I've made a simple clone of the classic game Sokoban. And the player moves in a grid, just like in the original.

I'm moving the player using the really simple formula
x# = gridX# + tileWidth# * gridx
Where gridX# is the place where the grid starts on the screen, tileWidth# is obviously the width of a grid tile and gridx is the number of the column in the grid. And I have the same for Y.

The player is snapped to the grid, it works great. But in one frame the player has moved to the adjacent tile and I think that I want to animate the player walking between the tiles. At the same time I don't want the player to be able to change direction when he is between to tiles so the character is no longer snapped to the grid.

I'm note sure how to solve this, does anybody have a suggestion on how this is accomplished?

Hi, you can move the player sprite via a tween in small steps (pixels) from one tile to the neighboring tile.

You could try using a positioning tween to move the sprite from one point to another. Look up:
SetTweenSpriteX
SetTweenSpriteY
PlayTweenSprite
and
UpdateAllTweens

The tween functions seems to be a great way to solve this. But they don't use the offset of the sprites do they? I'm assuming that I am placing my sprites using the SetSpriteXByOffset and so on.

You could try manually adjusting the offset e.g.:
SetTweenSpriteX( tweenID, beginX-offset, endX-offset, interpolation )
Default offset would be half the width of your sprite.
