31110: Make a character speak (1)
The address of this interruptible subcommand routine is placed into bytes 105 and 106 of a character's buffer by the routines at 31282, 31996 and 62464. The subcommand terminates if the character is off-screen; otherwise it waits for anybody else to stop speaking before printing the speech bubble above the character's head and handing over control to the routine at 31130.
Input
H Character number (152-169)
31110 LD L,110 Zero out bytes 109 and 110 of the character's buffer, which normally hold the address of the next character in the submessage being spoken (when a character starts speaking, there is no submessage)
31112 XOR A
31113 LD (HL),A
31114 DEC L
31115 LD (HL),A
This entry point is used while the character is waiting for someone else to stop speaking.
31116 CALL 29518 Make the character start speaking if possible
31119 JP C,25252 Terminate this interruptible subcommand if the character is off-screen
31122 LD L,105 Set the interruptible subcommand routine address in bytes 105 and 106 of the character's buffer to the entry point at 31116
31124 LD (HL),140
31126 RET NZ Return if somebody else is speaking at the moment
Now it's this character's turn to speak.
31127 LD (HL),154 Set the interruptible subcommand routine address in bytes 105 and 106 of the character's buffer to 31130
31129 RET
