If parameter is omitted, default is used.
character: bow ( name = A, speed=2.0, level=20 )
Simultaneous action
character: bow ( name = Bob)
character: bow ( name = Mary )
character: talk ( name = Bob, text = “Hello.")（ Mary bows after Bob finishes
bowing)
character: bow ( name = Bob, wait=no )

・ Open TVML character file and name it as a model name・ Name a character in a script and bind the model name to the
character
Anywhere in a script

CHARACTER
CG Setup
light: flat( name=L1, r=0.70, g=0.70, b=0.70, vx=-1.0, vy=1.0, vz=1.0 )light: point( name=L2, r=0.9, g=0.9, b=0.9, x=0.0, y=1.5, z=-2.0 )
・ Flat light, Point light and Spot light are available・ Enable to turn on/off the named light
camera: position( name=CamA, ry=50, rx=10, rz=0, x=5.0, y=1.0, z=3.0, vangle=45.0 )
camera: switch( name=CamA )
・ Setup a camera and name it and set position, orientation and view angle
・ Enable to switch and move the named camera

CAMERA
CG Setup
prop: openmodel( name=Guitar, filename="Prop\guitar\guitar.obj" )prop: position( name=Guitar, x=0.5, y=1, z=1.5, rx=0, ry=0, rz=0, scale=
1.5 )prop: visible( name=Guitar, switch=off )
・ Open CG data fil and name it・ Set position, orientation and scale of the camera・ Enable to make it visible/invisible
PROP
prop: move( name=Guitar, x=3, y=2, z=1, tspeed=3.5s )prop:openimageplate( name, filename, hsize, vsize, aspect)prop: attach(name, target, joint, switch, x, y, z, rx, ry, rz, scale )
・ Enable to move by specifying the destination・ Enable to use image and movie 2D plate in the 3D world as
prop・ Enable to attach a prop to a joint of a character, etc.
Character animation example
character: talk(name=A, text="Am I speaking in synthesized voice?")character: talkfile(name=A, filename="testsound.mp3")
