BboxSensor2D
This sensor can be used to monitor the bounding-boxes of any node in the scene-graph. It sends bbox_changed events if the global bboxes of the node changed. Every bbox is defined by a min/ max pair in screen coordinates. Since the system is a multiparent graph a node can have more than one global bbox and therefor the bbox_changed outslot can send more than one min/ max pair.

description | SFString | inputOutput | Text description to comment the sensor task. Can be used in run-time systems to give usefull feedback to the user and developer | |||
triggerName | SFString | initializeOnly | Synchronize | name of the dynamic context-slot which is used by the run-time environment (e.g. Jobs) to trigger the node. Life-Nodes will automatically connect the context-eventOutut to the triggerSlot-eventInput Slot. | ||
triggerSlot | SFTime | inputOnly | slot which is used internally to connect a dynamic context-slot which name is set by the triggerName value. Its used automatically to install run-time environment trigger. |
