''fixed length2d(fixed x, fixed y)''

===== Description =====
Returns the length of the given 2D vector.

This is a Zandronum replacement for [[zdoom>VectorLength]].

===== Example =====
Egyptian triangle:
<code>
length2d(3.0, 4.0) -> 5.0
</code>

Show XY distance between actors:
<code>
int x = GetActorX(tid2) - GetActorX(tid1);
int y = GetActorY(tid2) - GetActorY(tid1);
int distance = length2d(x, y),
print(s:"The two actors are ", f:distance, s:" mapunits apart on the automap");
</code>

<note tip>Use [[ActorDistance2D]] instead of the example code above.</note>
