Here is my sixth build of Throbe. It demonstrates Power-Fields, Barrier-Fields, Power-Cores, power connections, and Heavy-Cubes.
Power-Fields (semi-transparent blue in the video)
A power-field sends power to any power-receiving object that enters it.
Barrier-Fields (semi-transparent white with grid in the video)
A barrier-field is basically a wall that can be turned on and off, when given power.
Power-Core (red ball in video)
A power-core can accept power from a power-field. Usually a power-core will have a connection to a set of elements that can receive power. In the video, the barrier is a connected element of the core. So when the core gets power from the field, the barrier gets power from the core and switches off.
A heavy cube is exactly what you think it is. This cube may be used to push buttons later on - although this is subject to change.
Feedback is appreciated :]
