How do I make a ghost nuke instantly?

It honestly is not possible.

Now, there are ways you can make effects similar to it.

If you preplace nuke explosion sprites, they explode at the start of map, and you can kill units around them if you want. Of course, that only happens at the start so it's not really useful.

The next best effect is just a big explosion of dying units and then kill units under it.

Or you can take the wait and actually do a nuke.

Maybe you could have a computer controlled ghost with AI script nuke here and infinite nukes or w/e, and teleport both ghost and the unit/location it is targeting to where you want it, but I dont know if that would work.

I Cant even get the stupid AI script to work becuase I faillll
