This mod changes the world generation screen to include a preview of the map as it generates. You can also pause, resume, repeat, skip, or cancel generation as you like.

For example, you can repeat the dungeon step to generate multiple dungeons. If you don't like how a world is looking, simply click cancel and you can start over.

Please let me know problems you run into.

Are you tired of running thousands of wires between teleporters? Or do you just want to make your wiring tidier?
Then you're in luck, because Wireless is a (yet another) mod all about wireless signals!

It adds Wireless Transmitters, Receivers, Transceivers and Remotes.

Fight some of the baddest bosses around! Or, fight some of the lesser bosses added for pre-hardmode!

This mod currently has;
- 10 unique bosses, 5 pre-hardmode, 4 hardmode, 1 true final boss (Tested with all endgame classes so it's very fair, just very difficult!)
- 7 minibosses, 3 pre-hardmode, 4 hardmode
- 135 items
- 12 enemies
- Extended throwing class
- The new final boss is spawned with materials obtained through Solar Eclipses, Alien Invasions and Pirate Invasions.
- Boss Checklist support!

Planned content;
- 16 bosses in total
- Lots more minibosses (Minimum 10)
- Tons more items (Hopefully a few hundred)
- Another tier to the endgame
- More regular npc's to flush out the game a bit (Hopefully at least 50)
- Extend the throwing class to hardmode (About 90% done)


1.6.7 adds:
- Added Worm Eye! Drops from Devourers. You use this to spawn the Grasper!
- Gave the Grasper a harder 2nd phase and expert mode AI! Also added an expert mode item and (so far) a new melee weapon drop!
- Gave the final boss his own theme! Also completely changed the sky modifier for him, he looks much more badass now! Basically, everything about him is improved. (He's much harder now)
- Nerfed the Full Restore a bit (Max stack size is only 1 now)
- Made all the bosses show up on the map again!
- Added the Dirt Yoyo! Toggles the class of damage (VANILLA) yoyos do upon use (Melee or thrown!), saved per-character!
- Did lots of balancing tweaks to the weapons post-moonlord! (The melee don't suck anymore!)
- Summoning item for the final boss requires more materials and is infinite now! Don't worry, if you had the old one you only need the new materials.
- Added the Imp lord! A pre-hardmode underworld boss for if you want one more step of gear before fighting the WOF.

Fast Start starts newly created characters with some gifts! You will be granted better than copper tools, weapons, gear and more!
Items given are randomly selected.

It's programmed as follows:
If you receive a platinum pickaxe, you can no longer get a platinum tier axe and hammer.
If you then get the next highest tier axe, which is gold, you can no longer get platinum and gold tier hammer!
This works the same for any other items so get, with some exceptions.
If you're lucky, you'll get both life AND mana crystals!

Can also grant things such as: slime staff, money trough, grappling hook and more!

Changelog for v0.5:
- You can no longer get Crystal Vile Shard as this is a hardmode item.
- Added Vilethorn as a replacement for Crystal Vile Shard.
- You can no longer get Diamond Ring as this item is worth a lot of money.
- You can now get Balloon Animal or Bundled Party Balloons as your vanity gifts.
- You will now get between 20 and 55 wood, stone blocks and torches.
- The amount of wooden arrows you can get is reduced by 100.
- The amount of throwing daggers and shurikens you can get is reduced by 10.
- If you are lucky, you can now also get a Wand of Sparking. That thing is dang hard to find sometimes.

Choose a class at the start of the game, then gain stats and perks relevant to that class as you kill bosses. Check the homepage for details on each class.

Each class has an active ability, by default bound to 'Q'.

Why settle for the run of the mill magic mirror or ice mirror?

More mirrors adds two new types of mirrors, each with a unique effect.
Only with the radiation of a teleporter, can these mirrors be made.

(v)Ersion is meant to enhance expert mode cooperative gameplay by increasing the gap between classes, providing each one the weapons and equipment they need to acomplish one given task such as tanking, healing, buffing or attacking.

Adds in endless items.

These items act similar to the Endless Musket Pouch / Quiver and some, such as the throwables, are the same but do not consume themselves.

Website URL changed from the TCF link to the Discord link, since I'm not active on the forums anymore.
Changelog is now on the Discord, due to limitations on text.

http://forums.terraria.org/index.php?threads/helpful-hotkeys.39382/

Adds helpful hotkeys. Change hotkey assignments in Settings/Mod Controls.

Cycle Ammo: Defaults to the Period key.
Cycles the ammo in the ammo slots. Quickly switch ammo to adapt to situations. Hold for 1 second to enable/disable Auto Cycle Ammo mode. In Auto Cycle Ammo mode, ammo is cycled each time ammo would be used.

Auto Torch: Defaults to the Tilde/Backtick key.
Automatically places a torch from your inventory in the world as close to the mouse cursor as possible. Great for placing torches quickly while exploring without worrying about aiming the mouse to find a suitable wall or tile to attach to.

Auto Recall: Defaults to the Home key.
Automatically uses a Magic Mirror, Cellphone, or Recall Potion from your inventory. No longer does your magic mirror need to occupy precious space on your hotbar.

Quick Stack to Chests: Defaults to - (Minus, like, get rid of this junk.)
If using a chest, Quick Stacks to that chest, otherwise, Quick Stacks to nearby chests. Simply a keyboard shortcut to the buttons. Just hold down the hotkey and run through your treasure room!

Smart Quick Stack to Chests: Defaults to \ (the \ and | key near backspace)
Like normal quickstack, except it is super smart. If you have a Wooden Axe in a chest, it'll place your Iron Axe in as well. Keep what you want to keep favorited. Solves Chest organization intuitively.

Quick Buff Favorited Only: Defaults to B (You'll want to remap the original Quick Buff)
Just like Quick Buff, but only attempts to use the potions that have been favorited (Alt-click). No longer need you fight bosses with Sonar, Fishing, Crate, Spelunker, etc potions.

Query Mod Origin: Defaults to the /? button
Hover over an item, NPC, buff, tile, or wall and a message will tell you which mod the thing came from.

Toggle Autopause: Defaults to P
Toggles the autopause setting.

Quick Use Item #20: Defaults to L
Use the item in slot 20. (2nd row, far right. Most useful for Rod of Discord and Money Trough)

Quick Use Config Item: No Default
Use the item specified in the config, regardless of slot, if found in inventory. Similar to Quick Use Item #20 but allows the item to be moved.

Swap Armor and Vanity: No Default
This will swap all armor in vanity with equipped armor, but only if the vanity slot is actual armor and not vanity. Hold for half a second to additionally swap accessories.

Swap Hotbar: No Default
This will swap the hotbar and the 1st row of inventory. Useful for swapping weapon and tool loadouts.

Cycling Quick Mount: No Default
A special Quick Mount hotkey that will cycle through all available mounts rather than just one. If used, simply replace the vanilla Quick Mount with this more versatile alternative.

Switch Frame Skip Mode: No Default
Cycles between frame skip off, on, and subtle.

Dash: No Default
Use this if you prefer to dash via a hotkey rather than the double tap method. There is a config option to disable double tap dashing if you want to avoid accidentally dashing the normal way.
