Uni Bullet Hell - 2D bullet hell's shot pattern system

Hello.
I have updated to the most recent version in a new project and I'm having some issues with Homing Shot. I have a script that randomly selects a target near the Player and passes its transform to the UbhHomingShot.m_targetTransform.

Here is what happens: Firstly when a new bullet, or missile in this case, is created, it is spawned in at the origin (0, 0, 0) and is then moved to the shot point. This causes an artifact to appear at the origin. You should probably make new bullets be created somewhere off screen or allow the User to set a specific transform for them to be instantiated at.

Edit: I realized that the objects are spawning on the Pooler's transform, so I just moved it away from the origin.

Secondly, randomly, the missile will be removed when it hasn't struck anything. I currently have it's auto remove time set to 5 seconds so this should not be happening. Each player attack is in their own layer so they only collide with enemies, and the missiles will randomly self remove. Not sure what is causing this, I will test some more to make sure it's not something on my end.

 

Hi @WestHill

Is it poosible to implement the feature for homing shot to not fire if there's no designated tag in the scene?

Right now it's kinda wonky, the bullet goes upwards when fired without target, it would be could if it wouldn't fire at all.

 

nice. I will add it.

 

Great, thanks

 

@WestHill
Hi, i'm having a problem where switching scenes gives me only this error

Some objects were not cleaned up when closing the scene. (Did you spawn new GameObjects from OnDestroy?)
The following scene GameObjects were found:
UbhShotManager
UbhTimer

I've already tried calling UbhObjectPool.instance.ReleaseAllBullet() before moving the scene but the problem persists

 

@medellinmario04
I want to find out if the cause of that is the asset.
Can you send me the smallest project that causes the error?

 

Am I the only one having this issue? Been waiting on a reply...

 

@MaximumTre
Can you send me the smallest project that causes the error?

 

@MaximumTre

What does the log say?

 

The log says nothing when the homing bullet vanishes. I decided to use my own homing method because I got tired of waiting for an answer.

 

@MaximumTre
If the cause of the problem is in my asset, I will fix it.
But if it is a problem specific to your project, I can not find it.

Please send me the smallest project if you want me to make that decision.

 

Hello @WestHill

I want to update Uni Bullet Hell, because I'm currently using an old version. In my game, I have created several prefabs each of them with an UbhShotCtrl + shot patterns. Is there a way to update Uni Bullet Hell without corrupting the assets so I don't need to start over? Thanks in advance.

Also:

Coroutines have been deleted, but why example code only?

 

Hey @WestHill any change of updating the asset so the weapons requiring target/tag don't fire when there's no target/tag found?

 

Hello
Could someone tell me what is the best way to desable UBhShotCntrl.Scpipt when Player is dead?

Is it something like this OK?

Code (CSharp):

1.  
2.     private GameObject livePlayer;
3.    public GameObject hellBullet;
4.    // Use this for initialization
5.    void Start () {
6.        livePlayer = GameObject.FindWithTag ("Player");
7.        
8.    }
9.    
10.    // Update is called once per frame
11.    void Update () {
12.        if (livePlayer != null) {
13.            hellBullet.SetActive(true);
14.        }
15.  
16.        if (livePlayer == null) {
17.            hellBullet.SetActive(false);
18.        }
19.    }
20.  

I am not a codder, so is it good for perfomance etc?

 

Since it's just one player object the performance should be fine.

 

thank you for the answer

 

Hello, Great asset. Is there a simple way to have the bullets NOT rotate? I want my bullet's z rotation to remain zero (or the initial angle) even if they are locked-on a target. Thank you.

 

alas but this did not help me. Sometime I steel see error message: "Some objects were not cleaned up when closing the scene. (Did you spawn new GameObjects from OnDestroy?)"
And UbhShotManager and UbhTimer appiares in new scene (where there is no any Bhl scripts). Sometime it could be only UbhShotManager. So is it bug or am I doing something wrong?
Please help me, this asset is really good for my purpos but I can't move further.

 

I'm dealing with that same problem where switching scenes.

EDIT: v1.4.8 fix this issue! Good job.

 

version1.4.8 has been released.

Fixed an issue that OnDestroy error when changing scenes.
*The singleton classes is now DontDestroyOnLoad.

Added "UbhObjectPool.instance.RemoveAllPool()" method to remove all bullet pools.
*If you want to clear the bullet pool when changing scenes, call the above method.

 

Hi , I use "Core GameKit " and do " Enable a definition "USING_CORE_GAME_KIT" in "UbhObjectPool.cs". ",
But I have the Error "Assets/UniBulletHell/Script/Singleton/UbhObjectPool.cs(159,34): error CS0246: The type or namespace name `PoolingParam' could not be found. Are you missing an assembly reference?".
How can I fix it?

 

I will check the latest version of CoreGameKit.

 

@freeze426
version1.4.9 has been released.
This version fixes an error when using CoreGameKit.

 

Thank you , it work very well.
Good job!

 

I stuck with one problem. I make that my bullets can be destroyed by player missile. In this moment bullet instantiates explosion. My problem is that sometimes explosion appears in at the origin (0, 0, 0). (In most cases explosion appears in proper place)
Could someone help me? How can one fix it?

 

@DYV
Bullets is pooled, so when deactivated it moves under PoolManager and resets its position.

If you want to play the effect at the hit position,
get the bullet position before the bullet becomes inactive and play the explosion effect there.

 

thank you for the answer. Here is my code of bullet:

Code (CSharp):

1. public void Hit(int damage)
2.     {
3.  
4.         currentHealth -= damage;
5.  
6.         // If the current health is less than or equal to zero...
7.         if(currentHealth <= 0)
8.         {
9.             // ... the enemy is dead.
10.             Death ();
11.         }
12.     }
13.  
14.  
15.     void Death ()
16.     {
17.  
18.         Instantiate(explosion, transform.position, transform.rotation);
19.         gameController.AddScore (scoreValue);
20.         Destroy (gameObject);
21.     }

As I understand I get bullet position and instantiate explosion before it will be destroyed. Or do you mean something different?

update: I put PoolManager at scene far outside of camera view and now everything looks fine I just wonder if it is OK or better to find another solution..

 

Hi,
I have a scene that have many different power up items dropped dynamically, so I have to change bullet power(damage) at runtime.
How can I change the "Power" value after bullet spawn at runtime?
There's a script "UbhPlayerBullet.cs" has "Power" value on it. Should I change that one?
Any suggestion is welcome.

 

@chihchanglin
The scripts under the Example folder (eg "UbhPlayerBullet.cs") are sample scripts and have minimal functionality.
Please edit them freely.

 

Hello @WestHill

i'm having some issues with callback, i was hoping you could help. I'm sending some callbacks to Playmaker FSM, and it all works fine, however, only with one FSM. In the situation where i have multiple FSMs on the object that has UBH, sending callback to multiple FSM's does not work, events are sent only to one of them, in this case only to first one set to receive the callback.


Image represents how it is set up, but both callbacks are received by FSM1 only.

 

@Oshigawa
I don't have Playmaker so I can't check it.
Can you send me the smallest Unity project (1 scene, 1 component)?

 

Sure.

 

I know the asset is meant for 2D games on either x,y or x,z. However I'm hoping to implement it in my project which is in full 3d (x,y,z).

Is there a way to implement this? And to handle shots as forward, left/right, up/down instead?

I've used this asset in the past and it's perfect! however I decided to move my game from 2D to 3D, and i would like to continue using this asset in the new project.

 

@rrahim
Sorry, this asset is for 2D or 2.5D games, so the axis of movement cannot be changed.

 

I understand. I've already figured out a way to continue using it based on the gameplay of my project.
Do you have any plans to create a 3D Bullet Hell asset?

 

@rrahim
Thanks for the request. but I have no plans at this time.

 

Hi!

I acquired your asset some time ago but just recently I decided to use it in a project.

The problem I´m having, besides the fact that I´m new to C# and game programming is:

I´m using my custom bullet and it has a particle effect in it.

I added a field so i can add this particleSystem and, originally it´s in a gameobject that is disabled

I succeed to make it enable and play the particles when the enemy fires a bullet, but, when it returns to the pool it still enabled...

anyway, here´s the modifications I did to your code, I´d really appreciate for any guidance to solve this issue

Thanks in advance

using UnityEngine;

/// <summary>
/// Ubh bullet for sprite2d and rigidbody2d prefabs.
/// </summary>
public class UbhBulletSimpleModel3d : UbhBullet
{
[SerializeField]
private Rigidbody m_rigidbody3d = null;
[SerializeField]
private Collider[] m_collider3ds = null;
[SerializeField]
private MeshRenderer[] m_meshRenderers = null;
[SerializeField]
private GameObject[] m_gameObjects = null;
[SerializeField]
private ParticleSystem[] m_particles = null;

private bool m_isActive;

/// <summary>

public override bool isActive { get { return m_isActive; } }

/// <summary>

public override void SetActive(bool isActive)
{
m_isActive = isActive;

m_rigidbody3d.detectCollisions = isActive;

if (m_collider3ds != null && m_collider3ds.Length > 0)
{
for (int i = 0; i < m_collider3ds.Length; i++)
{
m_collider3ds.enabled = isActive;
}
}

if (m_meshRenderers != null && m_meshRenderers.Length > 0)
{
for (int i = 0; i < m_meshRenderers.Length; i++)
{
m_meshRenderers.enabled = isActive;
}
}

if (m_gameObjects != null && m_gameObjects.Length > 0)
{
for (int i = 0; i < m_gameObjects.Length; i++)
{
m_gameObjects.SetActive(true);
}
}

if (m_particles != null && m_particles.Length > 0)
{
for (int i = 0; i < m_particles.Length; i++)
{
m_particles.Play(true);
}
}
}
}

 

@lzardo2012
Hi.
Try to rewrite the part of the particle as follows.

Code (CSharp):

1.         if (m_particles != null && m_particles.Length > 0)
2.         {
3.             for (int i = 0; i < m_particles.Length; i++)
4.             {
5.                 if (isActive)
6.                 {
7.                     m_particles[i].Play(true);
8.                 }
9.                 else
10.                 {
11.                     m_particles[i].Stop(true);
12.                     // If you need to clear it.
13.                     // m_particles[i].Clear();
14.                 }
15.  
16.             }
17.         }

 

Hi

Thank you very much!

I´m on my job right now but as soon as I get home I´ll try it out and let you know!

Looks like it´ll work!

 

Yes, it was needed:

m_particles.Clear();

 

Hello @WestHill

This might be a bit out of your scope, but i'm using UBH in conjuction with Core Game Kit, and when i select Persist between scenes in Core Game Kit i get this when i load another scene

Some objects were not cleaned up when closing the scene. (Did you spawn new GameObjects from OnDestroy?)
The following scene GameObjects were found:
UbhTimer
UbhShotManager

But the worst issue is that even if the error is always present, sometimes the UBH is active, sometimes not.

Any ideas how to deal with this persistence problem?

 

@Oshigawa
GameObjects with components that inherit from UbhSingletonMonoBehavior, such as UbhTimer and UbhShotManager, are set to DontDestroy.
They will continue to survive throughout the game, but that's not a problem.
It will be reused when UBH is used again.

If you want to delete it explicitly, you can also use Destroy().
But I don't recommend it.

 

Something weird is definitely going on. I'm using my CGK with don't destroy on load via Persist Between Scenes. Now, i have two main menus, one for startup (which includes CGK), and the other one which is a bootstrap so stuff that uses don't destroy on load doesn't get duplicate (without CGK since it's transferred between scenes).

LevelWaveSettings from CGK is loaded on main menu, and when i load the level it is transferred to the next scene and UBH works ok in most cases, however, sometimes i get the error and the enemies don't fire bullets.



Sometimes the UbhTimer is included in the message too. What is even more confusing is that i sometimes get the error but the enemies ARE firing and everything seems to be working fine.

Also, there occurences when the level loads ok, without errors, and i go back to main menu without errors, back to game without errors and so on. But as soon as there's some firing, i.e. ubhshotmanager activating and i return to main menu afterwards i get the error. I must emphasize that i release all bullets before going back to another scene.

When i get the error when going from main menu to level, UbhShotManager and UbhTimer are DESTROYED, as you can see they're not in the scene.

 

@Oshigawa
Version 1.5.0 was released earlier, so please try to update it.

If version 1.5.0 still has the same problem, can you send me your smallest project?
We need to find out if the problem is in UBH or in the project.

 

Oh shoot, i didn't update. I'll check it out and let you know asap.

 

That sorted it out, thanks.

 

I search that too. Do you have new plans for 3d?

 

@Mike891
I thought about it, but that would be a different asset.
UBH is a 2D asset and is designed for it.

 

Hi @WestHill

Sorry for bugging you, there's another small issue. Sometimes it happens that enemies are firing their bullets at a 90 degree angle. You can see how it looks in the video, all the bullets should move towards the player.

Also, here's a screenshot from the video, with the yellow dotted line being the bullet trajectory which is not good.



I'm using linear lock on shot, i call ubh.StartShotRoutine(), when the shot is fired i call ubh.StopShotRoutineAndPlayingShot().I'm using shotroutine instead of startshot so i don't have to write actions for every shot type.



I do get warnings in the console though:

This bullet is not found in m_bulletList.
This bullet is already added in m_bulletList.

Also, when i click on the object holding the linear shot script i see that the angle is changed to 90 degrees.

Bullets are properly released using UbhObjectPool.instance.ReleaseBullet(ubhbullet, false);

 

@Oshigawa
Hi.
Are there any prefab or in-scene instances of Enemy where the shot angle is 180?
If they are not the cause, send me a minimum project that is reproducible, as I want to investigate.
