Graphics of the Evening #2

If it's cold in your room, then there is the following mod. Another useless application of our engine: just ray trace a simple scene written completely on JavaScript. The mod is attached, feel free to play with it.

Very nice, you might like to try the same with ray marching.

@vladislavbelov ok from what I understand you created a new special font where you map one glyph to one RGB color and then each line is broken with an non printable "\n" codepoint. Each glyph is just a rectangle?
I wonder if it would also be possible to just use the block code  character and then for each one (or range) add a <color > tag around (then no new font needed). Still don't know how you did the raytraced font. Would be cool to make these kind of posts something like an ester eggs or a 0ad blog entry.

Fun nonetheless. (at first I thought you used some new pyrogenesis <canvas> object but seem not)

Feels like that would be worthwhile now we have a canvas class. Drawing lines seems nice.

Uff, for some reason after using the mod alpha 24 won't work. The mod is disabled but now when 0ad 24b is open it shows a black window, nothing more, no crash, no logs. I tried deleting user config, cache. Will try to reinstall now.

Edit, its alpha 24 not 23

Yeah, I was experimenting with it:

Yes, square for each R5G5B5.

It's possible but more slow, as on each frame you need to do a lot more work for rendering.

Just generated by a script.

We don't have a blog, so I just post some of my local stuff on the forum.

It's impossible without performance loss at the moment.

Cleaning up the cache should help, because there should be no other relation between mods.

Ok found the cause, seems some data got written to Documents/My Games/0ad/mods/user for some reason and deleting it fixed it. @wraitii you might want to check this as it I find it weird that fonts from the mod get stored there (which means that they get executed even when no mods are enabled)

[wraitii]

Mh, this would make sense actually if you're not in a dev copy & the mod writes data.

Edit: seeing how you played this with A24, it's definitely 'expected behaviour'. The issue is that the mod shouldn't be writing data like that tbh, but given it's a hack, meh.

I dislike the user mod in general and would probably favour doing things differently, but it's not a 'bug' for now.
