point_distance

point_distance

returns the pixel distance between two points based upon either two vector points or 2 sets of X-Y input points.

Syntax:

point_distance(p1, p2) //Vector
point_distance(x1, y1, x2, y2) //X-Y

Vector

Argument	Description
Vector2 p1	First position
Vector2 p2	Second position

X-Y

Argument	Description
double x1	First x position
double y1	First y position
double x2	Second x position
double y2	Second y position

Returns: double

Description:

This function will return the distance from the first point to the second point coordinates. It is useful for programming AI as well as enabling effects or spring traps.

Vector Example:

var GroundDistance = point_distance(Position, new Vector2(Position.x,room_height-64));

Above code will set var GroundDistance to the current distance of the player to the ground by vector.

X-Y Example 2:

var GroundDistance = point_distance(x,y,x,room_height-64);

Above code will set var GroundDistance to the current distance of the player to the ground by X-Y positions.
