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

(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.
