Dev Log #03 Combat Pt 2

In many action games, enemies have an invisible variable that slowly builds up whenever they take damage. Once such a variable meets a certain threshold, enemies get interrupted. People call it stagger. In Dark Souls, it's akin to poise. In fighting games, this is something like the super armor. In my game, Grid Lost, this variable is the shield.

Shield

Shield works similarly to shield in Slay the Spire; it prevents incoming damage to HP. Additionally, in my game, the shield protects Daemons (both players' and enemies') from interruption. However, shields do not negate status effects. One thing that works differently from Slay the Spire is status effects such as overheat and parasites (think of them as burn and poison) do not damage shields; these effects do true damage, which ignores shields and directly damages HP.

So why create an additional damage type called true damage?

Uh... my preference? Ok, it's a little bit more complicated, but mostly my preference. There is a simple trick to empower players: LARGE NUMBERS!! Many cards can do hundreds of damage with the right amount of damage buff. However, this creates a problem since large numbers are harder to compute. 

If you're good at math, this is a non-issue. But even if you're good at math, doing that kind of calculation will become annoying and bothersome after an hour. I keep the shield value as small as possible and create a separate stat called shield damage, which is smaller than the regular damage. I could slap the shield damage variable onto every effect, but I want more varieties, hence, the introduction of true damage.

Status effects and passive effects 

In the game, there are two types of effects on a card: status effects and passive effects. Status effects work just like any other RPGs; they do DOT or increase/decrease characters' stats. Passive effects passively boost a card's potency or cause combo damage under certain conditions. 

For example, burst causes an explosion that damages adjacent Daemons if the attacked target has overload status effect. Burst does 2 shield damage to the explosion origin and its adjacent Daemons; this allows fast cards that do low shield damage into an absolute monstrous shield wrecker.

Some status effects do true damage, while others don't. Passive effects usually do non-true damage (for now, I've not added a true-damage passive effect. Maybe I will, maybe I won't). True damage sounds too good to be true, right? It does direct damage without concerning shields. 

BUUUUUUUUUUUUT, there is a drawback: true damage cannot interrupt. 

The intention of true damage is just a way to pressure your enemies when you cannot break their shield. Enemies are going to get stronger after each level, and players need tools to chip away at enemies' health. But remember, your foes can do the same things to you.

Now let's get back to the shield. How do players and enemies regenerate shields? Through cards?

NO. Yet another design that is different from traditional deck-builders. Grid Lost doesn't have a separate independent turn for players and enemies. If I had to play a card just to generate my shields, I would be wasting my turns desperately repairing my shields while letting enemies rain down hellfire upon me. HECK NO. On top of that, if I didn't have a card that gives shields, I would be at a severe disadvantage, especially in early games.

The solution to the problem is inspired by Chained Echoes. In Chained Echoes, there is an overdrive bar that increases/decreases depending on the action you take. While yellow, you get no beneficial effects. While green, you do more damage,  take less damage, and your skill costs less resource. While red, you take more damage.

In Grid Lost, this mechanic is called RAM level. Every card that you use has a RAM value. At RAM level 1 (green), you gain 5 shields every turn and you take 50% less damage. At RAM level 2 (yellow), you gain 2 shields every turn. At RAM level 3(red), you gain no shield and take 30% more damage, but you do 100% more damage. Make sure you time your actions correctly. Taking advantage of the benefits of each RAM level is the key to success.

Be careful! The worst case scenario is taking damage when both you and your enemy is at level 3, it's pretty easy to hit over 400 damage in this scenario. Most Daemons only have about 1000 health, THAT'S 40% OF HEALTH GOING BYEBYE YO! 

Dev Log #02 Combat Pt 1

At the beginning of this project back in 2022, I had a very different idea for this project. It was supposed to be a memory-matching game with some rouge-like elements. Shortly after the start of the project, I temporarily worked at a game studio for 2 months. The studio was making a beat-em-up game, which got me thinking: "Maybe I should make a card game with mechanics inspired by action games." I didn't quite figure out how to mesh that idea with my memory-matching game, and thus, I completely scratched the memory-matching concept and redesigned the whole combat system.

Question 1: How the hell can I implement "frame data" from fighting games in a turn-based game?

Well, I can't. But, there is an alternative. To discuss the alternative, first, we need to understand what "frame data" does. In a fighting game, an attack consists of startup frames,  active frames, and recovery frames. 

Img by Dash Fight, https://dashfight.com/news/understanding-frame-data-in-super-smash-bros-ultimate-161

What we need to focus on here are the startup frames and recovery frames.  Startup frames determine how long it takes for your attack to become active.  Recovery frames show how long it takes for the character to return from an attack pose to an idle pose. The character cannot do anything until it returns to the idle pose. Hitting an enemy causes the enemy to start the on-hit animation, and it would take x amount of frames for the enemy to return to its idle state.

We need a system that tells the player who will act first and also a way to confirm whether the next attack will trigger earlier before the enemy's action. We have seen "this system" in turn-based RPGs, like Final Fantasy. Players can apply a debuff to slow down the enemy, which is like to confirm your next action will start before your enemy recovers. In other games, players' attacks can even delay the enemy's turn.

My solution is slightly different. I call it the Initiative Priority System. The side with higher initiative goes first.

          Initiative = card speed + speed mod

The card's speed value is like active frames; it shows how fast your action is. In my earliest prototype, a card had an enemy-delay mod and a self-delay mod, which simulated the enemy's on-hit recovery and the player's attack recovery. However, there was so much information on a card already, and having these two would only complicate the game further. Therefore, I combined these two values into a single value that I called speed mod. 

Playing a card adds speed mod.  Speed mod influences your initiative on the following turn. Note that the value does not stack (some cards bypass this rule with special passive effects). If you take a hit, then your speed mod decreases to 0.

The pointer above shows my initiative. The one below shows the enemy's initiative. In the above case, I have a +2 speed mod from my last attack. The last attack was a successful hit, which reduced the enemy's speed mod to 0. In a way, one can say that I have a +2 frame advantage. Even though the default speed of my enemy's action is faster than mine by 1, because of the speed mod advantage, this turn I can act first.

An important aspect of combat is to manage your speed mod so you can act first and interrupt your enemy's action. If the enemy gets interrupted, it loses that action and moves on to the next. If done correctly, you can constantly interrupt your foe and completely deny its turns!

However, there is a problem... Players can see the enemy's intent. If so, wouldn't it be too easy for players to constantly interrupt the enemy's action and never worry about getting hit? Well, that's where the shield mechanics come in~ Since this section is already getting too long, I will talk about shield mechanics in the next post. Stay tuned!

So simple yet so addicting. I thought I got the perfect run, nearly endless supply of mana, then got cocky and overlooked how much of a threat taunt enemies are...

Dev Log #01

Hello~ This is the dev log for my solo indie game Grid Lost. I've been working on the game for 2 years and I think it's about time to let my "baby" see the light of the day. I'll keep my dev log short, cause 'too long and no one wants to read'. The 1st dev log will briefly cover the general setting (story, genre, and combat).

https://kakuseika.itch.io/gridlost

Notice: A new build is uploaded as a Google Drive link. Currently, there is a limit to the file size on itch.io and I'm working on getting it increased.

Story

The story takes place five years after the end of the Cold War. A fictional island nation the United Vaniber (UV), developed the most advanced information technology (the Grid network) and artificial intelligence (Daemons) that the world had ever seen. With these creations, the UV quickly rose through the ranks to become the most technologically advanced nation in the world. Because the UV refused to share its creation, a "hunt" to steal the Grid technology began. You play as an anonymous contractor working directly under the United Vaniber Intelligence. Your mission is to eliminate invaders and prevent the technology from leaking to foreign nations. 

The game takes place entirely inside the Grid network. In the digital world, anything is possible, like in Minecraft;  there is a lot of liberty to aesthetics.  For the 1st act, I chose a cyberpunk environment, which fits the sci-fi theme of the game. 

Genre

The genre is rouge-like deck-builder, similar to Slay The Spire. Players will start each run fresh and slowly build up their deck. The difference is that instead of choosing a playable character, you will choose up to 3 different Daemons. Each Daemon comes with its own set of card pools and relic pools. Abusing the synergies of cards and relics is the key to conquering your foes. To get Daemons, you need to pass the negotiation.

Unlike Shin Megami Tensei, which requires players to give the correct response (usually fixed) to the Demon's question or request; in Grid Lost, Daemon negotiation is a slightly more complicated and randomized mini-game. Due to the length of this dev log, I'll write about the negotiation mini-game in a separate dev log in the future.

To separate itself further from the pack, Grid Lost uses a unique combat system that I've not encountered in any other games in the same genre.

Combat

Instead of having separate turns for the enemy and player, both sides will act at the same turn. So how do I know who will go first? The initiative decides the order of actions. If yours is higher, you go first, and vice versa.

What'd happen if both are equal? A clash will happen where both sides are competing to gain the upper hand. 

For more information about the combat system, please stay tuned for the next dev log! Alternatively, you can try out the demo and see for yourself~

If there is any feedback, feel free to leave a comment and help me to make the gameplay better!

I really like the game idea, art style, and music. While playing it, I'm constantly thinking about card games. It might be interesting to have some card management (or dice management in this case) in the game. 

Thank you. I agree the movement is an issue.  Unfortunately, didn't come up a better solution during the Jam

One of the most unique ideas I've seen. Playing as a frog is brilliant. 

One of the most unique ideas I've seen. Playing as a frog is brilliant. 

Ye. I wasn't able to solve the gimbal lock and some rotation problem in UE4, so I broke up the movement and rotation into separate game mechanics

The art is amazing. Great tutorial levels to teach all the important mechanics. As for game levels, I wish there were more alternative routes,  so I wouldn't have to wait for the RNG to be in my favor. It's entertaining to see AI getting trapped or even sunk, but getting trapped due to poor RNG can be a little frustrating. 

Inkless is a 3D puzzle game in a Sci-Fi world. You play as a dice, an inkless dice. Collect ink scattered around the map to progress. To collect ink, make sure the correct side is touching the ink. Use the mechanisms in the level to change your movement direction and orientation. Explore an abandoned facility. And remember: "Don't be INKLESS."

Link: https://steadjojo.itch.io/inkless

The simplistic art style, love it! Nice choice of music, kinda reminds me of a Lego Build's journey. But the control feels confusing sometimes (partially due to the isometric camera ).

Interesting but maybe too ambitious for a 48-hr game. I'm not sure whether I'm progressing because I am regularly teleported to different areas.  There should be some kind of reference to prevent players from getting lost. Traps should look more deadly! I didn't know it was a spike until I walked into one.  And the background, middle ground, and foreground should be more distinguishable. 

Cool and very trippy~~~~. The crosshair needs more contrast and BIGGER!!!!!!!

Got it, my misunderstanding of the rule. 

Cool art. The different dice ability is interesting. However, there are a few issues:

1. Damage adjustment. Red dice, the first ability, should do a bit more damage. Instead of a 6-hit kill, I suggest buffing it to a 2-hit kill or at least a 3-hit kill. Currently, enemies take too much damage to die, which negatively affects the pacing for a beginner level. Should you decide to buff the red dice, you should also increase the yellow dice damage to showcase its power. 
2. RNG, green dice & yellow dice. I like the idea of teleporting dice and an explosion dice that turns you into a rocket man. However, movement options should be persistent, especially when I need to get over a large gap.
3. Tutorial. For example, (for blue dice) shorten the spike distance. I can drop one ice, jump on it, and get to the next platform. Also, the duration of the ice can be longer. Ideally, there needs to be a visual cue that tells players when the ice will melt and disappear so players can react. But it's a 48-hr marathon, who has that kind of time, right. So the easiest way is to prolong the duration of the ice cube.

Interesting concept. There is a bug with the square pattern. 

3 6 

5 6

1 2

so 3 + 6 + 6 + 5 = 20, but the game doesn't count that as the correct combination. Do "1" and "2" interfere with the final result?

Wow, great ideas and mechanics design. I wish that I could hold onto a piece of tile, similar to some Tetris games.

Create all the art within 48 hrs? Respect. However, I think the city-building game that you are aiming for might be too big for a 48-hr jam. Need more rules. Currently, I can place any tiles beside any other tiles without restrictions and limitations. There is a lot of potential, and I'm interested in what this game will become in the future.

Wow! Really interesting concept! I like the idea that the top side of the dice determines what weapon I can use. The weapon recoil is fun. Shooting a laser and seeing myself get yeeted to the other side never gets old. Melee enemies are the biggest challenge. I often find myself getting cornered by them. They add a new layer of decision-making since they impose a larger threat to players. But getting trapped without a way to fight back can be frustrating.

Maybe 1 or 2 seconds of I-frame after getting hit (changing collision profile to something that ignores enemy collision)? For a physics-based game, this is probably not the best idea. And it will be weird seeing players passing through enemies. Another idea is to change melee enemies to short-ranged ranged enemies (like a shotgunner). Poker cards have a unique bending melee attack. Maybe instead of melee, it generates a gust of wind at its "stomach" that propel players? Adding a longer cooldown to melee attacks may also help. While in cd, the card will stand still instead of moving toward the player.

Thank you for your feedback. Because I had played the game so many times, I completely overlooked the potential of people getting lost because of the control change. Adding an arrow is an excellent suggestion! The implementation of the "Hiding Wall" was kinda rushed. The camera is a big challenge that requires more time to tune. In short term, I think I'll change the "hidden" material and increase the line trace range to cover more area.
