I have no idea what's causing this...

Basically, when the unit tries to fire (which is as soon as it is ordered to, pretty much), Spring crashes.

How about some Cash on Fire ???

Posted: **10 Oct 2006, 23:39**

in fireprimary you had the script go through all the ifs as one if made the condition right for the other. you had the first if set fpuse to what would cause the second if to go off and etc. This cause queryprimary piecenum to change through all the points in 0 time everytime the unit fires. This might cause spring to crash depends on how spring handles such thing. You know, "++gun_1" at the end works much better.

I'd use else statements though. Means less cycles.

I can only guess what makes it crash: it's the SPARK effect you are calling from within the script.

Also:
if(HealthLevel < 75 || HealthLevel >= 50)
{
emit-sfx 1024+0 from smoke1; //sparks
sleep 200; //If I didn't add this, Spring would spawn smoke every milisecond. Which is a bad idea - much lag
}

Triggers if either HealthLevel is below 75 OR greater or equal to 50. Which means it always triggers and emits your sparks. The || need to become && or AND (correct me if I'm wrong).
Now if the spark effect is broken (which is what I assume) then you have your reason why spring instantly crashes (because it's emitted right after spawning the unit, more or less). It's probably only a single argument in the SPARK explosion which breaks it.

Ugh, ignore the above. Sorry I'm tired.
It's the emit-sfx 1024+2 which makes spring crash. It wants to emit the explosion from explosiongenerator2 which does not exist in your FBI.

Also, the weapon had a typo- 1 missing } to close it.

I should also note, for the record, that you can use the more-readable "OR" instead of the dual-pipe "||"

All above problems fixed! Thanks for the help!

Now, this little quirk has been a thorn in my side for quite a while now (it also exists in Epic Legions):

Basically, it doesn't show the missile model.

I have a vague recollection that Spring only shows the base object on weapons. Is this true?

Is it just me or does that explosion look cool?

Posted: **11 Oct 2006, 18:26**

GMN seems to know what he's doing. :)
Oh is it an s3o model? Don't know if you need a hitsphere on it.

edit: Just figured, it's not an explosion, it's the smoke trail and flare.

Posted: **12 Oct 2006, 04:47**

S3Os should have hitspheres defined. Set it to a minimum radius size of 8 for consistant hit results in Spring, even if that means the radius is larger than the shot by a bit. It'll also make sure the object shows up. And yeah, the root object is what's shown.
