CA_RayCastLineID crash

[NexiusTailer]

So, after a long test I get the crash: if you use CA_RayCastLineID at water (20000), then instead of return that number you will see this:

[22:22:30] [debug] Server crashed while executing creator.amx

P.s. CA_RayCastLineID also return 0 if collision not found, but objects which added by CA_CreateObject also can have id (index) 0..

Totally correct. I'll fix that when I get home in a few weeks or so unless someone wants to do it for me, it's pretty simple. (@Pottus?)

But about the crash, I'm not sure. Perhaps you could do some more tests. Like cast rays on _SC objects?

[NexiusTailer]

Any created objects didn't exist.
Unfortunately I not fully understand the problem.
With -d3 crashdetect only confirmed that the problem in this function

However, this code must crash your server:

public OnPlayerUpdate(playerid)
{
new Float:tmp;
CA_RayCastLineID(1983.875366, 555.897338, 11.122355, 2028.804321, 567.251770, -7.651627, tmp, tmp, tmp); //even without any checks, just use function
return 1;
}

I do not know, but the crash occurs precisely around these coordinates

Try this.
https://github.com/Pottus/ColAndreas/blob/master/src/DynamicWorld.cpp#L115

index = -1;
ColAndreasObjectTracker* tracker = NULL;
tracker = (ColAndreasObjectTracker*)RayCallback.m_collisionObject->getUserPointer();
if(tracker) //always be safe while manipulating pointer
    index = tracker->realIndex;
