A powerful map editor and viewer for Windows. Its countless features can be used to copy. TerraMap online is an online model of the Terraria map viewer for PC. The benefit is that that is a cross-platform Terrain viewer that still keeps its PC counterpart’ features. Terraria is a chunk-full of surprises, which permits gamers to discover significant worlds looking for hidden treasures.

Background Information

TerraMap uses only a single pixel and color for each block, tile, wall, item, etc. It does not use the game's textures. For that, I highly recommend the excellent Terrafirma.

It's built using JavaScript, JQuery, and Bootstrap. It uses Web Workers to do processor-intensive work in the background to improve responsiveness and performance.

I experimented with several different approaches to drawing, and finally ended up using HTML canvas 2d context fillRect method, which is the fastest method on Chrome, my current browser of choice.

This was an education exercise for me. The only real improvements I made over Terrafirma are the combined block/tile/item search, allowing you to search for items in chests, the incremental search forward/backward, and UI improvements.

I referenced the Terraria .wld format documentation provided by Terrafirma to read the world data. Sean definitely did a great job at reverse-engineering and documenting the format. Portions of TerraMap code were adapted from the source code for TerraFirma and TEdit. I also used ILSpy to peek at some of the Terraria game code.

I used the excellent jquery.panzoom for pan and zoom functionality.

Cave Story is a game developed by Daisuke Amaya aka 'Pixel.' During quarantine I decided to recreate the entire game in Terraria now that 1.4 is out with Journey mode and there are cool new building blocks to work with. The World can be played like an adventure map, or you could just tour the areas and explore what Cave Story has to offer.

Main Features:

-Terraria 1.4.x compatible!
-Wide variety of areas with all sorts of rooms and caves.
-Up to 2 players recommended, though I'm not stopping you from running through the place in Journey Mode with 8 other people.
-Mining and building is not allowed and not intended for progress.

Terraria World Editor 1.4

How to Play:
-Do not change NPC houses or create new ones
-Do not change any wiring/teleporter setups

-You can use Boss drops, except for the Slimy Hook and Slimy Saddle. Both provide way too much mobility for something that can be obtained near the beginning of the game.

Useful Tips:
-Keep an eye out for Pressure Pads during the early game. They're deadly!
-Save up your coins, you'll be able to Reforge equipment later on.

-Don't overestimate yourself just because you think you have powerful enough gear.

How to Install the Map:
-To play the world, download it, and extract/unzip the folder. Copy '________.wld' and past it in your world saves folder, which by default should be located in: Documents > My Games > Terraria > Worlds.

If you have any feedback then please feel free to tell me.

*This project can go further, with bonus areas such as the Wind Fortress (G-Clone) and the Inner Wall (Prinny Cap) not built yet. If the world receives enough downloads, support, or I become bored again, I may update the world. The teleporter hub area is also a little bit rough around the edges too, but I'll take function over form for that detail.
