Automatic Turret    (Wiremod Required)

Building it:
1. Spawn: 1 Dumpster lid, 1 Sawblade, 1 Locker door and a medium sized FLAT object.
2. Axis the sawblade to the dumpster lid with the sawblade in the very middle.
3. Easy-weld the locker door onto the edge of the sawblade, facing upwards and not touching the dumpster lid.
4. Axis the medium sized FLAT object to the top of the locker door.
5. Set each prop's weight to 1.
6. Put 2 Beacon Sensors on the top and bottom of the front of the medium sized FLAT object.
7. Put another 2 Beacon sensors on the left and right side of the front of the medium sized FLAT object.
8. Add a Target finder with the desired options to it.
9. Link the beacon sensors to the target finder. (With the right click)
10. Add 4 Less Than gates to it.
11. Wire the Less Than gates to the Beacon sensors. A: Left beacon sensor. B: Right Beacon sensor.
12. Add 2 thrusters on the opposite sides of the locker door. (The original article doesn't state what multiplyer, but I'd say about 50-200)
13. Add 2 thrusters on the top and bottom of the
back
of the medium sized FLAT object.
14. Wire the thrusters to the less than gates opposite each other- So Top Thruster -> Bottom less than gate, and Vice Versa.
15. Add a turret (or launcher to the middle of the medium sized FLAT object and use that key to fire (you can build some advanced thing that will fire it automatically but this is just the beginners guide)
16. Have fun with your autotracking turret!
 

3D Tracking Turret   (Wiremod Required)

Creating it

1) First create a wire wheel on the ground.
Model: Oil drum
Torque: 8000
Friction: 10

2) Create another wheel on the side of the oil drum wheel
Model: Car wheel
torque: 2500
Friction: 2
3) Spawn a Beacon sensor on the bottom of one of the polygons on the wheel and spawn a wire Turret just above the Beacon sensor. settings: check the split X,Y,Z
4) Spawn a target finder on the ground, you can insert any settings you want.


How it should look
5) Link the beacon sensor to the target finder by right clicking on the beacon sensor with the beacon sensor tool and then left clicking on the target finder.
6) Choose your physical properties tool (under the "Tools" tab) Set the material to ice and uncheck the gravity box
7) Apply physical properties to all of the parts on the turret
8) Now create 2 arithmetic - sign gates on the ground, Do not put any gate or target finder on the turret because that will make it spass and not working correctly
9) Create 2 Comparison - is in range exclusive gates on the ground
10) Name one of the sign gates to First with the namer tool and name the other one to second. do the same thing with the two in range gates.
11) Create a Logic - And (all) gate on the ground
12) Create a Constant value with 2 values value 1 to 90 value 2 to -90

Wiring it

13) Now for the wiring, Wire the first sign gate's
A
to the beacon sensors
X
input.
14) Wire the Second sign gate's
A
to the beacon sensors
Y
input.
15) Wire the Oil drum wheel's output
Go
to the first sign gate
16) Wire the Car wheel's output
Go
to the second sign gate
17) Wire the first in range gate's
MIN
to constant value of -90 and wire the
MAX
to constant value of 90
18) Do the same thing to the second in range gate
19) Wire the first in range gate's
value
to the beacon sensor
X
input
20) Wire the second in range gate's
value
to the beacon sensors
Y
input
21) Wire the And (all) gate's
A
to the target finder's
output: 1
and the
B
to the first in range gate. and the
C
to the second in range gate.
22) Wire your turret's
Fire
to the and (all) gate.
23) now your ready and your turret should find the closest target and shoot at it.

How it should look when everything is done

Modifications

If you would like to aim the turret with your mouse instead of it aiming by itself you could:
1) Create a airboat seat.
2) Apply the same physical properties as before
3) Easy weld it to the side of the car wheel so it you can see where the turret aims
4) Create a advanced pod controller on the ground and link it to the seat by right clicking on the pod controller and then right clicking on the seat
5) Remove the target finder
6) Take the Beacon sensor tool and link the beacon sensor to the pod controller
7) Wire the pod controller's
crosshair
output to the pod controller's
active
input
8) Now wire the turrets
fire
output to the pod controller's
mouse1
input
9) Now you can aim the turret with your mouse and shoot with your left mouse button
