Hi,
I've been trying to use a switch statement within the Loop() function, like



when running it, it will start with "case 0" fine. But weird things happen, for example if I called agk::createsprite in a case that runs only once, it will still run more than one time. What is going on? Am I missing something?

If you change your switch to a couple of if's will it still be weird?

try print out values at screen Print(Str(level))
and print something at beginning and before end function

@Fluorescent: yes it would become very confusing and awful. I have far more than three cases. But you are completely right, the problem does not appear if I use if-statements.

@Markus: I guess I can do something along those lines, and then come back with a more specific example/behavior; will do

Thank you both!

Sounds a bit weird (subroutines are a bit of a nono)

Instead of a subroutine you could try a function
and use the exitfunction

GOODLUCK

@fubarpk: thanks for the advice, I am not very familiar with programming best practices. So it's good to know that putting a switch within the loop statement is not the best way to go. The switch statement will have to go within the function, right?
I will try doing so and check if the problem vanishes.

Its more a problem with subroutines, I was brought up believe goto's are a nonono and gosub routines are just as bad
so its best to use a function when you can even if the function is void and has nothing passed to it

Oh I'm sorry your writing for tier2 I had a glimpse and thought it was tier1 subroutine oh dear I mustve needed sleep

in tier1 it looks like this but theory still same


in tier2 I noticed no default


The problem might not be the code here it may be how it is returning from the called routines by not exiting properly or always the same
for example exiting a non void function with a void parameter but compiler interprets it as 0 or something hard to tell without out seeing more code
when I look aqk your code again it really looks ok I just was lacking sleep and thought you was in tier1 using subroutines but add a default to the case that also may help

@fubarpk: thanks! Sorry for the late reply . Been busy with my day job . I'll try this option that you are proposing as soon as I get a chance. And I will let you know if it solves the issue.

OK, I'm just writing this post because I feel like it's my duty to wrap it up. I was making a mistake and thanks to Markus's suggestion I found it out.
Lesson: use the print command to find out where your program get's stuck. It's a very good way to debug.
Thanks Fluorescent, Markus, and Fubarpk!
