Defend the caves

WIP games, tools & toy projects
#1

A little prototype of a kind of roguelike defence game I’ve been working on. The idea is more or less a randomly generated cave system with a couple of points where enemies spawn. For the moment it’s set to a fixed seed, so the map won’t change, but the possibility is there. You can craft different items from what the enemies drop. The enemies spawn in a wave like fashion. The map can be altered by using the axe to mine stone.

Here’s a little gif I posted a month or something ago showing the booby trap:

Playable demo

I was rather ambitious when I initially thought of this idea, and I don’t really know where to take this prototype next. Any input would be appreciated :slight_smile:

#2

Well first you could make a pickaxe to mine the stone :point:

I think the game looks neat with the shadow mechanics. Have you implemented any dynamic elements? You said there are spawn points which are fixed? I think your next step there would be to support ‘dynamic spawns’

Crafting is a great way to go. Maybe you should focus on making a crap ton of elements and combinations to make this game into a huge farm resources to win. Build structures and stuff.

#3

I’ve got some ideas for some other traps and weapons one could craft, so that’s certainly a way to go.

#5

The uniform is in the shader by that name, but I forgot to specify the GLSL version, so it should work now.

#6

the game does not run on windows 10?

Hi

I’ve just tested, it crashes under Microsoft Windows 10 when I click on “Play” with the Nvidia driver n°353.30, I have the same stack trace than VaTTeRGeR. By the way, Simn, please put everything into the JAR to avoid such exceptions when double-clicking on the JAR:

VIrtueeL, maybe you could run the game in command line to confirm whether you have the same problem, “the game does not run” isn’t very accurate, is it?

#8

The problem is obviously a pathing issue.

#9

Running Windows 7, couldn’t get it to work.
