I came up with some ideas to improve this trigger and diverse campaigns a little.
- "IS_FLYING" - Obviously, Object start fly. It can be helpful in some campaigns.
- "IS_SAILING/WALKING" - Same ones but instead of being able to fly, unit get all advantages and disadvantages of sailing/walking.
- "STEALTH" - Make unit stealthy (like spy or sniper). VERY helpful for sabotage/spy/stealth campaign maps.
- "SEES_STEALTH" - Make every enemy's stealth unit visible for Object in its sight. Works just like Anti U-boat ships.
- "CAN_OCCUPY" - Object can occupy TCs/AAs/ATs. May be helpful when you need some truck to capture a town.
- "IS_INVISIBLE" - Make Object's sprite invisible. Oh, I want this one so badly. I struggle in some maps where I need to use invisible walls (for example: cliff that player dont need to climb). This would be like the manna from heaven.
