path_get_y(ind, pos);
参数 | 描述 |
---|---|
index | The index of the path to check. |
pos | How far through the path to check. Between 0 (start) and 1 (end). |
Returns: Real.
With this function you can get the y coordinate of a position on
any given path. 0 is the start of the path, 1 is the end of the
path, and anything in between equates to the normalised distance
along the length of the path. This value needn't be a defining
point of the path, it can be anywhere on it.
y = path_get_y( path0, 0.5 );
This will set the calling instance's y to the y coordinate of the point at exactly halfway through path0.
