In the realization of an isometric game as it can be to chess in which the pieces identified as bearer must only move diagonally, can only move in four directions (northeast, northwest, southeast, southwest), to make it to offer an effect isometric real, I recommended to block the movements of the player inside an invisible grid, or simply to insert the movements indicated above by setting the moving speed so that the character is not located in the middle between never a square and the other of scacchiera.ma that his "race" always ends in a square?
I hope to have been clear. As usual, I apologize for my bad grammar.
