Title: If height >=10 then SAY SOMETHING
Post by: XTimmy on 31 Dec 2008, 18:32:05

Hey.
I've been working on my 'first' mission for a few days now and it's beginning to grind ever so slightly.  I've reached a point where I need a function rather than a script.
Then I decided a Trigger would work just as well.
Basically I've got a helicopter rising in the distance. And when it hits a certain height (10) Crossroads says something to the affect of 'oh no'

I simply cannot get this to work.   

My current set up  (which dosen't return an error, it simply returns nothing is thus)
A trigger, axis a/b = 0/0,
Condition:
(getpos testheli select 2) >= 10
On Act
[sidefriendly, "HQ"] Sidechat "oh no"

I've tried variations of everything [side, "HQ"] Sidechat "oh no"   etc etc but it simply dosen't pop up. Any thoughts? 

(If someone could also make this into a .sqf so I've got an example function to learn the syntax for a looping script off that'd be great)

Try this:

Code: [Select]

HQ = [west, "HQ"]; HQ sideChat "Oh no!";


Here's the SQF:

Code: [Select]

while {alive testheli} do //loop as long as testheli is alive
{
if ((getPos testheli select 2) >= 10) then //check if testheli's height is greater or equal 10
{
HQ = [west, "HQ"];
HQ sideChat "Oh no!";
};

sleep 1; //wait 1 second before continuing - always sleep if the loop runs for extended amount of time or the game will freeze!
};

Sleep is exactly the command I've been looking for! 
Thanks for the help in both threads Deadfast!  :D

You're much welcome :)


I wish you good luck in learning SQF ;)

There is also waitUntil

which is equivalent to @ in SQS scripts if you're interested

IIRC waitUntil eats up more resources so I'd personally avoid it in this case ;)


BTW Timmy, I just realized you might want to have the message display only once.

In that case use exitWith instead of then with the if condition (it's similar to break in C-like languages):

Code: [Select]

while {alive testheli} do
{
if ((getPos testheli select 2) >= 10) exitWith //if the condition is true execute the code and then exit the while cycle scope
{
HQ = [west, "HQ"];
HQ sideChat "Oh no!";
};

sleep 1;
};

Nice to know but it only needs to execute once.

Yep, that's why you need exitWith ;)
