Hello,
I'm just making my first missions with  the Mission Builder and I have follow questions:

Is there any possibility or trick to vanish or remove units from the mission ?
For example if I want simulate that a submarine is diving at a special waypoint.

Is there a possibility to damage a unit caused by a trigger ?
For example if I want simulate a submarine attack on another ship .

Thank you for your answers.

You can use a trigger to add damage to an aircraft but not a ship.   Unfortunately the only damage option you have for a plane is an engine fire. 

You can preset damage to a ship (or anything else including infrastructure) at the time you first select it but that level of damage will be there from the start of the sim.  As a general rule that preset damage is not visible but does make the ship, etc. easier to destroy.

I know of no way to make an object "unspawn".  I've written missions where the goal is for the player to sink a submarine before it dives.  I do that by spawning the sub then giving the player a set amount of time, say 5 minutes, to find and sink the sub.  At the end of that time period the mission ends.  I use different debriefs depending on whether of not the player sunk the sub in time.  It works, but does result in the mission ending.

Hi Dave,

I was thinking about your sub question.

You might try to turn your sub into a flyable unit.
Someone did this for the PT Boat.
An ultralight air file might be used.
Change the model ref. point in the config. file to -200ft or whatever and when you put the unit at an alt. of 200ft the sub should be on the top of the water.

I have no idea if this work but I don't see why not.
