Added to purchase list till I have the money ;P

 

I'm using this for the first time and i'm curious as to if the player uses the different prefabs can you rig them to hit the enemy? Also, Is there anyway to edit the power of each bullet and how much it'll take off of the player?

I see the UbhSimplebullet and i'm wondering if I attach that to the bullet if that'll work if I drop the speed to zero.....

I'm using 2dToolkit and it's not letting me add the normal scripts due to 2DTK using 3d box colliders and I'm not finding anything to edit the damage of the bullets manually via the prefabs or scripts except the player script which won't attach. I'm wondering if i'm stuck using 2d colliders or if there's a way to manually put the bullets into the game.

 

Do you want to add power parameter to the bullet?
Well please add your own script include a power member.

2D collider of UniBulletHell is not required.
It works by replacement the 2D collider to 3D collider.
(In that case, remove the "2D" from the trigger event method and collider event method.)

 

Greetings again,

I'm trying to use the UniBulletHell setup with the Dark Tonic CoreGameKit + Pooling and I'm having a issue with the use of two pools and the UniBulletHell not meshing well with it. (I'm not a programmer by any means)

Is there any way to prevent UniBulletHell from creating it's own pool or using it with another pool set up so that you can use the amazing bullet prefabs you made or if I would have to edit/make my own scripts to do so? I know that the UbhObjectPool is built into the coding but any chance of possible modification?

 

Hi

Sorry I do not have a "Dark Tonic CoreGameKit +".

To replace the object pooling system, please rewrite the "GetGameObject" method and the "ReleaseGameObject" method of "UbhObjectPool.cs".

 

First of all let me say that I absolutely love this package and my, albeit limited, experience with it has been nothing but a pleasure! If I may though, I have a request for possible future versions and one issue that I am experiencing.

In regards to the request, it would be great if you could implement the ability to have the bullets inherit the rotation of their parent on the incase the project this package is being used in is not based on vertical movement. I have already implemented this in my own project, so it is far from critical but would be nice to see as a default option.

The below has been resolved, please see the edit at the bottom of this post for the resolution.
As for the issue that I am experiencing with UniBulletHell, I have a Linear Shot attached to my player and it functions as intended for a varying amount of time and then it degrades into taking longer and longer between shots - to the point where I have experienced delays of >5 seconds between shots. I've attached the settings of both the shot control and shot components, if perhaps you could point out where I might be going wrong?



EDIT:

Shortly after posting this, while I was digging through my scripts I released that my bullet controller was attempting to release the bullets child object to the pool and not the parent; thus never allowing the child to be reenabled by the pool manager.

TL;DR:
I messed up.

 

Hi

Thank you for a request!
I am going to add the global option of XY axis or the XZ axis by update.

About a issue.
When you release a bullet, please exclude a check of UseAutoRelease.
When it becomes ON, a regenerated bullet is released five seconds later.

 

Hi there

Uni Bullet Hell in today's update (ve1.1.2), now supports the 3D world.
You can set the 3D prefabs and select the X-Y axis or the X-Z axis.

Regards

 

hello.
When player move bottom to top quickly, Homing Shot Bullet always go somewhere else(mainly go bottom).
so can I adjust homing level more flexibly?

thank you.

 

Hi
Thank you for the report. I found a problem.
Until the fixed version is released, please wait few days.

 

Hi
Uni Bullet Hell v1.1.4 was released.
Fixed bug of homing shot.
Please check this update.

Unity Asset Store Link

 

It seems good.
thank you.

 

I just bought this system and followed the guide on your website and I can't get any patterns to work. I've followed the instructions on the website perfectly as they are not really that hard. Is there a new way of doing things or am I missing something?

EDIT:

Ignore this. The bullets are super small for some reason.

 

Hi
What do you want to do? What's not work?

 

I got it to work. For some reason, the bullet sprites were very small and I couldn't see them. I thought they weren't rendering, that's how small they were! Thanks.

 

OK!

 

I have a request/suggestion. Homing projectiles should turn to point towards the target. As far as I can tell, they don't do this already, but this would be a nice addition.

 

I believe I have found a bug. I am using the Prefab LinearShot. When the player object has an enemy object ahead of them, and they both remain in one place, the bullets don't move down the screen. They just appear at the spawn point, then vanish. If I move the player however and wait for a moment, the bullets will then travel down screen normally, as long as the player doesn't remain in line with an enemy object.

 

Can we use this plugin for Unity's UI Elements ?

 

It works.
You must place a Gameobject attached with a UbhObjectPool under the UI canvas.

 

Hi West,

I'm using UBH with Core Gamekit, and I noticed that the bullets are not spawned/despawned correctly from the pool.
The enemies' bullets doesn't recycle, and the player's keep instantiating new one. I tried unchecked "allow instantiate more" but some other exceptions are thrown. In just a few minutes the pool becomes too big and bogs the fps way down.

I also tried building your example scene, which also gives poor fps, around 15 fps mark.

 

Hi
Are you enable a definition "USING_CORE_GAME_KIT" in "UbhObjectPool.cs"?
You have to do it if you use the CoreGameKit pooling system.

 

Yup, I did enable the definition. Tried it with the example scene you provided, the Pool Boss object was created but the pool keeps increasing in size.

 

I tried it in ShotShowcase scene(example in asset), but there was no problem.
Can you send me your project by e-mail?

 

Sure, I'll clean up my project a bit. Can you PM me your address?

 

Please send to this. nishioka-h@westhillapps.com

 

It seems I've made a silly mistake, I used different names with the bullets as I assumed that the HitCheck() in UbhDestroyArea was checking against the tag.

Anyways, thanks for the reply. Sorry to bother you.

 

OK!

 

Hi, after updating my 4.6.9 to 4.7 Plugin started give following error :

Assets/UniBulletHell/Example/Script/UbhDestroyArea.cs(54,24): error CS1061: Type `UnityEngine.BoxCollider2D' does not contain a definition for `offset' and no extension method `offset' of type `UnityEngine.BoxCollider2D' could be found (are you missing a using directive or an assembly reference?)

 

Hi
I will submit a fix version for Unity4.7.0.
Please wait for release.

 

Hi
UniBulletHell v1.1.6 has been released. Please check this.

 

Hi,

just a small question, which is actually two small questions.

First, i have to make a ShotCoroutine in UbhShotCtrl.cs public to make it accessible from another script, can i call it in some other way to keep it private?

Here's the code for calling it:

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class PlayerShot : UbhShotCtrl
7.  
8. {
9.  
10.     void Start()
11.  
12.     {
13.  
14.     }
15.  
16.     public void StartShotRoutine(){
17.      
18.     if (Input.GetButton("Fire1"))
19.  
20.     {
21.         StartCoroutine(ShotCoroutine());
22.     }
23.  
24.     }
25. }
26.  

The other question is why won't it work? I unchecked Start On Awake in inspector, and there are no errors in the log.

Here's the inspector

 

Hi
you can use "UbhShotCtrl.StartShotRoutine()" method from the other script.

ex.

Code (csharp):

1. public class PlayerShot : MonoBehaviour
2. {
3.     UbhShotCtrl m_shotCtrl;
4.  
5.     void Start()
6.     {
7.         m_shotCtrl = GetComponent<UbhShotCtrl>();
8.     }
9.     void Update()
10.     {
11.         if (Input.GetButton("Fire1"))
12.         {
13.             m_shotCtrl.StartShotRoutine();
14.         }
15.     }
16. }

 

NullReferenceException: Object reference not set to an instance of an object
PlayerShot.Update () (at Assets/Scripts/PlayerShot.cs:18)

 

You must add component a "PlayerShot" with "UbhShotCtrl" to same GameObject.

 

They are on the same object, i get this:

Coroutine couldn't be started because the the game object 'RandomShot' is inactive!
UnityEngine.MonoBehaviour:StartCoroutine(IEnumerator)
UbhRandomShot:Shot() (at Assets/UniBulletHell/Script/ShotPattern/UbhRandomShot.cs:37)
<ShotCoroutine>c__Iterator18:MoveNext() (at Assets/UniBulletHell/Script/Controller/UbhShotCtrl.cs:122)
UnityEngine.MonoBehaviour:StartCoroutine(IEnumerator)
UbhShotCtrl:StartShotRoutine() (at Assets/UniBulletHell/Script/Controller/UbhShotCtrl.cs:58)
PlayerShot:Update() (at Assets/Scripts/PlayerShot.cs:18)

 

Please send the project by e-mail so I'll check it.

 

Do you think you could add a "N-way Homing" Shot? The homing shot function is wonderful, but I'd really like to see an N-Way version of it. Other than that, this pack is just awesome. Having a lot of fun with it now that I have a good handle on how it works, but I don't want to mess with the code in the files.

 

OK, I will consider adding it to the release in the future.

 

@WestHill

Hello, i need a small bit of info. I'd like to play an animation and sound as the object fires a bullet. What property should i listen to? I see there's a shooting property, but i guess that's not the exact moment of spawning a bullet, but rather the whole state of firing multiple bullets.

Does the shot finished callback events send an event as soon as the bullet is spawned?

 

Hi

If you add a component with OnEnable method to the bullet GameObject,
It is called at the moment the bullet is fired.

 

@WestHill

wouldn't that affect all the ships using the same bullet prefab?

 

@Kruko

Yes, it is.
I plan to add a callback option when shot lines are fired.
Please wait a few days.

 

@WestHill

Much appreciated!

 

I saw this advertised on the front page and it may be what I'm looking for.
A few questions.

Are you able to fire different types of shots?
eg. homing missiles, charge lasers, etc.

Can you get shots that split into multiple shots at a point/s along their path?

Can different shots be collected as powerups and turned on and off by the code?

 

@Kruko

ver1.2.4 has been released.
Added shot fired call back option.

 

@Cereal_Killa
Hi

Homing shots are included, but lasers are not included.

It can not be done with this asset.

Yes, It is possible to switch shots by code.

 

@WestHill

That was quick, thanks for the update!

@Cereal_Killa

If you are using Core Gamekit (but you can do it in code too), you can set a timed despawn which triggers a death prefab which is an empty prefab with attached shot controller which does its thing in shortest possible time and then despawns too.

 

If you shot a projectile emitter through the air with each bullet fired would it not continue emitting, giving the illusion that the large bullets were also firing small bullets?

You could attach the projectile emitter to the bullet prefab.

Just my thoughts on how I would do this..

I'm happy to write the code myself if your system is easily extendable.
You system looked like a good starting point for a spellcrafting system.
