[Resolved] testing if a variable is a string or numeric value

[Draycos Goldaryn]

Ok, now how do I do this?

if [i]variable1[/i] is a number and [i]variable2[/i] is a string
  do this
else
  do that
end

This might fix another problem I'm having....

Use this:

if variable1.is_a?(String)
  do this
elsif variable1.is_a?(Numeric)
  do that
end

 

[Trickster]

use the <object>.is_a?(<class>) method

is_a? checks if <object> is an instance off <class> or a class that inherits from it

for example to check if its a number use this

variable.is_a?(Numeric)

and to check if its a string use this

variable.is_a?(String)

Numeric is the parent class of all numbers Integer or Float and String is the class of strings (characters, words, etc.)

ok, that is good info, unfortunately, it did not help. maybe if I was more specific:

          if $game_map.check_event(x, y).is_a(Numeric)
            return
          else
            $game_player.find_path(x,y)
          end

gives the error:

undefined method `is_a' for #<Array:0x145f170>

when there is no event there, and

undefined method `is_a' for 3:Fixnum

when event with the id of 3 is there.

Note: variables 'x' and 'y' are defined in the two lines before the posted code.

It's is_a?, not is_a.
