vg4->misc->moving_one_step_to_dst()
Get positions when moving to a destination point.
SYNTAX
int
vg4->misc->moving_one_step_to_dst(const struct VG_RectCent *rectc_start,
const struct VG_Point *pt_dest,
int factor,
struct VG_RectCent **rectc_pos)
FUNCTION PARAMETERS
| rectc_start | Starting position |
| pt_dest | Destination point (centered) |
| factor | Positive factor in 1/10 pixel to multiply moving |
| rectc_pos | For returning allocated array with moving positions, must be freed with free() |
RETURN VALUE
Returns the number of elements in rectc_pos,
or 0 = destination reached
DESCRIPTION
Get positions when moving to a destination point.
The pt_dest is the destination point to seek, which will not be exceeded.
The factor controls the velocity.
A factor of 1 would move the object 1/10th pixel.
This function can be combined with vg4->misc->move_and_check_collisions().
