The action of moving game elements in game worlds.

This pattern is a still a stub.

Movement of game elements is a common action in games that have a Game World or board. Movement allows players to try and move game elements into favorable positions as well as control or explore the game area.

Examples

Example: Racing games such as F-Zero GX and Mario Kart: Double Dash!! have movement as the primary activity in the game.

Example: With the exception of the value of kings and the ability of pawns to become queens, different Movement abilities are what distinguish different types of pieces in Chess.

Example: Spacewar and Asteroids both allow players to move spaceships by rotation and thrust in the spaceships' direction. However, they also allow players to escape dangerous situations by providing a limited number of hyperjumps that place the spaceship in a random location.

Using the pattern

Deciding how game elements can perform Movement depends on how Game Worlds have been created and the intended differences between game elements. Diegetically Tangible Game Items, Environmental Effects, Inaccessible Areas, Obstacles, Pick-Ups, Traps, and Warp Zones in Game Worlds all modulate Movement and can be used as the starting points for various designs of Privileged Movement and Movement Limitations. Even so, the easiest form of Privileged Movement for one game element compared to other game elements is the ability to move faster.

The difficulty of Movement is connected to the complexity of the movement and the different ways one can move. The more degrees of freedom of movement a player has, up to the maximum of six (three absolute and three rotational), the more the complexity of the Movement is increased. Further complications to Movement occur through the introduction of acceleration, deceleration, momentum, turn radii, dislocated centers of gravity, articulated vehicles, fuel Resources, Line of Sight, and vehicles with complex forms of locomotion.

These can be used to create both Challenging and Complex Gameplay, but this can be further refined in computer-based games through Player/System Skill Composites in which the computer helps calculating routes or providing Game State Overviews of the relevant factors.

So, finding the Right Level of Difficulty for Movement lies in finding a balance between the Right Level of Complexity for the Movement and the intended Freedom of Choice the players should have when moving.

Movement can be used to create Orthogonal Unit Differentiation by either giving Units some form ofPrivileged Movement or imposing some form of Movement Limitation on the units.

In Turn-Based Games, the typical way of instantiating Movement is through randomizing how far players can move, giving players Budgeted Action Points that can be spent (possible not only) on Movement, or a combination of both.

Consequences

Movement is a basic way of creating Freedom of Choice in games and both affects the Avatars, Units, or Enemies given the ability to move and the Game Worlds they can move within. It is a prerequisite for many actions and goals, e.g. Capture, Collecting, Delivery, Evade, Exploration, Herd, Races, Stealth, and Traverse as as well as modulating how Aim & Shoot can be done. Construction can also be an effect of Movement when this supports other game elements being pushed around. While all intentional Movement in Game Worlds requires Game World Navigation when this is supported through Goal Points showing intermediate target locations, the Movement done to reach these makes them act as Progress Indicators. As soon as players need to consider their own acceleration or speed, or the movement of other game elements, Movement requires Tactical Planning.

Movement does not always offer Spatial Engrossment but is more likely to do so in Real-Time Games since this makes the the Movement into Maneuvering. In contrast, Movement in Turn-Based Games can give rise to Puzzle Solving, e.g. games that require players to move between many interconnected places give rise to Traveling Salesman's problems (see Ricochet Robots and Sokoban for two Turn-Based Games that can create Spatial Engrossment even so due to focusing completely on Movement). Puzzle Solving (and through that also Tactical Planning) regarding Movement can also occur in any game where Movement is used to succeed with goals to Capture something.

Movement of game elements, usually Obstacles, that are not under the control of any players are can be examples of Ultra-Powerful Events that require Movement or Maneuvering from the players in response, for example to avoid Damage or to be able to complete Aim & Shoot actions.
