KDOptionalReverse

This script works in T2 (TMA) only. In TG and T1 (TDP), which do not support optional objectives, it only writes an error to the monolog.

The standard VictoryCheck script does not support objectives that are both optional and reverse; it incorrectly marks these as failed instead of completed if they are incomplete at the end of a mission. KDOptionalReverse works around this behavior to allow optional reverse objectives to exist. For each desired optional reverse objective:

• The “real” objective (displayed to the player) should start out incomplete and optional, but not reverse. It should not have any type (steal, kill, loot, location) and nothing in the mission should change its state (other than this script). (Its visibility may be changed as needed.)
• There should instead be an invisible objective that implements the opposite of the actual conditions, whether they are one of the four predefined types or set by quest variable traps. This objective should start out incomplete, invisible, and optional, but not reverse (since it's the opposite).
• If quest variable traps (or other scripts that modify the goal_state_X) are being used, remember that they should be configured to set the opposite of the intended state: for a breach, set to 1 (complete) instead of 3 (failed).
• The invisible objective should have a quest variable goal_negation_X whose value is the number of the “real” objective. For example, if the “real” objective is #3 and the invisible objective is #6, there should be a goal_negation_6 quest variable whose value is 3.

This script should be placed on a fnord other than the starting point. At Sim, it will look for each objective with a goal_negation_X set and begin monitoring its state. Whenever the state of the invisible objective changes, the state of the “real” objective will be updated per the table below. At the end of the mission, this translation will happen again to correct any changes by VictoryCheck.
