示例1: start_next_elementary_move
/**
* \brief Starts the next 8-pixel trajectory of the path movement.
*
* This function is called when an 8-pixel trajectory of the movement is finished,
* or when the movement is restarted.
* Before starting the 8-pixel move, if the property must_be_aligned is true,
* the entity's top-left corner tries to get aligned with the 8*8 squares of the grid.
