PlayableGraph.Connect

Parámetros

Valor de retorno

bool Returns true if connection is successful.

Descripción

Connects two Playable instances.

The connections determine the topology of the PlayableGraph and how it is evaluated.

Playables can be connected together to form a tree structure. Each Playable has a set of inputs and a set of outputs. These can be viewed as “slots” where other Playables can be attached to.

When a Playable is first created, its input count is reset to 0, meaning that it has no children Playables attached. Outputs behave a little differently—every Playable has a default output created when first created.

You connect Playables together using the method PlayableGraph.Connect, and you can disconnect them from each other using PlayableGraph.Disconnect.

There is no limit set on the amount of inputs a Playable can have.
