BindActionToInputTypes

BindAction binds functionToBind to input events such as key presses, mouse movement, or controller input. The specific input types the engine listens for are listed as parameters of BindAction. Whenever a player uses any of these input types, the Roblox engine calls “functionToBind”. BindAction sets the priorityLevel via Enum/ContextActionPriority to Default.Value, which is 2000. Use ContextActionService/GetButton to control the priority of bound events.

In addition to input types, BindAction has a createTouchButton parameter. When this is set to true it creates an ImageButton on any device with a touchscreen. A ScreenGui is also created to put the context buttons into named ContextActionGui and is parented to PlayerGui. The created ImageButton is parented to this ContextActionGui. GetButton can be used to retrieve the button that was created.

If an input has more than one function bound to it, each function will be placed on a stack. A stack obeys the principle of last in first out. So the first object placed on the stack will be on the top. The next object placed on the stack becomes the top and the previous object moves one position down (like a stack of books). When the input is triggered, the function at the top of the stack is called. If the function returns Enum.ContextActionResult.Pass this will continue down the stack. To remove a function from being called by all input that it was bound by use ContextActionService/UnbindAction.

BindAction allows control over whether or not a bound action should be processed by other actions on the stack using Enum/ContextActionResult. If Enum.ContextActionResult.Pass is returned in the callback function, every action below it in the stack (last function called gets executed first) will get a chance to process it. Anything other than Pass will be treated as Enum.ContextActionResult.Sink, including nil. It will also sink if the callback is yielded.
