Title: "if statement in a while loop" troubles
Post by: IceShade on 06 Jun 2009, 03:49:26

Hi there, it's been a while since I've been here. I think my last post was somewhere in.. 2004. Good to see my account is still active ;)

In any case, I'm having some trouble with this code.

Code: [Select]

while {true} do
{
"start" setmarkerpos (getpos me);

if (testvar == true) then
{
"testmark" setmarkerpos (getpos me);
};

sleep 5;
};

An infinite while loop, sets the "start" marker to "me" location. It reaches the if statement, which is supposed to set a new marker at my location if testvar equals true.

Wait 5 seconds, do it all over again.

Without the if statement, this works fine. The "start" marker updates every 5 seconds on my position. With the if statement, however, it will execute the "start" marker setmarkerpos once, and then die.

I am clueless as what can go wrong here. Just to be sure, I defined "testvar" as false first (at the very start of the init.sqf), then set testvar = true, then called the script.

Surely I'm doing something wrong and this isn't a sqf limitation? I'd hate to make a second script just to get a second marker on my position (that requires a condition).

Try this... however its not breaking out of the code anywhere.

Code: [Select]

testvar = true;


while {testvar} do
{
"start" setmarkerpos (getpos me);

if (testvar == true) then
{
"testmark" setmarkerpos (getpos me);
};

sleep 5;
};

When doing boolean checks you don't need to use ==

Code: [Select]

while {true} do
{
"start" setmarkerpos (getpos me);

if (testvar) then
{
"testmark" setmarkerpos (getpos me);
};

sleep 5;
};

There we go! I didn't imagine that it would actually matter, but apparently sqf is very picky about its syntax.

Thanks guys, it's always better to have a few extra minds to look over some code that doesn't seem to work (but the answer is always so obvious).

It has always been like that to my knowledge, no matter if it is sqs or sqf.

I'll go ahead and lock this now -> resolved.
