This pattern is a still a stub.

The goal to try and move a game element from one position in the game to another. Board games such as Backgammon and Ludo and all sports Race s from the 100 Meter Dash to marathons to horse Races are examples of Traverse used together with Race.

Examples

Example: Moving one's pawn to the opposite end of the board is a Traverse goal in Chess.

Example: Platform games such as those in the Mario or Super Monkey Ball seriescan be defined as having Traverse goals of going from the beginning of a level to the end.

Left 4 Dead series Assassin's Creed series

RoboRally

Using the pattern

The three main considerations when designing Traverse goals are where the goal area is, how one can move to get there, and the layout of the actual game space that has to be moved through to get there.

The simplest way to define goal areas is to make use of Goal Points.

The game space can either only allow one specific path to be followed (having one Goal Point at the end location), as in Snake s & Ladders (players do not have a choice of how to move although the ladders and snakes provide shortcuts and returns to earlier places), or allow players to choose between different paths (having at least one Goal Point at the end location and possibly intermediate Goal Points that have to be visited). The latter allow players to make plans depending on what Strategic Location s exist as well as what Enemies and Obstacles exist, for example, letting players choose between Evade and Overcome goals.

The means of Movement players have can be linked to Risk/Reward Tradeoff s as well as provide different players with different routes to advance on by the use of Privileged Movement. The use of intermediate Goal Points can create a Hierarchy of Goals consisting of various Traverse Goals. The Goal Points can be used to support Safe Havens, and their introductionallows players to get relief from Tension and promotes Stimulated Planning for the next phase of Movement. By making the Goal Point initially an Inaccessible Area, the Traverse goal can be the main goal of a Hierarchy of Goals, where several other sorts of activity besides Movement need to be performed. When the reason for a Traverse goal is to achieve Area Control of the Goal Point, the Strategic Location of the Goal Point needs to be considered, as this will modulate the willingness of players to strive for the goal.

Common variants of Traverse include Delivery, where the goal objects to be moved are not the game elements doing the movement, and Herd, where Indirect Control and Units are used for moving the goal objects. Herd can also be a Preventing Goal of Traverse when a player's movement can be affected by other players' actions. By giving players Imperfect Information about the Game World between the starting point and the end point, Traverse goals can becomes goals of Exploration or Reconnaissance.

If some form of Limited Resource is consumed by Movement, the Right Level of Complexity of a Traverse goal is affected as choices of which terrain is traversed and what movement styles to employ become important. Racing games usually provide some form of Charger or Pick-Ups in specific Resource Locations and, in Races, force players to make Risk/Reward choices between saving time and risking not having enough Resources or losing time but having Resources.

When the player has Freedom of Choice regarding Movement in a Traverse Goal, the goal may require that players are given information about where the Goal Point is located. Game State Overview can be used to support players with this information as can Traces, which may be seen as Supporting Goals of shorter and easier Traverse goals.

Traverse goals can be used to modulate the likelihood for players to attempt different goals in Selectable Sets of Goals by having the Traverse goals as subgoals that have to be performed before individual goals.

The presence of Save Points creates Traverse goalsthat break the Consistent Reality Logic.

Narrative Aspects

As Traverse depends on players moving from one area within a Game World to the other, the completion of the goal guarantees that the player has changed environment. This can be used to set up progression in Predetermined Story Structures.

Consequences

Traverse goals gives players clear goals related to Movement and achieving Contact with a specific game object or game area. They most often allows players to judge their local progress by their position in the game space, but while this may seem to remove the need of Progress Indicators if the end point is known - since the positions of player's game elements provide a diegetic measure of progress - it does not necessarily provide good overviews. Making players think about how they should move their Focus Loci or other game elements to succeeded with the Traverse goals is likely to support Spatial Engrossment.

While Traverse goals are often placed in games to create Races, the presence of other types of Traverse goals can make Races emerge if two or more Agents decide to strive for the Traverse goals (an example of this can be found in the Civilization series where different players may be rushing to find as many ruins as possible before other players do).

Try to performing Aim & Shoot actions while also trying to achieve Traverse goals is more difficult than doing just one.
