Summary
SUMMARY: Infrastructure "Change within_visual_range function to reflect usage"
Purpose of change
Original function returns an integer and is only ever used as a component in boolean expression. Because of this sole pattern of use it makes sense to make it just a boolean result not reliant on a magic number signifying invalidity.
Describe the solution
Change return type from
int
tobool
, modify conditionals reliant on the function.
