How do I share with you? Their model is an underwater ROV. The handle keys work fine, the ROV moves as it should with the defined handle keys. They would like to add an emitter so when they press the space bar, it looks like sonar rings. When pressing the space bar to activate the emitter, sonar type rings appear. However, then the defined handle keys do not move the ROV. They have to refresh the URL before they can try again to see what might work.

My students are learning to code in 3D. They want to use the emitter as a sonar for an ROV; is this possible? They have tried to place the 3D emitter blocks under the add drone blocks. They have also tried to start the emitter when the space bar is pressed. Once the emitter starts, the ROV does not work when pressing the handle keys, and the emitter freezes. I love their enthusiasm; any help would be appreciated.
