A ValueTable stores time/value pairs and has an output slot that holds the appropriate value for the current time. The type of the value can be specified in the constructor. The name of the output slot is always output_slot.
type is the type of the values stored in the component. This is also the type of the output slot.
values is a list of initial time/value pairs. Each item must be a 2-tuple (time, value).
modulo is the duration of the loop. The animation sequence will be replayed after modulo seconds. The sequence will not repeat if modulo is None.
tscale is a scaling factor for the time. Values smaller than 1.0 will slow down the animation.
Add a new time/value pair to the table. The value v must be of the appropriate type.
The values can either be added using the add() method or using the index operator. If you want to retrieve the value for a particular time (without using the value slot) then you can either use the call operator or the index operator:
>>> vt=ValueTable(type="double") >>> vt.add(0.0, 1.0) >>> vt[0.5] = 2.0 >>> list(vt) [(0.0, 1.0), (0.5, 2.0)] >>> vt(0.2) 1.0 >>> vt[1.5] 2.0
You can iterate over a ValueTable to get the time/value pairs:
>>> vt=ValueTable(type="double") >>> vt.add(0, 1) >>> vt.add(1.5, -2) >>> vt.add(1.0, 0.5) >>> for t,v in vt: print t,v ... 0 1 1.0 0.5 1.5 -2
