Posting for a friend. He is using Bernie's simple platform movement v0.1 and he has run into two problems.
1) the character/player doesn't animate when walking
2) he can only jump onto one platform but when he tries to jump again on the new platform nothing happens.
His also not sure whether this module is really old or not because it's the only one he could find at the time.
[EDIT] I found an old thread(not easy to find threads for this module) and it explained how to fix the animation part. So only the jump problem to solve.
