local player1 = {
    name="Player1",
    id=1,
    location = {
        x=1.0001,
        y=2.0003
    }
}
local player2 = {
    name="Player2",
    id=2,
    location = {
        x=30.123,

    id=1,
    status="active",
    location = {
        x=1,
        y=2
    }
})
-- list of monsters (1 monster is available)
print(yaml.encode(pokemon:map()))
-- Player 1 can catch it
print(pokemon:catch(1, player1)) -- true
-- Player 2 can't
print(pokemon:catch(1, player2)) -- false
-- Monser map is empty
print(yaml.encode(pokemon:map()))
