Hi, can you put the html container site you tested with here? Makes it easier for me and others to test. Thanks. :) |

Here's a live version https://libgdx2.v22018086706171227.nicesrv.de/ |
# Conflicts: # backends/gdx-backends-gwt/src/com/badlogic/gdx/backends/gwt/GwtInput.java

Is there a specific reason why this doesn't get merged? |

With the feature policy, developers can allow and disallow some web browser features in iframes. If the game wants to access a disallowed feature, an error is thrown. This happens for example on itch.io. See for example the game of @MrStahlfelge for the game jam https://mrstahlfelge.itch.io/gdxjam1908. Make sure to use chrome. There will be an error in the console
Uncaught (in promise) DOMException: Failed to construct 'Accelerometer': Access to sensor features is disallowed by feature policyThis PR adds a check whether the feature, in this case accelerometer, is allowed. If not isPeripheralAvailable returns false and the setupAccelerometer method wont get called.
