[QUESTION] How to get point to point distance?

[TheMallard]

Hello!
I've created a small function, and I don't know, it works properly or not.
Is this the right code?

Code Select Expand

function getPointDistanceToPoint(x1, y1, z1, x2, y2, z2)
{
return Vector(x1-x2, y1-y2, z1-z2).Length();
}

Nope. You can't get the length of a class/instance.

And the length function is: len() and not Length()
Still then, I can't know what you're talking about.

 :edit: This code might help you:-

Code Select Expand

function IsPlayerInRangeOfPoint(v1, v2, range) // by Rusty_Bullet22
{
  v1.x -= v2.x, v1.y -= v2.y, v1.z -= v2.z;
  return ((v1.x * v1.x) + (v1.y * v1.y) + (v1.z * v1.z)) < (range * range);
  /*
Returns true if the player is within a range of 1500 from (0,0,0)
false if not
IsPlayerInRangeOfPoint( player.Pos, Vector( 0, 0, 0 ), 1500 );
  */
} I haven't made it, @Cutton did.

My function works properly.

Class Vector has a method, called "Length()"

He's not talking about the container element count /length such as array/table/string. He's talking about the the distance between two points in 3 dimensional space. And the method he's calling is on the Vector instance.

You are wrong. Vector has the "Length" method.

Why did you actually create the code,
It could have been Found over here, than why make functions, I'm just curious to know why?

Maybe he don't know there is such function. I don't know too.

Okay, well that's not really a serious problem/issue thou.

You can use Vector.Distance( Vector) to get the distance in 3d.

function getPointDistanceToPoint(x1, y1, z1, x2, y2, z2)
{
 return Vector(x, y, z).Distance( Vector( x2, y2, z2 ) );
}
