Buster Bros Mode

Description
This mod adds 4 challenges that replicates the buster bros games, you are stuck at the bottom and you can only shoot up. you need to burst all bubbles to progress, you burst bubbles with just one tear, there's also some power ups to help you, the challenges also features the soundtrack from super buster bros from snes, it's exclusive to the challenges.

Your tears can break rocks

The challenges doesn't support coop.

In Easy, Normal and Hard modes you start with 15 extra lifes, each challenge contains 40 levels and you need to burst all bubbles before the timer runs out to pass the level, power ups can't be carried between levels.

In Panic Mode you start with 5 lifes and you will enter survival mode, bubbles will appear from above, you need to burst then to gain level, reach full level 99 and burst the remaining bubbles to win the challenge, taking damage on panic mode triggers a necronomicon effect and freezes every bubble for 3 seconds and you can touch the bubbles while they are frozen, and as a option if you want to go infinite panic mode you can press the button that appears next to the trophy.

If you leave the game in Easy, Normal or Hard mode you can continue from the level that you exited the game.

If you leave the game in panic mode you will instantly die if you try to continue that run, this is designed to avoid exploits.


Here's the power ups:

Holy Mantle

Kamikaze (burst all bubbles until only smallest bubbles remains)

Necronomicon (instantly used and removed when you pick it)

Odd Mushroom (tears up version)

Ouija Board

Soy Milk

The Hourglass (freeze all bubbles for 3-7 seconds (it's random), you can touch the bubbles while they are frozen)



Here's the bubbles:


Red: bounces on the ground, the height that it can reach is fixed for each size, splits into 2 smaller versions

Dark Red: bounces on the ground, the height that it can reach depends of where it was spawned, splits into 2 smaller versions, in panic mode when destroyed they freeze all bubbles for 2 seconds, you can touch the bubbles while they are frozen

Blue: bounces around the room going into diagonal directions, smaller blue bubbles moves faster, can go to 4 fixed directions, splits into 2 smaller versions

Dark Blue: bounces around the room going into diagonal directions, smaller blue bubbles moves faster, can go to 8 fixed directions, splits into 2 smaller versions, in panic mode when destroyed they freeze all bubbles for 2 seconds, you can touch the bubbles while they are frozen

Gray: can act as a Red or Blue bubble, what it do on death depends of it's pattern, bouncing on the ground spawns red bubbles, bouncing around the room in diagonal directions spawns blue bubbles, bouncing on the ground and pulsing spawns red and blue bubbles

Darker Gray: Same as Gray version, but spawns only Dark Red and Dark Blue bubbles

Rainbow: bounces on the ground, the height that it can reach depends of where it was spawned, drops a power up when destroyed

Glowing Hourglass/Remote Detonator: Exclusive to Panic Mode, the rarest bubble, bounces on the ground, the height that it can reach is very high, initially appears as the Glowing Hourglass version, when bounces switch to Remote detonator and vice-versa, when destroyed showing a Glowing Hourglass it freezes every bubble for 7 seconds and you can touch the bubbles while they are frozen, when destroyed showing a Remote Detonator it damages every bubble in the screen 5 times


it's recommended to play this mod with 16-Bit Renewed for a better experience

Enjoy!

hci7t5r98t97yp0uo0gi8d56 power ups are fixed for levels, I already added all levels and I don't plan to add more levels or level packs, so no new power ups

Initially I learned reading the code of mods that aren't mine, specially mods that add enemies like revelations and hardmode major boss patterns, after learning what most of the functions do I didn't needed to see the code of others mods anymore, but it took a lot of time, like I tried this in the release of afterbirth plus (at the start of 2017) and I started to fully understand around the end of 2018

epic, i have 1 question. where did you learn to code becuse i want to make wacky shit like that:lunar2019piginablanket:

reading the last comment could make you think that it is hard to code, but was the easiest part
Guilherme  [author] 30 Sep, 2022 @ 12:15pm 
the rest wasn't hard to code, just took some time to code, like when the player dies with the hud still showing extra lives I just give to the player lazarus rags when the collision with a bubble happens or time runs out and when the player revives I transform him into isaac again, I set the values to spawn the correct waves for the levels, saved the values to the player leave the game and return in the same level that the player leaved the game, the black screen transition is a giant entity that covers the entire screen, the power ups was also easy to do, like some of then just give the item to the player, with some exceptions like kamikaze sets a value to damage every bubble with the exception of the smallest ones, necronomicon damages the bubbles, hourglass sets a random value that while active the bubbles can't move and the player don't have collision with then, and at the start of each wave the player loses every item

enjoyer the hardest part was making the red bubble physics, because there's no function to detect collision with grid from specific angles, but after knowing other ways to do it I made the bubbles, the levels also took a while to think, because the idea was to create 120 levels for the easy/medium/hard challenge and I didn't have much ideas for the levels, so took like 1 week to create all the levels.
