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.
