''fixed VectorLength3D(fixed x, fixed y, fixed z)''

===== Description =====
Returns the length of the given 3D vector.

===== Example =====
Show 3D distance between actors:
<code>
int x = GetActorX(tid2) - GetActorX(tid1);
int y = GetActorY(tid2) - GetActorY(tid1);
int z = GetActorZ(tid2) - GetActorZ(tid1);
int distance = length3d(x, y, z),
print(s:"The two actors are ", f:distance, s:" mapunits apart in 3D space");
</code>

<note tip>Use [[ActorDistance]] instead of the example code above.</note>
