add_string — DRIVE kendamaworld op

• Data kinds: table → scalar

• Call: import fullseye as fs; fs.ledger.add_string(world: 'dict', p_ball, p_cup, *, radius: 'float' = 0.0015, color=(0.18, 0.18, 0.2), name: 'str' = 'string') -> 'int' (to call the implementation directly, import kendamaworld; kendamaworld.add_string(world: 'dict', p_ball, p_cup, *, radius: 'float' = 0.0015, color=(0.18, 0.18, 0.2), name: 'str' = 'string') -> 'int'; from the registry, opsdrive.get("add_string"))

Usage

Adds the string (label 29, dark gray) to the world. Returns the index into objects.
