Games WIP Small Works Game / Programming Thread

Hello, I have made a video below of my current WIP. I have recently added art and textures so it's not this bland. Just showing some of the features of my game. (Video quality is not that great, if anyone has tips for achieving better video recordings, please PM me.)
I'll update my WIP thread this afternoon.

 

Working on adding Jitter Physics to Unity as an alternative to Unity's built in physics engine.



Here you can see a simple scene I created using cubes. The walls and floor are all static, and the cube in the middle bounces off the walls and stuff. You also see the debug drawer mode enabled in the editor view - all meshes and stuff are highlighted with red lines, which is quite useful for making sure Jitter is synced up with Unity.

Advantages of using Jitter over Unity's physics:
- More efficient and faster - you can use multi-threading to make the most of multi-core platforms
- Control over everything - Jitter is open source, so you can code your own extensions to it
- Rewind and replay techniques for server authoritative networking are viable (this is the main reason I'm making this)

 

After 1.5 days I've successfully ported a Chip-8 emulator to Unity It is slow, but I think that is due to my renderer using set pixel... Not sure how I can fix that though... anyway later today I will hopefully release a version with input and physical cartridges that can be put into a socket on an emulator... it gone be awsome!... Oh, and it will be open source once I'm done with my test build

 

Asvarduil:

Can you describe exactly what the behaviour you want is?

One way is to not disable the x-axis movement, but add an upward force for the jump, which means the character can jump in place, move forward, backwards or even change direction mid-jump. Some people find this unrealistic, as you are really flying father than jumping. Others have it that a single jump has one characteristic (short jump) and pressing the jump button twice makes the character jump twice as far/high.

What you do you want to see as your final behaviour?

 

The behavior I am going for:

-Player presses the Jump button to perform a jump.
-The height of the jump corresponds to how long the jump button is held.
-When the jump button is released, the player will begin to fall.
-At the apex of the jump, player input to the Jump button will be ignored.

 

Code (csharp):

1.  
2. if (Input.GetButtonDown("Jump")  !falling) {
3.      // Transform the y position here, but still taking into account the player's x and z positions
4.      // if those were manipulated elsewhere in code.
5.      someGameObject.transform.position = new Vector3(someGameObject.transform.position.x,
6.                                                                                  jumpOffest,
7.                                                                                  someGameObject.transform.position.z);
8.  
9.      // If the player reached the jump apex within this frame, next fram they should begin falling.
10.      if (someGameObject.transform.position.y >= jumpApex)
11.           falling = true;
12. } else if (Input.GetButtonUp("Jump")  !falling { // If the player has let go of the jump button, they should begin falling.
13.           falling = true;
14. }
15.  
16. if (falling) {
17.      // If you're not using gravity, then put some falling code here. Do not set falling
18.      // back to false until player is grounded.
19. }
20.  
21.  

So this could probably be prettier, but I gave it a quick shot. But, is this kind of what you wanted?

 

Pretty much. When I get home, I'll have a go at it with that logic.

By the by - thanks for showing me Input.GetButtonDown/GetButtonUp. I was checking the Input.GetAxis method in my code, but down/up will make my controls more crisp...

EDIT: Uploaded a new webplayer. The jumping feels a bit off to me somehow, still, even after revising both the player input and physics with a version of the code above, and changing from using FixedUpdate to Update.

Pretty much, my jump code looks like this now:

PlayerControl.cs:

Code (csharp):

1.     private void JumpControl(ref string animation)
2.     {
3.         if(Input.GetButtonDown("Jump")
4.             _isFalling == false
5.             _movement.isGrounded)
6.         {
7.             _movement.PartialJump();
8.         }
9.        
10.         if(! _movement.isGrounded)
11.         {
12.             animation = _facingRight ? jumpRight : jumpLeft;
13.             _isIdle = false;
14.         }
15.        
16.         if(_movement.AtJumpApex)
17.             _isFalling = true;
18.        
19.         if(! _isFalling  Input.GetButtonUp("Jump"))
20.         {
21.             _movement.HaltJump();
22.             _isFalling = true;
23.         }
24.        
25.         if(_isFalling  _movement.isGrounded)
26.             _isFalling = false;
27.     }

SidescrollingMovement.cs:

Code (csharp):

1.     public void Update()
2.     {  
3.         isGrounded = _controller.isGrounded;
4.        
5.         if(! _controller.isGrounded)
6.         {
7.             _moveVelocity.y += Physics.gravity.y * Time.deltaTime;
8.             if(Mathf.Abs(_moveVelocity.y - 0.0f) < 0.1f)
9.             {
10.                 Debug.Log (gameObject.name + " is at the apex of a jump!");
11.                 AtJumpApex = true;
12.                 HaltJump();
13.             }
14.             else
15.             {
16.                 AtJumpApex = false;
17.             }
18.         }
19.        
20.         CollisionDirection = _controller.Move(_moveVelocity * Time.deltaTime);
21.     }
22.  
23.     public void Jump()
24.     {
25.         if(Time.time < _lastJump + jumpLockout)
26.             return;
27.        
28.         if(! _controller.isGrounded)
29.             return;
30.        
31.         _lastJump = Time.time;
32.         _moveVelocity.y = jumpForce;
33.     }
34.    
35.     public void PartialJump()
36.     {
37.         _lastJump = Time.time;
38.         _moveVelocity.y = jumpForce;
39.     }
40.    
41.     public void HaltJump()
42.     {
43.         _moveVelocity.y = 0;
44.     }

As you can see, I've added a HaltJump command in the underlying control behavior to force an arrest of y-axis momentum. The player control side was easiest (I just kept to the algorithm given by Austin K.), especially after adding an _isFalling flag to the player control code, and an AtJumpApex flag to the sidescrolling movement controller.

Looking forward to feedback, and thanks for the help so far!

 

Updated, new webplayer

 

Putting my game Minibase Wars aside to work on something smaller than doesn't require lots of level design.

Introducting

Match Cubed -
http://www.kongregate.com/games/GIB3D/match-cubed

A match 3 style game based in 3D.

 

This is my game prototype.

It's a RTS game, well actually I'm still unsure... There's two design for this. The second one is Turn Based strategy.

Anyway, instead controlling the whole thing (macro micro management stuff), you only control 4 characters. Raid the enemy base and destroy their tower.
I still considering to mix both method (RTS TBS), but still figuring out how to get the perfect match (even if that possible).

The four gray capsules are the four characters. And the green diamond is the enemy.
Since I'm not good in 3D modeling so yeah, I'm focusing on working the gameplay first.

As for the Miku Hatsune model... Seeing four capsules everydays is so depressing. So I just put her on the foreground as the eyes refreshing tool

 

Particle Fun!!!

Torus



Lorentz Strange Attractor



Cube





Inside-out cube

 

Nice oldschool-ish particle shapes! How are you animating the particles?

 

Thanks , I got way cooler effects than I had originally expected. Seeing the cube invert for the first time was .

At the moment the particles can be attached with springs to either,

A particular point.​

Their original positions.​

Nothing.​

Then a force can be added from a point.
I have a CustomParticle struct that holds a normal particle plus mass, acceleration, drag, spring position, and spring constant. I have all the CustomParticles in an array and call UpdateParticle on all of them and pass the normal particles to a unity particle emitter (or two if I have too many particles for one).

I'm planning on doing a lot more, but I am mainly working on another project I put up on this forum recently.

 

Hey Asvarduil,

I thought I posted to ask you what you thought felt off still, but I guess I didn't. So, what still feels off? I do notice that the jump just STOPS immediately at the apex. Something you can do with that is once the apex is hit, or the buttons comes up, don't immediately let the play begin falling. Find some constant that feels nice to you and decrement your up-value by that constant. So if you're moving the play up by 9.8, then every frame try removing .3 from that up value until you're adding 0, then let the player fall back down.

And you don't have to use my code if it feels wrong, of course I will not be offended. The naming convention is slightly weird too when I made the bool "notFalling" when it could also be "isJumping", but it's really all the same.

But anyways, as for the jumping feeling a bit wierd, hopefully what I've said helps a bit.

 

It helps a lot! I'm thinking tomorrow of modifying my Halt Jump method to instead halve the upward force, before application of gravity to the player; I need to do the applicable math on paper before determining a default jump decay value.

As to code differences: my code differs from what you posted somewhat because I've divided the actual interactions with the CharacterController from the interface that allows control of those interactions. Basic idea, my AI entities call the same methods the player does. Tuning on the interactions part allows me to make the AI entities behave differently from the player (for instance, Slimes can jump 1.5 tiles high, where the player can jump 2.5 tiles high.) However, I took your original code as pseudocode for the algorithm to use...so, you can still say somewhat that I'm using your code! ...Somewhat.

Anyways, all that is to say, thanks for the help, this is really helping my project.

 

You're welcome. If you need any other help, just PM me and I will try to help you.

Added a tile-select sound, the game notifies you whether you have won or lost, and tiles spawn at the top every-other turn. But even with tiles spawning less often it's still very much impossible to beat.

My first project in Unity - a Motherload clone. It's obviously WIP, but - given that I've started learning Unity (and C#) 2 weeks ago - I think it's in quite good shape already. I come from UDK environment.

 

Version 1.2 of Epic Pets is now live for Androids : http://goo.gl/4Ettc





Working on layouts some more and animation fx / sounds ! We update every week on the Google

Not to be harsh- but this shouldn't be over version 1.0 yet. There's just not enough, lots of errors, and so on. Looks great, however.

 

Been working for years building all the ground works necessary for this game. Now Its finally in full development, and I am proud of what I have accomplished so far. All of this is done in Unity free. Heres the link to the forum thread to find out more info. http://forum.unity3d.com/threads/180344-Imperium-Offical-W-I-P(Open-world-sandbox-RPG)

This is an open world sandbox first person RPG.

 

Looks pretty cool. There is a lot I could nitpick at (The landscape could definitely look better in regards to the textures and distant trees) but it is in alpha. Great job, I'm interested to see how it turns out.

 

1 week prototype of Watson, a CLI for Unity to ease your dev tasks. Focused on extensibility. Following Unity's way of extending Editor stuff. Planned to be triggered from both editor runtime.

Today i worked on a Remake of the classic Snake game !

if anyone is interested : https://dl.dropboxusercontent.com/u/44674918/Snake/WebPlayer/WebPlayer.html

 

Damn this looks really really good for a Unity project. Inspired by the Elder Scrolls games by any chance? Really gives off that kind of vibe to me.

 

Working on an Unity Profiler for Unity Free, this is how it looks currently. The best part of it, not a single line of code needs to be written to profile

 

I'm working on a new game which will have a retro pixellated graphics style, ie low-resolution. It'll be roughly around 640x360 pixels. I've built a little system to adjust the area size based on the resolution and in an effort to keep the pixels perfectly square, so depending on the resolution there may be a little more or less of the game world visible but the end-user experience is of an area roughly the same size with roughly the same size looking `pixels`, no matter what resolution you run in. I guess mainly I'm aiming for desktop and maybe iPad.

The graphics system is pretty old-school. Basically the game will comprise a whopping 2 triangles as a single quad with a texture on it. I spool an entirely new image to the texture every frame from main memory. All of the graphics will be generated and `drawn` by the cpu from script! There's a good reason for doing this that will be revealed more later, but basically it lets me do some very interesting particle effects.

The game itself will be a multi-screen environment with some kind of casual scrolling. I'm not totally settled on what kind of a game it will be yet, but I know it will have creative elements and destructive elements as well as some interesting particle interactions. It could be a platformer or maybe lean a bit more towards tower defense.. more development is needed before I can tell what turns out to be the most fun.

I can't for the life of me get a screenshot to show up, though. :-\

[edit] Jepeers I think they fixed it, yay. See those lovely low-res pixels. They now no longer look right in the actual editor because I tried to change it to use non-power-of-two textures which Unity totally messes up by upscaling to power-of-2 internally, which is a major slowdown. Gah!.. gotta change my code now to some kind of dirty-rects grid spooling thing.[/edit]

[edit2] The image appears on safari on mac but not on windows[/edit2]

 

My game Apple Jack. I'm still working on it, but basically it is a 2.5D platformer in the reigns of Super Smash Bros Brawl's adventure mode. Your main character is a "Jack", a race of people blessed with super powers. After an encounter with "Yellow Jacket", Apple Jack resolves to become the Jack-of-all-Trades (King of the Jacks) by taking on the other Jacks.

Each boss will be a "Jack", whose power will fit the overall them of the world. For instance "Jack N. DaBox" will look like a parody of Solid Snake, and use boxes to his advantage. Once the player has beaten the Jack, he will get his power.

I want to develop the game for the PC and Ouya, so please check it out in the forums at:
http://forum.unity3d.com/threads/18...-Scrolling-Platformer-for-Ouya-Android-and-PC

 

Was making some tests regarding Grid movement and also the Unity´s Pathfinding system, got some pretty awsome results, what do you think?

 

Can you apply said texture to a TV in annother game then have a game in a game?

 

Um, you could I suppose. The whole game is on a single texture so it's possible. Not what I have in mind exactly. Trying to go for a fullscreen borderless artistic sort of look.

I've been working on a Metroid-esque game recently. This evening I added security-level locked doors, and hit animations for my enemies.



here's a better view of that enemy


and a spaceship I spent a lot of time on but probably won't end up using (changed the game's plot a bit recently and sort of obviated the need for this)

 

After scrapping my last prototype for not being fun at all, I decided to create my own little version of Space Taxi.



( WebPlayer )

The basic gameplay is already in (spawning customers at random, rewarding cash based on distance, fuel, refueling, a bit of GUI) but the flight model is... well, a friend of mine described it as "it looks like it flies - a brick". Any suggestions on how to improve the flight model? I already tinkered with the rigidbody settings but I am still not entirely happy with it.

 

I am working on an ocean shader to learn some dx11-shaderprogramming:

 

Looking pretty awsome, did you used a displacement map?

 

At the moment i use one map that stores all information in it.(height differnece and x and z velocity) To make it avaiable to Unity Free i will change it to use structuredbuffers but its easier to use RenderTextures for debugging.

Next step is to calculate a bumpmap to add more detail.

 

A video of a game prototype that I've been playing with over the last two weeks during downtime at work. A first attempt at designing something using GameObject independence via an event and messaging system, and cross platform (Mobile, Desktop, Web) all using only one set of scripts per-object. The video is a bit sped up to showcase the gameplay idea, any comments on the project, especially any thoughts on polishing and releasing are greatly appreciated. Thank you in advance!

 

Hi Guys,

Here a preview for our upcoming debut game called "lockdown". The game is still under development and set for release in late August. What you think?

 

New demo reel with lots of Unity stuff in it:

 

I finally got around to fixing this little display system because I think it will be useful. The problem was that when you procedurally generate a texture from script at runtime, if you ask for a rectangular texture Unity pretends to give you one - but internally it actually stores it as a power-of-2 texture, and also I think a square one. What I was seeing was a bizarrely unalterable blurring of what should've been crisp pixel-exact `chunky pixels` with perfect edges. I couldn't figure it out because I didn't seem to be doing anything wrong. Then I learned that when you use SetPixels() and Apply() to a procedurally generated rectangular texture, Unity `internally`, behind-the-scenes, actually performs an up-scaling algorithm and stores the texture as power-of-2. It uses this internally because apparently power-of-2 textures are waaaay more optimized on graphics cards than rectangular texture access, ie it's otherwise very slow. So anyway, this optimization is internal but it has real effects when you're shooting for 100% pixel quality. Plus the up-scaling algorithm they use is apparently a bilinear filter of sorts because it blends values from multiple pixels into one. That looked awful in my case, because e.g. the white row of pixels was appearing semi-transparent overlayed on top of the adjacent rows.

So basically I had to rewrite the system because I was ideally shooting for a quad which covers the exact size of the screen, and a rectangular texture which is of exactly the right size - apparently for speed purposes to cut down on the amount of data having to be uploaded with SetPixels() and Apply(), which are themselves slow. However, upon every Apply() there is this awful overhead which dropped my framerate from ~250fps at 1280x1024, to around 35fps! Crazy. So anyway, my optimization backfired because of this internal weirdness. So now I've had to recode it to work off a fixed, square, power-of-2 texture. It means that in many cases only half of the texture is actually visible on-screen, so there's quite a bit of wastage, but it is still WAAAAAAAY faster - 250fps versus 35fps. I think in future if the wastage becomes an issue then I'll have to split the display into smaller squares, to cut the bottom off, but for now it seems fast enough. My only doubts are that it might be a bit slow on older iOs, or on Ouya. We'll see.

Next step now is to actually generate some kind of game level thing to view and scroll around.

 

Just practicing my programming skills, so I made a calculator

Got some enemy FOV working:



You can edit the viewing angle, and the amount of rays used (To change accuracy). The enemy will be able to 'See' things detected by the rays (blue lines). All in about 106 lines of code.

 

Wow those look amazing!

 

Almost finished car shaders.
Full realtime IBL (diffuse, specular, reflections), no any bake or additional lighting. Just HDR environment(single skybox).
