Hey guys, one day I was working on a game and whenever I tried to look for this function I couldn't find it, could tell me why this happens or a way to find the function? Thanks I appreciate it. (Note: It only happens with the mac version of the program).

random_range() is new to GM8.1, but GM4Mac doesn't have it yet. You can create one yourself, though:

return argument0+random(argument1-argument0);

If you name this script random_range, you get the exact same functionality.

Thank you so much!

Now I have another problem, after I wrote this: random_range = return argument0+random(argument1-argument0);    and then started the game an error came which said this:

COMPILATION ERROR in Script: random_range
Error in code at line 1:
   random_range = return argument0+random(argument1-argument0);

at position 14: Variable name expected.

You are meant to add a new script, named 'random_range', and paste GameGeisha's code there.
Interesting behaviours.

No, that's not how it's done. The script should contain just the return statement. The assignment statement does not belong in there.

return argument0+random(argument1-argument0);

Then you can call it as though it was a built-in function:

random_percentage = random_range(0, 100);

Defining scripts and calling them in this fashion is a basic technique that should stick.

Ok thanks but one last question I did everything you told me but when I put this code
age = random_range (0, 20);

show_message(age);      

It shows nothing in the dialog box when I start the game, it shows nothing is blank.....

First of all, you should turn the option that displays errors back on. Don't chicken out of problems caused by your coding. Let GM inform you to the best of its ability, and you should take an active role in fixing them.

random_range() returns a real value, while show_message() expects a string. Passing a real value into a function that expects a string argument is not valid. To make this valid, you need to use string() to turn the result into a string:

age = random_range(0, 20);
show_message(string(age));

Thanks and sorry for the nuisance
