Hooookay. After many frustrating hours of work, I just cannot get the "Traceline" triggers to work as presented by Shadowstorm (http://forums.sc2mapster.com/resources/trigger-libraries/7277-third-person-shooter-tps-engine-download-if-you-need/). What currently works is this: When I left click the animation is shown for the attacking unit and the sound is played. No damage is dealt to units. Also, I have already set the unit heights for all of the units as Shadowstorm did.

Here are my triggers:

Traceline
    Options: Action
    Return Type: (None)
    Parameters
        Player = 0 <Integer>
    Grammar Text: Traceline(Player)
    Hint Text: (None)
    Custom Script Code
    Local Variables
        WeaponRange = 100 <Integer>
        CamYaw = (Current camera yaw of player Player) <Real>
        CamPitch = (Current camera pitch of player Player) <Real>
        CamHeight = ((Ground height at (Position of PlayerUnit[Player])) + CamHeight) <Real>
        TraceDistance = 0.0 <Real>
        TraceHeight = 0.0 <Real>
        TracePoint = No Point <Point>
        TraceRegion = No Region <Region>
        TraceWorldHeight = 0.0 <Real>
        TargetClosestUnit = No Unit <Unit>
        TargetUnitWorldHeight = 0.0 <Real>
    Actions
        General - For each real TraceDistance from 0.0 to (Real(WeaponRange)) with increment 0.1, do (Actions)
            Actions
                General - If (Conditions) then do (Actions) else do (Actions)
                    If
                        CamPitch < 90.0
                    Then
                        Variable - Set TraceHeight = ((Tan(CamPitch)) * (TraceDistance * -1.0))
                    Else
                        General - If (Conditions) then do (Actions) else do (Actions)
                            If
                                CamPitch > 270.0
                            Then
                                Variable - Set TraceHeight = ((Tan((360.0 - CamPitch))) * TraceDistance)
                            Else
        Variable - Set TracePoint = ((Position of PlayerUnit[Player]) offset by TraceDistance towards CamYaw degrees)
        Variable - Set TraceRegion = (Region(TracePoint, 0.3))
        Variable - Set TraceWorldHeight = (Ground height at TracePoint)
        Variable - Set TargetClosestUnit = (Closest unit to TracePoint in (Any units in TraceRegion owned by player 15 matching Excluded: Missile, Dead, Hidden, with at most Any Amount))
        Variable - Set TargetUnitWorldHeight = (Ground height at (Position of TargetClosestUnit))
        Variable - Set TargetUnit[Player] = No Unit
        Variable - Set TargetPoint[Player] = No Point
        General - If (Conditions) then do (Actions) else do (Actions)
            If
                And
                    Conditions
                        TargetClosestUnit != No Unit
                        (Abs((CamHeight + (TraceHeight - TargetUnitWorldHeight)))) >= 0.0
                        (Abs((CamHeight + (TraceHeight - TargetUnitWorldHeight)))) <= (Custom value 0 of TargetClosestUnit)
            Then
                Variable - Set TargetUnit[Player] = TargetClosestUnit
                General - Skip remaining actions
            Else
                General - If (Conditions) then do (Actions) else do (Actions)
                    If
                        (Abs((CamHeight + TraceHeight))) <= (Ground height at TracePoint)
                    Then
                        Variable - Set TargetPoint[Player] = TracePoint
                        General - Skip remaining actions
                    Else

And then the shooting trigger (no ammo/cooldown added):

Shoot
    Events
        UI - Player Any Player clicks Left mouse button Down.
    Local Variables
    Conditions
        And
            Conditions
                (PlayerUnit[(Triggering player)] is alive) == true
                AttackOnCooldown[(Triggering player)] == false
                W[(Triggering player)] == false
                A[(Triggering player)] == false
                S[(Triggering player)] == false
                D[(Triggering player)] == false
    Actions
        Unit - Make PlayerUnit[(Triggering player)] face (Current camera yaw of player (Triggering player)) over 0.0 seconds
        Variable - Set AttackOnCooldown[(Triggering player)] = true
        Animation - Play Attack animation for (Actor for PlayerUnit[(Triggering player)]) as Default, using No Options options and Default Time blend time
        Traceline((Triggering player))
        General - If (Conditions) then do (Actions) else do (Actions)
            If
                TargetUnit[(Triggering player)] != No Unit
            Then
                Environment - Execute Ghost - C-10 Canister Rifle (Damage) on TargetUnit[(Triggering player)] from PlayerUnit[(Triggering player)]
                Unit - Order TargetUnit[(Triggering player)] to ( Attack targeting PlayerUnit[(Triggering player)]) (Replace Existing Orders)
            Else
                General - If (Conditions) then do (Actions) else do (Actions)
                    If
                        TargetPoint[(Triggering player)] != No Point
                    Then
                        Environment - Execute Ghost - C-10 Canister Rifle (Damage) at TargetPoint[(Triggering player)] from PlayerUnit[(Triggering player)]
                    Else
                        Sound - Play Ghost_AttackLaunch for (All players) (at 100.0% volume, skip the first 0.0 seconds)
                Variable - Set AttackOnCooldown[(Triggering player)] = false

And a list of variables if needed:

        CamHeight = 1.1 <Real>
        TargetUnit = No Unit <Unit[3]>
        TargetPoint = No Point <Point[3]>
        AttackOnCooldown = false <Boolean[3]>

Let me know if you believe I missed something in the coding or if you know of a better way of TPS targeting/attacking. Thanks for any suggestions, all help is greatly appreciated!

Might want to look at this TPS engine. It uses traceline and works.
