An Ageable Entity is one that grows over time, like a cow.
Importing the package
It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import.
Methods expect an int and the second method an optional bool.
Both methods return nothing.
Normally, the second method does the same as the first with false as forced argument, that may differ for mod implementations, though.
entAgObj.ageUp(int seconds, @Optional boolean forced); entAgObj.addGrowth(int seconds);
