These can be used to enter hard-coded data directly into our graphs (analgous in programming to using 'literals').Moreover, by using the
Set variableblock, we can declare and assign to variables in order to save data within our graph's data context. Data stored this way can be retrieved with
Get variableblocks. This category also contains the
Is Variable Existblock, which determines which path to execute based upon whether a variable by a given name has already been declared with a
Set variableblock. Finally, this category also contains the
Variable Portalblock, which allows us to pipe data from one area of our graph to another while keeping things visually tidy.
