Main loop: Delay

       Name: Delay                                                   [Show more]
       Type: Subroutine
   Category: Main loop
    Summary: Delay for a specified number of loops
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * MoveAndDrawCars calls Delay


 This routine performs T + (5 * 256) loop iterations, to create a delay. The
 value of T doesn't have much effect on the amount of delay, so it looks like
 this variable was chosen simply because it doesn't contain anything useful at
 this point.


.Delay

 LDX #6                 \ Set X as the counter for the outer loop

.dely1

 DEC T                  \ Loop around for T iterations in the inner loop
 BNE dely1

 DEX                    \ Loop around for X iterations in the outer loop
 BNE dely1

 RTS                    \ Return from the subroutine
