Game elements, or distinct parts of game worlds, that guide players to locations in the environment that influence gameplay.

Players may have difficulties realizing where interesting gameplay possibilities exist in games. When game designers wish to make it easier, but not completely obvious, to locate these they can make use of Traces.

Examples

A literal use of Traces are found in many first-person shooters, e.g. Duke Nukem 3D, by avatars leaving footprints after going through water, blood, etc. This can be used by players (and sometimes the AI) to track each other. See the page for footprints on Giant Bomb for more examples^[1].

Both Half-Life 2 and the Left 4 Dead series provide Traces in their games that show what people of those worlds previously have done in their struggles, and players can make use of these to find locations where they can replenish their supplies.

Where to go next in race events in the Grand Theft Auto series are shown through non-diegetic pillars of light that can be seen from far away.

The difficulties of navigating the mazes in certain text-based games, e.g. the Zork series, required players to create their own Traces in the form of breadcrumb trails consisting of dropped game items.

Using the pattern

Check Points

The functional nature of Traces in games can be separated into two general classes: those that cannot be manipulated by the players and those that can. The first class provides players with information about what previous actions have happened before and during the gameplay. Those generated before the gameplay typically provide Clues or help unfold Narration Structures by being part of Environmental Storytelling, while those generated during the gameplay can be Traces of other players and often disappear after a certain Time Limits.

Traces which consist of game elements that can be manipulated by the players create additional tactics in games. Players may be able to move the elements to set-up false Traces, i. e. Red Herrings that may led to Deadly Traps, or make Tradeoff decision whether to spend time hiding their own Traces or not.

Traces can also occur through the lack of game elements, e. g.Pick-Ups or Enemies. In these cases the configuration of game elementscan be seen as negative Traces, i. e. the Traces can only be detected because something is lacking or has been changed due to the actions of the players or game events.

Diegetically Outstanding Features, Environmental Storytelling, Geospatial Game Widgets, Landmarks, Pick-Ups, Props, Switches

Traces are commonly used to indicate the presence and location of Enemies, Resource Sources, and Traps. While Traces in these cases lead players to specific points in Game Worlds or Levels, they can also support the Movement required for accomplishing Traverse and Exploration goals; for Reconnaissance goals, the detection of Traces can instead be the primary subgoal.

While game designers can add Traces to games that exist at the start of game instances, they may also be designed to occur as consequences of action and events (the footprints left after entering water in Duke Nukem 3D is an example of this). However, players may create Traces themselves if they can drop Game Items, which can be used to support Game World Navigation , and unless Pick-Ups are instantly respawn the absence of them from locations in games can be Traces also.

Diegetic Aspects

Traces can often be constructed to maintain games' Thematic Consistency through using Environmental Storytelling, Landmarks, and Props so that they are presented as effects of previous events. Diegetically Outstanding Features and Pick-Ups can be used when these are not sufficiently obvious, but can break the consistency if overused. Geospatial Game Widgets are guaranteed to break Thematic Consistency but can make the Traces very obvious. Cutscenes can be used for greater control of how the Traces are to be presented.

Narrative Aspects

Even if the Traces pattern relates primarily to how players can be informed about previous and potentially future gameplay events, it can also support Narration Structures. This is more or less a given when they are created as part of Environmental Storytelling.

Traces may be especially appropriate for those Narration Structures using a Detective Structure since these rely on players slowly being told the story from one perspective.

Consequences

Traces are either built from Diegetically Outstanding Features or become this through how they attract attention, or both. By directing players towards points of interest in Game Worlds or Levels where danger or Rewards can be found there, Traces provides Clues that can give rise to Anticipation and Tension in games. However, not all Traces lead to what they seem; these are instead Red Herrings which promise Illusionary Rewards. Being able to both give players information and misinformation about future gameplay, Traces are able to modulate the difficulty in games to have the right level of Challenging Gameplay.

Traces modulates Game World Navigation and Movement since they affect where players want to move, especially when they are used to indicate the route for Traverse goals or give Clues for Exploration goals. When the Traces are created during gameplay as effects of actions and events, Traces can support players in their Tactical Planning.
