This is a first tutorial of a new series where we are going to create a bot that plays the game of tetris automatically.

First we need to have the game of Tetris. We open the game of tetris on our browser. We need to use 4 Python libraries : pillow, pywin32, opencv and numpy. First we scan all the windows available using the library win32gui. On line 7 we create an emply list where we store all the name of the windows and their handle. Once we have the list of all the windows handles and their name, we can select only the window we are interested in, the one with the game.

Kwowing the position of the window, we can now take a screenshot. A screenshot is only a picture, and as we want to grab the images in realtime, we put this funciton in a loop so that we can take the entire video streaming in realtime. In case you would like to know more about the code written, watch the video tutorial where I code it all from scratch and I explain everything.

I'm learning Python and the first challenge I set myself is to program a bot for a browser game.

My script requires the input of numbers that are displayed at certain positions during the game. I do this by taking a screenshot of the displayed number and comparing it to a screenshot of the same number at the same position I saved earlier on my computer. If the screenshot and the comparison image are the same, the function returns True. Unfortunately, there are apparently some positions where the numbers are displayed with very subtle differences every time they appear.

The differences aren't noticeable with the naked eye and I can't find them even if I zoom in to see the individual pixels and compare them with each other, yet the function returns False every time I take a screenshot of the number and compare it to its comparison image. One of my ideas to solve this issue was to compare the file size of the screenshots with the comparison image's file size, but this method is not reliable because the file sizes vary too much another indication that there are indeed tiny differences every time the number is displayed.

I have considered OCR, Mean Squared Error and Structural Similarity Measure, but all of these methods are rather complex and would probably slow down the script tremendously. I would really like to find a simpler solution if possible. Please share any ideas with me you might have. Here are two screenshots of the same number at the same position at different times.

Thank you, Micka.

I just experimented with this. If I print the difference of one 20 with three other 20s, I get: 0, 0, 25, 170, 0, 25, 180, 0, 25, By comparing 34 screenshots with each individual screenshot, I found that the last number of this output is a reliable indicator if the numbers on the screenshot are the same or not.Yes, I know you all have played the Snake Game and definitely, you never wanted to lose. This is what I will be showing you all in this article on Snake Game in Python.

The first thing you will need to do in order to create games using Pygame is to install it on your systems. To do that, you can simply use the following command:. Once that is done, just import Pygame and start off with your game development. Before moving on, take a look at the Pygame functions that have been used in this Snake Game along with their descriptions.

To create the screen using Pygame, you will need to make use of the display. There is another method i. The difference is that the update method updates only the changes that are made however, if no parameters are passed, updates the complete screen but the flip method redoes the complete screen again. But when you run this code, the screen will appear, but it will immediately close as well. To fix that, you should make use of a game loop using the while loop before I actually quit the game as follows:.

When you run this code, you will see that the screen that you saw earlier does not quit and also, it returns all the actions that take place over it. I have done that using the event. Now, you have a screen to play your Snake Game, but when you try to click on the close button, the screen does not close.

This is because you have not specified that your screen should exit when you hit that close button. So now your screen is all set. The next part is to draw our snake on the screen which is covered in the following topic. To create the snake, I will first initialize a few color variables in order to color the snake, food, screen, etc. The color scheme used in Pygame is RGB i.

So our snake will actually be a rectangle. To draw rectangles in Pygame, you can make use of a function called draw. As you can see, the snakehead is created as a blue rectangle.

The next step is to get your snake moving. In this snake game, if the player hits the boundaries of the screen, then he loses. Also, make a not over here that I have removed the hardcodes and used variables instead so that it becomes easy in case you want to make any changes to the game later on.

Also, I will be making a small change wherein I will include the options to quit the game or to play again when the player loses. The following code will increase the size of our sake when it eats the food. The length of the snake is basically contained in a list and the initial size that is specified in the following code is one block.

Last but definitely not the least, you will need to display the score of the player. This function will display the length of the snake subtracted by 1 because that is the initial size of the snake. With this, we have reached the end of this article on Snake Game in Python.

I hope you are clear with all that has been shared with you in this article. Make sure you practice as much as possible and revert your experience. Got a question for us? Already have an account?

Then, however, somewhat mysteriously, GTA V was completely removed from Universe with no explanation whatsoever.

I gave up and forgot about it for a while, but the idea still seemed exciting. Finally, I decided to put some more mental energy into it, and questioned whether or not I even needed Open AI at all for a task like this. Sure, it's nice for simpler games that can be run en masse, so you can train thousands of iterations in moments, but, with something like GTA V, this is really not going to be much of an option anyway.

Just in case it's not totally obvious, why GTA V? At least for me, Grand Theft Auto 5 is a great environment to practice in for a variety of reasons. It's an open world with endless things you can do, but let's consider even just a simple one: Self-driving cars. With GTA V, we can use mods to control the time of day, weather, traffic, speeds, what happens when we crash It's just a completely customize-able environment. Some of my tutorials are planned fully, others sort of, and some not at all.

This is not planned at all, and is going to be me working through this problem.

I realize not everyone has Grand Theft Auto 5, but it is my expectation that you have SOME similar games to do the tasks we're going to be working on, and that this method can be done on a variety of games. Because you may have to translate some things and tweak to get things working on your end, this is probably not going to be a beginner-friendly series.

My initial goal is to just create a sort of self-driving car. Any game with lanes and cars should be just fine for you to follow along. The method I will use to access the game should be do-able on almost any game. A simpler game will likely be much more simple of a task too. Things like sun glare in GTA V will make computer vision only much more challenging, but also more realistic. I may also try other games with this method, since I also think we can teach an AI to play games by simply showing it how to play for a bit, using a Convolutional Neural Network on that information, and then letting the AI poke around.

This is already enough for more rudimentary tasks, but what about for something like deep learning? Really the only extra thing we might want is something that can also log various events from the game world. That said, since most games are played almost completely visually, we can handle for that already, and we can also track mouse position and key presses, allowing us to engage in deep learning. I doubt this will be sunshine and rainbows, but I think it's at least possible, and will make for a great, or at least interesting, project.

My main concern is processing everything fast enough, but I think we can do it, and it's at least worth a shot. So this is quite a large project, if we don't break it down, and take some baby-steps, we're going to be overwhelmed.

The way I see it, we need to try to do the bare minimum first. Thus, the initial goals are:. Alright, so step 1, how should we actually access our screen? I am only certain it's been done, but I don't really know how. For this, I take to Google!

More fighting. The dtype should be string, not what appears to be a variable name that's obviously not defined. Did this person run the code?There are some that demonize it. And some whose utopian views claim that AI could almost be God-like in helping humanity. Whichever side your views tilt, AI is here to stay. They have been the go-to testbed for AI. Game programmers used to use heuristic if-then-else type decisions to make educated guesses.

We saw this in the earliest arcade videos games such as Pong and PacMan. This trend was the norm for a very long time. Game developers then tried to mimic how humans would play a game, and modeled human intelligence in a game bot. The team at DeepMind did this by generalizing and modeling intelligence to solve any Atari game thrown at it.

The game bot used deep learning neural networks that would have no game-specific knowledge. They beat the game based on the pixels they saw on screen and their knowledge of the game controls. However, parts of DeepMind are still not open-sourced as Google uses it to beat competition.

It seeks to democratize AI by making it accessible to all. OpenAI Gym provides a simple interface for interacting with and managing any arbitrary dynamic environment. OpenAI Universe is a platform that lets you build a bot and test it out. There are thousands of environments. They range from classic Atari games, Minecraft, and Grand Theft Auto, to protein fold simulations that can cure cancer.

You can create a bot and run it in any environment using only a few lines of Python code. This is too awesome not to try!

Day 22: How to build an AI Game Bot using OpenAI Gym and Universe

In this post we will add a mouse controller as well as handle basic bot logic to get the bot actually solve some of the beginner puzzles. For controls, as before in the Burrito Bison bot, here we only need the mouse. In this case the bot will rely on the human to set up the game level, handle game UIs, while bot itself will be responsible only for finding the right solution and moving game pieces to the target cells.

We start with the basic outline:. Pynput would be able to move the mouse in a single frame just by changing mouse. And in a way that makes sense. Human mouse movements normally take several hundred milliseconds, not under 1ms.

The second necessary operation is mouse dragging, which means pushing the left mouse button down, moving the mouse to the right position and releasing the left mouse button.

The bot component will need to communicate between the other 3 component. For bot logic there are 2 necessary steps:. Then we need to a way feed information to Solver.

So we first will need to map vision information into structures that Solver can understand. However, vision information returns Cell x, y, width, height, content. So we need to map that as well:. We can just pass that along to the Solver unchanged for now, but will likely have to change it once constraints are implemented. Now we only need to find which available pieces to take from which cell, and move those to respective target cells.

As for handling coordinates, one thing to not forget is that coordinates point to the top left corner of the corner, and are not always absolute in relation to the OS screen. Top left corner of the piece is also not always usable - the game may not respond.

However, if we target the center of the cell - that works reliably. Now we have all the tools for the bot to solve basic puzzles of Puzlogic.
