A system, a machine-readable storage medium storing instructions, and a computer-implemented method are described herein to define an animation of a virtual object within a virtual world. The animation comprises performing, at each of a series of time points, an update that updates values for object attributes of the virtual object. A user is allowed to define the animation by specifying a structure representing the animation. The structure comprises a plurality of items and one or more connections between respective items. Each item represents a respective operation that may be performed when performing the update. A connection between two items represents that respective output data generated by the operation represented by a first one of the two items is input to the operation represented by the other of the two items. |
