Well, pseudo-code is not going to work by nature. So that is no surprise I guess. What I tried to achieve was to steer the questionnaire in the right direction by keeping it simple without filling in all the blanks. After all, an unexperienced scripter would struggle immensely with matters like inverse kinematics.
I do agree about my answer being terrible. That is because this stuff has already been done before. The topic contains quite a few code samples along with some good ideas on how to implement climbing.
