Does any one know how to make a charactor move in tiles instead of freely?

Oh that's tough. The easiest might be to have the player actor move to the center of the tile whenever it collides with a tile. Just create an event when a collision happens that moves the actor to the center of the collision tile.

If your tiles are 32x32 then use keydown "right arrow" -> script editor -> x=x+32;
