This function will return the x position (in room coordinates) of the point that you input for the path that you index. If the point is outside of the range of the path (ie: a path has 8 points and you ask for the x position of point 10) then a value of 0 will be returned.

path_get_point_x(index, n);

Argument | Description |
---|---|

index | The index of the path to check. |

n | The point identity to check. |

Real

if path_position = 1

{

var i;

i =
floor(random(path_get_number(mypath)));

x = path_get_point_x(mypath, i);

y = path_get_point_y(mypath, i);

path_position = (1 /
path_get_number(mypath)) * i;

}

The above code will check to see if an instance is at the end of a path. If it is it will then choose a random point on the path and move the instance to that point.
