Who wants to write an editor for Flancedoor?


Dance file format:

Byte offset Byte length Description

+0 1 Version number (this field is ignored)
+1 1 Number of moves in dance

+2 Variable Move definition
+2 + sizeof(Move def1 ...etc

Move format:

+0 13 Name of move
+13 1 Number of frames in move
+14 26 Frame definition
+40 26 ...etc

Frame format:

+0 2 XY coords
+2 2 XY coords
+4 2 XY coords
+6 2 XY coords
+8 2 XY coords
+10 2 XY coords
+12 2 XY coords
+14 2 XY coords
+16 2 XY coords
+18 2 XY coords
+20 2 XY coords
+22 2 XY coords
+24 1 Number of frames to interpolate over
+25 1 Displacement of each interpolated frame
(8 bit signed)

So a dance consists of a number of moves which each
consist of a number of key frames which are interpolated
between.

The current dance files are breakdance.raw,
stonkdance.raw & princedance.raw, they are located
in /empeg/lib/visuals/

Oh yeah, that would rock. Let's do The Time Warp again!

First person who implements "The Hustle", however, gets slapped.

I can't believe that you gave slapping preference to the Hustle over the Macarena.

I prefer the Rico Suave dance myself... or, the "shopping cart".

Damn forgot about that one. Must have blocked the painful memory out of my mind. Okay, Hustle and Macarena both get a slap.

(Watch, they'll be the first to get implemented. )

hey...does this mean that you know how it decides how many dancers to use?
I've been trying to figure that out with no luck

The number of dancers is simply random as far as I can tell.

yeah, that's what I thought and it seems to change on some power cycles, but not all
(never when I want to show someone how cool it is that the number changes)

If you want to change the number of dancers, just press the "Select Mode" button on the Rio Remote. This button re-seeds the visuals. This one is in the Button Guide, here.

If this kicks off, then we have to attach GENRE keywords to each flancedoor file, so that when a song of a partcular genre pops up, it will dance the appropriate style!

Please!

Or the bus stop?

I gave it a shot tonight and got moderately far on a reader and emulator for it, but am very busy and probably won't have a chance to work on it again for a long time, probably longer than the BBS folk around here will want to wait for code (Mark has seriously spoiled you'all). Besides, I was doing it in VB, which would probably make quite a few people unhappy around here.

I will share what I learned though if someone else wants to play with it.

Of course it is a tree structure, with a file containing the header, which has many moves, each move having many frames. The XY coords are for the joints, ordered like this.

1. shoulders
2. right elbow
3. right hand
4. left elbow
5. left hand
6. lower body
7. right knee
8. right ankle
9. right foot
10. left knee
11. left ankle
12. left foot

The player will reverse the images at its whim though, so left and right are kind of meaningless. It seems that the head is always attached to the shoulders (DUH), and always perfectly in line with the body segment between 1 and 6.

It appears that the last move is always just 1 frame and is the person just standing there.

The co-ords are reversed, with 0 being the bottom of the screen. (again, left and right are pretty irrelevent)

Hope that helps anyone else's shot at this. I was hoping to get it done enough to get Mark's Time Warp made, but I'm still several hours away.
