A note about event flags
Event flags are calculated from an u16 value like this:
u16 EventFlag; Flag = (EventFlag & 0xFFF) >> 3; Value = 1 << (EventFlag & 7); IsSet = EventFlag & 0x8000
Commands
Opcode | Function | Length | Arguments | Comments |
---|---|---|---|---|
00 | Call | 4 | This command has no stack for return addresses. Nested calls simply overwrite any previous return address, so return is only possible to the most recent call site.
If a simple jump is desired, use command 06 for an async jump, or ASM BRA or JMP for an instantaneous jump. | |
01 | ReturnFrom00 | 1 | If not inside 00-Call, this command is ignored. | |

10 | TriggerOnBlockRelative | 6 | ||
11 | TriggerObjectOnAreaAbsolute | 9 | First parameter is object index, which is multiplied by 40 and added to 1000 to get the object handle, for which the trigger is checked.
Remaining parameters are same as command 0C. | |
12 | TriggerObjectOnAreaRelative | 9 | Broken command.
Supposed to be 0D-counterpart of 11: it should compare the position of the object that is given as first parameter to the position of the object that executes the command, but it uses for both purposes only the object that is given as parameter, which makes it useless. | |
