[RELEASED] Easy Ropes 2D

Hello everyone,
After publishing my first game ( Bad Blocks ), some devs asked me about some features of the game, so I decided to release my first asset that was also used in the Bad Blocks.
This package can be used to Easily Implement 2D ropes, 2D bridges and
simple system to hold objects with balloon. Ropes can also be used to implement ponytail hair in platform games.

WoW! Good work!

 

There is an error when your package is imported.


Fixed: It was a bad preprocessor directive.


By the way, there are tons of scripts. Do you have any lightweight version that includes ONLY the rope system? You seem to have ropes, and levels, and examples all mixed together.

 

Hello milo, i submitted a new version to assetstore today, this new version will come with better modularization... But all of my packages will still have depedeces of KiltEngine.lib
Best regards

 

CHANGELOG VERSION 1.1.4.5 :

* Fixed minor bugs when trying to cut rope inside Collision triggers
* Refactored Core Hierarchy. Now the asset will have dependece of KiltEngine.lib folder only...
* Added new demo scene. This new scene will show to users how to make an object (like a sword, or an arrow) cut the rope.​

 

CHANGELOG VERSION 1.1.4.6 :

* Fixed Update Cycle of Ropes in Editor Mode
* Fixed NullRef Exception in Editor Mode when recreating LineRenderer Position​

CHANGELOG VERSION 1.1.4.8 :

* Fixed lag problem when trying to enable/disable large ropes.​

 

Hi Deceiver,

In my game I currently have a fast moving object with a "rope" I created attached to it made up of about 40 or so joints and sprites. I had to increase my timestamps in order to make sure all the joints and sprites stay together since the fast moving object they are attached to was tearing the joints apart. My problem is it hurts mobile performance in doing so.

I noticed in your demo your spring node ropes seem to be stretching the texture. Does this mean your ropes are far more efficient than how I made a fake rope out of many joints and sprites as I did in my game?

Basically, I am curious if your rope method is less CPU hungry than manually making a rope with many joints and sprites

 

Hello Flybye, basically i used joints to make the rope too but instead of using one SpriteRenderer per joint i use one LineRenderer in a chunk of nodes.... My rope have special mechanisms to "Speed Up" tensioned ropes so it will not use normal Joint Physics per node to implement Sling Effect. I really dont recommend use a rope with very large amount of joints like you are using... in my package you can set te distance between nodes adding a rope with small amount of joints increasing the speed of your mobile game... without perfoming in game appearence...

Best Regards
KiltAssets

 

CHANGELOG VERSION 1.1.4.9 :

* Fixed crash with new SceneManager in Unity 5.3
* Fixed obsoletes in Unity 5.3​

 

CHANGELOG VERSION 1.1.5.0 :

* Fixed errors in EnumHelper when compiling to Windows Phone 8.1​

 

Hello

I have a question about this great looking extension.

Can a rope length be changed dynamically?

I am looking to implement a winding rope effect as if it were being lowered from a hovering helicopter.

Thank you.

 

Hello DowseTwoSeven.. thanks for your question
I will answer you with a gif:



PS: I really dont recommend do it in realtime because it's not optimized to change amount of nodes every cycle... if you really want to do my tip is: NEVER user ropes with more than 20 nodes and dont change AmountOfNodes too quickly

 

Thank you for your prompt reply.

That looks fine for what I want it for.

Looks as though you have a new customer.

 

Hello All,

I want to call some function when the rope destroy. Can anybody tell me how to do this?

I just want to know how to use callbacks with this system?

 

Hello MobApps,
EasyRopes2D use c# event style to call events... here how to use it:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class MyRopeReceiver : MonoBehaviour
5. {
6.     #region Private Variables
7.  
8.     [SerializeField]
9.     Rope2D m_myRopeInstance = null;
10.  
11.     #endregion
12.  
13.     #region Public Properties
14.  
15.     public Rope2D MyRopeInstance
16.     {
17.         get
18.         {
19.             return m_myRopeInstance;
20.         }
21.         set
22.         {
23.             if(m_myRopeInstance == value)
24.                 return;
25.             UnregisterEvents();
26.             m_myRopeInstance = value;
27.             RegisterEvents();
28.         }
29.     }
30.  
31.     #endregion
32.  
33.     #region Unity Functions
34.  
35.     protected virtual void OnEnable()
36.     {
37.         RegisterEvents();
38.     }
39.  
40.     protected virtual void OnDisable()
41.     {
42.         UnregisterEvents();
43.     }
44.  
45.     #endregion
46.  
47.     #region Rope Event Receivers
48.  
49.     //Receiver for rope event
50.     protected virtual void HandleOnRopeDestroyed(Rope2D p_ropeDestroyed)
51.     {
52.         Debug.Log("Rope Destroyed!!!");
53.         //TODO: Do something here!!
54.     }
55.  
56.     #endregion
57.  
58.     #region Helper Functions
59.  
60.     protected virtual void RegisterEvents()
61.     {
62.         UnregisterEvents();
63.         if(m_myRopeInstance!= null)
64.         {
65.             m_myRopeInstance.OnRopeDestroyed += HandleOnRopeDestroyed;
66.         }
67.     }
68.  
69.     protected virtual void UnregisterEvents()
70.     {
71.         if(m_myRopeInstance!= null)
72.         {
73.             m_myRopeInstance.OnRopeDestroyed -= HandleOnRopeDestroyed;
74.         }
75.     }
76.  
77.     #endregion
78. }
79.

Is it possible to create the rope through code?, It seems to delete my object as soon as a try to add the Rope2D component?

 

Hello Turtle, you can create ropes with code but you must instantiate one of the pre-config rope prefabs... after instantiate you must set the two TackObjects..
Remember, WHEN the rope call the Start() Function it will try to create self so if dont have the TackObjects defined the Rope GameObject will be deleted

Best Regards.

 

Thanks, got it working. Just upgraded to unity 5.4.0 getting some compile errors you might want to check out.

 

Getting these errors in 5.4

Assets/_KILT/_GameCore/Core/_CoreFrameworks/DefinesSystem/GlobalDefinesSystem/GlobalDefinesManager.cs(120,53): error CS0117: `UnityEditor.BuildTargetGroup' does not contain a definition for `GLESEmu'

I'm interested in Easy Ropes 2D but I have a question
Can I create ropes at run - time ? I would like to add slings to my game like player can use rope for pull enemy or object or enemy pull player Can do this?

Thank you

 

Hello buddy, yeah, you can create ropes in real-time.

Best Regard

For anyone in need of the rope cutter trail working with a perspective camera (instead of orthographic).
Replace line 429 in RopeCutterTrail.cs with:

Code (CSharp):

1. Vector3 v_position = CameraThatDrawThisObject.ScreenToWorldPoint(new Vector3(
2.     Input.mousePosition.x,
3.     Input.mousePosition.y,
4.     transform.position.z - CameraThatDrawThisObject.transform.position.z));

Note: It will still work with orthographic, too.

 

Hello, I have problem with ropes.
I trying to Instantiate a rope in real time, when object have collision with balloon I Instantiate a rope
and attach the rope for a two objects, but its looks like in image

 

Unity 2D Physics is unprecise when trying to counteract a force in opposite direction resulted by huge amount of physics 2d joints calculations.
So, to do it you must increase Position Iterations of Physics2D Settings in your unity project.

By doing it you will be able to increase tension of the rope and keep the position stable but it will cost performance in your game.

Go to Position Iteration (in Physics2DSettings) and change the value to something bigger (like 20.. or maybe something greater, like 160) and see that the rope will stabilize.

You must test by yourself the perfect tradeoff between performance and what you want to do.

Best Regards

 

Just brought it.What gonna happen when over 20 nodes and or change AmountOfNodes too quickly?I m gonna make a 2d special agent cat hanging from tall buildings like007 and player can control rope length
