Is there a replacement for "temp" in lite-c? I remember temp being very useful because it didn't need to be typecast.

Also for Vectors, is there a vector implementation for C/C-lite, or do we have to write our own?

VECTOR* can be used for vectors. var temp doesn't need typecast. In fact, nothing needs typecast in c-script, and only a minor amount of code needs typecast in Lite-C. That said, it's not harmful to typecast everything that needs it. In fact, I'd make that common courtesy.

x/y/z, tilt/pan/roll and red/green/blue

are declared as:

VECTOR ANGLE COLOR

respectively.
