Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Modify AIPerception Sight Range at runtime [4.7.6]

I'm trying to manipulate my AI's vision radius at game time. This could be caused by a buff, upgrade or pickup. As it stands I see a get Sight Radius but not a set. Am I missing something or is it just not available until 4.8 (or maybe later)

Product Version: UE 4.7

You can do it in C++ quite easily

     FAISenseID Id = UAISense::GetSenseID(UAISense_Sight::StaticClass());
     if (!Id.IsValid())
         UE_LOG(LogTemp, Error, TEXT("Wrong Sense ID"));

     // GetPerception() = AIController->GetPerceptionComponent()
     auto Config = GetPerception()->GetSenseConfig(Id);
     if (Config == nullptr)
     auto ConfigSight = Cast<UAISenseConfig_Sight>(Config);
     // Save original lose range
     float LoseRange = ConfigSight->LoseSightRadius - ConfigSight->SightRadius;
     ConfigSight->SightRadius = NewRange;
     // Apply lose range to new radius of the sight
     ConfigSight->LoseSightRadius = ConfigSight->SightRadius + LoseRange;

Thanks for this code snippet, this made things quite easy to expose the functionality for blueprints!

It'd be nice to update the arc as well, for animations that have a creature looking around. Any chance on something like this being added as well?

It's not doable via blueprints at this point, but I'll file a feature request and try to squeeze it in for 4.9

Hope to see this included too. ;) Trying to have relaxed guards moving around their fireplace camp and not see player from far. While in firefights the range need to be doubled or more.

Edit: Actually could just add own distance check. But official solution could be nice too.

Hi mieszko

Was this option ever add to the BP ver ?

Any update on this one?

I too would like word on this if it's possible to do in blueprint yet. My player gets larger after a certain point and I want the AI to act accordingly since the player's 2d orthogonal camera width is x2.

PS: I don't know C++ and have been using blueprint for my simplistic 2D project. I hope that with time becoming proficient in blueprint will help me understand some of the fundamentals of coding in C++. (Before I started I didn't even know what a boolean was).

3 years..and 12 versions later. Got this squeezed in yet?
