Interaction is a gameplay mechanic that allows players to perform certain actions with a single multi-purpose button.
Battlefield: Bad CompanyEdit
Beginning with Battlefield: Bad Company, the Gold Rush game mode requires attackers to place explosive charges as one means of destroying enemy objectives, and defenders to disarm any such charges. Using a dedicated button allows the player to perform all other actions (combat, movement) while (dis)arming the charge.
Battlefield 4 introduces many interactive objects in multiplayer maps as part of Levolution features, serving functions such as opening/closing gates, moving elevators, and starting portable generators. The various expansion packs offer other interactive features such as sealing blast doors or performing operational tests of prototype equipment. A number of other non-interactive objects will react to damage or drone activity, such as releasing blinding gas, or sounding an alert.
Battlefield 1 expands on interactivity with doors by allowing sprinting players to burst through closed doors.
Contextual actions may be available to a player under certain conditions.
Beginning with Battlefield 3, the Commo Rose offers a contextual action when aimed at a teammate. Players may announce their ability to provide a support action or demand it of others, or request a ride from a friendly vehicle. Explosives can be defused by anyone carrying a Repair Tool or EOD Bot.
Deployed gadgets such as the Radio Beacon can be retrieved by their owner by using the button.
