Returns the x coordinate of a given path's given position.


path_get_x(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 x 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 that far through the path. This needn't be a defining point of the path, it can be anywhere on it.


x = path_get_x( path0, 0.5 );

This will set the calling instance's x to the x coordinate of the point at exactly halfway through path0.
