Will the outcomes be corresponding in this random behaviour tree?

closed account (367kGNh0)
Hello,

Here are the key parts of two behaviour tree with random outcomes. Not seen in the code i should specify, the trees are in the same method. All other code for random in c++ (e.g #define <ctime> ) are specified elsewhere.

I just ask, will the two behaviour tree outcomes always be corresponding, or would they be completely random and un-related?

If you're asking if PencilTextl is always the same in both blocks of code, then the answer is yes.

TBH, you can do away with a lot of code.

Thanks @salem c

That closes this, but do you know how I can ensure both are random without making two

int name = rand()
?

I cannot tell if your code is the solution, or advice to use less code
