Right now, the biter/spawner items don't attack you if you shoot them, which means you can't create your very own biter zoo. I have a solution to this; an entity wand. This wand works sort of like the Creator wand, except that it makes anything from trees to machines to dead biter corpses. Almost any entity placeable in the map editor should also be placeable here.

I feel like this would be a great way to easily make yourself almost everything, so this might be a neat addition to this mod. Thanks in advance!

There are 2 ways to do this now:
1) Change team in Build Options
2) Use the Modifier magic wand, select the aliens and change their team.
