Returns the y coordinate of a given path's given defining point.


path_get_point_y(index, n);

参数 描述
index The index of the path to check.
.n The point identity to check.

Returns: Real.


This function will return the y 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 y position of point 10) then a value of 0 will be returned.


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.
