What is the formula for calculating the the linear distance between two vector points?
Thanks

vector vec1;
vector vec2;
float linear_distance;
linear_distance = llSqrt(((vec1.x - vec2.x)*(vec1.x - vec2.x)) +
((vec1.y - vec2.y)*(vec1.y - vec2.y)) +
((vec1.z - vec2.z)*(vec1.z - vec2.z)));

If you, like me, are too lazy to type that in... float llVecDist(vector v1, vector v2) |

Or if you have a grudge against llVecDist you can use...
llVecMag(v1 - v2)
Not sure why you would...

PHP Code?
Have I missed something fundamental, like LSL is implemented in PHP and runs PHP code?

Forum bug...

No, Tommy -
Its just a forum bug/issue when surrounding code with the markup to make it appear in those little code-boxes. LSL is completely distinct from PHP.
Take care,

That's a relief. Damned near had me dumbfounded there. Not that I have anything against PHP, just not for implementing another scripting language.
