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.
path_get_point_y(index, n);
| Argument | Type | Description |
|---|---|---|
| index | Path Asset | The index of the path to check. |
| n | Real | The point number to check. |
if (path_position == 1)
{
var _num = path_get_number(pth_Patrol);
var _pos = floor(random(_num));
x = path_get_point_x(pth_Patrol, _pos);
y = path_get_point_y(pth_Patrol, _pos);
path_position = (1 / _num) * _pos;
}
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.
