[Game] Minetest Defense

[Kalabasa]

Warning: This is a WIP so expect unbalanced and broken gameplay! Don't expect a complete and working game.

Description of what the game would be when completed:
This is a coop (or singleplayer) game of building, surivival, and defense. Players must build and defend a fortress against waves of monsters to survive. Monsters come every night, with increasing difficulty per night. Nowhere is safe. Not even in your own fortress. During the day, monsters will disintegrate while players repair the fort and gather materials.

Spoiler

• monkey (basic monster) [done]
• minotaur (breaks walls) [done]
• bat (flying) [done]
• puffer (flying, spits caustic goo) [done]
• an underground monster to discourage hiding in a hole
• (need to think of more)

logic

• give initial items (like building materials, or weapons) [done]
• adaptive dynamic spawning [done]
• kill monsters when morning comes [done]
• increase difficulty per night [wip]
• Make a respawn timer/Fix respawning
• Restart the game to day 1 if all players died

• make time of day faster [done]
• music [done]
• sound effects
• particles
• improve multiplayer play

During the day players build their fortress.


Night is approaching! Get ready to defend. Monsters come at night.


Monsters! (The wall isn't high enough, apparently)

OOOOOHHHHH!!!!!! I LIKE! Great idea, I cannot wait to play this!

Quick notes:

I did get this error:

Code: Select all

Spawn 5 defense:unggoy at (-106.04752016478,7,-128.66747094955)

Spawn 1 defense:unggoy at (-138.02163507935,7,-151.45400918979)
Could not open file of texture: fortress_unggoy.png

And could not find fortress in any of the Lua's I am not sure how this came up, only when a mob would spawn.

I like it! I couldn't build a home quick enough and died, and once I died it was all over for me. LOL. You made a very difficult game here, great job!

Things I would change:

*Give initial items should include 200 cobble, just to get started. A few torches and a stone pick.
*Add sounds to monster when attacking? Maybe, maybe not, the sound might become repetitive.
*Increase the light effect to de-spawning the monster, they were sticking around a bit during the morning and day and I wasn't able to free myself.


Keep up the good work!!

[Kalabasa]

Thanks for the reports! I'll add that to the todo list.

fortress was the former name of this mod. I don't know why it still looks for those files.

It's a bit too hard at the moment. Currently it spawns whole horde of monkeys.

Edit:
Right now I'm focusing on adding content. Tweaks come later.

Edit:
Apparently Minetest still searches for the textures saved in the b3d (model file), even though it replaces the texture. The b3d still wants the old fortress texture. I updated the b3d file now.

[Enke]

Looks really neat! I think I'll check this out tomorrow, if I get the chance.

EDIT: Well, I couldn't find too many problems here, other than the fact that monsters not only spawned in the day time, but also spawned immediately. Other than that, I had a blast with this game!

Same here...but it didnt matter, its just too much fun!
Those monkeys are relentless!!

Its not bad as just a mod either :)
I added it to a really minimal subgame and it still works great

This is the first game I have played where mobs dont completely bog me down,
I mean virtually no lag whatsoever.

Please Keep up the good work

Added a new monster "Sarangay" (or minotaur)

It can break your walls by charging.

Added a new monster "Paniki" (or bat), which is still a wip. They're flying squares at the moment.

It's good to read that mobs weren't eating resources (at least, in your case). There's about 50-70 mobs at a time. (I should control/reduce that since Minetest can't handle more than 49 mobs in one map chunk)

[Minetestforfun]

Thank you for your work and your subgame !

Im very interresting about your work on mobs, the "Sarangay" (or minotaur) is awesome ! (maybe i will add it in my server)

[Kalabasa]

I don't know if it's compatible with other mods.

1. I did not use any of the existing mob libraries/frameworks.
2. It breaks blocks! You may not want your server griefed by some mob.
3. It does not spawn automatically/independently. In this subgame, mobs are spawned by the Director. You should write your own spawning procedure (like ABMs) if you're going to take some mobs.

[Minetestforfun]

1) It's adaptable
2) It's a good feature ! =) (but tweaked for choose the destructible blocks)
3) The API can add spawn ABM

I repeat, your ideas and work are very interresting :)

[maikerumine]

Real quick, I downloaded the latest but the throwing mod folder is empty.

[Kalabasa]

Thanks for the feedback!

Real quick, I downloaded the latest but the throwing mod folder is empty.

The throwing mod is a git submodule in the repository. Submodules aren't downloaded by default in git, iirc. You should do a git submodule update.

If you used the ZIP option from GitHub... I don't know.

For now, remove the throwing folder. It isn't being used currently anyway (But I plan to include it sometime).

QUICK REVIEW TIME!!

I spent some time at lunch on this game and found it to be incredible. Typically with mobs either elevation or a secure box of cobble does the trick, not this time!

Day one:

Grab some dirt, saplings, and wood. Make a 1x1 tower 18 nodes tall and extend a platform out in a square. Plant a tree and craft a ladder to get down after the monsters leave. First wave, they came in a swarm, I was tense, continued to craft some things... I started seeing red! I was getting attacked?! They were climbing on each others backs to reach the bottom of the platform! WTF!!?? I died, then was lost in the dark only to die a few times over again.

Day two:

Make a underground fort, that will stop them. Made a fort under an island with water access and blocked all but one 1x1 hole to see the mobs. Bad idea, the pressure and amount of monsters eventually popped one through the hole and he got in, I killed him with the sword provided, THANK YOU, and blocked the hole again.

Skip time to a large number, edited the environment parameter to see full force...

Another bad Idea.

This time I had the minotaur bust through and totally let dozens into the fort, I was done!!

So I decided to noclip and fly up through the ground to see the masses...

BATS!! I was getting attacked in the air too!!!


In summary, it was such a white knuckling experience, like pure terror. Knowing you were never going to escape or survive! In hind sight I would gather much more resources and build higher and enclose the fort. I'd like to see a minotaur climb 50 nodes!

Good Game, you did very well with this idea, keep it up!!

[Kalabasa]

Implemented two new features:

Music
This is intended to bring suspense to situations, and generally give some life to the game. Incidental music will play at certain events in the game.

The music depends on the tension of the player. I haven't tested this on a network, so the timing may be bad on networks. I haven't tested this on multiplayer too. Currently the same music plays for every player, which is not good, because each player has different tension levels.

Pathfinding
(Some selected) Mobs now find a path to you, instead of running into a wall between you. This may add some CPU usage a bit, especially when you are constantly moving or in an open space. I haven't tested this on multiplayer, but I think processing will increase if players are spread apart. If they are huddled in some place, CPU usage will be as if there is only one player.


Looks like I'm focusing on singleplayer experience for now. Coop play may be unbalanced (too easy), broken (laggggg), or totally unsupported (BSOD (just kidding, just crash)).

[Minetestforfun]

Your work on mobs are very impressive, i've never see pathfinding on others mobs mod !
It's a very great improve :)

(maybe you can improve the actual mobs API if you work with other mods mobs creator)

+1
I second this note. Your mobs are very ruthless, the best I have seen yet. keep up the good work!!!

We had a blast with your game tonight. I started the server with your game instead of our usual map. I didn't tell the wife and kids and insisted we log in at the same moment.
At first they were stunned to see some items in their inventories. I told them we need to work together to build a shelter NOW. So we did. it was a simple cobble box with two windows and a door.
Then dark hit and the kids saw monkey hell running up the mountain at top speed. We were hit a ton of times before we got inside and the door shut.
Noticed monkey heads coming through the door like ghosts, but they didn't seem to come in. Then we noticed green slime covering a window and then the roof started coming apart.
There were five of us trapped inside this cobble box as bats monkey's and God knows what else flooded the inside. All of us complaining how our screens were solid red as we died one by one.
Awesome!
Daylight hit and it was over. So we dug into a mountain as fast as possible and survived the next night huddling together like cowards. Not being able to see what was going on outside was torture as we could hear all kinds of action out there and our laptops were playing eerie music. Surely death was upon us?
We played four hours straight having a blast the whole time.
Our server is a old Core Dual Quad with 4 gigs ram. It is on our LAN. We honestly didn't notice any lag ever running the subgame with no extra mods. That is saying a lot as two of the five laptops were netbooks.
Your models look great! Or what I could see of them. Mostly monkeys and bats. All the mobs were interesting and just crazy! It's hard to kill them as they are moving around so much. But so fun!
Thanks for your work so far, really looking forward to seeing how this one turns out.

[Wayward_One]

Awesome game, I haven't played singleplayer this much since before joining my first server! :D

[Mg]

Could you please add your .blend files to the git repository?
It would be great if people need to modify the objects. :)

[Mg]

Oups double post, thanks to my computer disconnected half the way (any moderator feel free to remove this one).
So, your game is great, and path finding for mobs is a very helpful feature in AI designs.

[Kalabasa]

Hi

I wasn't able to update this game because of schoolwork (I'm doing my undergraduate thesis right now).

I uploaded the blend files to the repository.

Also, I (accidentally) added the still-incomplete spider enemy "Aranay". It may be buggy.

i've been running a stripped down version of just the bats on my server but been having server crash problems.
i prefer the more natural way your bats fly and attack vs the simple mobs api but i have also converted your ape and minotaur models to run on simple mobs api to better control spawn location and population. awesome models love their animation!

i compile and run dev version of server so that maybe that is issue i'm also running your newest code. i have also added drop on death to the mob.lua that seems to work fine and have also omitted the code line 162
minetest.chat_send_all("dir:" .. minetest.pos_to_string(direction))

here is crash info

bravo on your work, again i love the way the bats fly and hunt. a feature i'd like to see is bat avoiding water or at least taking water damage.

lastly can you explain the code used to spawn and which variables can be modified to reduce number of mobs
defense.director = {}
local director = defense.director
director.call_interval = 1.0
director.intensity_decay = 0.93
director.max_entities = 50
director.spawn_list = {
{
description = "Unggoy group",
name = "defense:unggoy",
intensity_min = 0.0,
intensity_max = 0.6,
group_min = 1,
group_max = 4,
probability = 0.4,
day_start = 0,
spawn_time = 14.0,
spawn_location = "ground",
},

This sounds like a mod with full potential. Maybe I should try it out? Only one problem though. I don't know how to download mods. Just reading this topic gets me pumped up. I would like to try out this mod. How do I download mods?

[twoelk]

This is a subgame which among other things includes a collection of mods. It is more than simply a mod.
Simply download the zip-archive linked in the first post and unpack it on your system. Delete the added suffix -"master" from the folder name and drop the folder into the games folder in your Minetest installation. On the next start there should be a new icon on the bottom of the main menu that loads a list of worlds that use that subgame. You may have to create a new world - and the fun can start.

There are threads on the forum about installing subgames and you may want to also visit the Minetest Wiki to learn more about subgames.
