Tool TerraCustom for 1.3

This is the updated TerraCustom for generating world for Terraria 1.3. (endorsed by the original author)

This standalone executable will generate a Terraria world guided by your input. You can choose background images, ores, crimson/corruption/both, Dungeon Size, and many, many more options to create a world to your liking. Want a world with high mountains, both crimson and corruption, a huge Dungeon, and no Pots? You can make it, or whatever other world with TerraCustom.

Also compatible with tModLoader mods and Leveled RPG mod generation.


I am open to suggestions for future iterations, especially since much was added in Terraria 1.3. Also, the code is open sourced on GitHub, if you can code, I would love to make this a group effort. I'll guide you in coding your first feature.

Latest Download: jopojelly's TerraCustom v0.6.2 (tModLoader 0.11.5/Terraria 1.3.5.2) (works with 1.3.5.3 too)
For Windows | Mac | Linux -- Download
(note, to play extra-large worlds, use Large World Enabler)
(note, to watch world gen use WorldGen Previewer)

Install and Usage:
READ the file called README.txt.
I'll be very disappointed in you if you ask something that was answered in there.

PS: Let me know if you find anything that doesn't work as expected. Much credit goes to PinkPlum for the original.

One feature I've wanted, although I'm not sure it is possible, is to determine how many corruption or crimson biomes spawn. For example, generate a large world with only one corruption biome, or a small world with four crimson biomes, or a medium world with one of each.

also disabling the generation of both would be cool.

You're a hero and PinkPlum would be very happy to see this. Who knows, maybe the two of you could team up eventually?

Will this also work with the GoG version?
I'll try to comment out the steam stuff that's still in the source so that a version soon will be.

I'm looking into all the suggestions as well, keep em coming.

I'm working on some stuff right now, like Enchanted Sword Shrines (this is an extreme example.)


Also, I just wanted to mention that having 100 times as many traps sounds a lot more fun that it turns out to actually be.
 
From what I remember, the original TerraCustom was compatible with GoG, so hopefully it won't be too hard to keep things running if you're working from the original TC source code. Also, a nice feature to have would be an ability to have more jungle shrines, if only to find those blasted flower boots. It would also be nice to get more chests at cavern level, as the lava charm is probably the single greatest sticking point upgrade wise in the game.

Finally, that pic with all the traps is hilarious; all we need now is for all the traps to be dynamite, and for tripping the whole mess to simultaneously play the theme for Fallout 3 (I Don't Want to be the One To Set the World on Fire).

Nice. Maybe an option to choose how many granite and marble biomes will be created? Also an option for the amount of sword shrines would be nice.

Something I noticed: some of the options don't 'save' properly and reset to RANDOM if you reenter the menu, such as tree style.

Got dynamite in there now. Also, I'm pretty sure it will work with GoG version now, please let me know if the new version works for you.



New release: v.11 v0.1.2: Enchanted Sword Shrines, Traps, Dynamite Traps, unshackled from Steam.
