How To

Class?

Is their any way for me to make an object or class? I know there isn't but maybe using other commands you could simulate it? It would be very useful for sprites. Also any tips in general. Thank you!

Yes....kinda...

by using arrays indexed 0-63.. then

Then make other arrays using the same indexs, so any change in any other array references each other, so changes to index 5 affects sprite 5

Also, then, a non indexed array can be used to affect a range or all sprites at once...

Yes, a big part of classes you can simulate with arrays, also independently from sprites.
I'll try to explain when I'm less tired...

Imagine this in a C++-like language:

class Enemy {
   int x
   int y
   void move() {
      x=x+1
      y=y+1
   }
}

Enemy enemies[10]
for (int i = 0; i < 10; i++) {
   enemies[i].move()
}

You could do something similar in BASIC like this:

DIM GLOBAL X(9),Y(9)

SUB MOVEENEMY(N)
   X(N)=X(N)+1
   Y(N)=Y(N)+1
END SUB

FOR I=0 TO 9
   CALL MOVEENEMY(I)
NEXT I

Basic+Subs i understand intuitively like i can understand decimal math intuitively..

C to me is like BIT math... I "CAN" understand it, but it isn't intuitive, it takes me more time to think about it to get it right...
