Discussing what can be added to Principia in future

It would probably be nice to add in future versions Principia some new details ... I always dreamed of seeing mini multi-emitter to fire your crafting projectiles! =)

I've thought about having the LuaScript object being expanded to morph into the model of any signaling object. Instead of it being like now where it has a single model with 4 outputs and 4 inputs, it'd be possible to turn it into the 1i1o object model, the 8-splitter model, the Robot Manager model... And be able to use all those sockets.

Basically it'd allow for creating custom objects written with Lua to a larger extent than we have currently.

Yes, that would be really great. =)

More Variable stuff can be helpfull

In what way? Principia Lua scripts already have all the variables you could need, and then there's the analog variables that can be set either through Lua or with the Var getter and setters. :)

Sublayer plastic beams would be a great thing, could finally color em with proper look!

Also search results could show levels that contain the searched words in the level description.

The metadata edit page was disabled due to someone exploiting some vulnerability in it to bring down the site. Someone needs to fully fuzz it to make sure it is safe but nobody wants to do it.

thats sad to hear:/ btw i think one kool feature would be hotkey for pivot/fixed interlayer joining, and also a feature that prevent any sort of movement and rotation of items that are attached to pixel or platforms EVEN in selectmode, thru a check option maybe. I had countles events where i realize after a lot that some parts moved tiny distance away because of that ( i now use the dragselect selection thing so i avoid that) ALso alterable behavior on fluid, like color, and the force with which the balls change size while taking speed / I will donate for the game in few days <3

just noticed my profile pic (small enough) doesnt show up

Yeah it was a bit unfortunate, they brought down the site for several hours while I was asleep right before the last contest was about to end. I think I found the vulnerability they used and have patched it, but I am not generally confident about the safety of the lvledit executable unless someone who knows how to properly fuzz something (not me) can verify it. I've sandboxed it for now which should mitigate any damage that may occur.

I improved the search page a bit. There is now fulltext search across both principia-web and the archive, a checkbox to also search in descriptions, and a checkbox to enable advanced boolean mode search.

Yes! I've always found it inconvenient that it defaults to the stiff connection with the keybind. It should bring up the connection type selection mode, where each button also has a respective keybind.

There's some unused code for multicoloured fluid, I haven't tested it but may be sorta functional. The fluid simulation in Principia is based on LiquidFun which has all sorts of other knobs that would be interesting to allow to be configured.

It needs to be smaller than 180x180, smaller than 80KiB and in PNG format. It's a bit picky, it should preferrably be able to resize profile pictures on its own by processing the image on the server but I didn't do that when I first implemented profile pictures and I haven't gotten to it yet...

I will donate for the game in few days <3

Thanks <3 I appreciate it. The server costs aren't very high but it's still one less worry for me if/when the operating costs for the project becomes fully self-sufficient off of donations.

YAY thanks i missed the png requirement, now it works.

I really love this game and Ill try pull up some ideas.

I think an useful feature could be item groups, for example i select 10 motors and make group "abc", when i click a motor it shows me the group it is part of, with the option to change motor force % of all grouped item, or not in case of need.

I would also increase maximum zoom-out in sandbox or game too, can be useful at times when drawing huge terrain or long stuff like rails.

New cables item, instead of arch between in and out (i mean the wire look itself) we could get a interpolar cable layout to better fit some builds.

More fractions for mulad or sub style items, with eventual manual input (example divide value by 3) and higher max multiply with same manual option input. / same for moving average, it would be cool see a value when changing its inertia value.

pure Delay electronic item, which apply X millisec before letting signal out.

Let all motors and servo to work also at +0.50/-0.50 values, which now disable them.

Increase linear alignment force on spring dampers, improve behavior of wheel item on painte terrain (jumps a little even on flat)

Multiselect menu could get feature to select a single layer instead of layer+everything on lower layer too (selecting all L2 stuff with L3 hidden to view will select all L2 and L1 stuff)

Sublayer planks should be changed so sublayer 1 and 2 won't hit a plastic beam on same layer (sublayer 0 and 3 already don't hit them), aswell as not hitting electronics or mechanical elements who occupy full layer height.

signal split items for power cables and interface cables so we can reduce number of CT's in case of needing to run several motors all the same way

to be continued :D

I would like more EXPLOSIVES! what about dynamite block which you can explode with signal, or explosives that will shatter objects in half and break them and then fire when power objects break and wood burns up.

GREETINGS ^_^

Absorbers should be able to absorb planks/beams/other items. Absorbers should also be able to detect if whether an absorbed bot was dead or alive, or what color (or alpha) an absorbed item was.

In the case of bots, a special absorber might be necessary - it could detect if any bot was absorbed and output a 1 at OUT0 and include a 1 at OUT1 if the detected bot was dead (or alive - could be user selectable). Alternatively, a bot absorber would need to be set to bot type (say, spike bot) and would output the same as the general bot absorber. This version would allow easier filtering for counting/scoring based on absorbed bot type.

As for beams and other objects, a "multi-absorber" might be cool - the interface could be a table that enables the user to select what item types and variants get absorbed as well as what value to output upon activation. This could enable high-destruction builds with lots of broken parts flying around which ultimately get absorbed so the user's device never gets bogged down.

Okay, so this one is a doozy and likely never going to happen, BUT: how cool would it be if there was some kind of integration with the Paul Falstad circuit simulator? I believe it's under GPL and technically possible, but also recognize what an extreme departure it would be from the base game. With that said, just think of the possibilities: you could build a custom circuit from the Falstad library and then import that circuit as an IC into Principia. This would bring real-world electronics into the game and massively expand what's possible as well as enhance the learning experience for the game.

The skin could just be an array of IO ports like the RC modules, and you would paste the code for your circuit into a dialogue box associated with that module.

I'm not sure exactly what the specifics would need to look like for integration and this is probably way too ambitious, but I think it's worth putting the idea out there at least.
