Syntax

class FFieldSystemCommand

Remarks

FieldCommand

Field commands are issued on the game thread and trigger field evaluation during game play. The Commands will store the root node in the evaluation graph, and will trigger a full evaluation of all the nodes in the graph. The MetaData within the command will be passed to the evaluation of the field.
