Returns the input object or prev_object, depending on whether the current time is a valid simulation step. See the simulation_example for a basic example of how to use this node.

Inputs

object

Connect an object or an array of objects from a simulation computation, to return if the simulation step is valid.

prev_object

Connect an object or an array of objects to return if the simulation step is not valid, for example, the result of the previous simulation computation.

start_frame

The frame at which the simulation starts.

backward

Whether or not to simulate backward.

Output

out_object

The input object, if all the conditions are met.
