• Connect Team Foundation Service/TFS 2012 with Visual Studio 2010 &amp; Visual Studio 2008

  - by Vishal

  Hello, Microsoft finally released the Team Foundation Service in late October 2012 after its long time in the preview phase. I was already using the TFS Preview which was free but I was happy to see Microsoft releasing the Team Foundation Service also FREE for upto 5 users. Isn't that great news? I know there are bunch of other free source control repositories (Github, Bitbucket, SVN etc.) out there but I somehow like TFS better. Also the other good thing about the final release was that I didn’t had to do any kind of migration of my code from preview to final release version. Just changed the TFS connection URL and it worked like a charm. Anyways, if you are a startup with small team and need some awesome Source Control along with all the good Project Management, Continuous Integration (Build, Test, Deploy), Team Collaboration, Agile/Scrum planning etc. features than Team Foundation Service is your answer. Microsoft has not yet released their pricing for more than 5 users and will be releasing it sometime in early 2013. What if as of now you have a team more than 5 users and you want to use Team Foundation Service, the good news is you can use it for FREE but when they release the final pricing, you will have to transition to the paid plan. Lot of story, getting to the point, connecting to Team Foundation Service with Visual Studio 2012 is straight forward and would work out of the box but it wont for previous versions of Visual Studio. You will have to upgrade to the latest service pack first and than install the forward compatibility pack. (1st : Service Packs & 2nd: Forward Compatibility packs) For Visual Studio 2010: Visual Studio 2010 Service Pack 1. Visual Studio 2010 forward compatibility for TFS 2012 and Team Foundation Service.         For Visual Studio 2008: Visual Studio 2008 Service Pack 1. Visual Studio 2008 forward compatibility for TFS 2012 & Team Foundation Service. Restart your system. Visual Studio 2008 will not work if you only put https://xxx.visualstudio.com. You will have to put your collection name too as shown below.       By the way, it doesn’t matter if you are an Apple Application Developer or Android App Developer, you can still use Team Foundation Service as your source control. Below are few links to connect to Team Foundation Service with other IDEs: Connect Eclipse to Team Foundation Service. Connect XCode to Team Foundation Service. Happy coding. Vishal Mody

• Unable to install Perl Crypt::OpenSSL::RSA module, please help

  - by Willy

  Hi Everyone, I spent several hours but unable to install CPAN Crypt::OpenSSL::RSA module. It's required for Postfix's dkimproxy add-on. What I do is to run the following command in the shell: $ perl -MCPAN -e 'install Crypt::OpenSSL::RSA' When I run this command, several lines displayed and at the end, this is displayed: Checking if your kit is complete... Looks good Warning: prerequisite Crypt::OpenSSL::Random 0 not found.

• glib2 64-bit compile fails on Solaris 10

  - by Aaron

  I'm encountering a problem building glib-2.26.1 on a Solaris 10 box - 64-bit. Goo diligence doesn't turn anything up, but no matter what I do the build fails in the same way. I've tried using the Sun Studio compiler, gcc (SFW) to no avail. When I compile I get the following error: [root@foo glib-2.26.1]$ export CC=/opt/solstudio12.2/bin/cc [root@foo glib-2.26.1]$ export CFLAGS="-m64" ...configure goes normally...

• Fixed and dynamic IPs in ISC DHPD lead to double lease

  - by GorillaPatch

  I would like to have a small dynamic adress part and the most clients are assigned a fixed IP adress. My dhcpd.conf looks like this: use-host-decl-names on; authoritative; allow client-updates; ddns-updates on; # Einstellungen fuer DHCP leases default-lease-time 3600; max-lease-time 86400; lease-file-name "/var/lib/dhcpd/dhcpd.leases"; subnet 192.168.11.0 netmask 255.255.255.0 { ddns-updates on; pool { # IP range which will be assigned statically range 192.168.11.1 192.168.11.240; deny all clients; } pool { # small dynamic range range 192.168.11.241 192.168.11.254; # used for temporary devices } } group { host pc1 { hardware ethernet xx:xx:xx:xx:xx:xx; fixed-address 192.168.11.11; } } The motivation for the pool declaration with deny all hosts comes from the ISC DHCPD homepage http://www.isc.org/files/auth.html This will allow hosts to be first added to the network, where they will receive a temporary IP from the 241-254 adress range and then later write an explicit host declaration. Upon next connect it will receive the right configuration. The problem is that I am getting error messages that 192.168.11.13 has a dynamic and a static lease. I am a bit confused as I expected the pool declaration with deny all clients would not count as dynamic. Dynamic and static leases present for 192.168.11.13. Remove host declaration pc1 or remove 192.168.11.13 from the dynamic address pool for 192.168.11.0/24 Is there a way to have the DHCP server send an DHCPNA to clients if they have a host statement and retain this dynamic range?

• User is trying to leave! Set at-least confirm alert on browser(tab) close event!!

  - by kaushalparik27

  This is something that might be annoying or irritating for end user. Obviously, It's impossible to prevent end user from closing the/any browser. Just think of this if it becomes possible!!!. That will be a horrible web world where everytime you will be attacked by sites and they will not allow to close your browser until you confirm your shopping cart and do the payment. LOL:) You need to open the task manager and might have to kill the running browser exe processes.Anyways; Jokes apart, but I have one situation where I need to alert/confirm from the user in any anyway when they try to close the browser or change the url. Think of this: You are creating a single page intranet asp.net application where your employee can enter/select their TDS/Investment Declarations and you wish to at-least ALERT/CONFIRM them if they are attempting to:[1] Close the Browser[2] Close the Browser Tab[3] Attempt to go some other site by Changing the urlwithout completing/freezing their declaration.So, Finally requirement is clear. I need to alert/confirm the user what he is going to do on above bulleted events. I am going to use window.onbeforeunload event to set the javascript confirm alert box to appear.    <script language="JavaScript" type="text/javascript">        window.onbeforeunload = confirmExit;        function confirmExit() {            return "You are about to exit the system before freezing your declaration! If you leave now and never return to freeze your declaration; then they will not go into effect and you may lose tax deduction, Are you sure you want to leave now?";        }    </script>See! you are halfway done!. So, every time browser unloads the page, above confirm alert causes to appear on front of user like below:By saying here "every time browser unloads the page"; I mean to say that whenever page loads or postback happens the browser onbeforeunload event will be executed. So, event a button submit or a link submit which causes page to postback would tend to execute the browser onbeforeunload event to fire!So, now the hurdle is how can we prevent the alert "Not to show when page is being postback" via any button/link submit? Answer is JQuery :)Idea is, you just need to set the script reference src to jQuery library and Set the window.onbeforeunload event to null when any input/link causes a page to postback.Below will be the complete code:<head runat="server">    <title></title>    <script src="jquery.min.js" type="text/javascript"></script>    <script language="JavaScript" type="text/javascript">        window.onbeforeunload = confirmExit;        function confirmExit() {            return "You are about to exit the system before freezing your declaration! If you leave now and never return to freeze your declaration; then they will not go into effect and you may lose tax deduction, Are you sure you want to leave now?";        }        $(function() {            $("a").click(function() {                window.onbeforeunload = null;            });            $("input").click(function() {                window.onbeforeunload = null;            });        });    </script></head><body>    <form id="form1" runat="server">    <div></div>    </form></body></html>So, By this post I have tried to set the confirm alert if user try to close the browser/tab or try leave the site by changing the url. I have attached a working example with this post here. I hope someone might find it helpful.

• PortForwarding to IIS in Linux

  - by Simon

  Hi, I am trying to set up port forwarding on a linux box to a IIS webserver on my internal network. The web server sits on Windows 2003 Server. My linux box has eth0 - Internet connection eth1 - internal subnet (10.10.10.x) eth2 - 2nd internal subnet (129.168.0.x) dhcp interface my webserver is on the eth2 interface (192.168.0.6) I am doing port forwarding for port 80 with no avail. I use the same set of rules to port forward to a different webserver and it works. The webapplication is available on the internal network but not for external users. iptables -t nat -A PREROUTING -p tcp -i eth0 -d $PUBLIC_IP --dport 80 -j DNAT --to 192.168.0.6:80 iptables -A FORWARD -p tcp -i eth0 -o eth2 -d 192.168.0.6 --dport 80 -m state --state NEW -j ACCEPT iptables -A FORWARD -t filter -o eth0 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT iptables -A FORWARD -t filter -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE Any Ideas?

• Linux IPTables / routing issue

  - by Jon

  Hi all, EDIT 1/3/10 22:00 GMT - rewrote some of it after further investigation It has been a while since I looked at IPtables and I seem to be worse than before as I can not seem to get my webserver online. Below is my firewall rules on the gateway server that is running the dhcp server accessing the net. The webserver is inside my network on a static IP (192.168.0.98, default port). When I use Nmap or GRC.com I see that port 80 is open on the gateway server but when I browse to it, (via public URL. http://www.houseofhawkins.com) it always fails with a connection error, (nmap cannot connect and figure out what the web server is either). I can nmap the webserver and browse to it just fine via same IP inside my network. I believe it is my IPTable rules that are not letting it through. Internally I can route all my requests. Each machine can browse to the website and traffic works just fine. I can MSTSC / ssh to all the webservers internally and they inturn can connect to the web.

The network looked something like this: I have now replaced the sky modem with a dlink modem which gives the IP to the gateway server that now does the DHCP. It looks like: The internet connection is a standard broadband connection with a dynamic IP, (use zoneedit.com to keep it updated). I have tried it on each of the webservers(one Ubuntu Apache server and one WS2008 IIS7). I think there must also be an issue with my IPTable rules as it can route to my win7 box which has the default IIS7 page and that would not display when I forwarded all port 80 to it. I would be really grateful for any and all help with this. Thanks Jon

• Exim forwards not going out through TLS

  - by Blake

  I'm trying to get Exim to use STARTTLS to send emails that are just FORWARDS. I have a server accepting email at example-accepting.com for users. So I want [email protected] to forward all email to [email protected]. If I do this from the command like on example-accepting.com... echo "test" | mail -s "ssl/tls test" [email protected] Success!! Sent via TLS BUT, if I send an email to [email protected] the forward fails, it's NOT being sent via TLS. I've tried both forwarding the email via /etc/aliases and the user .forward file. The email is indeed sent, but NOT via TLS. Why is it when I run "mail" from the command like it's working like it should, but a .forward is not using TLS? Thanks

• Procmail Mailing List (With Access Control)

  - by bradlis7

  This seems like it should be fairly easy to do, but I've run into a few problems. I've added a cron job to parse all users whose UID is greater than 5000: * * * * * root /usr/bin/test /etc/passwd -nt ~allusers/.forward \ && /bin/egrep '([5-9]|[0-9]{2})[0-9]{3}' /etc/passwd | /bin/grep -v 65534 \ | /bin/cut -d ':' -f 1 > ~allusers/.forward Then I created a .procmailrc file: VERBOSE=yes LOGFILE=/var/log/procmailrc #Allow only certain users to send :0 * ^From.*[email protected].* {} :0E /dev/null But, the .forward file is processed before it even gets to procmail, evidently. If I moved the .forward file to another filename, can I use it in procmail to send an email to the users in this file?

• tap interfaces always disabled in linux bridge

• SSH not working over IPSec tunnel (Strongswan)

  - by PattPatel

  I configured a small network on a cloud virtual machine. This virtual machine has a static IP address assigned to eth0 interface that I'll call $EXTIP. mydomain.com points to $EXTIP. Inside, I have some linux containers, that get their ip through DHCP in the Subnet 10.0.0.0/24 (i called the virtual interface nat ). They run some services that can be reached through DNAT.

• Ubuntu cannot access internet, LAN is fine

  - by Kevin Southworth

  I have an Ubuntu 8.04 LTS server that is directly connected to our Comcast Business Gateway modem and I have configured it with 1 of our 5 allotted Static IPs. My other machines on our LAN can connect to this server (via ssh, web, ping, etc.) but I cannot access this server from outside our network, and this machine cannot get out to the internet either (ping google.com fails with unknown host). Here is my /etc/networking/interfaces file: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 173.162.54.19 netmask 255.255.255.248 broadcast 173.162.54.23 gateway 173.162.54.22 and my /etc/resolv.conf: nameserver 68.87.77.130 nameserver 68.87.72.130 output from sudo route -n: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 173.162.54.16 0.0.0.0 255.255.255.248 U 0 0 0 eth0 0.0.0.0 173.162.54.22 0.0.0.0 UG 100 0 0 eth0 I have a Windows 2008 machine with an almost identical Static IP, static DNS setup and it works correctly, can access it within the LAN and also from public internet, the Windows machine and the Ubuntu machine are both directly connected to the Comcast Business Gateway.

• Two DHCP Servers, Block Clients for one of them?

  - by Rilindo

  I am building out a kickstart network that resides on a different VLAN uses its own DHCP server. For some reason, my kickstart clients kept getting assign IPs from my primary DHCP server. The way I have it set up is that I have a primary DHCP server on this router here: 192.168.15.1 Connected to that DHCP server is a switch with the IP of 192.168.15.2. My kickstart (Scientific Linux) server is connected to that switch on two ports: Port 2 - where the kickstart server communicates to the rest of the production network via eth0. The IP assigned to the server on that interface is 192.168.15.100 (on eth0). The details are: Interface: eth0 IP: 192.168.15.100 Netmask: 255.255.255.0 Gateway: 192.168.15.1 Port 7 - has it's own VLAN ID (along with port 8). The kickstart server is connected to that port with the IP of 172.16.15.100 (on eth1). Again, the details are: Interface: eth1 IP: 172.16.15.100 Netmask: 255.255.255.0 Gateway: none The kickstart server runs its own DHCP server and assigns them over the eth1. Most of the kick starts are built over the kickstart VLAN through port 8. To prevent the kickstart DHCP server from assigning addresses over the production network, I have the route setup like so: route add -host 255.255.255.255 dev eth1 At this point, the clients kept getting assign IPs from the 192.168.15.1 DHCP server. I need to figure out a way to block client requests from reaching that DHCP. Its should be noted that but I also build KVM hosts on the kickstart server as well, so I need those KVMs to have the ability to get DHCP requests from the 192.168.15.1 DHCP server via the bridge network once I finish resolved this particular problem. (Currently, they communicate via NAT). So what would be done to resolve this? Through iptables or some sort of routing I need to put in? I tried to limited to requests via IPtables on that interface, allowing DHCP requests for 172.16.15.x network: -A INPUT -i eth1 -s 172.16.15.0/24 -p udp -m udp --dport 69 -j ACCEPT -A INPUT -i eth1 -s 172.16.15.0/24 -p tcp -m tcp --dport 69 -j ACCEPT -A INPUT -i eth1 -s 172.16.15.0/24 -p udp -m udp --dport 68 -j ACCEPT -A INPUT -i eth1 -s 172.16.15.0/24 -p tcp -m tcp --dport 68 -j ACCEPT -A INPUT -i eth1 -s 172.16.15.0/24 -p udp -m udp --dport 67 -j ACCEPT -A INPUT -i eth1 -s 172.16.15.0/24 -p tcp -m tcp --dport 67 -j ACCEPT And rejects assignments on eth1 from 192.168.15.x network: -A FORWARD -o eth1 -s 192.168.15.0/24 -p udp -m udp --dport 69 -j REJECT -A FORWARD -o eth1 -s 192.168.15.0/24 -p tcp -m tcp --dport 69 -j REJECT -A FORWARD -o eth1 -s 192.168.15.0/24 -p udp -m udp --dport 68 -j REJECT -A FORWARD -o eth1 -s 192.168.15.0/24 -p tcp -m tcp --dport 68 -j REJECT -A FORWARD -o eth1 -s 192.168.15.0/24 -p udp -m udp --dport 67 -j REJECT -A FORWARD -o eth1 -s 192.168.15.0/24 -p tcp -m tcp --dport 67 -j REJECT Nope. :(

• DNS caching server config problem

  - by Alex

  I have a Bind DNS caching-only server setup that is working. I am bringing up a new AD domain controller that will also be a DNS server for that AD but I don't want it responding to any DNS queries except those that are AD related. So, my goal is to leave this caching server as the primary DNS server for stations on the network and have it forward requests for the AD domain to the domain controller. My understanding is that I just need a forward zone for that domain pointing to the domain controller. However it does not seem to be working. So that leaves me to think that my caching server is not forwarding properly. For example, this AD is going to have a naming convention of hostname.mydomain.local. If I do an nslookup and specify the domain controller's IP address as the server, I can query addresses that exist in DNS on that server, such as dc1.mydomain.local. However, queries to my caching server times out (I get a response from the caching server if I query mydomain.local but none of the objects in that domain). Any suggestions? Here is my named.conf file: options { directory "/var/named"; listen-on { 192.168.0.14; 127.0.0.1; }; forwarders { ; ; }; forward first; }; zone "." in { type hint; file "db.cache"; }; zone "0.0.127.in-addr.arpa" in { type master; file "db.127.0.0"; }; //forward zone for mydomain.local zone "mydomain.local" { type forward; forwarders { 192.168.1.21; }; };

I've configured the Bind DNS to forward DNS requests for the domain xyz.lab to the Windows DNS server with this config: zone "xyz.lab" { type forward; forward only; forwarders { x.x.x.x; }; }; zone "x.x.x.in-addr.arpa" { type forward; forward only; forwarders { x.x.x.x; }; }; And Bind options are (the all_internal acl includes the subnets of both the production and lab networks as well as the loopback of the bind server): allow-query { all_internal; }; allow-recursion { all_internal; }; allow-transfer { none; }; notify no; minimal-responses yes; version "unknown"; Unfortunately, when I do an nslookup or dig on the bind server for a host on the lab domain, the request times out. The logs on the Windows 2008 DNS server show it receiving the query and responding to it and a network packet trace shows the query responses arriving at the Bind DNS server. The servers reside on the same switch with a router providing connectivity between the layer 3 subnets (production and lab are on different subnets) and there is a round trip time of between 3ms and 5ms on pings between the two servers, so I don't think there is an issue with latency causing a timeout of the query. In summary a query-response arrives back at the Bind server and the nslookup/dig times-out. Why does the Bind DNS not seem to be doing anything with the query responses when it receives them?

• Configure server on network to analyze traffic

  - by Strajan Sebastian

  I have the following network: http://i.stack.imgur.com/rapkH.jpg I want to send all the traffic from the devices that connect to the 192.168.0.1 router to the 192.168.10.1 router(and eventually to the Internet), by passing through the server and an additional router. Almost 2 days have passed and I can't figure what is wrong. While searching on the Internet for some similar configuration I found some articles that are somehow related to my needs, but the proposed solutions don't seem to work for me. This is a similar article: iptables forwarding between two interface I done the following steps for the configuration process: Set static IP address 192.168.1.90 for the eth0 on the server from the 192.168.1.1 router Set static IP address 192.168.0.90 for the eth1 on the server from the 192.168.0.1 router Forwarded all the traffic from 192.168.0.1 router to the server on eth1 interface witch seems to be working. The router firmware has some option to redirect all the traffic from all the ports to a specified address. Added the following rules on the server(Only the following, there aren't any additional rules): iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT I also tried changing iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT into iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT but still is not working. After adding the following to enable the packet forwarding for the server that is running CentOS: echo 1 /proc/sys/net/ipv4/ip_forward sysctl -w net.ipv4.ip_forward = 1 After a server restart and extra an extra check to see that all the configuration from above are still available I tried to see again if I can ping from a computer connected to 192.168.0.1/24 LAN the router from 192.168.1.1 but it didn't worked. The server has tshark(console wireshark) installed and I found that while sending a ping from a computer connected to 192.168.0.1 router to 192.168.1.1 the 192.168.0.90(eth1) receives the ping but it doesn't forward it to the eth0 interface as the rule tells: iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT and don't now why this is happening. Questions: The iptables seem that don't work as I am expecting. Is there a need to add in the NAT table from iptables rules to redirect the traffic to the proper location, or is something else wrong with what I've done? I want to use tshark to view the traffic on the server because I think that is the best at doing this. Do you know something better that tshark to capture the traffic and maybe analyze it?

• what are the following keyboard shortcuts in a terminal?

  - by kloop

  I am trying to figure out a few keyboard shortcuts in a terminal in mac osx (and Linux): In the command line: go to the next word go to the previous word go to the end of the line go to the beginning of the line This will make it easier to change commands.. Right now, I am using the left/right arrow keys, which is time consuming. I used bind -p as suggested below. EDIT: What do the following key bindings mean? "\e\e[D": backward-word "\e[1;5D": backward-word "\e[5D": backward-word "\eb": backward-word and: "\e\e[C": forward-word "\e[1;5C": forward-word "\e[5C": forward-word "\ef": forward-word

• (Quaternion based) Trouble moving foward based on model rotation

  - by ChocoMan

  Using quaternions, I'm having trouble moving my model in its facing direction. Currently the model moves can move in all cardinal directions with no problems. The problem comes when I rotate the move as it still travelling in the direction of world space. Meaning, if I'm moving forward, backward or any other direction while rotating the model, the model acts like its a figure skater spinning while traveling in the same direction. How do I update the direction of travel proper with the facing direction of the model? Rotates model on Y-axis: Yaw = pController.ThumbSticks.Right.X * MathHelper.ToRadians(speedAngleMAX); AddRotation = Quaternion.CreateFromYawPitchRoll(yaw, 0, 0); ModelLoad.MRotation *= AddRotation; MOrientation = Matrix.CreateFromQuaternion(ModelLoad.MRotation); Moves model forward: // Move Forward if (pController.IsButtonDown(Buttons.LeftThumbstickUp)) { SpeedX = (float)(Math.Sin(ModelLoad.ModelRotation)) * FWDSpeedMax * pController.ThumbSticks.Left.Y * (float)gameTime.ElapsedGameTime.TotalSeconds; SpeedZ = (float)(Math.Cos(ModelLoad.ModelRotation)) * FWDSpeedMax * pController.ThumbSticks.Left.Y * (float)gameTime.ElapsedGameTime.TotalSeconds; // Update model position ModelLoad._modelPos += Vector3.Forward * SpeedZ; ModelLoad._modelPos += Vector3.Left * SpeedX; }

• Moving player in direciton camera is facing

  - by Samurai Fox

  I have a 3rd person camera which can rotate around the player. My problem is that wherever camera is facing, players forward is always the same direction. For example when camera is facing the right side of the player, when I press button to move forward, I want player to turn to the left and make that the "new forward". My camera script so far: using UnityEngine; using System.Collections; public class PlayerScript : MonoBehaviour { public float RotateSpeed = 150, MoveSpeed = 50; float DeltaTime; void Update() { DeltaTime = Time.deltaTime; transform.Rotate(0, Input.GetAxis("LeftX") * RotateSpeed * DeltaTime, 0); transform.Translate(0, 0, -Input.GetAxis("LeftY") * MoveSpeed * DeltaTime); } } public class CameraScript : MonoBehaviour { public GameObject Target; public float RotateSpeed = 170, FollowDistance = 20, FollowHeight = 10; float RotateSpeedPerTime, DesiredRotationAngle, DesiredHeight, CurrentRotationAngle, CurrentHeight, Yaw, Pitch; Quaternion CurrentRotation; void LateUpdate() { RotateSpeedPerTime = RotateSpeed * Time.deltaTime; DesiredRotationAngle = Target.transform.eulerAngles.y; DesiredHeight = Target.transform.position.y + FollowHeight; CurrentRotationAngle = transform.eulerAngles.y; CurrentHeight = transform.position.y; CurrentRotationAngle = Mathf.LerpAngle(CurrentRotationAngle, DesiredRotationAngle, 0); CurrentHeight = Mathf.Lerp(CurrentHeight, DesiredHeight, 0); CurrentRotation = Quaternion.Euler(0, CurrentRotationAngle, 0); transform.position = Target.transform.position; transform.position -= CurrentRotation * Vector3.forward * FollowDistance; transform.position = new Vector3(transform.position.x, CurrentHeight, transform.position.z); Yaw = Input.GetAxis("Right Horizontal") * RotateSpeedPerTime; Pitch = Input.GetAxis("Right Vertical") * RotateSpeedPerTime; transform.Translate(new Vector3(Yaw, -Pitch, 0)); transform.position = new Vector3(transform.position.x, transform.position.y, transform.position.z); transform.LookAt(Target.transform); } }
