Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI.  Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately.  The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.

This block maps a value to a unique variable. You can use the variable in the parameter field of another block simply by using the Variable Block's ID.

The variable block is a convenient way to have one value that is used in a bunch of different places (i.e. parameters of other blocks) while being able to easily change it.

Also see the Parameter Block.

Parameters[edit]

(R): Run-time adjustable

ID
ID of variable name. Use this to reference the variable in other block's fields.
Value (R)
Value, which can be changed in realtime.
