Depends on:
This PR simply handles relative mouse and keyboard events in the
SDL_EventFilter
i.e.HandleEventFromFilter
.This works because SDL queries raw mouse and keyboard inputs on a separate thread. Our
SDL_EventFilter
will intercept those events before they are pushed to the internal SDL queue, handle them, and then request SDL to drop them.Testing
Apply the diff and toggle relative mouse mode in
TestSceneInputManger
.This isn't a perfect simulation of
SDL_PumpEvents()
lag, but it shows the async input in action.
