The Setup

zones.conf

Zone settings can be tricky, Make sure you place the locations in order from the highest number to lowest number. As an example, If corner 1 is located at X:356 Y:62 Z:120 And corner 2 is located at X:240 Y:82 Z:360. Your Zone should be setup as this:

Zone-Settings {
    Amount-Of-Zones=1
    Zone-1 {
        "Display-Name"="Zone-1"
        "Location-In"="world,X,Y,Z"
        "Location-Out"="world,X,Y,Z"
        "Max-X"="356"
        "Max-Y"="82"
        "Max-Z"="360"
        "Min-X"="240"
        "Min-Y"="62"
        "Min-Z"="120"
        "World"="world"
    }
}

And NOT like this:

Zone-Settings {
    Amount-Of-Zones=1
    Zone-1 {
        "Display-Name"="Zone-1"
        "Location-In"="world,X,Y,Z"
        "Location-Out"="world,X,Y,Z"
        "Max-X"="356"
        "Max-Y"="62"
        "Max-Z"="120"
        "Min-X"="240"
        "Min-Y"="82"
        "Min-Z"="360"
        "World"="world"
    }
}

The second setup is wrong, Due to the config being setup as Corner 1 and Corner 2, And not as Max X/Y/Z to Min X/Y/Z.

pokemon.conf

All zones are required to include a Dawn, Day and Night section. In each section should be the following categories, otherwise the plugin will fail, Sections per time of day are Air, Land and Water. Example:

# If you want a different Zone name, For example 'Steppe' Here is how.
# Do the following in the 'zones.conf'

Zone-1 {
        "Display-Name"="Steppe"
        
# Now change pokemon.conf like this:

"Steppe" { # Notice how 'Steppe' is reffered here. Not 'Zone-1'.
    Levels {
        Max=40
        Min=20
    }
    Spawns {
        "Dawn" {
            "Air" {
				        "Spearow"=0.701
				        "Staraptor"=0.701
                "Rattata"=0.605
                "Pidgey"=0.432
			}
			"Land" {
                "Sunkern"=0.701
				        "Spearow"=0.701
				        "Staraptor"=0.701
                "Emolga"=0.605

				        "Burmy"=0.200
				        "Ditto"=0.120
			        	"Bidoof"=0.350
            }
       "Water" {
                "Magikarp"=0.81
                "Barboarch"=0.64
                "Finneon"=0.415
                "Poliwag"=0.19
            }
        }
        
# NOTE: NOT A FULL ZONE. ADD THE REMAINING TIME OF DAY PERIODS YOURSELF!
