I am attempting to create a custom nav area that cannot be traversed, similar to the NavArea_Null provided by the engine. The c++ code for the engine’s Nav Area has this:
DefaultCost = BIG_NUMBER;
It seems as if BIG_NUMBER is what is used to stop AI from entering that area, but what exactly is BIG_NUMBER? How would I create my own null Nav Area without creating a Nav Area in C++ and doing the same thing?
