Are you sure that the trace hits something? If the Out Hit Location always returns (0,0,0) I doubt it does. Please make sure it does. Normally you want a branch after the LineTrace where the Out Hit Blocking Hit is plugged into the condition to make sure the logic is only executed if the trace hits something. Btw are you sure you want to plug all pawns into the ActorsToIgnore input? These are most likely the ones you want to check with your trace.
