For some odd reason, I cannot get the mantle, jump up, or jump down animations to play for certain heights/distances. I also could not replicate your tutorial in radiant. For whatever reason it just didn't want to work.

Note work for me 

If anyone is having problems doing it this way, jbird put a video on youtube recently in which he has prefabs made for every anim in the script so far. Look up his video and the download link is in the description. Just save them in your prefabs and drag and drop. He made it super easy.

Thanks man! sorted out my issue via searching through the scripts but these prefabs are a huge time saver!
