I'm playing with animation speed and I wanna realize a general script that allow me to put the script on an animated object and change animation speed of the default animation. Now I'm playing with " animation["Walk"].speed = -1.0; " but in this case I need to declare which animation engage for the operation. Is there a way to change speed for the default animation?
Try using the Animation Events Feature of the Animation View & Curve editor.
You could use the curve editor & add animation events that can be called from a script.
