You can add blueprints to the whole scene or to an object.

   This is the Blueprint Editor where you can create scenarios using blueprints.

Add blueprints to objects

When a blueprint scenario is attached to an object, the scenario has direct access to this object. Some of the nodes that require an object (actor) can use this object as an input parameter (see the nodes list).

For example, for a scenario is attached to a sound actor, you do not need to directly pass an actor to a Play Sound node (see the Add Sounds chapter of the tutorial).

To add a blueprint scenario to an object:

1. In Inspector, open the full view of the object.

2. Add the Prop Blueprints property to the object: click + to the right of the object's name, select prop_blueprints and click Apply:
