I know this is sort of an old post, but I'll answer anyway if somebody else finding this question from Google comes here.
I suggest that you make a Path2D going along with the game-board. Then you slide the Path-node's offset so the moving character is on the point and write down what is the offset of every point in the game-board.
Then make variable, example "var board_point = 0"
then in physics(delta) function: if boardpoint == 1: setoffset(input here the offset you wrote down from point 1), if boardpoint == 2: set_offset(*input here the offset you wrote down from point 2*) and so on...
Then you write the function for dice rolling. In the roll-function: boardpoint += diceroll
For example: Player is in point 2 on game-board, you roll 6 -> board-point=8 -> player goes to offset which is indication on point 8.
Like this player instantly teleports to the point, so you can make extra-variable for counting down the dice-number and use timer to slow down the movement. And going between points you can use Tween-node to make the movement animated.
I made an example:
var board_position = 1 #dice roll changes this
var Path_Offset = 0 #this is the offset which board_position puts it in _physics_process
if board_position == 1:
Path_Offset = 0 #this is the first point and it is on 0 in the path
if board_position == 2:
Path_Offset = 438 # this is second point's offset
if board_position == 3:
Path_Offset = 860
if board_position == 4:
Path_Offset = 1252
if board_position == 5:
Path_Offset = 1590
if board_position == 6:
Path_Offset = 1845
if board_position == 7:
Path_Offset = 2172
#This is just showing with pressing Enter/Return that the example works
board_position += 1
Here is video of it working:
