  • If a vector is stored in a list as "<7,5,0>" (as a string type, as opposed to <7,5,0> which is a vector type), its type will be returned as TYPE_STRING, not TYPE_VECTOR. The same applies for "1" being returned as a string instead of an integer, etc. There is no easy way to guess what the type should be from a string value. The users intent may not be obvious

Type Description
TYPE_INTEGER 1 integer
TYPE_FLOAT 2 float
TYPE_STRING 3 string
TYPE_KEY 4 key
TYPE_VECTOR 5 vector
TYPE_ROTATION 6 rotation
TYPE_INVALID 0 none
