(This is the distance away from the camera to check fora collision. Multiply this Get Forward Vector value by 5000 (Multiple Vector by Float) to get a point in space from 0,0,0 that is 5000 units away facing the direction of the camera. This will get the direction your camera is facing of your camera.

This will get the rotation of your camera and even works multiplayer games.Īfterwards connect the Get Control Rotation node to the Get Forward Vector node. Next using the Get Controller node, get the controller rotation from the Get Control Rotation node. Breaking down the Mathsįirstly you use the FirstPersonCamera variable connected to the GetWorldLocation node to begin the line trace from your character’s camera position. The nodes below setup the vector maths required to check for any collisions wherever the camera is located and facing. (These can be viewed and created in the collision tab of the project settings) How to Calculate the First Person Line TraceĪll line traces have the same basic setup. “Line Trace by Channel” checks for an intersection with a specific collision profile by name. (Visibility and Camera are the default options) “Line Trace by Channel” checks for an intersection with a specific line trace collision channel. (WorldStatic, WorldDynamic, Pawn, Ragdoll, PhysicsActor, etc) “Line Trace for Objects” checks an intersection with a specific collision object type. the actor that was hit and distance from hit.

The hit data is then broken down access more information such as location of hit, normal of hit. A line trace is a way to check if an object is intersecting a line.
