path_clear_points(index);
| 参数 | 描述 |
|---|---|
| index | The index of the path to clear. |
返回： N/A（无返回值）
With this function you can remove all point definitions from a
path, effectively making an "empty" path. This does not
delete the path, for that you should use path_delete.
if path_get_number(mypath) > 0
{
path_clear_points(mypath);
}
The above code checks to see if there are any points on the path indexed in the variable "mypath" and if there are, it clears the path.
