Byte, Int, Float

cast a Node_Data Data_Array to be of type byte, int, or float

Description

Byte, Int, and Float are field subtypes that will conveniently transform all apropos subobjects in a Node_Data Data_Array to the corresponding type.

For example, saying

Field_Unif+Byte

types the field as containing byte Node_Data.
