Not natively. You can do it with script, or sort of hack it with a moving animation that looks like running, but otherwise the AI never runs without Chase mode enabled.
Thank you for replay Dc. And do you have in your mind, any suggestions of Script I would force Ai use Run without setting a chase? I has in mind...Maybe rename run animation to some attack with "range" stopping when closer of opponent. But, would be nice one script used on stage to realy change native prop.
