Hi,
Good Start!
Few things:
-- Expose the input references, so that we can decide what input axis to use, that will make the action a lot more flexible. And simply put as defaults the usuals.
-- multiplier should be set to the default value instead of using a variable , otherwise the action doesn't work if you simply drop it on a go.
-- also, you definitly can add the thrust input in this action, that will make it complete.
bye,
Jean
