How to create avatar animations

How to create avatar animations ?

To create a new animation, open your inventory, click right and choose the menu New > BVH
That creates a new MyBVH.

To edit an animation, open your inventory, click right on a BVH and choose the menu Edit.

Buttons:

AVATAR : when creating couple animations, switches between avatars A and B.
SMOOTH : removes a red ball and smooths the values between the left and right red balls.
ZERO : sets a neutral rotation 0,0,0
UNDO : restore previous rotation
COPY : copy rotations
PASTE : paste the copied rotations
PLAY : play the animation on the avatar
PRIORITY : 0 (low) to 7 (high) - use 4 for furniture.
FPS : speed in frames per second.
LOOP : repeats the animation between 1st-frame and last-frame.
INVERT HEELS : By default, the height of an avatar in heels is increased if she's walking, and remains unchanged if she's sitting. By checking this option, the opposite is done : the height is increased for a seated avatar, but not if she's walking. For the vast majority of animations, you should NOT check this option, as it is only useful in a few rare cases, ex: crawl on the floor. Always test your animation with and without heels.
Apply : save animation to inventory.
OK : save animation to inventory and closes dialog.
Cancel : close dialog without saving.

To display all bones, right-click on "Expand Bones".
To hide all unused bones, right-click on "Shrink Bones".

To insert frames, right-click on "Insert Frames".
To remove frames, right-click on "Delete Frames".

To add an animation in furniture :

edit the furniture object and go in the SCRIPTs tab.
Drag/drop the animation from the inventory into the object's scripts tab.
Write a little script to make it work, for example :


// Example 1 : dancing ball

const string ANIMATION_NAME = "dancing";

event touch()
{
  key k = touched_avatar();

  if (is_animation_active (ANIMATION_NAME, k))
    stop_animation (ANIMATION_NAME, k);
  else
    start_animation (ANIMATION_NAME, k);
}

 
// Example 2 : sit on a chair

event touch()
{
  key k = touched_avatar();

  if (is_sitting (k))
  {
    unsit (k);
  }
  else if (sit (mesh_nr  => 1,
                position => {0.0, 0.0, 1.0},
                rotation => {0.0, 0.0, 0.0},
                avatar   => k))
  {
    start_animation ("sit", k);
  }
}

Alternatively, you can create an animation with an extern program, for example QAvimator, and then import it in your inventory.
