The solution is solved but stackoverflow wont allow me to remove the question. The reason I would like the question removed because the answer provided isnt the solution so it would just throw other people off.
Ok the solution is as follows:
In this section of code this is going through a portion of the search space and evaluating the game states based on the best moves for each player. Through this algorithm the AI knows the best moves for each player and can make a "good" move.
if maximizingPlayer:
maxValue = -1000000
for move in range(0, self.COLUMNS):
tmpBoard = self.copyBoard(board)
if self.is_legal_move(move, tmpBoard):
self.drop_piece_computer(move, tmpBoard, moveNumber)
result = self.generate_move(tmpBoard, depth - 1, computerPlayer, humanPlayer, False, moveNumber + 1)
if result >= maxValue:
maxValue = result
bestMove = move
return bestMove
else:
minValue = 1000000
for move in range(0,self.COLUMNS):
tmpBoard = self.copyBoard(board)
if self.is_legal_move(move, tmpBoard):
self.drop_piece_computer(move, tmpBoard, moveNumber)
result = self.generate_move(tmpBoard, depth - 1, humanPlayer, humanPlayer, True, moveNumber + 1)
if result <= minValue:
minValue = result
thismove = move
return thismove
However, if you look closely when I recursively call the function back to the AI in the !maximizing player function I have:
result = self.generate_move(tmpBoard, depth - 1, humanPlayer, humanPlayer, True, moveNumber + 1)
In words when a simulated human player was playing on a generic board to generate the ai move it was assuming that there were 2 human players, and thats why the halt would happen because you cannot have a game with 2 of the same player.
so changing:
result = self.generate_move(tmpBoard, depth - 1, humanPlayer, humanPlayer, True, moveNumber + 1)
to this:
result = self.generate_move(tmpBoard, depth - 1, computerPlayer, humanPlayer, True, moveNumber + 1)
Putting False instead of True in the if maximizingPlayer block and True instead of False in the else clause for the second to last argument to the recursive calls to generate_move seems to fix the game.
i.e. Change False on line 33 of Minimax.py to True and change the True on line 44 to False.
A snake game was created using Pygame and I tried to solve it using an AI. Initially I didn't increase the body length to check if the snake head moves towards the food. Grid size is 5*5. DDQN network was used. Most of time the head moves towards the wall or gets struck in a continuous loop.The maximum score attained was 4 even if I train it for 5000 episodes.
State: It is an array of size 16. The first 8 values has the distance between the head and wall at 8 directions(left , left top, top, right top, right , right bottom, bottom, left bottom). Next 8 values has the distance between head and food at 8 directions. All the values are in the range 0 to 1. 1 means the object is near and 0 means it is very far.
Action : There are 3 actions 0,1,2. 0- Head moves in same direction. 1- Head turns left. 2- Head turns right.
Reward: Reward of +50 if it collects the food and reward of -200 if it touches the wall.
I am not able to understand why my neural network learns in the wrong way. Please do help me solve this issue. I have attached the code here.

A few things you could try:
The way you have defined your state looks a little complicated. Won't top and bottom give the same information, one being negative of the other? Also if your snake head is at (1,1) and your fruit at (3,4), well then the fruit won't show up in the state at all. There will be very limited times when the snake agent can actually see the fruit. Maybe you can try defining the state another way?
In RL, things go south very frequently so it often makes sense to start with basic agents and basic games and move up the ladder. Try using the same agent for a simple openai gym environment like mountaincar, to check if the agent class works as intended.
Quick question. I have my Player Class, working perfectly. Except for a small detail. This is the class:

Since to update the Player's sprite, I need to call the "load_sprite" function, which causes the animation to be constantly called. As a result, the same animation does not appear and remains still at the first frame. So how could I solve?
Edit: Modified the script, including the for loop. If you see, I modified the group, using Batch and OrderedGroup instead. In this way we can clearly see the problem I am having.
The problem I have is due to the fact that pyglet.sprite.Sprite is called in order to update which animation is executed. However, doing so at the same time, the animations are not shown exactly because of the constant call of pyglet.sprite.Sprite.
First, you can change the sprite's animation by setting its image attribute, instead of creating a new Sprite instance. Second, only change its animation when you actually need to. That is when the direction changes.
I've added a simple example (pseudo) code to roughly show what I mean.
def animation(image, da, width, height):
frame_list = [image.get_region(x=width * i, y=height * da, width=46, height=58) for i in range(22)]
image_animation = pyglet.image.Animation.from_image_sequence(frame_list, 0.10, True)

Is there a way in Python to add to an array to the next free space available? So if (0,0) has already a value, move on to the (0,1) and add the value there. I got as far as shown below, and I'm stuck now..
class Array:
def __init__(self):
self.array = [[0 for x in range(5)] for x in range(5)]
def view(self):
for x in self.array:
print(x)
def input(self):
item = input("Enter an item: ")
self.array[0][0] = item
array = Array()
array.input()
array.view()
Here is one example. I am simply running the loop 9 times. You should be able to work it into your OOP style code. I am also using pprint module from standard library as I like how it displays nested lists.
from pprint import pprint as pp
myList = [[0 for x in range(5)] for x in range(5)]
for i in range(9):
userInput = int(input("Enter an item: "))
isFound = False # This flag is used to prevent duplicate entries.
for rowIndex, row in enumerate(myList):
for colIndex, column in enumerate(row):
if column == 0 and not isFound:
myList[rowIndex][colIndex] = userInput
isFound = True
break
pp(myList)
Output after last iteration of the loop: (assuming 5 was always entered):
Enter an item: 5
[[5, 5, 5, 5, 5],
[5, 5, 5, 5, 0],
[0, 0, 0, 0, 0],
[0, 0, 0, 0, 0],
[0, 0, 0, 0, 0]]
class Array:
def __init__(self):
self.myList = [[0 for x in range(5)] for x in range(5)]

print("You will be asked to put a value, if you want to stop, press RETURN key.")
for i in range(25):

userInput = input("Enter an item: ")
isFound = False
if userInput == '':
menu()
for rowIndex, row in enumerate(self.myList):

break

I've created hangman using zelle graphics in Python. Everything is working fine and dandy, but all of a sudden i can no longer draw anything on the window?
