In object-oriented terms an attribute is something that describes an object. For example the colour of a pen would be an attribute. In BlitzMax, the keyword Field is used to denote an attribute. A field is like a variable but it can only be accessed from a class instance using the dot (.) operator. The following sample code is correct. It is assumed that star is an instance (object) of the TStar class and that BlitzMax is in graphics mode (using the Graphics keyword).

Local star:TStar = TStar.Create(50, 50, 255, 255,

255)
