Physics Pet Game Features “Horrific Dogmorphs”

I love dogs. I love their pointy black noses. I love their round faces and round eyes. I love their pink and rectangular bodies. I love the wobbly way they pump their spindle legs when being sucked through a vacuum tunnel. I love dogs, and it seems as if this as-yet-unnamed dog physics project is going to depict everything I love about them if its devlog is to be believed. Come see these GIFs.

The game thus far contains dogs eating their dinner:

Dogs with big legs. “I still don’t know if the game has a place for horrific dogmorphs like this, but it’s something I want to think more about,” says the developer, whose TIGSource username is ActualDog. Coincidence?

Dogs bursting forth:

Dogs travelling:

There are a great many more at the above linked devlog, along with detail of the animation and AI systems thus constructed, and what the ultimate intent is for the project. For example, “I want the player to ultimately be able to have a pretty hands-on approach to training. Lots of encouraging/discouraging certain behaviors, pen setup and maintenance, making sure the dogs are getting along, feeding them, teaching tricks, etc.” There’s already some facility for praising and scolding dogs and for building them an environment like the one above.

There is obviously a lot of work still to be done, but I’m planting my flag right now by saying: I love dogs, and look forward to where this is going.

    Cute dogs. Their movement reminds me of locusts or ants or spiders, I can’t decide which of them is cuter.

    This is some stuff nightmares are made of.

    This looks like a nice project where the developer can learn some interesting stuff and has fun while doing so.

    The genetic algorithm-based development approach makes me think of Gridworld (which I was a little surprised to never see covered here), an evolution sim where abstract, scrambled creatures appear in a primordial soup until one happens to emerge with a combination of physiology and behaviour that allows it to actually survive and reproduce, complete with random mutations. Gradually, its descendants will develop more efficient bodies, obstacle avoidance, food seeking behaviour, hunting behaviour etc, none of which is actually coded into the program and all of which simply emerges through genuine natural selection.

    The gifs on the full thread are really worth looking at.
    Seems to show genetic fitness by literally raising the platform the “dog” is on, which I think is pretty cool.
    Also features a “leg” coming unattached and walking off on its own, which I think is totally horrifying.
    Anyway, even if the graphics get improved, pink rectangle and terrified-looking cartoon face need to be a secret mode. They are oddly compelling.
