Introduction to Game Programming Introductory stuff Look at a game console: PS2 Some Techniques (Cheats?) The latest book from a very famous author finally. DM Computer Game Programming II: AI. Rolf Fagerberg. Fall 1 Acceleration techniques (culling, level of detail, spatial data structures) [Course I]. Game AI is as old as AI itself, but over the last decade the field has seen mas- sive expansion . handful of programming exercises. For your learning intersects with both AI and CI, and many techniques could be said to be part of either.

El Sayed - Eng. E-mail: drsaadz yahoo. Abstract In this study we try to show, assign and compare the relation between the AI Artificial Intelligence techniques and its usage and implementation in the Game Programming field. The comparison also done to show the difference between the academic AI techniques and how they were changed and adapted to be compatible with the Game Programming needs as it mainly depend on the propose it will be used in. Then we show the most popular technique used in Game Programming field that is known as common techniques. Finally we will give some instances of the most popular computer games and the corresponding AI technique it use in it application.

AI agent in a dynamic virtual world.

These sensors will receive real-time data from the physics engine therefore Training the neural network for basic real-time giving the agent a sense of awareness about its surrounding pathfinding first required it to learn to i head in direction environment. Therefore the first step will be to see if the NN can learn these two tasks separately and then finally learn both of them combined.

This is achieved by rewarding AI agents for following various rules that the user specifies at different 20 time intervals. Then the AI agents are then ranked 10 according to their respective scores, with the top ranking 0 0 agents putting a mixture of their weights into a lower Thousands ranking agent.

This is analogous to the evolutionary Neurons survival of the fittest model. Figure 1. As shown in figure 1.

Once linked a number of graphical how many neurons a NN is composed of, to thousands of user interfaces GUI were implemented that allow the user AI agents being able to use a trained NN at the same time. This time The user is given real-time control over all the GA the inputs were the sensors and the output was the same as parameters thus giving the user huge scope to dynamically before.

These parameters are the selection function, the crossover The next test was to see if a NN could learn to head in the function, mutation probability, evolution time and all the direction of a goal and avoid obstacles that may litter the elements concerned with the rank function.

This facilitates path. The AI agent also has no prior knowledge of the map evolution in stages of difficulty, by introducing more and reacts purely on what it senses in real-time.

The inputs elements as the AI agent learns previous ones, thus provided to the NN were relative position to the goal and gradually evolving to a more complex behaviour. This proved to be very difficult for the NN to learn so much so that a 2. Another major change over the inputs to each AI agents NN and its activation that was integrated into the system was the ability to run function.

It also offers the user the facility to bias certain the simulation in discreet intervals. This meant at the end of inputs thus decreasing the search space for the NN initially, each interval the agents were reset to their original position and then gradually removing the bias values at later stages and orientation. This again facilitates evolution through different stages of difficulty. A set of custom maps were also created to facilitate training the AI agents to learn the basic components of real-time pathfinding.

The idea here is to have an AI agent relentlessly pursues a dynamic object around an obstacle free space.

Therefore the agent will decide which way to move via a NN that takes the relative position of the goal as its input. The NN has three outputs which are turn left, move forward and turn right respectively. The output with the strongest signal will be selected for the next move. This was learned with ease by the AI agents by scoring them for Figure 3.

An interesting result however is the variety in the solutions the GA produces. This is shown in figure 3. These maps contain sets of parallel to the same goal. Figure 3. Each bot starts at the left side of the map S and has to make its way to the goal on the right G. This finally produced AI agents that would head towards a goal and avoid obstacles on the way.
