There are parts of the extension registration process which rely on the
`info` field being non-null, even for block separators. At one point
during development I broke that, so here's a test to hopefully prevent
someone else from getting bitten by the same thing.
These compatibility changes:
- Use runtime.currentMSecs for the Clock timer "now" value
- Start executing hats before other threads change values
- Update test and fixtures to work with earlier hat execution
- Add test for hat execution block order
- Creating Boost._colorBucket will contains BoostColorSampleSize-amount of samples
- Boost._onMessage administers the _colorBucket and assigns Boost._sensors.color a value if all items in the bucket match.
E.g. if BoostColorSampleSize is set to 3, three continuous readings of the same color are required for the color to be detected by scratch-vm.
- Renamed BoostOutputCommandFeedback to BoostPortFeedback and its values for brevity
- Removed buf2hex-function
- Removed BoostMotor._pendingPositionOrigin (unused)
- Removed Boost._led (unused)
- Simplified _onMessage-handling of BoostPortFeedback-messages
- motorOnForRotation() now returns a Promise.all rather than a single promise. This solves two bugs:
-- when running turn ABCD for 3 rotations without motors connected to CD, the block would finish yielding immediately.
-- when running turn C for X rotations without a motor connected to C, the motor would never finish yielding.
- BoostMotor-class now has pendingPositionDestination, the rotation-equivalent of pendingTimeout, that stores a destination the motor should reach. When using setMotorPower() or setMotorDirection() while a motorOnForRotation()-block is running, a new motorOnForRotation()-command will be run for the remaining amount of degrees but with new power/direction, cancelling the old command.
- BoostMotor._status is only affected by feedback from the hub.
- setMotorPower() and setMotorDirection() no longer yields, since they just set state.
From design meeting regarding block design:
- Renamed all motors-label to ABCD.
- Added 'AB' motor label to address built-in motor pair.
- use the word direction in the setMotorDirection-block
- moved argument label in motor position reporter
- changed wording of color-sensing block.
- removed isTilted-boolean reporter
- removed changeLightHueBy-block
- fixed pingDevice-function bug.
