24935: Print score
Used by the routines at reset_score_update_high, draw_lives_remaining and award_spaceship_bonus.
Input
C cy
B cx
HL value to print (the score or high score)
A number of digits
print_score 24935 LD (_DIGITS_LEFT_TO_PRINT),A Stash A
24938 PUSH BC Push cx,cy location to print at
24939 CALL gen_printable_score IX points to the 5 digits to print
24942 LD A,(_DIGITS_LEFT_TO_PRINT) Recover A
24945 NEG 2s complement
24947 ADD A,5 If A is less than the assumed length of 5 digits we bump IX along to reduce the length of the number printed.
24949 JR Z,print_score_1
print_score_0 24951 INC IX
24953 DEC A
24954 JR NZ,print_score_0
print_score_1 24956 LD A,(IX+0) A contains digit to print
24959 INC IX Next digit
24961 CALL find_digit_udg HL points to UDG
24964 POP BC Retrieve x,y
24965 LD D,B Use DE to add one to the cx value, push ready for next iteration, it's taken off by the POP BC
24966 LD E,C
24967 INC E
24968 PUSH DE
24969 CALL print_udg Print digit
24972 LD A,(_DIGITS_LEFT_TO_PRINT) One more done
24975 DEC A
24976 LD (_DIGITS_LEFT_TO_PRINT),A
24979 JR NZ,print_score_1 Back to print next digit
24981 XOR A Find digit 0 and jump to print it. Tags an extra '0' on the end, this is the x10 multiplier
24982 CALL find_digit_udg
24985 POP BC
24986 JP print_udg
