Note: This function is equivalent to the Vector2 class getLength method when used with a vector that holds the direction and distance between two points. In other words, it produces exactly the same result as substracting the points' coordinates and getting the length of the result vector. |
This function returns the distance between two 2 dimensional points using the pythagorean theorem.
Syntax
float getDistanceBetweenPoints2D ( float x1, float y1, float x2, float y2 )
Required Arguments
- x1: The X position of the first point
- y1: The Y position of the first point
- x2: The X position of the second point
- y2: The Y position of the second point
Returns
Returns a float containing the 2D distance between the two points. Returns false if invalid parameters are passed.

Server and clientThis example gets the distance between two vehicles, stored in variables vehicle1 and vehicle2.
vehicle1x, vehicle1y, vehicle1z = getElementPosition ( vehicle1 ) vehicle2x, vehicle2y, vehicle2z = getElementPosition ( vehicle2 ) outputChatBox ( "The map distance between vehicle1 and vehicle2 is ", getDistanceBetweenPoints2D ( vehicle1x, vehicle1y, vehicle2x, vehicle2y ) )

Server and clientThis example shows the maths behind getting the distance between points and is also more efficient if your script is calling this function extremely often.
math.sqrt((p2x - p1x) * (p2x - p1x) + (p2y - p1y) * (p2y - p1y))
