- Opcode: 0x12
- Short name: JMPB
- Long name: Jump back
- const UByte A: Amount to jump backwards.
Jumps backward in the current script a specified amount. The jump begins just before the jump opcode itself and then moves the current byte pointer back the specified number of bytes. In the following example, the SOLID and WAIT lines are repeated indefinitely.
SOLID (01) WAIT (70,00) JMPF (05)
If a jump longer than 0xFF is required, use JMPBL instead.
