Rope attachment scripting basics

[CarlGustaffa]

Why can we reassign nil in the first place? Wouldn't it be better to use nil as a standard dummy, and have nil itself be as locked down as constant numbers?

Because any scripting command in the game can be overriden by a variable. And yes, it would probably be better if it would not be possible at all, perhaps suggest at CIT.

Numbers cannot, so

0 = this spawn something;

is fine too

[CarlGustaffa]

Hehe, they do? Never realized that, not even by accident.

Created the ticket for ya; plz voooooote

Done Hmm, "by design", interesting.

Here is how I believe the length of ropes are controlled.

RopeUnwind

To change the length of a rope, use the ropeUnwind command:

Description:
Spoiler:

show spoiler

ropeUnwind [ropeObject,Speed,Desired Length,(Relative)];

• RopeObject points to the rope itself. After creation it can be referenced in other script commands.
• Speed. Number . Sets how fast the length will change.
• Desired Length Number. How long to make the new length.
• (Relative) Boolean. If set to true, Desired length defines how much longer or shorter to make the rope relative to it's current length.
  

Simple usage example:
Spoiler:

show spoiler

ropeUnwind [ myrope,1,10,true];

This will make the rope object myrope 10m longer.

ropeUnwind [ myrope,1,10,false];

This will make the rope myrope 10m long.

Is it possible to start the mission with rope attached to the helicopter and no cargo? How would one specify the length of the rope? I've been able to get a 150 feet line a few times by using: (heli1 distance cargo1) < 45
It would be a bit more realistic to have to start with the rope empy, although it doesn't behave very well empty when its 150 feet.

Here is how I believe objects can be atached to ropes.

RopeAttachto

To attach created rope to an object, use the ropeAttachto command:

Description:
Spoiler:

show spoiler

[object,position] ropeattachto ropeObject;

• ObjectThe object you want to connect to the end of the rope.
• position. Where on the object to attach the rope to. May have other options such as mempoints?
• ropeObject Rope object created using the alternative syntax.
  

Simple usage example:
Spoiler:

show spoiler

Using the alternate syntax to create a rope below will create a rope 30m long with 10 segments the true means it will unroll. Attached to myheli.

myRope = ropecreate [myheli ,"slingload0",10,30,true];

[mycargo,[0,0,0]] ropeAttachTo myRope ;

This will connect the rope myrope to the mycargo object at it's [0,0,0] point.

Below place in an initialization field of a helicopter place an object nearby named mycargo.
Will create a rope which will unroll out of the helicopter, then after ten seconds will attach to the object mycargo.
Spoiler:

show spoiler

si1 = [this] spawn
{
	_plane = _this select 0;
	_myRope = ropecreate [_plane ,"slingload0",10,30,true];
	sleep 10;
	[mycargo,[0,0,0]] ropeAttachTo _myRope ;


};

RopeCut

To cut a rope, use the ropeCut command:

Description:
Spoiler:

show spoiler

ropeCut [ropeObject,number];

• ropeObject Rope object that has been created.
• number. Where to cut the rope in metres from the helicopter.
  

Simple usage example:
Spoiler:

show spoiler

ropeCut [myrope,10];

Will cut a rope named myrope leaving 10 metres attached to the helicopter.

Note these are just the aspects I have gotten to work. Other syntax options may be possible.

[LeftSkidLow]

Damn you're good.

[Thromp]

Just to save confusion from Blakeace post

myRope = ropecreate [myheli ,"slingload0",10,30,true];

ropeCut [my_rope,10];

above should be

ropeCut [myrope,10];

< change is my_rope to myrope for variable name of rope consitency in example
