Set randomSeed to Webots World for correct reproducibility

[angel-ayala]

Hi, I'm trying to set the seed value for random number generator and as mentioned in the documentation that value must be set in the randomSeed field from the WorldInfo Node.

I know that using the Supevisor I can change the field values in any Node during runtime. Can this be done?
Or which is the correct way to set that value?

In Python I'm currently using this line of code to set a seed value.
self.__robot.getFromDef('World').getField('randomSeed').setSFInt32(0 if seed is None else seed)
