RayCast(LineTrace) In Uworld?

Development Programming & Scripting C++

Hey, I wanna know how to setup a Uworld class so I can start doing some linetrace(raycasting) through PhysX. I just wanna do it from the third person controller to what ever it hits.

Here is the link to the documentation for LineTraceSingle.
https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/Engine/UWorld/LineTraceSingle/1/index.html

Thanks in advance.

Op found something better
Well I am using ACharacter which is a subclass of Actor so I could technically use AActor::ActorLineTraceSingle.
Anyhelp would be awesome!

You can use:



GetWorld()->LineSingleTrace(*params*)

GetWorld() is a function which exists inside UObject so almost anything can use it.

ActorLineTraceSingle is different in that it actually performs per component trace hits instead.

So if you want to do a trace into the world then use the world method. If you want a more accurate Actor collision response then perform ActorLineTraceSingle on the Actor itself.
