Randomised Patrol Script

[XCess]

The following is a script I created for the second mission in my Invasion series. It will give a squad three randomised waypoints which they will go to in order. Then they will return to a central position (in my mission this is a list trigger) for five minutes. After these five minutes they will conduct another randomised patrol.

The patrol will be carried out inside an 800 metre radius, and was made without the use of a gameLogic or any other object to define the waypoints to keep lag to a minimum (infact I have experience no lag whatsoever)

syntax:
[leaderName,centralName] exec"infPatrol.sqs"

where leadername is the leader of the group (can actually be any member of the group)

where centralName is the name of an object that will define the centre of the patrol area.

Code: [Select]

 hello XCess, seems to work very well, though just noteing the syntax:
[leaderName,centralName] exec"infPatrol.sqs" is just missing the space between the exec and ".   
   also i allways like it when the script includes the syntax at the top, i sometimes get confused because calling the script i would probley forget the "centralName" part of it. but iam not that advanced in scripting !

; [leaderName,centralName] exec "infPatrol.sqs"

Glad you like the script schuler. I don't think you actually need any space between exec and the scriptname string. syntax is in the post. you're welcome to put it into the script too, as well as any other adjustmnts. Remember the credits ;D

Hello,

I am attempting to use this script but I keep coming up with an "unknown operator" message. yet I have the leader of a 3 man squad (his name is leader1) and I have an object (I am using a palm tree named, tree)  and here is the line of code: [leader1,tree] exec"Patrol.sqs"   

I dont understand why this keeps coming up.  please help I am sure it is something silly 

[XCess]

Try renaming the centre object, tree maybe reserved.
Also the following line of code will have to be changed as you are using a smaller group.

?(count units _group) <= 4 : goto"retreat"

Don't know why it's coming up with unknown operator though
