Ok. I have scratched my head long enough. I am having an ID10T error. I am trying to use Vector3.MoveTowards to move my character on a grid. My script works just as I expect it to work after the first move. The player moves smoothly on the X or Y axis from one grid cell to the next and always stops at exactly in the grid. However, on the first press of the movement keys the MoveToward is telling the player transform to move to the next cell. I have posted my feeble attempt at debugging this issue. As you can see I inserted a log before the MoveTowards and after. In frame 993, moves one full cell in the MoveTowards. I’m sure I am missing something simple, but I can’t figure it out. Any help would be appreciated.
Thanks
