path_insert_point(index, n, x, y, speed);
| 参数 | 描述 |
|---|---|
| index | The index of the path to insert the point into. |
| .n | The defining point to insert the new point BEFORE. |
| x | The x coordinate (relative to the path) of the new point. |
| y | The y coordinate (relative to the path) of the new point. |
| speed | The speed factor of the point. |
返回： N/A（无返回值）
With this function you can insert a new point into a path (the
path can have been created in the path editor or through code using
path_add). The point will be
added into the path before the point "n" that is specified in the
function.
path_insert_point(mypath, 0, 50, 50, 100);
This will insert a point at the very beginning of the path indexed in the variable "mypath", at (50,50), with a speed factor of 100%.
