===============================
guys i was trying to change the default world of roaming ralph to my own created world… what seems to be the problem?
the function model.find("…") searches the level model for a object or empty named “start_point”, because it cannot find it, it’s crashing.
remove that line and position ralph manually, or modify your terrain. most probably you will run into collisionproblems as well. search for “polyset keep descend” and check the manual if that happens.
““most probably you will run into collisionproblems as well. search for “polyset keep descend” and check the manual if that happens.””
Yes I have tried removing or commenting the start_point script, and somehow I have successfully changed the map. Now i’m having problem with the collision. Can you explain to me what the “Polyset keep Descend” means? thanks
