Is it possible to make larva and since im making a map dodge the spikes how come it only attacks one unit i put on the map instead of attacking all the other at the same time?
No, it's not possible to create a larva. You have to store it somewhere else and move it where you want it. I don't really understand the second question...
The second question is that when i put other larvae on the map it only attackas one at a time and i mean i have 200 lurkers its bound to a ttack the other larvae right?
Well, every once in a while stray spikes will go out, but I don't think you can get them to attack all of them all the time.
If all the lurkers are at the same spot chances are they will all attack the same thing, put lurkers in different places and it might work.
Well this might not be a perfect solution, but maybe you could make different larva at different times invincible. Then the lurkers would have to attack other larva.
When all the lurkers are in the same place they aquire the same target based on where it is located. It doesn't take into acount weathor or not any other units are attacking it or how pretty it will look. Just like Kumano said.
To get more larvae just stack a ton of Hatcheries.
If you move the larva, it will try to go back to its hatchery...
