Well, every natural plant have seeds. They need to reproduce. Those without seeds go extinct in one generation.

In Go you can compare structure instances with == (by value). You can also compare pointers (in which case they can be different even if values are equal). You get what you ask for.

Also, I’ve never needed “Equals” method in Go.

Usually I load machine gun turrets manually. And use them mainly to clear nests early in the game. Later, when I get my hands on oil, I build perimeter with walls, flame and laser turrets. Connect pipes with oil and connect electricity. That do the trick.
