Hey.
This here is a tutorial I made for people who just might want to have a mini 
game or some part in a dungeon where you must push blocks to proceed in the 
dungeon.
So here it is just for you.

1 - First of all, you must make an event. Event start is on Push Key. In 
Select Graphic, pick out a barrell or a crate or something that looks 
humanly pushable. Or monsterly pushable, depending on your game.
2 - In that event make FOUR fork conditions. I always check the ELSE thing. 
You will do so as well.
3 - In each fork condition, make it so that if your hero is, for example, 
facing up and when you press your key the hero and the barrel will both move 
up. It give the appearance of pushing the barrel... I suppose.
4 - So forth with moving right.
5 - ...and down
6 - and left.

Your whole event's code should look similar to this, if not exactly the 
same.

<>FORK Optn:Hero - Up Face Direct
<>Move Event...:  Hero, Up
<>Move Event...:  This Event, Up
<>
:ELSE Case
<>
:END CASE
<>FORK Optn: Hero - Rt Face Direct
<>Move Event...:  Hero, Right
<>Move Event...:  this Event, Right
<>
:ELSE Case
<>
:END Case
<>FORK Optn:Hero - Dw Face Direct
<>Move Event...:  Hero, Down
<>Move Event...:  this Event, Down
<>
:ELSE Case
<>
:END
<>Fork Optn:Hero - Lf Face Direct
<>Move Event...:  Hero, Left
<>Move Event...:  This event, Left
<>
:ELSE Case
<>
:END Case
<>

Now, in the case that you do not want your barrels to leave a specific area 
you must either put some dumb fencing around it or walls or whatever... 
OR... you do it this way.

1 - Tile the ground the barrels are going to be able to move around on with 
a different tile than the rest of the map. (Optional. It just shows how 
large the area is.)
2 - Make an event. No graphic and make it below hero and check off that 
allow event overlap thing just below.
3 - Surround the outside rim of the area that you do not want your barrels 
to leave.

Now when you push the barrels, they can't leave your differently tiled area 
you made.
There's no code for that one. Lucky me.

Well, one more thing. Make sure that your characters on map speed is the 
same as the barrel's moving speed. Otherwise the barrel will move to the 
next spot faster than the hero or the hero will try to move to the spot the 
barrel is at before it has moved.
