[RELEASED] Corgi Engine - Complete 2D/2.5D Platformer [new v8.0 : advanced damage system]

Ok, thank you very much!! I will learn about how to use blend trees. I appreciate it!!!!!

 

Hello, I need your help, my friend.
After adding the "Character Persistence" component to my character, I made a temporary game and selected "Restart Level". Then I was surprised to find that there were two characters in one scene.

 

@Dumpling007 > I'd need a bit more info about what exactly you did, and in what context, to be able to tell what you may have done wrong.
Here are repro steps that work, if your issue persists, don't hesitate to use the support form and provide similar ones :
- fresh install of CE 8.3.1 on 2019.4.40f1
- open MinimalLevel
- edit the Rectangle prefab, add a CharacterPersistence ability to it, press play in the editor
- press escape, then press the RestartLevel button, there's only one Rectangle in the scene

 

Hello @reuno I want to add and Dead Event to a Enemy, so when the enemy dies, I could catch Death Event and drop a key. So I try with Health Script, but I din't see like and status or and a DeathEvent. I try with MMStateMachine, but I don't know how to use it. So please give me a hand, How could I Trigger Death Event in a specific Enemy and send the enemy gameobject reference. Also I want to know why HealthDeathEvent is not available in the Engine?, same happend with CorgiEngineEventTypes, some options are not included in the enum.

Thank you!

 

@xacarana > You can listen to HealthDeathEvents to know when anything dies. There's no need for you to "add" them, they're already triggered.

I do not know what you mean when you say "I want to know why HealthDeathEvent is not available in the Engine?, same happend with CorgiEngineEventTypes, some options are not included in the enum.", you'll have to be more specific.

 

Thank you for a quikly reply, I have this code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using MoreMountains.CorgiEngine.HealthDeathEvent;
5. using MoreMountains.CorgiEngine;
6. using MoreMountains.Tools;
7.  
8. public class EstadoEnemigo : MonoBehaviour, MMEventListener<HealthDeathEvent> {
9.  
10.         public virtual void OnMMEvent(HealthDeathEvent e)
11.         {
12.         // here we start a coroutine that will display our achievement
13.             Debug.Log(e);
14.         }
15.         void OnEnable()
16.         {
17.             this.MMEventStartListening<HealthDeathEvent>();
18.         }
19.         void OnDisable()
20.         {
21.             this.MMEventStopListening<HealthDeathEvent>();
22.         }
23.  
24. }
25.  

And I recibe this compiler error:

Assets/Juego/Scripts/EstadoEnemigo.cs(4,33): error CS0234: The type or namespace name `HealthDeathEvent' does not exist in the namespace `MoreMountains.CorgiEngine'. Are you missing an assembly reference?

I don't know why.

Thank you!

 

@xacarana > I don't know why either, that's unfortunately not enough info to tell. My guess would be you're trying to access this from a place under an asmdef that doesn't have access to it?
If your issue persists, don't hesitate to send more info on how to repro your issue via the support form.
These steps will work :
- fresh install of CE 8.3.1 on 2019.4.40f1
- add the following script outside of the CorgiEngine folder
- it works

Code (CSharp):

1. using MoreMountains.CorgiEngine;
2. using MoreMountains.Tools;
3. using UnityEngine;
4.  
5. public class Test : MonoBehaviour, MMEventListener<HealthDeathEvent>
6. {
7.     public virtual void OnMMEvent(HealthDeathEvent deathEvent) { Debug.Log(deathEvent.AffectedHealth.name); }
8.     void OnEnable() { this.MMEventStartListening<HealthDeathEvent>(); }
9.     void OnDisable() { this.MMEventStopListening<HealthDeathEvent>(); }
10. }
11.  

 

Hi @reuno, I thought the problem is I am usign a old version of unity, the thing is update CorgiEngine is not an option, so my engine code it's old.

My solution would me be, add an Script and use OnDisable method, then i'll trigger a MMGameEvent and I'll catch this Event in other Script.

Code (CSharp):

1. private Health health;
2.     void Start(){
3.         health = this.GetComponent<Health>();
4.     }
5.  
6.     void Update(){
7.                //CurrentHealth is the same when the enemy dies
8.         Debug.Log(health.CurrentHealth);
9.     }
10.  
11.     void OnDisable(){
12.         Debug.Log("Fire Event Here");
13.     }

Please, I want to know why, CurrentHealth didn't change when the enemy dies. Also would be nice if you could share a script to know how to use propertly a StateMachine, I was reading it is an option to events, but the T syntaxis was a little tricky for me.

Thank you for your time,

 

@xacarana > I'm not sure why you'd use a MMGameEvent in this case, it's not what they're used for. I'd recommend just creating your own (or ideally updating to a more recent version of Unity/CE).

 

@reuno I have to use and old version, because in classroom we don't have an updated version of unity because the lincense. So the option is use MMGameEvent, I know that seems like I'm using a pirate version of corgi, but is not, I could send you, a print screen of my purchase of your assets. So please, I still want to know if you have a script for State Machine, because that we could help use.

Thank you!

 

@xacarana > It does indeed sound very sketchy. I don't know what you mean by "a script for state machine" in that context, or how it would apply to your question. I don't think that's the solution to your issue. As I said in my previous message, I'd recommend creating your own event. If your issue persists, please use the support form.

 

Hi everyone ! I'm working on a multiplayer game and I have an issue with key to open door. I've created inventory for both players like in example scene and it works fine. When a player grab the key, it appears in right inventory. My issue is when I want to open the door. If it is player1 which grab the key, door open perfectly but if it is player2, impossible to open door even if he has the right key in his inventory... Any idea ? Thanks a lot for your help !

 

@Marboul > Answered you on Discord already, but just in case, here are steps that will work :
- fresh install of CE 8.3.1 on 2019.4.40f1
- open FeaturesKeys demo scene, move the chest and a yellow key close to the starting area
- add a new InputManager in the scene, set its PlayerID to Player2
- add a new RectangleWithInventory to the scene, name it Player2, set its PlayerID to Player2
- duplicate MainInventory, set its PlayerID to Player2
- press play, using Player2, grab the key, open the chest

 

Thanks a lot @reuno it was not working on my game like that. But I manage to make it works by attributing same inventory to both players. As it is a cooperation game, it works fine like that.

 

Heya folks,

I'm using the latest version of Corgi Engine and I wondered what would be the best thing to achieve this.
I have a corgi player character which I can move around and jump and whatnot. Now for accessibility I would like the player to be able to also use a mouse for movement, meaning when they click on the ground the player character should move to that point.

What would be the best way of implementing that? How do I basically "remote control" a player corgi character?
With an AI as part of the player character? If so, will that introduce any problems? Or is there a better way?

 

@BTStone > That would require implementing pathfinding, and basically an AI on top of that that would take decisions based on your rules. You can't have a character be an AI and a Player, in this case that'd be an AI (that can still have the Player tag if you want).

I hope you'll like this new update, and see you soon for the next one!

 

This is a rudimentary question, but I have two questions.
Both are about animator and mecanim.
As for the animation, I am using 2D in Spine.
Maybe that has something to do with it.

1
When using AnyState, the previous animation always plays to the end before switching to the next one.
If I use arrows to connect the states to each other, the animation plays well, but it doesn't work for the AnyState related animation.
The "Has Exit Time" checkbox is set to false.

2
When running toward a wall, the animators set in running and grounded are switched at high speed and the animator starts to wriggle.
At first I didn't understand the significance of grounded and didn't set it, but I did so because the previous animation keeps playing at places where idle is not turned on, such as the edge of a diagonal column.
Is there a way to address this?
Also, is there a priority order mentioned anywhere when multiple conditions like Idle and Grounded are true?

Thank you in advance for your help.

 

How do I make both the player and enemy AI look like they are leaning along their legs when the ground is slanted?
Sorry if this is a known question.

 

I felt that the English was out of order.
I am translating at DeepL so I apologize if the language is unnatural.

What I wanted to ask is the following.

When the ground is tilted, I want the character to look natural and in line with the ground.
To give an exact example, a human figure would look like it has both feet exactly on the tilted ground.

Sorry for the multiple questions.
Thank you in advance for any help you may be able to provide.

 

@DimJohnDoe > You'll probably have more luck asking the Mecanim or Spine people, most of these are unrelated to the engine.
1. I'd recommend avoiding "any state" patterns until you have a better understanding of how to setup animations, it's certainly harder to setup.
2. Priority order for conditions is top to bottom. I don't know what "high speed switch" you're referring to, if that issue persists, please provide repro steps for it via the support form.
3. Create a class to detect "slanted ground" and update an animation parameter for it? You could also implement feet IK.

 

Hello, Reuno

What should I do if I want to jump from a scene using "Corgi Engine components" to an original scene "without Corgi Engine components"?

Because the Corgi Engine has some elements that are not destroyed along with the scene, this can result in some errors

For example: I want to jump from a Corgi Demo scene to a scene like RPG MV scene

I don't know if I made my question clear

 

@Dumpling007 > You can simply load your scene and unload the contents of DontDestroyOnLoad if you don't need to keep them around.

 

Can I add a criterion to decide when to destroy or keep？Can you tell me exactly what to do, like if I need to inherit a class to rewrite a custom method or something？

 

@Dumpling007 > I'm not sure what you mean by "criterion" in this context. And no, you don't need to inherit a class or rewrite anything, that's not on the engine's side, that's on your game's side.
When loading your scene, using whatever API you're using, use Unity's methods to unload the contents of DontDestroyOnLoad.
There are plenty of ways to do it, you can google it, here was the first result : https://gamedev.stackexchange.com/questions/140014/how-can-i-get-all-dontdestroyonload-gameobjects

 

Hi, I was playing with the demo scenes in the Handcrafted Art + Corgi Engine bundle and noticed that when you wall jump repeatedly you can get stuck in the ceiling for a while before gravity will eventually kick in. Is this a known bug? How do you prevent it from happening with low ceilings if we make our own levels? By the way, I'm not pressing the space bar after I reach the ceiling or anything to trigger the jetpack included in Corgi Engine.

 

@ObsidianSpire > I think that demo scene is just missing an actual collider at the top. You can look at the MinimalScene (or others) for an example of that.

 

Hi, I'm trying to make my player being able to swap to another character after talking to him, but I found I couldn't disable the character swap by setting "Ability Permitted" to false. Is there any way I can dis able a character's swap ability and re enable it when I want? Thank you.

 

@Skyfighter11208 > You can disable the CharacterSwapManager to prevent swap.

 

Thanks for answering. But what if there are three diffrerent characters, and I want only two of them to swap with each other and the person you can swap with can be changed by talking to the third person?

 

Hi, @reuno! I am trying to work with the health bar on Enemies but it is not working correctly, the bar is displayed but it does not update with the Characters current health, even in the RetroAI scene. I have tried to create my own health bar prefab by referencing the current health from the Health script on the Character but the Health script seems to not be identified as a script. How can I refence the float CurrentHealth, InitialHealth and MaximumHealth in my own script or do you have an Idea on why the health bars are not working correctly?

 

@Skyfighter11208 > I've added such a feature to the next update, drop me a line via the support form if you'd like to have it before the next update hits.
@wikio > I've never heard of health bars on enemies not working in Retro AI in a fresh install. Maybe you've made some changes to the scene, or some scripts. Try in a fresh install of v8.4, and if the issue persists, send more info about what exactly you're doing via the support form.

 

Hello my friend, I have a problem now, I want to make a tracking bullet that can track characters, I have added WeaponAim and AutoAim to the robot weapons in the Demo, but it doesn't seem to have any effect, what should I do specifically? If you need a custom script, please also give me a simple idea, thank you!

 

AutoAim and WeaponAim just point the weapon towards the target. It doesn't update the projectile's direction mid flight. For a tracking bullet you'd have to create a custom projectile class that constantly updates the projectile's direction.

 

Thanks for the valuable advice, I hope the engine can give this kind of tracking weapon demo scene later

 

I have just been writing the code for this, and I've almost finished it. I'll share it with you once I've done it - it might not be what you're looking for exactly but will probably help.

 

@apdaniel > There's an extensions repository you can contribute to if you'd like :
https://github.com/reunono/corgiengineextensions

 

I implemented a semi-automatic melee weapon and the animation played well.
However, that playback speed seemed slow, so I doubled the animation playback speed.
Then, the animation of swinging the weapon started to play twice.

Melee Wepon -> Melee Damage Area Timing -> Active Duration
I thought the above might be the cause, so I shortened it to match the animation as well.
However, the hitboxes now disappear faster, but the animation still plays twice.

I would appreciate it if you could tell me how to fix it.

Self resolved.

TimeBetweenUses
was unchecked.

I don't have a good understanding of TimeBetweenUses, but why does it behave this way if it is unchecked?

 

My apologies for repeating myself.
Self-resolved.

The parameter was not Start but Use.
This is why it was a looping process.
Setting it to start fixed it.

Sorry for the trouble.

 

Oh, I can't wait.

 

Hello,my friend, now I have a problem about charge weapon, I set the secondary weapon to charge weapon, I keep the default setting of "MinimalChargeWeapon"
But there are two problems:

1. The weapon is always charged, whether I press the attack button or not;

2. The bullets fired after charging are all in the first stage, and I have set the bullets and charging effects of different charging states

I don't know if it's my weapon stats or something else

 

@Dumpling007 > Could you explain what exactly it is you're doing, and how to reproduce your issue?

 

I went back and reenacted the bug:

Just add the "Character Handle Secondery Weapon" to the Player and add the" Charge Weapon" to the component and it will trigger the bug I described, you can try it out

 

@Dumpling007 > Again, without knowing what exactly you're doing, where, with what character, on what version, it's hard to tell what the issue may be.
These steps will work, I'd recommend trying them :
- fresh install of CE 8.5 on 2020.3.48f1
- open MinimalLevel
- edit the Rectangle prefab, add a CharacterHandleSecondaryWeapon to it, set the MinimalChargeWeapon as its InitialWeapon
- save the prefab, press play, use your mouse right click to shoot/charge the weapon, it works as designed

 

It's great that CE8.5 is available so quickly, problem solved, thank you very much

 

Hi, I've had some issues with Corgi's object poolers, when Domain Reload is disabled (in Unity's Enter Play Mode options).

MMObjectPooler.cs has a "static Instance" that isn't properly cleaned up when the game is restarted while Domain Reload is disabled.
Because of this, sometimes the Instance wasn't being correctly initialized on Awake(), and this caused some null/wrong reference exceptions later, on my pooled objects.

Adding the following code in MMObjectPooler.cs makes it more compatible with disabled Domain Reload.
I added this code above the Awake() method.

Code (CSharp):

1. [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.SubsystemRegistration)]
2. protected static void InitializeStatics()
3. {
4.     Instance = null;
5. }

 

Another issue I noticed:
It seems the CharacterWallClinging (wall slide) movement is currently frame rate-dependent.

In my game, when the frame rate is high, the character wall slides with a normal speed.
But if the frame rate drops considerably, then the character starts sliding down much faster.

I'm using Corgi v8.5, Unity 2022.3.5f1.

 

@andreiagmu > Thank you for spotting these! I'll fix the domain reload issue. And there does indeed seem to be something off with the clinging vs framerate, I'll fix this for the next release. If you find more bugs, or if you'd like the fix for that one before the next update drops, don't hesitate to use the form at https://corgi-engine.moremountains.com/corgi-engine-contact.

 

Great, thank you very much for the support!

I also want to share an extension class I made for CharacterPersistence.cs, that moves the character to a custom scene instead of moving it to DontDestroyOnLoad.
I generally avoid moving stuff to DontDestroyOnLoad due to some issues with it, so I have a custom additively loaded scene in my game, for persistent objects.

In the component's inspector, you just need to set the correct scene name to the persistentSceneName field, then the character gets moved to that scene.

Code (CSharp):

1. using MoreMountains.Tools;
2. using UnityEngine;
3. using UnityEngine.SceneManagement;
4.  
5. namespace MoreMountains.CorgiEngine.Custom
6. {
7.     [MMHiddenProperties("AbilityStartFeedbacks", "AbilityStopFeedbacks")]
8.     [AddComponentMenu("Corgi Engine/Character/Abilities/Character Persistence_CustomScene")]
9.     public class CharacterPersistence_CustomScene : CharacterPersistence
10.     {
11.         public string persistentSceneName;
12.  
13.         protected override void Initialization()
14.         {
15.             base.Initialization();
16.  
17.             if (AbilityAuthorized)
18.             {
19.                 SceneManager.MoveGameObjectToScene(gameObject, SceneManager.GetSceneByName(persistentSceneName));
20.             }
21.         }
22.     }
23. }
24.
