set_blueprint_script

REPLACE a blueprint's entire logic by compiling FeatherScript source into its node graph (the fastest way to author behavior — one call instead of many add_graph_node/connect calls). See the FeatherScript section of the engine guide for the language. The source must be the COMPLETE script (start from get_blueprint_script when editing). Syntax errors AND unsupported lines reject the change and leave the previous graph intact — never applied as silent comment nodes. Returns the resulting node/edge counts.
