z)) * 180 / Math.PI);
            vec._y = (float)(Math.Atan(Math.Atan2(point._z, point._x)) * 180 / Math.PI);
            vec._z = (float)(Math.Atan(Math.Atan2(point._x, point._y)) * 180 / Math.PI);
            return vec;
        }

I think world->local translating isn't working well. Is iTransform is the thing which you called "Inverse Frame Matrix"?

 

[Shadic]

@Shadic
BrawlBox will have that function in next update.

You have no idea how happy you made me.

 

[Kryal]

Oops, you're right. There is no inverse frame matrix. Those FrameState structs are all relative, so you can't use those. You will need to create an inverse frame matrix. Look at RecalcBindState and ApplyCHR0. Suggestions:

• Split ApplyCHR0 into two functions. One for actually retrieving the FrameState, and one for recalculating the matrices.
• Any time you change the FrameState, you need to recalculate the Influence matrices and re-weight the vertices. (Look at ApplyCHR in MDL0Node)
• When you get this working, test free-rotation without the z angle. When you have three axis of rotation, circular movement can cause the angles to progressively deviate. This is why cameras usually use two axis instead of three.

Your trig looks good. I would double-check the z angle.

 

[Bero]

@Kryal
Thanks for all information, but I still failed to make this(I may be making mistakes)
Bones seem to follow mouse, but move is awkward and they goes everywhere...


Well, because I have little time to do this, it takes long time to achieve this function.

 

[Kryal]

Yeah, it's harder in practice because something always goes awry. Sporadic and irregular movement is usually caused by a corrupt matrix. If the vertices act as expected then you're halfway there, because you know the vertices have been weighted properly.

If I get a chance I'll look at it this weekend and try getting some code together.

 

[Bero]

That sounds great !
It seems that I have to fix my very dirty codes and commit them...

 

[Kryal]

Okay, I got mouse-picking and angle calculations for bones. Of course, it is a little more involved than I originally thought. I will update the BrawlTools SVN when I finish and you can just cut-paste the changes. You don't have to worry about committing.

 

[Bero]

HaHa! That's just what one would expect of Kryal!
I will be able to study a lot from your code.

 

[Eternal Yoshi]

How do you make something that was not editable in Brawlbox editable?

I'm talking mainly about the colors section of Mdl0s.

I'm trying to recolor Tabuu, but there are hundreds of Color values and editing them by hex is difficult since each entry is only 2 bytes.

 

[AMKalmar]

Just a request, I'd like be able to preview models in orthogonal projection rather than perspective.

 

[Kryal]

Okay, almost done. I need to tweak a few more things and then I'll post the code. Probably in the next few days or so.

 

[NO@H]

[Bero]

(I thought you had already done by 10-31-2010)

I'm looking forward to seeing your code! Well,I have to begin making other new functions...

BTW, the above should fix adding icons to the CSS as well.

this might be handy by looking for the rest in PAT0 hacking :D

 

[Tiberious]

Umm, thread's gotten TL;DR, but what's the status on exporting in BrawlBox? I hadn't had much luck with anything, but for the most part, the converter Pharrox made usually works (with those 3 notable exceptions in the Alloys).

Also, has there been any thought given to showing weighting information for models? As in... well, think like the Weight Paint mode in Blender. It shows (and allows editing of) weighting for various bones. Being able to see that kind of detailed information will be very helpful in getting my rigging right in a virtual world.

 

[Eternal Yoshi]

It's going to be a long time before we get to that.
As of now, if you look at the previous posts, there are clues that soon we will be able to drag and drop bones with the mouse in the model viewer, making animation making much faster.

Also the PAT0 format.

 

[AMKalmar]

Any reason why I can't import a colour animation (CLR0) into a brres the same way I can import a model, animation, or texture?

 

[Mewtwo_2000]

Any reason why I can't import a colour animation (CLR0) into a brres the same way I can import a model, animation, or texture?

Yeah, that's something that needs to be fixed I guess, as well as renaming the CLR0s you have.

Anyway, if you need importing any colour animation into a brres file, send me both the brres and the CLR0 via PMand I will do it for ya. I have some tricks by hex editing, similar to what I used when the 'add model' option was glitchy.

 

[AMKalmar]

I know it's more work to explain than it is to do yourself, but could you just tell me how to do it?
