String/Variable Identification

Hey y’all! I was struggling to find a way to identify strings vs. integers, and couldn’t find any solutions already up, so after racking my brain I came up with a subroutine. If anyone ever comes up with a similar issue, here’s my solution:

*create result false

(code and stuff here)

*label is_num
*params target
*temp length length(target)
*temp pointer 0
*temp count 0
*temp found_dot false
*temp found_negative false
*set result false
*if (target#1) = "-"
	*if length > 1
		*set pointer +1
		*set found_negative true
		*goto is_loop
	*set result false
	*return
*label is_loop
*set count 0
*set pointer +1
*if (target#pointer) = "."
	*if found_dot = false
		*if found_negative
			*if (pointer < length) and (pointer > 2)
				*set pointer+1
				*set found_dot true
				*goto is_result_loop
		*if found_negative = false
			*if (pointer < length) and (pointer > 1)
				*set pointer+1
				*set found_dot true
				*goto is_result_loop
	*set result false
	*return
*label num_chk
*if count <= 9
	*if (target#pointer) = count
		*goto is_result_loop
	*set count+1
	*goto num_chk
*set result false
*return 
*label is_result_loop
*if pointer < length
	*goto is_loop
*set result true
*return

It’s pretty intuitive, despite how the code looks. Basically, it just runs through the inputed variable and checks each character to see if it’s 0-9, and keeps track of “-” or “.” to account for negatives and decimals. To call it, just run:

*gosub_scene (scene where you put it) is_num (your variable)

And it should return true if it’s an integer, false if it’s anything else. Anyways, tell me if you come across any bugs or mistakes so I can fix it before it breaks my code anyone else’s code.

Thank you. Soon on late someone with simple economy in their games and variations of fixed values may need you script for filtering their results.

Some stats may use your solution in certain cases too.
