Interactive Objects

Most of the code you will be writing will be contained within Interactive Nodes. This is because, in PACgd, Interactive objects are in charge of instructing the Characters how to behave when interacting with them.

Making an Object Interactive

In order to use an object in PACgd you need two things:

1. To attach an script to the Object, and extend the class Interactive
2. To add a CollisionShape to the Object, so the PointClick system can detect it.

The Interactive Class

Interactive objects have six main properties:

• main_action, secondary_action: These properties determine what happens when the player clicks on the object using the primary or secondary click (left and right mouse buttons by default).
  • Its value has to be an Action. See actions documentation for options.
  • The default primary and secondary actions are ACTIONS.walk_to and ACTIONS.examine.
• interaction_position: A Vector indicating the spatial position in which the Character must stand to interact with the object.
• description: The description of the object when it is examined.
• thumbnail: The thumbnail to display in the Inventory after the object is grabbed.
• interactive: A Boolean flag indicating if the PointClick system should interact with the object or not.

Actions on an Object

The main_action and secondary_action determine the methods the object needs to implement. For example, if the main action is ACTIONS.take the object must implement the method take(who) (see Action documentation). Within such method, the object must call different Characters methods in order to instruct the Character on what to do (see Character documentation). You can find examples on how to do this in our Quickstart tutorial.
