Update #1

Still haven't decided on how to simulate the underwater animal movements  - I'd like them to cruise lazily at a certain depth, then occasionally dash towards something (maybe something appetizing ?) and change direction and depth at random intervals - not too erratic though.  I'll need to give it a bit more thought but will leave this for later . 

Also, I've struggled a lot with handling collisions in the way I want.  The sub now collides and  "loses" player control for 3/4 of a second as it bounces of the obstacle and takes damage. I'd like the creature to respond by swimming away when this happens too. My understanding  of Godot's KinematicBody2D collision model is that after it moves_and_collides() one must handle both the response of the moving agent and the body that was collided into - It seems to me that this code has to be done twice  in mirrored fashion (for both sub and creature move_and_collide())

Another frustrating thing I've struggled with is not being able to flip the collision shapes whenI flip the sprites on my game objects .  Tried using :

apply_scale(Vector2(-1, 1)) 

and 

set_scale(Vector2(-1, 1)) 

on the collisionshape2D for an horizontal flip without success (strange behaviours encountered). If somebody knows how to do this correctlky, will be much appreciated.

Also learned a lot about colision masks (applied them) and also tring to put signals into my objects to reduce coupling.

so far today i've got:

1. smoother sub movement
2. area2d to smulate the "camera ready" in proximity of a creature
3. crude creatures movement
4. basic HUD with damage indicator
5. player damage logic
6. better sub collisions handling
7. physics collision masks

Here you can see I've used Godot's colliision shapes debug views - specially the "camera ready" around the sub.

I'm exhausetd! tomorrow will keep going. Quite amazed at the amount of creativity I've seen by other game devs so far.

Until next time!

Hi J, thank for your helpful reply - these are the answers

1. Will take your advice for Trello - definitely a better way to manage
2. The engine I'm using is Godot 3.x   

Thanks again!

Hey Nathan, cool game idea! what are your thoughts about using Trello? have you tried it or something else?

Hi fellow gamedevs! this is my first game jam ever so please be patient.

Yesterday did a bit of brainstorming with my son as to find a nice concept for a game that I could build in time for the Jam.  Wanted to use the theme of Water for simplicity and because in itself it's always fascinating anyway. He's an incredible ally to have because he's creative and his mind goes into places where my years of office work have forgotten about.

He wanted something as ambitious as a clone of Subnautica but i managed to convince him to hold his horses and reduce scope to something achievable in two weeks . So we (well, he mostly) came up with this idea:

"Harold Wickers and Edward Johan are two researchers hired by a company called Underwater Life to document endangered  underwater species. They have been provided in good faith with a donation of the research submarine Deep and suitable contracts to retrieve footage from marine species at three levels in the ocean:  the surface level, the twilight zone and the sea floor. However, at the beginning Deep is only capable of navigating the surface level - further adjustments and upgrades will be needed to explore the other two levels. Deep is launched into the sea by a scientific vessel, the HMS Abyss Hunter.

As Deep is a research submarine it is only fitted with  a HD video camera and an advanced species detection system to help it find the creatures specified in the contracts. Once in close proximity with a species the video camera will be activated and the submarine needs to remain close to the animal for the time required to capture suitable footage.

By fulfilling a contract and once returned to the ship, the explorers can receive credits to refuel, fix and upgrade the submarine.

Obviously, marine dangers await the two explorers in their quest but there's also something they suspect the company hasn't told them about - maybe a secret lurking in the depths of the ocean? that no one else's eyes have seen?"

As this is mostly a side project (got a family and day job to take care of) I've created a Trello board to keep track of what needs to be done . First time using it, as at work we use Jira but I think it's too much really - wanted to keep it as simple as possible:

https://trello.com/b/qT1u6d5h/my-first-game-jam-2018

The gif above shows the progress made on the first day. Managed to create some crude sprites (I'm in serious need of an artist - completely lacking those skills) and made the submarine move a bit fluidly using lerp() to a fixed target speed on a kinematic body2d. Also, using an inverse gravity force as to provide a sensation of positive buoyancy - haven't yet decided if this is best or if maybe let the sub oscillate between two fixed points of the y axis.

I guess the marine species should swim in kind of a sinusoidal cadence, randomly raising or lowering their cruising depth - any suggestions?

Don't know most of this yet - I'm learning these techniques as I build.

For marine species detection I was reading a bit about ray-casting. My idea is that when the submarine faces a certain direction it indicates to the player (maybe through a blinking light) that a species is in a given direction and out of view. Blinking can go faster as they get closer (maybe an Area2D is the best for this?).

Once the sub is close to the marine animal - I'm thinking inside another Area2D surrounding the target - the camera recording action is active and user has to press a button. Sub has to remain close for a limited time until footage is complete.

This is enough posting for now. I'll be grateful for feedback when I get back to work tonight and hopefully will have some comments .

Semper Fi Game Makers!

Hey, who can resist the appeal of trains and logistics?

First of all, thanks to the community for the opportunity given to first time game devs. It certainly can be intimidating!

1. Hi there! What's your name? Want to introduce yourself?

I'm reyabreu, can call me just Rey.  A seasoned Java enterprise dev for a living (I know, boring) but an avid gamer, reader and movie watcher  - maybe a bit older that your typical audience but still young at heart. I've recently started on my journey of learning the essentials of gamedev in the hopes of it becomimg an established hobby where I can do something much more creative and meet likewise minded people. English is a second language so please be forgiving of any errors...

2. Did you participate in the last jam we held? If so, what do you plan on doing better this time? If not, what's your reason for joining?

• Never been in a Game Jam before. Heck I've never programmed in a competition before
• I intend to do my best to actually finishing my own game. I'm really bad at art, sound or design though....
• I want to learn the essential skills to produce a game that someone will actually enjoy playing

3. What games are your favorites? Did any of them inspire you, or made you want to make your own?

So many games I've played over the years... Let's see.  I tend to enjoy more linear narratives instead of open world:

• Limbo, Inside, Shadow of the Colossus, Katamari Damacy, ABZU, SuperHot, Alien: Isolation, Papers Please, God Of War, Ryse: Son Of Rome 
• Starcraft, XCom, Civilization, Total War and Tropico Series
• Mad Max, Skyrim, Just Cause 3, Tomb Raider, Last of Us, Sniper Elite 3, Mirror's Edge, Subnautica
• Hearthstone, Poly Bridge,  Turmoil, Swat 4, Transport Tycoon,  SpaceChem, Psychonauts, Machinarium, Minecraft

Board games: 7 Wonders, Setllers of Catan, Agricola, Age of The Dragon, Ticket To Ride

I'd love to make a game with a compelling story such as Papers Please - which I hold as a masterpiece. It made me start looking into gamedev with more conviction.

4. Do you have experience with game development? What did you do/with what engine?

Nope, no "formal" experience with gamedev. I started programming many years ago, but focused on more "serious" problems for commercial or academic applications. After I saw the success of Minecraft, I started looking into gamedev with Java and gamemaker studio first, but dropped them after I realized the huge amount of effort it involved to do something reasonably acceptable.  I took it again recently after doing some tutorials on Unity and Godot on Udemy (specially fond of Godot!)

5. Tell us about something you're passionate about!

I think games are another type of media vehicle that hasn't been fully developed yet in it's potential for telling compelling stories and even change our minds - like books or movies. I think that unfortunately most game dev is still heavily technical. Creative and writer types face a bit of a steep learning curve before being able to produce valuable content. I personally don't care much about the next fps or "retro" platformer (which have been done to saturation) but for creative ways of visually telling stories or innovative use of inmersion (like Superhot).

6. What are your goals for this game jam?

Finally make a game from start to finish which  I am not too ashamed to put on display!

7. Any advice to new jammers (if you're a veteran)?

None. I'm very willing to take advice though!

8. If you're a returning jammer, what can the admins do to improve your jam experience?

Hope to answer this later
