[RELEASED] Complete Physics Platformer Kit

I had used a capsule collider a while ago but I remember encountering some weird issues with it so I switched it back. Although at the time I was looking to set the player's transform.up based on the slope they were currently walking on (so the player would conform to hills and such) so I think this conflicted with the capsule and I switched back. Granted I didn't end up using that anyway but as of yet, I have yet to see a reason not to use the box collider.

 

On flat ground it's fine but moving up and down on inclines is the reason I can't use a box collider. I even looked at the code for player move and character motor and no mention of specific sizes needed on the collider. Guess I'll keep trying to play with it.

 

I was pretty picky about always seeing the model touching the ground on slopes and such but after playing Mario 3D World and seeing Mario "hover" on stairs (obviously they used a flat slope for the collision on them), I don't feel as bad.

 

I'm alive, just haven't used this kit in a long long time D: Lately I've been just programming my games by myself without using other stuff as starting points. But I still read this thread from time to time XD

 

But I thought you were expanding upon Infection (which didn't Sebastian code)?

 

I'm working on a expanded version of infection, but I discarded Sebastian's coding of it and I'm redoing it all based on the Coop Action Game Kit ;D

I'm also working on 6 small prototypes for school, and one other personal project not ready to show/talk about a local multiplayer vs game.

 

Hi
Any chance to help me have an iOS pad controller without buy anything from store
Thank you

 

You could code your own controls, although I think it'd be much simpler to just buy a pre-made package to do it for you.

 

https://www.assetstore.unity3d.com/en/#!/content/15233
This is free... But you need to know a little bit of programming to implement, not a lot though.

 

Hi everyone, i have started with this kit yesterday, thanks for Daniel for theses addons.
I have a question, when the scene starts, the player starts in a jump state, anyone knows how i can fix this??
it has to start on the ground and not jumping.
thanks in advance for the reply!!

 

Check your animation controller to make sure that "Idle" is the default state. But given the fact he's jumping, I'm willing to bet that you have the player set to start too close to the ground and/or somewhat in the ground. This will force the player up at the scene start. Just raise them off the ground by a bit and it should resolve it.

 

Hello again besus can you give me little idea of water i mean what the idea of particle work when player enter into water i saw in your dev blog and also one more thing how i stop player from moving while punching i m using DanielSnd melee script and thank for great tip about logic

 

No doubt that enemies in this kit are quite basic, so with just a simple Raycast to check what is ahead of them, you can make them seem a bit more intelligent (and less prone to blindly running off of edges).

 

I don't know if this has already been mentioned or not, but just in case... I'm pretty sure line 136 in Throwing.cs is incorrect and it is allowing the character to pick things up even when there is something above their head...

Code (CSharp):

1. if(!Physics.CheckSphere(holdPos, checkRadius, 2))

The comment above this line reads:
//if there is space above our head, pick up item (layermask index 2: "Ignore Raycast", anything on this layer will be ignored)

The last parameter of Physics.CheckSphere is not the index of a layer to ignore, it represents a bitmask of the layers to include. The default value is "DefaultRaycastLayers", which means all layers except the "Ignore Raycast" layer which is exactly the way we want it. In other words, just change it to...

Code (CSharp):

1. if(!Physics.CheckSphere(holdPos, checkRadius))

On a somewhat related note... I know many of you will defend the author to the death but I feel like this kit could use an update. The kit does provide a very good value for the price and its great that the community has pitched in. However I think the bug fixes and some of the additions belong in the source code so people don't have to go digging through 15 pages to find them. Reading through those pages I noticed that there was quite a bit of talk about things getting added/updated, and it is a little disappointing that those things haven't happened.

 

Nice catch! I never even looked in to that statement after having noticed I could still pick up an object while holding one. Instead I did things the "lazy" way and added a "&& if !heldObj" to the OnTriggerStay check.

Actually, I agree with you. Especially with Unity 5 coming out soon. Granted I was able to import the project without issue (only having to change the collider type on the frame object), it would still be nice to see "Unity 5 compatible" going-forward. That and earlier in this thread Greg had even asked Daniel for permission to include his addon scripts in future updates to the kit.

At what point does an asset become abandonware and allow others to improve upon (and sell) it because I would consider replacing it on the asset store (with some of my additions) if the legalities checked-out.

 

hi,

Has anyone rope script for Complete Physics Platformer Kit ?

or trying to implement "QuickRopes Rope Physics"

+++

 

Another bug related to Throwing.js... If you pick up an object and the joint breaks due to exceeding the torque or force limit, heldObj doesn't get set to null and the held object's rigidbody settings don't get reset either. This can lead to a number of issues. For example, if you try to pick up an object again, you end up sort of pushing it because the code thinks you are still holding something and it tries to throw. I haven't decided how to fix that one yet... time for sleep.

 

I ended up using a simple coroutine to keep an eye on the joint...

Code (CSharp):

1.  
2. private IEnumerator heldObjCheck()
3.     {
4.         while (joint != null)
5.         {
6.             yield return new WaitForSeconds(.7f);
7.         }
8.         if (heldObj != null)
9.         {
10.             DropPickup();
11.         }        
12.     }
13.  
14.  

DropPickup is the same as ThrowPickup() except it doesn't play sound or add force. I start this coroutine when an object is picjed up.

 

I think I've only broken a joint once in all of my play-testing. Trying to recreate it now, I just can't seem to.
What would be the simplest way to do so willingly? Ha ha.

 

For example... If you are carrying an object and you walk under a low platform that hits the object you are holding. Common enough scenario in some puzzle platformer type games.

 

Sorry, I guess I introduced this bug myself... That joint is normally unbreakable, which may not be considered a bug, but seems like an oversight at least. If you try to do this with the code as is with a non breakable object, you end up with the carried object bouncing around frantically behind you. So I made the joint breakable.

 

I was going to say, I tried to recreate it just now in the scene view by pulling the object around manually and no matter how vigorously I moved it, the character pulled along with it.

 

Yeah, its funny how a fixed unbreakable joint turns into something more like a springy joint.

 

Hi Besus,

Any chance to share tutorial for grab dynamic object ?

Very nice work indeed

 

hi,

You can mix Throwing.cs and elevator script, i think. Daniel post it, if i remember.

++

 

hi,

anyone has writing a new gui manager script for using new ui system ?


++

 

It's a little more complicated than that.

At the simplest level, I am using the ledge grab code that already exists for static objects and when grabbing on to a dynamic one, I set the players rigidbody speed to match that of the object. It's similar to the code that already exists in the PlayerMove script to help keep the player on moving platforms (only applying it to the y-axis instead of just x/z).

 

Thx Tequyla and Besus, I try it

 

Just finished skimming this entire thread! This stuff is amazing. Me and few of my friends are trying to learn how to build and develop games, and this kit has already been a HUGE help! Thanks to everyone for posting your updates, your scripts, your questions and solutions. This is very exciting!

 

I need some help, all my enemies are super slow if vsync is not on

 

I addressed that issue a few pages ago. It's a result of how the TriggerParent script is written: http://forum.unity3d.com/threads/released-complete-physics-platformer-kit.203279/page-9#post-1735625

 

hi people,

I'm using the climb script DanielSnd provided. Need to change the player's rotation to always facing the ladder. See below.

Thanks

 

http://docs.unity3d.com/ScriptReference/RaycastHit-normal.html
Raycast when they grab on to it and then align the player to the surface normal of the Raycast hit.

 

I tried copying and pasting the script you included and it does not compile, I tried manually changing the script from what you said but got a little lost...

 

Because you are not defining the libraries used.

Here is the complete script:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class TriggerParent : MonoBehaviour
5. {
6.     public string[] tagsToCheck;            //only check for collisions from objects with these tags
7.  
8.     [HideInInspector]
9.     public bool collided, colliding;
10.     [HideInInspector]
11.     public GameObject hitObject;
12.  
13.     //see if anything entered trigger, filer by tag, store the object
14.     void OnTriggerEnter(Collider other)
15.     {
16.         if (tagsToCheck.Length > 0)
17.         {
18.             foreach (string tag in tagsToCheck)
19.             {
20.                 if (other.tag == tag)
21.                 {
22.                     collided = true;
23.                     hitObject = other.gameObject;
24.                     break;
25.                 }
26.  
27.             }
28.         }
29.  
30.         else
31.             return;
32.     }
33.  
34.     void OnTriggerStay(Collider other)
35.     {
36.         if (tagsToCheck.Length > 0)
37.         {
38.             foreach (string tag in tagsToCheck)
39.             {
40.                 if (other.tag == tag)
41.                 {
42.                     colliding = true;
43.                     hitObject = other.gameObject;
44.                     break;
45.                 }
46.  
47.             }
48.         }
49.  
50.         else
51.             return;
52.     }
53.  
54.     void OnTriggerExit(Collider other)
55.     {
56.         if (tagsToCheck.Length > 0)
57.         {
58.             foreach (string tag in tagsToCheck)
59.             {
60.                 if (other.tag == tag)
61.                 {
62.                     colliding = false;
63.                     hitObject = null;
64.                     break;
65.                 }
66.             }
67.         }
68.  
69.         else
70.             return;
71.     }
72.  
73.     void LateUpdate()
74.     {
75.         if (collided)
76.         {
77.             collided = false;
78.             hitObject = null;
79.         }
80.     }
81. }

 

Thanks Soooo much!

 

Hi
I have a problem with asset. Can't download Your asset to Unity5. Show error. With Unity4.6.x everything was ok.
Could You check this ?

 

Hey guys. When I try to download this asset, this is what I get. (I use Unity 4.6.2f1)
Help?

 

Hey Daniel, great work! Thanks a lot for sharing this! This may be a newb question, but how do I change the input for punching from 'z' to something else?

 

http://docs.unity3d.com/Manual/class-InputManager.html

 

------------------------------------------------------------------------------------------------------------------------------------------------------------
3.4.2015 UNITY5 RELEASED and I download your source code in the asset store today. but this temple project can't run this template. this is error message in the console.
------------------------------------------------------------------------------------------------------------------------------------------------------------

Assets/Physics Performer Kit/Physics Platformer Kit/Scripts/EnemyAI.cs(101,32): error CS1061: Type `CharacterMotor' does not contain a definition for `ManageSpeed' and no extension method `ManageSpeed' of type `CharacterMotor' could be found (are you missing a using directive or an assembly reference?)

 

Just in-case no one else has noticed, Unity 5 and the update to PhysX 3.3.0 seems to have broken the grabbing of pushables. The joint breaks immediately, so I updated the break force to Mathf.Infinity and now when you grab it, the player just slowly spins around with the object.

Edit: Found the reason. It has to do with the players locked rigidbody rotation. If you set it to none in the GrabPushable function, they no longer rotate but get "jittery" in trying to rotate. Turning off their rigidbody interpolation (setting it to none) resolves the jitters as well.

 

Had the same bug as Besus above. Reducing the weight of pushable objects mass to something close to 0.8 seems to fix the issue as well.

 

Has anyone tried to use this plugin as a base for a Bolt Engine multiplayer game? I'm having great trouble trying to convert the controls to work with Bolt in the "command / authoritive" Bolt way, due to the modular and fairly complex code in Physics Platformer. For example, there are 4 scripts on your player, that all interact with each other. Has anyone done this?

Thanks!

 

Is there any tutorial on how to create a reverse jump, like in mario? What about ledge grabbing?

 

Hi Besus, first thanks for your reply.
I'm having trouble aligning the player to the ladder. I added the raycast hit but it does nothing.
PlayerLadderClimb.cs DanielSnd provided

Code (CSharp):

1.  
2.         if(ClimbingLadder) {
3.          
4.             //I'll get the vertical axis (Front and back
5.          
6.          
7.             float v = Input.GetAxisRaw ("Vertical");
8.          
9.             RaycastHit hit;
10.          
11.             if(Physics.Raycast(transform.position, Vector3.forward, out hit)){
12.             transform.rotation = Quaternion.FromToRotation(Vector3.forward, hit.normal);
13.             }
14. ...
15. ...
16. ...

am I missing something?

 

Nothing as far as I can tell, unless the FromToRotation isn't playing nicely with it. Try just setting the transform.forward to the hit.normal:

Code (CSharp):

1. transform.forward = hit.normal;

You may need to use -hit.normal instead.

 

thank you very much Besus. It work very well now.
here's the code for others to see

Code (CSharp):

1. void Update () {
2.      
3.  
4.         //If we're not currently climbing, we won't do anything, but if we are...
5.      
6.         if(ClimbingLadder) {
7.          
8.         //I'll get the vertical axis (Front and back
9.          
10.          
11.         float v = Input.GetAxisRaw ("Vertical");
12.          
13.          RaycastHit hit;
14.          if(Physics.Raycast(transform.position, transform.forward, out hit)){
15.          transform.rotation = Quaternion.FromToRotation (transform.forward,
16.         -hit.normal) * transform.rotation;
17. }
18. ...
19. ...

 

is this mobile ready?

 

Not sure if anyone noticed or not, but the higher jump height while pressed in to a corner (against 2 walls) issue is now gone in Unity 5. No need to use the kinematic rigidbody fix I posted a page or to ago if you are using this kit in Unity 5. Hate to say I told you so, but I told you that it was a Unity physics problem.
