Hello, hello, plants vs. zombies are popular for many years, from sunflowers that shake their heads to tutuku ⚾⚾⚾ pea shooters spitting bullets! Slow-moving, diverse zombies… The most memorable was “Zombies eat your brains!” And crazy Dave, all of them reminding us of our childhood. Use Python to restore your childhood memory.

​

The functions are as follows:

  • Supported plant types: sunflowers, pea shooters, nuts.

  • Supported zombie types: Normal zombie, chess zombie, barricade zombie, iron bucket zombie.

  • Use JSON files to save level information and set the time and location of zombies.

  • Increased the selection of playing plants at the start of each level.
