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.

Example

This 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 ) )
