Bomb mode and Item Blocks

[KirbyJoe]

Introduction

Long time ago, I posted an issue to add Bomb mode (which is inspired from Bomblin) and Item Blocks on Nullpomino's Github page, but since the development of Nullpomino is not active for a long time, I moved it to more active ModePile mod.

When I discovered ModePile, I thought it's possible to implement Bomb mode and Item Blocks with ModePile for its use of custom libraries. ModePile can also implement additional graphics and sounds, which are used in some modes.

Bomb mode

The Bomb mode is based on BomBliss aka Tetris Blast, which is featured on many games including "Tetris 2 + BomBliss (not related to Tetris 2, a North American version of Tetris Flash)". In the original issue, I suggested the modes based on a BomBliss clone game called "Bomblin" to make the mode also functions as a replacement of that, which is no longer published by the creator AOiRO_Manbow. But I noticed that only few people have that game for now and I think it's not possible to make a Bomblin-based modes right now, so the idea of Bomblin-based modes is currently on hold until I play Bomblin.

• Bomb Puzzle: Same as Puzzle mode from Tetris 2 + BomBliss/Super Tetris 2 + BomBliss and Super BomBliss.
• Bomb Contest: Same as Contest mode from Tetris 2 + BomBliss/Super Tetris 2 + BomBliss, Super BomBliss, and Tetris Party Deluxe.
• Bomb Dig: Same as Bombliss Plus mode from Tetris Axis.

Rules for Bomb mode

The following rules are recommended for Bomb mode:

• STANDARD
• NINTENDO-R
• BPS-NINTENDO

Bomb mode uses a same rules from Tetromino modes. Non-tetromino pieces are appear like using an option on Practice mode, meaning it doesn't need a custom randomizer for the mode.

Item Blocks

On Tetris clones, the item blocks from TGM are implemented in Heboris Unofficial Expansion along with its own items. I originally requested to implement the ones from TGM, but on this ModePile issue, I also add the ones from Heboris UE, which includes some items based on Tetris DS and Bloxeed. Note that the item blocks and Hard block (mentioned below) should have its own blockskin, which is separated from normal blockskins. This will also implement the assists on Score Mania (it should be added as a mode-specific option, otherwise the replays that are recorded before the installation of ModePile will be broken). Use Heboris C7EX as a reference when you create the item blocks for ModePile, which can be downloaded here: http://mufunyo.net/tetris/

The following item descriptions are based on, and taken from a Japanese TGM glossary and the TetrisWiki page of Heboris UE (you can also check the effect duration and frequency of the items on the wiki page):

TGM Items

Attack

• DEATH BLOCK: Makes the opponent's NEXT piece bigger. (No effect in BIG mode)
• 180° FIELD: Makes the opponent's stack upside down.
• MIRROR BLOCK: The opponent's stack is mirrored 3 times for each new piece, leaving it mirrored after the 3rd piece. (Added from T.A.)
• SHOT GUN!: Randomly shoot a group of holes in the opponent's stack.
• HARD BLOCK: The opponent's NEXT piece must be cleared twice to be removed from the playfield.
• LASER: Deletes a column of opponent's field (Can add a extra column (up to 4) to delete by pressing player's button rapidly).
• ROLL ROLL: Makes the opponent's three NEXT pieces automatically rotate counter-clockwise (While the item is active, it'll make the opponent's piece white).
• TRANS FORM: Makes the opponent's three NEXT pieces change its shape when the opponent press the rotate button (Can rotate them only by initial rotation).
• X-RAY: Makes the opponent's field partially invisible with "scan"-style effect.
• COLOR BLOCK: Makes the opponent's field partially invisible with patternized flashing.
• DARK BLOCK: Makes the opponent's field invisible. (Added from T.A.)
• NEGA FIELD: Inverts the holes and blocks in the opponent's field.

  Defense

• ↑/↓DEL FIELD: Deletes the up or down half of the player's stack.
• →/←MOV FIELD: Gathers the blocks into right/left side of the player's stack.
• DEL EVEN: Deletes the even-numbered rows of the player's stack.

  Special

• FREE FALL: Fills every holes by drop all blocks in the player's field (There's a backfire glitch in T.A.'s singleplayer modes that makes the garbage sent into yourself after you clear the lines with this item).
• EXCHG FIELD: Swaps the player and opponent's field (No effect in singleplayer).

  Heboris Items

  Attack

• ROTATE LOCK: Lightning from Tetris DS. Disables the opponent's rotation and turn opponent's pieces gray. The orientation of opponent's NEXT pieces are randomized.
• HIDE NEXT: Boo from Tetris DS. Temporarily hides the opponent's previews.
• MAGNET BLOCK: The opponent's fall speed increases by 0.5G. Pieces will lock instantly while this item is active.
• TIME STOP: Opponent's active tetromino is frozen in position. Opponent is unable to perform any commands.
• HOLD LOCK: Disables the opponent's hold function. (No effect in rules without hold function)
• →←REVERSE: Reverses the left and right movements of the opponent.
• BOOST FIRE: Opponent's tetromino fall speed becomes 20G. It halves the opponent's lock delay if they are already at 20G.
• ↑↓REVERSE: Opponent's up and down input keys are switched.
• REMOTE CONTROL: The player takes control of the opponent's inputs including Hold, while maintaining control over their field. It also disables the opponent's inputs.
• SHUFFLE FIELD: Opponent's rows are shifted randomly left and right. The empty columns stay connected only if the rows containing the columns are filled with 9 blocks each.
• DOUBLE: Increases the lines recieved from the player by 2. (No effect in singleplayer)
• COPY FIELD: Opponent's field becomes the player's field. (No effect in solo mode)
• FAKE NEXT: The piece previews and the held piece become fake, but the colors will be the same as the original piece.
• GRANDMOTHER BLOCK (stylised as [ ] BLOCK on low-res sprites in Heboris UE): All blocks will turn into "[ ]" blocks.

  Defense

• REFLECT: (VS) Opponent's item attacks are reflected to themselves. (Others) The player is protected from one attack type item.
• ALL CLEAR: Clears the field entirely.

  Special

• FEVER!: Super Star from Tetris DS. All of player's NEXT tetrominoes become I tetrominoes, with opponent's item attacks being reflected. Special music (Arranged version of Super Mario Bros.'s invincibility music from Tetris DS) will play when the item is active.
• RANDOM: A random item effect is activated.
• 16t: 16t from Bloxeed. A 16t anvil appears (A reference to Fantasy Zone, a shooting game by Sega), in which the player can move before removing three columns of blocks.
• MISS: (VS) The player's level and item bar will not increase. (Others) Level, score and line count are not affected. (Both) The field shakes every time when the piece is locked.

Bomb Mode

This has been added to the mode backlog, as it was also of interest of the contributors here to add a Bombliss-inspired mode to the set of game modes in this modpack.

Item Blocks

This has already been a subject of potential implementation, especially since NullpoMino's Block class already has an item member defined. However, due to the limitations of the rendering engine that disallows purely visual effects like showing all blocks as [] or the inability to move / rotate the field visually, progress on this has been halted for a long while.

The engine's cycle also makes it difficult to insert item effects for inactive items (e.g. LASER, 16t, 180° FIELD, SHOT GUN, etc.) as the logic for them has to be coded from scratch and inserted into the engine's custom state slot.

Even if it was all sorted, that would only work for one game mode, as one design rule implemented here is that vanilla files that came with the game remain untouched, as to maintain compatibility with other mods that other people create.
