''Game systems where a player's actions can be initiated by either that player or the system, or where the execution of the actions are performed together.''

Letting players perform actions is vital in most games but in some cases game designers may wish to influence these actions during gameplay. This can be done by the system activating the actions irrespectively of players' intentions or by letting the execution of an action by actively modified by the system as it is being executed. Games that do either of these two things have [[Player/System Action Composites]].

=== Examples ===
The auto-aim functionality found in games such as the [[Grand Theft Auto series|Grand Theft Auto]] and the [[Halo series|Halo]] are examples of [[Player/System Action Composites]]. Likewise, the possibility for players to write code or scripts in [[DragonMud]], [[Ultima Online]], and [[World of Warcraft]] that can make their characters perform actions are examples of [[Player/System Action Composites]]. 

== Using the pattern ==
[[Player/System Action Composites]] can either be created by letting actions that execute mechanically once activated be possible to be activated both by a player or the game system, or let input from both affect the execution of an action. 

An important aspect of the latter is to make sure that the system part actually differs from "normal" execution of the action; this is most easily done by letting others not have the pattern or making the pattern active due to [[Power-Ups]]; here, the pattern is created by the combination of [[Power-Ups]] and [[Improved Abilities]]. Independent of type, they are most easily created through [[Automated Responses]]. Sometimes this is created through letting the [[Skills]] or [[Characters]] affect the action, i.e. using [[Player/Character Skill Composites]] together with [[Automated Responses]] (or, in more complex cases, [[Enforced Agent Behavior]]) to instantiate the pattern. 

Supporting [[Player Augmentations]] can allow players to choose to have the pattern or not independent of gameplay events. Similarly, [[Player/System Action Composites]] can be modulates by having them as [[Optional Rules]]; this provides a way for players to select their [[Difficulty Levels]].

== Consequences ==
[[Player/System Action Composites]] quite naturally modify patterns related to actions modified by the pattern, of which [[Combat]] and [[Movement]] are perhaps the most natural choices. 

The use of the pattern affects both [[Performance Uncertainty]] and [[Player Unpredictability]], typically in making them less uncertain or unpredictable. It can both provide [[Player Agency]] and remove it, depending on how players perceive the effect of the system initiating or modifying the execution of actions.
