thx, but i cant get the functions to return a variable, then use it. i made a function

but then when i tell it to print dist# it prints 0. when i put the code in my main loop withought a function and replace obj and obj2 with 100 and 200 the same numbers i gave the function when i called it by using distance(100,200) it works and reports correct values when i tell it to print dist#
the code i put in my main loop replacing obj with 100 and obj2 with 200 is

or



You were probably either not using a float to store the returned value, or trying to access dist# from outside the loop, when you should have been using the returned value from the function.

When a function returns a value, you can think of that function as like a variable itself.
dist# is a local variable to the function. Meaning that only the function itself knows that variable exists. A global variable is one that can be seen by all functions.
