Nice stuff, man. It's 3 am and I'm going to the army and from there straight up to a vacation for the weekend, so I'll try it out on Sunday or Monday.

Version 1.1
HERE
Latest changes:
- Cursor for making it more obvious where the tiles will be painted
- Fixed a bug where a line that started outside the cave and continued inside would suffer from submarining (i.e. the line would not be continuous if the cursor was moved quickly)

Other changes since version 1.0:
- White lines between tiles on the cave grid to help users measure distances (as requested by Soccerboy)
- Undo/Redo buttons
- Improved performance when painting in larger caves
- Terrain images replaced with grey rectangles to make undoing/redoing "generations" faster
- Images slightly reduced in size to make them look better in larger caves

whooo! and sorry to nitpick, but the white lines are sort of blinding. is it possible to change the color? if you agree, it seems like a simple addition. it's kind of hard on the eyes, maybe a light gray would be good? enough to differentiate but also not too... out there.

edit: may still be relevant, but i just noticed the release of the code and i could probably just do so to my own liking

I'll see what I can do.  

i edited that just as you posted

I could add a slider for altering the darkness of the measuring grid. Or an "easier-on-the-eyes" toggle. But I don't want to clutter the UI with lots of controls for obscure features that no-one uses. Maybe further down the line when I (possibly) have a menu system. But you're more than welcome to set up your own personal version in the meantime.

DECLARATION


I'm working on a cave, inspired by superanalytical mechanics.

Excellent! With any luck, you should have access to hotkeys by the end of today.

Version 1.1.1
HERE
Latest changes:
- Hotkeys. Copy to clipboard is sadly omitted due to browser limitations. I also decided to omit a Load shortcut as the hackery required just to open a dropdown list didn't seem worth it. The most useful hotkeys will probably be the ones for Undo/Redo (Shift+z and Shift+y respectively).

Hotkey guide is here.

shift? why not CTRL?

also, there was apparantly a storm tonight, so my cave is lost and I need to restart

what size should I make it?

I originally used Ctrl because this is what people expect to work. Unfortunately, if you change the cave's width/height/name, the browser tries to undo the changes you made to the values in there instead of undoing the cave changes. So Undo/Redo would break every time you changed the cave size. So I had to change to Shift to avoid bumping into that annoying override. I'll add tooltips for the weird shortcuts eventually. I don't like it either - it goes against the rule of UI design that says your web UI should behave how users would expect a desktop UI to behave. It may be possible to write a hack to prevent the browser from overriding the CTRL+Z undo. But for now, this was a simpler solution. It's better than no shortcut.

Oh man, why didn't you save???

As for size, I probably wouldn't go above 60x60. That said, zoom and pan is coming very soon.

EDIT: this could be a hack for disabling edit history in the forms, possibly allowing CTRL+Z to work. However, this also breaks the rule of UI design above and might have nasty side effects. I'll consider it, but no promises.

Version 1.1.2
HERE
Latest changes:
- Spike Filler brush: any space with terrain above or below it is replaced with an appropriate spike
- Spike Remover brush: spikes replaced by space
- Default cursor disabled when mousing over canvas

Zooming and panning coming very soon. Also an update on what's going on with CaveGen.

Version 1.1.3
HERE
You can zoom in and out by rolling your mousewheel (Mouse3). No more squinting your eyes at tiny tiles in huge caves.

I've also added panning - you can move around the cave grid in three different ways:
* Ctrl + left-click and drag
* Click the mousewheel and drag
* Arrow keys

Chrome provides the best performance as usual.

What's been going on with CaveGen?
Four months ago, I began the zooming and panning work and then stopped. Two reasons:
- I had a Chinese exam in June and I decided to write a web app to help me learn all the words in time. This took priority over CaveGen from April to June.
- Zooming is easy, but zooming without causing weird graphical glitches in the HTML5 canvas is not. Getting back into my workflow was tricky after not looking at the problem for a long time.

What's going to happen with CaveGen?
There are a load of awesome features that I want to add to CaveGen. Unfortunately, I'm currently going through a phase where I desperately want to build a portfolio of work online so that I can move my career away from where it currently is. So there will be other work that I will be turning my attention to soon. Therefore, my goal for CaveGen is to make it look pretty and then link it from the personal website I'm working on. There is a possible extension. If HATPC is still playable, I may consider building a miniature "hub" for people to share their CaveGen levels and interact with each other's caves in some way. Mainly for practising back-end web development and creating something to demonstrate to people I want to convince that I should work with them. If there are any enthusiastic/active cavemakers who are really itching for a particular feature that doesn't exist in the current cavemaker or in CaveGen, I may be persuaded to implement it...

Version 1.2.0
HERE
I've used Bootstrap to neaten up the UI a bit, adding a navbar, aligning buttons better and making their appearance a little less eye-bleedy.

You know what's ironic? Using cutting edge web technology to create a level maker for a game that's older than your average middle schooler

Super Mario Maker

I'm officially resuming development on this now that cavemaking is becoming viable again. I'm going to apply what I've learned about web development in my new job this year to convert CaveGen into a React application, this time with a back-end to persist caves properly and maybe even do authentication. I've also learned enough about CSS3 to fix the ugly layout. There's a laundry list of community-related features that I've always wanted to build into CaveGen, and with a backend I may finally be able to build some of them.

Back up to feature parity in terms of zooming, panning and painting.

BTW Jebby, if you were to want steel arrow crate textures, here they are: http://imgur.com/a/2BbME

Nice one, thanks!
