Player bigger then tile-size

I’ve searched high and low, but sadly not found the answer to my problem…

I’m making a game with help of Tonypa’s tutorial on tile-based games,
the hero in my game is 30 in width and 70 in height,
my tiles are 40 x 40… how can I make it work…?

game.clip.attachMovie(“char”, “char”, 10000);
char.clip = game.clip.char;
char.x = (char.xtile * game.tileW)+game.tileW/2;
char.y = (char.ytile * game.tileH)+game.tileH/2;
char.width = char.clip._width/2;
char.height = char.clip._height/2;
char.clip._x = char.x;
char.clip._y = char.y;

And further down he wrote:

Note that you can create your own boundaries, you dont have to use width and height of movie clip. Some heros might have long puffy hair which can collide with walls, then declare your own width and height variables

What do I need to change?
Tried changing:
char.width = char.clip._width/2;
char.height = char.clip._height/2;
to:
char.width = 30;
char.height = 70;
but it didn’t help much, as when I jumped, he landed in mid-air… :frowning:
