ExpandTheGungeon

ExpandTheGungeon (BepInEx Version) - by Apache Thunder.

Features:

1. Updated version of old Anywhere mod. Use load_flow to load a DungeonFlow. Command syntax is mostly the same as old anywhere mod. Use "load_flow help" in console to get help on how to use this command.

2. Three new secret floors! Both with brand new tilesets pulled from unused tilesets from old versions of the game.

3. Glitch Chests now take player to a full floor with glitched enemies instead of just a simple 3 room floor that goes direct to the boss.

4. Fixed pit generated under sell creep on floor 4. Pit edge decoration of floor tiles near left side of sell creep is no longer missing.

5. Fixed issue intreduced in FTA update that made it trouble-some to drop passives into sell creep in Bello's shop.

6. Added "Junk" enemies. A small chance a floor could have 1 or 2 critters that spawn Junk or Ammo when killed depending on which enemy was spawned. This was an idea from TheTurtleMelon so credits to him for this one.

7. Added custom rooms to room tables used by most floors. This adds new room layouts to the game! Most room designs courtasy of TheTurtleMelon!

8. A glitched elevator has a small chance of appearing on the floor. This takes the player to a glitch chest floor. Can only appear on rooms 1-4 and can only appear once in a run.

9. The few Winchester gun game rooms that were missing icons now have icons. This oversight from original game devs has been fixed.

10. Custom secret rooms. Staring with a ultra tiny secret room that is the smallest possible size (2x2). This secret room can appear in places you won't expect one to fit so be on the look out!

11. Glitch Floors have "corrupted" appearence via addition of sprite objects that use random tile map sprites.

12. Additions/Improvements to DD20 modifiers:

• Rat's Revenge now spawn rat traps instead of flame traps.
• Infamous bug with Zone Control possibly soft locking the player if teleported out of room is fixed.
• Don't Blink is changed to have enemies have stone effect instead of boring stun effect.
• Blobulon Rancher can now spawn poisulins as well as the normal blobulins.
• Two new DD20 modifiers. "Apache Thunder's Revenge". A custom modifier that has most of the Chaos mode mayhem from ChaosGlitchMod!. The second modifier is "Triple Trouble. A modifier for the Trigger Twins boss. As you can guess a third trigger twin will spawn.

1. Custom items!:

• "Baby Good Hammer". An active item companion that summons a Dead Blow Forge Hammer to do your bidding! Thanks to Retrash for providing the item sprite.
• "Corruption Bomb". A powerful bomb that corrupts the reality around you. Corrupted enemies can no longer attack. May have suprising effects on other objects. Test it out on things if you dare!
• "Table Tech Assassin". Tables flipped by enemies are betrayed by their tables. Tabled flipped by enemies explode.
• "Corrupted Junk". Junk warped by corruption. May grant player an obscene amount of a random consumable.
• "Cronenberg Bullets". Bullets that have a chance to transmorgify enemies into a horrible cronenberg abomination. Sprite work courtasy of Neighborino!
• "Mimiclay". Special item dropped by custom boss on custom secret floor. One time use active item. Clones another active or passive when used while said active/passive is spawned/near the player. This item idea/code was created thanks to Retrash.
• "The Lead Key". Special active item taht will teleport the player to a new room not normally connected to the floor. Small chance of beign a shop, shrine, or chest room.
• "The Bullet Kin Gun". Fires Bullet Kin....No further explenation needed.
• "Baby Sitter". Companion item that gives you the COOP cultist as a non playable friend. Like Cop, he can die. When this happes you get curse and damage up.
• "Rock Slide". Causes rocks to fall on your enemies! Amount of rocks is random. Sometimes all enemies get targeted while other times only a few do.
• "Pow Block". Flips enemies and makes them easier to kill. Flipped enemies can no longer attack.
• "Clown Bullets". Bullets have a chance to transform enemies into clownkins.
• "Clown Friend". A Clownkin friend followes you around and wields a balloon gun! Balloons caried by this friend can cause small blank effect when popped by enemy bullets.
• "Portable Elevator". A portable elevator for a quick escape. Takes you to a secret floor!
• "Portable Ship". Transforms the player into a ship until the player is damaged.
• "Sonic Box". Sonic the Hedgehog comes to the Gungeon!
• "The Third Eye". Allows viewing rooms not yet explored. May cause some corrupted enemies to appear.

1. Certain NPCs and objects and even a copy of the player can appear as enemies on glitch floors.

2. An unused trap "Alarm Mushroom" has been revived and made usable. It currently appears in random rooms on the Mines, the floor the trap object was intended to appear on.

3. New type of elevator added. A small elevator that can take the player to another room on the floor. Used as a entrance elevator to the secret glitched elevator room on Hollow.

4. 1 new Custom Boss! Can be found on my custom secret floor!

Adjustments made to combat loop trigger system for custom floors. Now when player enters floor for first time, a combat music track loop will not trigger until at least after one room of combat (two if on old west since entrance is combat room). This is so main track has a chance to play longer before a combat loop switchs it out.

Fixed mistake with Ammonoicon entry for Tuc who's description was accidently left as a duplicate of Angel (the Old West Bros boss fight on Old West floor)

v2.9.11:

Fixed potentional lag issue involving custom logo if Frost and Gunfire mod is installed.
Mod will now display text above the main logo for the mod name/version instead of the main graphic if Frost and Gunfire mod is installed since Expand's logo texture would be overridden by that mod.

Fixed issue preventing Skusketlink from being added to Ammonoicon. It has now been added.
All previous Ammonoicon entries now have unique EncounterGUIDs. You may need to re-encounter them to see them again. ;)

v2.9.9:

Fixed code with skuskethead/chameleon ammonoicon addition that broke level generation of Jungle/Belly. This unfortunately means skusket head no longerh as an ammonoicon entry as I could not get it work without breaking Belly level generation.

TheLeadKey can no longer teleport the player to an inaccessible area in Winchester rooms and should be a playable winchester room.
TheLeadKey will automatically remove enemies that overlap the area the player will be teleported to which should cut down on players taking unavoidable contact damage.
One of the custom secret room layouts for the Witch NPC resulted in guns spawning in a hard to reach area or glitching into the wall. The layout has been adjusted to address this issue.

v2.9.4:

Soft Lock issue with Gunslinger when encountering Dopplegunner boss has been fixed.

Enemies killed after being affected by Pow Block now have their sprites fully unoccluded so they can be seen dropping over walls/other obstructions that would normally obscure their sprite.

Rewrote most of special elevators used to take player to the exit room that leads to Old West on Hollow. Issues where the elevator stops working if player teleports away without using it after opening/unlocking elevator should be fixed.

MidGame saves now go to the correct floor after doing a midgame save from custom floors in ExpandTheGungeon. (custom floors from other mods not guranteed to work)

Old West floor layout altered. Rat, forge shop, and forge exit are now removed from floor and replaced with DoppleGunner. Where DoppleGunner used to be is now where the new Old West boss spawns. Exit elevator moved from fake boss path to the main boss path so beating the new Old West boss is required to exit the floor. The alt exit with the shortcut to bullet hell/past has been removed for now. Might get added back pending any feedback.
New screen shader fx for glitch chest/glitch elevator floors. New screen shader for glitch floors can be disabled in ExpandTheGungeon_Settings.txt if unwanted.
New screen shader fx for intro of new Old West boss.
The Lead Key now has chance to spawn corrupted copy of room the player had used it in (this will even work with custom rooms from other mods!). No benefit when this happens other then as a surprise and to balance it out by resulting in a little less instances of shrine/chest rooms being spawned. ;P
The Lead Key now spawns a portal that allows quick teleporting back to the previous room once player has finished with the room they were taken to. Minimap for generated rooms and teleporters have been disabled so be sure to do what you need to do before leaving as there won't be a way back!
The Lead Key has new transition FX for teleporting to new room. The effect is based on the FX used in Axiom Verge 2 when entering/leaving the breach. This FX uses a new shader sourced from this repo: https://github.com/khalladay/GlitchFX
The Lead key can no longer be used in exit hallways to avoid a bug that could occur in some circumstances.
New trap room containing a new kind of chest!
Setting added to allow enabling the old glitch chest behavior if you don't want to do a full floor to get to the double beholster fight.
Moved Tileset serializd text files into asset bundle to reduce DLL file size.
Phobos tileset now added and made working in ExpandTheGungeon. Currently will be used as a glitch floor tileset. Can be accessed via load_level mod as tt_phobos.

Missing Pit bubble animations for Belly fixed via PitAmbientVFX in the room materials.
New sprite collection serialization system setup and all assets are now using.
Fixed missing minimap icon for Jungle tree room on floor 1. (there was always meant to be one there but at the time I couldn't figure out why it wasn't working. :P )
Rats on special elevator room on Hollow replaced with Old West equilivent enemies.
Redesigned special exit room that leads to Old West on Hollow.
Shoutout to GoldenRevolver for helping with some code improvements and for setting up West Bros boss!

v2.4:

Added ability to save certain mod settings to external file. This allows certain things like youtube safe mode switch to retain it's previous setting. Using the switch on the entrance room on floor 1 will generate this file along with using the new console command: "expand savesettings".
New language override feature. Allows a workaround for users who want to use the game with certain languages without breaking MTG console GUI. To use this feature, set the game to the language you want to use, then use the command "expand togglelanguagefix" to enable the feature. The mod's settings file is automatically saved when this command is used. Using the command again will disable the feature and reset the game back to English. Note you do not have to set the game back to English prior to exiting. The game will be set to English on startup if this feature is enabled. Game language gets set back to your intended language after you select a character at the breach. This gets around the issue of the console breaking with certain languages. (Japanese, Korean, Chinease primarily. Though some other languages may also break the console GUI)

v2.3:

Belly Boss HP reduced a little.
Cursed Brick added to Cursola's item pool.
Fixed oversight in Wall Mimic code that could cause an effect similar to Cursed Brick (Wall mimics in almost every room) if RewardManager decided to place one or two normal wall mimics on the floor. Normally you must have Cursed Brick to have nearly all rooms have a Wall Mimic.
Improved code in WallMimicController's Update function to help reduce any possible lag/frame drops that would happen when floor has a lot of Wall Mimics placed due to Cursed Brick.

v2.2:

Fixed bug that could cause Wall Mimics to be more rare then normal.
Added new item: Cursed Brick (sprite courtesy of SomeBunny). Item that can't be dropped. When picked up causes almost all rooms to have at least one wall mimic.
Corrupted Junk now has a chance of causing up to 2 random rooms on the floor to become "corrupted".

v2.1;

Fix bug that caused most bosses for Pasts to not activate correctly which would cause a softlock for players intending to clear a past.
Sound bank and custom asset bundle filepaths are now generated from mod meta data instead of using preset strings. This should allow users to have what ever filename/folder name the mod that they want without breaking the mod.
Adjusted code related to enemy name localization to better improve compatibility with other mods.

v2.0:

Old West now has it's own set of custom rooms thanks to TheTurtleMelon.
PowBlock icon will now correctly reset when used in a room where there are no enemies it can be used on. (bosses and non room clear type enemies)
Alarm Mushrooms no longer spawn in boss rooms on Mines. (this can potentially cause issues with Tank boss and cause it to get stuck)
Glitch Elevators should no longer spawn in any room where tilemap is disabled. (rooms like Bootleg room for example)
Fixed bug with Pow item that caused exceptions if used in a room that has a Displacer Beast.
Drill should now work properly for chest room chests on Jungle secret floor.
The Lead Key will now spawn the player at a preset location in the target room if it happens to be an Exit Elevator room to prevent accidentaly leaving floor due to random spawn placing player directly inside elevator area.
Rick Roll chest now drops a C or B tier item upon opening. Destroying it will still yield junk however.
Improved code for randomly placed objects like Wall Mimics, alarm mushrooms etc. This should hopefully resolve rare issues with objects paranted to incorrect rooms in cases of custom rooms that aren't trimmed properly.
First secret path on Old West floor now requires 2 blanks to fully access instead of 1. Older versions of this floor had this intended layout but forgot about it when it was remade with Old West tileset.
Large pixel art rooms removed by request from TheTurtleMelon based on feedback from him/other players.
Trap room full of saws now only appear on Sewers and the Abbey instead of all normal floors to reduce occurance and according to player feedback.

v1.9.7:

20+ custom rooms for Mines have been trimmed to reduce visual bugs with spike decorations appearing in rooms they should not be in. (like Shop or elevator room). This should also reduce instances of rat trap door appearing in boss rooms.
Odds for Gltich Elevator reduced again. Now 0.3% odds per floor instead of 1%.

v1.9.6:

Candle Guy enemies no longer leave eternal fire goop if they are placed in rooms that aren't boss rooms.
