I want to animate a jar: falling down and break. Is a function for that or something else ?
Unless I'm missing something in the question, the function's right there in the manual - Object.Animate (http://www.adventuregamestudio.co.uk/manual/Object.Animate.htm). You may also want Object.Move (http://www.adventuregamestudio.co.uk/manual/Object.Move.htm) for the falling bit - unless you make the 'fall' part of the animation.
Object.Animate is fine for what you want, including the fall of the jar, when the jar is
in the floor "broken" you may want to change the view of the object or use another object. ;)
