ele_user Any machine that uses power
|
|
ele_storage Any machine that stores power

Static capacitor for nodes.
|

Decides how much power can be inserted into this machine's internal capacitor.
|
|
** Can be overridden by metadata: `inrush`
|
|
|
|
ele_output = 64
|
|
Decides how much power a `ele_provider` node can output.
|
|
** SHOULD be overridden by metadata: `output`
|
|
|
|
ele_sides = nil
|

ele_active_node = nil
|

Set to true or a string to also register an active variant of this node.

If the parameter is a boolean, "_active" will be appended to the `node_name`

ele_active_nodedef = nil
|
|
If set, the `ele_active_node` will have this table in its nodedef.
