What is AI in Gaming?

AI in gaming refers to excellent game experiences which is more-
1. Responsive
2. Adaptive
3. Challenging
Artificial Intelligence brings revolution in player experience, cost reduction, better
performance in gaming sector.

AI ENEMY AI COMPANION
AI companions provide friendly faces in
a hostile environment. They assist in
navigation, puzzle-solving, and combat.
They alleviate loneliness.
Well-implemented enemy AI is
characterized by the believability of
opposing NPC movement, how they
converse, behave, and react to any
given situation created by the player.

AI IN GAME-LEVEL GENERATION

One of the primary aims of play, aside
from staying alive, building stuff and
acquiring goods, is to explore as many
of the over 18 quintillion randomly
generated planets as you like.
Open world? Try open universe.

Every interaction opens up a series
of possible improvements.
These actions are somewhat
randomized by design so the AI
doesn't start to feel predictable.

Mercury is the closest planet to the Sun and
the smallest one in the Solar System—it’s only
a bit larger than our Moon. The planet’s name
has nothing to do with the liquid metal since it
was named after the Roman messenger

STEERING BEHAVIORS -
- GAME TREE CALCULATION
- BOARD EVALUATION

BOARD GAME
GAME TREE CALCULATION
MINIMAX MONTE-CARLO
TREE SEARCH

MINIMAX
In Minimax the two players are
called maximizer and minimizer. The
maximizer tries to get the highest
score possible while the minimizer
tries to do the opposite and get the
lowest score possible.

METHODS FOR CALCULATION-
EASING
ALPHA-BETA
PRUNING
NULL MOVE
HEURISTIC
QUIESCENCE
SEARCH

ALPHA-BETA PRUNING
Alpha is the best value that the maximizer currently
can guarantee at that level or above.
Beta is the best value that the minimizer currently
can guarantee at that level or above.
WHEN ALPHA >= BETA PRUNE REST OF THE TREE
METHODS FOR CALCULATION-
EASING

NULL MOVE HEURISTIC
The null-move heuristic is a heuristic technique
used to enhance the speed of the alpha-beta
pruning algorithm.
Game state is evaluated by assuming one player
“passes” a move.
METHODS FOR CALCULATION-
EASING

QUIESCENCE SEARCH
The purpose of this search is to only evaluate
"quiet" positions, or positions where there are no
winning tactical moves to be made.

VIDEO GAME
STEERING BEHAVIOR
SEEK PATH
FOLLOWING

SEEK
The addition of steering
forces to the character
every frame makes it
smoothly adjust its velocity,
avoiding sudden route
changes.

PATH FOLLOWING
The path following steering
refers to the character
constantly adjusting its
direction to catch the
target.

FINITE STATE MACHINE

Artificial neural networks (NNs) are structures akin to human brains that
can learn various features from training data. Given a large set of data,
NNs are capable of modeling very complex real-world and game
scenarios. NNs overcome some of the shortcomings of classic AI
techniques in game agent design. Furthermore, NNs are self-adaptive
and adapt well to game environments that change in real-time.
Advantage => Too smart agent
Disadvantage => Too smart agent

FUTURE OF AI IN GAMING
04
What else can be done?

Cloud-Based Gaming
with AI
Cloud gaming is a technology that streams games across the Internet rather than
requiring the user to download and install the game.

Voice or Audio
Recognition-Based Games
With voice recognition in gaming, the user can control the gaming gestures,
monitor the controls, and even side-line the role of a controller.

Wearable Support
Gaming and VR Gaming
Experiential games like AR, VR and MR, making them more realistic and
progressive towards entertainment.

Blockchain-Based
Gaming
Blockchain-based gaming indicates that both, gamers and developers need to
get together on the blockchain platform to play these games

Improved Mobile
Gaming Experience
Mobile gaming have been focusing on and developing devices compatible with
high resolution and heavy graphics.

CAN an AI develop an AI based game
?
