The following two scripts both create the API command <code>!fly</code>. The first script is functionally limited to the values 1-9, while the second script is not. However, the second script makes use of an API feature which may or may not be intentional, meaning that it might be broken by an update to Roll20 in the future.

API ScriptAuthor: Brian, The Aaron
Version: 3.4
Last Modified: 2016-08-15
Code: Flight
Dependencies: splitArgs
Conflicts: None

Flight creates the API command !fly, which sets statusmarkers on the selected tokens to represent how high they are flying.

[edit] Syntax

!fly [height]
Formally:

S 

→ !fly height


height 

→ ε

height 

→ integer
Parameter Values
height Optional. Set the height of the selected token(s). If this parameter is 0, negative, or omitted, the flight value will be removed from the token(s).

[edit] Notes

Numbers with multiple digits will create multiple wing statusmarkers, one for each digit. Zero digits (for example, the tens digit of "205") will show up as a wing statusmarker with no number.
