stand still and walking, a walking/stand still sprite change problem Options

[mavsith]

Hi people,

I think I have another difficult problem. I'm wondering if anyone knows how to fix this.
The problem is:
In a charset rpg maker 2003 only handles 3 posses of the character but sometimes the "stand still" pose combined when
walking with the charcater (hero) can look very stupid like the character is limping or whatever.

So the question is:
Is there a way that when you press one of directional keys you can change your character sprite with a better walking sprite and when the
key is "unpressed" the character sprite changes back to a standing stiil sprite. It's obvious you'll need 2 character sprites.

It's a little bit difficult to explain but if someone follows me do you know a way to fix this?
Looking forward for any comments.

Thanks in advance!
