The XRInputSourceArray
interface's entries()
method returns a JavaScript iterator
which can then be used to iterate over the key/value pairs in the input source array. Each item in the array is an XRInputSource
object.
Most frequently, you will use this in tandem with statements such as for...of
.
Syntax
let inputSourceIterator = xrInputSourceArray.entries(); for (let entry of xrInputSourceArray.entries()) { /* ... */ }
Parameters
None.
Return value
An iterator
which can be used to walk through the list of XRInputSource
objects included in the input source array.
Examples
This example snippet gets the list of inputs for a session and tries to handle each type of input device it supports using.
let sources = xrSession.inputSources; for (let input of sources.entries()) { if (input.gamepad) { checkGamepad(input.gamepad); } else { if (input.targetRayMode === "tracked-pointer" && input.handedness === player.handedness) { /* Handle main hand controller */ handleMainHandInput(input); } else { /* Handle other inputs */ } } }
For each input in the llist, gamepad inputs are dispatched to a checkGamepad()
with the input's Gamepad
object, taken from its gamepad
property, as an input
For other devices, we look for tracked-pointer
devices in the player's main hand, dispatching those to a handleMainHandInput()
method.
