Directional Trace

[Derp]

Sorry about the stupid question, but how would I perform a directional trace(To the left, or right)?

This works all fine and dandy but the trace is unaffected by the pawn's rotation, so If I were facing forward the trace would trace to the right, but if I turned to face the right, the trace would still being going to the right, going "forward" to my rotation.

TraceStart = Pawn.Location - vect(0,0,10);
TraceEnd = TraceStart + vect(0,-30,0);

So you want the trace to always go in the direction you are facing?

TraceStart = Pawn.Location;
TraceEnd = TraceStart + vector(Pawn.Rotation) * dist; //dist is how far you want your trace to go, vector() returns a normalized vector with a length of 1

That isn't the problem, I want to trace to go directional to the player (Left or Right), begin affected by the direction the player's facing.

Okay, well that means the vector for the direction you are searching has a dot product of 0 with vector(Pawn.Rotation). I assume you don't want to trace up or down so that vectors z component will be 0. Now to get a vector that is orthogonal all you have to do is swap x and y and multiply either x or y by -1.

Whether your vector goes to the left or the right depends on which component got multiplied by -1.

TraceStart = Pawn.Location;

dir = vector(Pawn.Rotation);
//swap x and y
temp = dir.x;
dir.x = -dir.y; //to the left
dir.y = temp;

dir.z = 0.0f;
dir = normal(dir); //renormalize as we have nulled the z component

TraceEnd = TraceStart + dir * dist; //dir is the new vector for the direction, either left or right; dist just like before

RightVector = Normal(vector(Pawn.Rotation) cross vect(0, 0, 1));

or

local vector X, Y, Z;
GetAxes(Pawn.Rotation, X, Y, Z);

Using Y as left/right.

Haha, why did I not think of this simple approach?

Vector math is confusing sometimes.
