Creating an Undo Command for Sokoban

[pixelink]

TO... Simflare, UlitmateWarrior, Caesar

I am making a game for my disabled wide called Sokoban... ever heard of it?

See it here:

So, I got a hold of the undo example that was in this thread.
I got it implemented fairly easily.

When my bulldozer moves, I have it pointing in the direction it's going using the "Walking" animation (just 1 frame)

The UNDO works awesome... however, in my game when I undo the bulldozer stays in the last "walking" position I was at.
And I know that the Undo array isn't saving the walking direction.

Q: How can I save the walking direction in the array??

I would appreciate any input you all may have.

Save it in a spare column. For instance the undo example uses 0,1,2 on the X of the array. So you could use 3 to store the direction.

Okay... I will give it a shot

2 Questions...

1) Since the array is numerical... what value do I use for direction?

2) I would like to limit the undo's to just 1 but keep the code in tack.
I am thinking of using a global value that I set for the number of limited undo's.
What would be the best way to do this?

This is my attempt

If UndoLimit <=1 then stop the loop.... doesn't work

The inbuilt directions are 0-31. So you can store just the current direction.

Okay... I am almost there.
However, I can't seem to get the RecoverObj even entered.
I don't seem to have the option to get the value from the array.

When I select the Direction on the "move-able" object, all I get is the window where you manually select which direction (the one that looks like a clock)
I have no option to add further code.

I am sure I am missing something.

You can press 1+1 to use an expression.

You can press 1+1 to use an expression.

Check this out...
It doesn't work though.

Should I be specifiying whether it's Stopping Dir or Walking Dir.
I have my bulldozer face the direction on both Stopping and walking

Can anyone shed light on why the undo function of these events is not setting the direction of the player?
