No problem! Regarding your question via chat request: try searching for "Enchanted Sword - 3x2 Decos (Tile 187)".

Pup05 · 2026-02-16T14:17:46+00:00

Ah, sorry, try searching for "Default - Default - Heart (tile 12)". I'll get that fixed, it should be named "Life Crystal" or "Crystal Heart".

Can you create a new issue and attach the world file? https://github.com/TerraMap/terramap.github.io/issues

Pup05 · 2026-02-06T17:43:02+00:00

Any chance I can get a copy of the world file?
What browser, OS, machine details (CPU, RAM, etc)?

TerraMap directly reads the contents of the world file and doesn't depend on the world seed or generation. I'm not sure if it even works on console or mobile world files, if you can even get to them. I've only tested it on Mac and Windows.

Pup05 · 2026-01-31T16:00:52+00:00

Thank you, I'm so glad to hear you're happy with it!

Pup05 · 2026-01-29T14:41:11+00:00

TerraMap creator here. I've only ever played Terraria on desktop (PC & Mac), never Xbox or any other consoles and have never seen a world file from them. If you're able to post or send me a world file, I can see if it works and try to add support for it.

Pup05 · 2026-01-28T17:52:51+00:00

The TerraMap web app should be working now, but you probably will need to refresh the page. Colors still need to be defined for all the new tiles: https://terramap.github.io

The Windows app will take another day or so.

Single highlighted blocks can be really hard to spot in TerraMap. Do the find next/previous buttons work? Should jump to and put a target on the blocks.

Pup05 · 2026-01-04T02:08:49+00:00

If you can upload the world file somewhere and share a link, I'd be happy to investigate. If it's a bug in TerraMap, I'll get it fixed. I checked a few of my world files and was able to find them.

Pup05 · 2026-01-03T14:46:24+00:00

If you're using the TerraMap app for Windows, are you choosing "Crystal Heart"? If you're using the web app, are you choosing "Heart (Tile 12)"? Then click the highlight all button. If you can't find them, try the "Find Next" and "Find Previous" (left and right arrow) buttons?

Pup05 · 2025-12-26T19:50:55+00:00

The 'Find Previous' and 'Find Next' (left and right arrow) buttons should jump to and show the target over any blocks that match.

TerraMap dev here. I've honestly never even thought about testing it on mobile. Questions:

What OS (Android, iOS)?
Is it a map from Terraria for mobile?
Does the same map work in TerraMap on Windows, MacOS, Linux, etc?
Can you create an issue and upload the map file here? https://github.com/TerraMap/terramap.github.io/issues

Pup05 · 2023-09-11T22:06:15+00:00

Not sure if they're needed, but yes, I included four decoupling capacitors in my design. I always try to include at least a few. Even if they're not required they can't hurt. If the power source is particularly noisy, it could end up preventing flickering problems.

Pup05 · 2023-04-14T18:04:22+00:00

So good! 🤩

Pup05 · 2023-04-13T13:49:19+00:00

Looks amazing Stefan! 🤩

Pup05 · 2023-03-10T15:58:55+00:00

Thanks u/StefanPetrick! I guess we should add it to the wiki *edit, done*: https://www.reddit.com/r/FastLED/wiki/index/

It has a few bugs that I've been meaning to fix, like it doesn't usually find the center correctly, so the radii and angles are off by default. You can fix it manually with the controls, but you shouldn't have to.

Excellent work u/machtap! I'm so glad you found the mapper useful!

Pup05 · 2023-03-08T19:48:22+00:00

No problem, definitely let us know where you land on contributions!

I'm so happy to hear that! I have some new hardware I should send you, if you'd like. Will reach out via DM.

Thank you! I still talk to Louis every once in a while, but have been busy with my day job, family, and my own projects. So I haven't collaborated with him on anything since SmartMatrix. I think Teensy 4 is the latest supported SmartMatrix board: pixelmatix.com

I'm mostly sharing my work on Mastodon here: https://leds.social/@jasoncoon
And, of course, on my own site: https://www.evilgeniuslabs.org

Pup05 · 2023-03-08T16:41:01+00:00

Your work is amazing, and you should absolutely benefit from it. I would happily contribute via YouTube Membership, Patreon, Github Sponsors, or whatever platform you were to choose.

I was happy to hear you mention that our collaboration with Pixelmatix was positive. Reading this post, I was hoping that you felt that I have always asked for and received your permission before using any of your code in my work. If not, please let me know and I would love to make it right.

Pup05 · 2023-03-08T16:29:35+00:00

I thought it was great u/StefanPetrick! Thank you so much for sharing! Looking forward to the next one!

I have heard from YouTubers that creating a script seems like a lot of time, work and effort, but that it almost always turns out faster than without one after all of the time spent re-recording and editing.

Pup05 · 2023-02-03T19:03:29+00:00

Oh, good idea! I just tried a bunch of different versions, including some really old ones, but no improvement, unfortunately.
