yes but...add the attack animation in the biped script? in the biped script is attack animation but in the bipedinput script no corresponding keypress...for example in the bipedinput is visible this:

if(Key_Pressed(plBipedInput01_move_back_scancode))
{
plBiped01_force_vec.x -= 1; // backwards force
}

etc...
but the attack animation isn't it, How make that if key press for example "Alt", the biped execute this keypress and run the attack animation??

Is hard explication, but please, help me...

I don't know how make this...
