Strategies we attempt to survey the various roles CI could play in a The strategies involved in TD games can be varied de- TD game, pointing out related research that has been done pending on the elements of the game.
Different types of on games from other genres. Overall however, the B. Map Generation strategies can be grouped into two main problem domains: The map is one of the core features of a TD game, and one resource allocation and unit placement.
The resource al- of the main drivers of challenge and sources of differentiation location strategies usually involve choices between buying between levels.
While it is common to buy cheap discover. In light of this, automatic map generation would be towers early on, one useful strategy is to buy minimal cheap a major advantage for a TD game. Map generation could be towers and save for a powerful tower to place at a strategic done both offline, when the game is developed, or online, on location on the map. It can be tempting to forget to allocate resources to Map generation could be done in more or less simplistic towers that target these units, and not have enough to counter fashions, for example through starting with a straight path waves of these creeps when they appear.
While it is useful to have a a pathfinding algorithm. However, such methods are not strong front-line, and destroy creeps as they are deployed at very controllable, meaning that there is no good way of the start position, fast creeps can potentially run straight past ensuring that the generated map is of the right difficulty, the front-line and additional towers further along the path are that it promotes the right kinds of towers and strategies, or needed to stop this.
A CI-based alternative is the search-based paradigm, for human game play. This is discussed further in the next where a stochastic optimization algorithm such as an evo- section. In case D. Creep strategy of a tower defence game, one would start with finding a One possible change to the TD game that the CI commu- representation for the map, and an operationalization of some nity can make, is to make the deployment of creeps dynamic desirable criteria for that map.
When using a the map should have the right level of challenge, that it dynamic creep deployment, agents could be created to play should promote combinations between certain towers, force both sides of the TD game. This would require a method a particular strategy etc. Once these criteria are formalized of restricting the way creeps can be deployed.
One possible as a fitness function, maps can be evolved that satisfy them method of this is to treat creeps in a similar way to towers, as well as possible given the game and map representation. The further a creep progresses along the map path, evolve maps for the real-time strategy game StarCraft [7]. These resources can then be used to In this experiment, the bases and resources on the maps purchase more creeps, with higher costs for stronger, faster were represented directly as x, y positions, whereas the and tougher creeps.
Several fitness By changing the game in this manner, it is also possible functions, having to do with the fairness of the maps and their for human players to play both sides of the game, as either suitability for using advanced strategies e.
This provides many interesting research choke points were defined, and combined using a multi- possibilities, as well as a more challenging game for human objective evolutionary algorithm. A similar approach could players. Play could either be done in real time, or turn based.
Game element generation map representation and evaluation functions are defined. In addition to automatic map generation, there also exists C. AI for playing the game potential to change the dynamics of the game itself. Some of these are easily with research performed on different ways to deploy units exchangeable, such as changing the attributes towers and to on a map. Miles, Avery and Louis [8], [9] co-evolve the corresponding creeps are allowed to have.
Finding a way to strategic deployment of units on an RTS grid using Influence automatically choose and then balance these attributes could Maps. Other research such as that by Weber and Mateas [10] create another method of continuing game-play for a TD focus on methods to automate the build order when to build game.
These problems are also relevant to TD game prospects. The generation of elements and game AI games, where the pertinent questions are where to build what could also be combined to automatically adjust the difficulty towers and when. The TD map is also usually represented in of the game. This is discussed further in the next section. Dynamic difficulty adjustment and Player Modelling turn-based games. Game balancing, or dynamic difficulty adjustment DDA , The resource allocation area is another interesting research refers to the automatic adjustment of games to fit the skill topic.
Research on using CI techniques for a turn-based level of the player [14]. This is motivated by the ever- resource allocation game has been done by Johnson et. As a large component costs of developing top-quality games. Simply put, a single of the TD strategy is through resource allocation, it would game will need to appeal to a much larger range of different be interesting to see if similar techniques could be applied players and different playing styles now than it did back here.
The DDA answer to this creeps are deployed. Sometimes some interesting strategy development. It could be argued that the less obvious the adjustments are to the player, the better. While difficulty adjustment could be implemented in a simplistic manner in a TD game, e. A similar suggestion for platform games is made in [15]. Another method of adjusting the difficulty is to create a Fig. Work by Avery is the tower repository, from which towers can be bought for placement on and Michalewicz [16] follows this method, and showed the map or discarded.
Using this method in TD games could increase the enjoyment, when players know the game they are playing is tailored to their individual players, allowing the creation of levels that elicit game playing experience. The grid nature of the TD game desired affects in particular players [19]. Infinite TD is a prototype tower defence game aiming to A further refinement that CI techniques make possible demonstrate how CI and other adaptive techniques can be is to step away from a one-dimensional view of player used to improve this genre of games.
Instead of taking an performance, and instead see performance as having sev- existing TD game and modifying it, the decision was made eral components and adaptation to these as positioning the to design the game from the ground up around adaptive challenge profile in a multidimensional space. For example, mechanisms. This section describes the overall design and a particular player might be good at placing the offensive adaptive features at the current state of the game; the game towers for maximum effect, not very adept at using the sup- is currently being developed, with a target of being released porting towers, make good investment decisions i.
These relative strengths A. Game Design and weaknesses can be measured and used to inform a In some senses, Infinite TD is an utterly conventional fitness function, so that content can be evolved that plays the tower defence game. The goal is to survive as many waves of unique strengths and weaknesses of the player. This way, an creeps as possible. The creeps travel along and tower types. This means end of the path, the player loses a life. To defend against adapting the game not only to the skills of players, but the creeps, the player can purchase towers and place them also to their preferences.
For this, player experience models strategically on the sides of the path. The price of a tower need to be created, mapping features of the game and depends on its capabilities, which can vary along dimensions gameplay to predicted player experience. Such models can such as range, firing speed, poison effect etc. Enter the email address you signed up with and we'll email you a reset link. Need an account? Click here to sign up.
