Now you should learn how to use sprites.
Type SPSET on an empty line and press the blue help button in the upper right. Read the little reference and play around with it.
The management number is a specific number used to work with that one sprite. The definition number is a number used to tell what the sprite looks like.
Do the same thing with SPOFS (help button, empty line).
SPOFS moves sprite.
store every phrase by itself and then store possible responses to that phrase.
if you say something new, the ai will say something random.
if you say something you've already said before, the ai will choose from its list of possible responses to that phrase.
Erm, there is code that does this...
DIM MAP[0]
FOR I=0 TO 3
BGSCREEN I,64,64
LOAD "DAT:SC_<MAPNAME>_L"+STR$(I),MAP,FALSE
BGLOAD I,MAP
NEXT
What you were missing was the SC_ and _L1 prefixes and suffixes.
