STARCRAFT — Alpha 0.15.4

========================

ALPHA 0.15.4 — STRONGHOLD MAZES AND TRIAL CHAMBERS

- Rebuilt Overworld strongholds as large underground mazes (11x11 room network) with deterministic seed-based layouts.

- Each generated stronghold has a randomized portal-room location inside the maze and a complete, already-active 3x3 End Portal surrounded by 12 End Portal Frame blocks.

- Added underground Trial Chambers at a 1.2% candidate rate per eligible Overworld chunk, with a large 13x13-room copper maze.

- Added 20 Trial Chambers construction blocks: Copper Grate, Exposed Copper Grate, Weathered Copper Grate, Oxidized Copper Grate; Copper Bulb and its three oxidation states; Chiseled Copper and its three oxidation states; Copper Bricks and its three oxidation states; Copper Tiles and its three oxidation states.

- Added functional Trial Spawners. Right-click to spawn a six-mob wave. Defeat the wave to receive a Trial Key.

- Added functional Vaults. Hold a Trial Key and right-click a Vault to consume the key and receive randomized treasure. Each Vault pays out once, and its opened state is saved.

- Added underground World.getBiomeAt() recognition for the trial_chambers biome.

- Added custom copper textures and expanded the atlas to 256x512 (16 columns by 32 rows) so the new textures do not exceed the former 16x16 atlas.

- Existing block and custom-item IDs were preserved by appending new blocks and the Trial Key. Previous 320-block build height, biome updates, camps, embedded crowned-pig background, inventory fix, Nether mob-spawn crash fix, and three STARCRAFT community-server entries are retained.

CONTROLS

- Use the normal right-click / place action while aiming at a Trial Spawner to begin the challenge.

- Defeat the spawned mobs to receive a Trial Key.

- Put the Trial Key in your selected hotbar slot, aim at a Vault, and right-click to open it.

- To enter the End, walk into the active End Portal in a stronghold.

TESTING

- Strongholds and Trial Chambers are deterministic per seed/chunk and can be skipped by terrain/world-generation suitability conditions.

- Use a new world for the quickest test, or travel to previously ungenerated Overworld chunks in an existing world. Previously generated chunks are not automatically regenerated.

- Syntax and ZIP integrity checks passed. Full live 3D gameplay, mob AI pathing through every maze branch, and an actual portal/Vault playthrough were not verified in a live browser during packaging.

Version: Alpha 0.11.2
Date: 2026-10-15
Credit: STARCRAFT Water Physics, Breath, and 3D Player View Update
Changes:

• Fixed: Fall damage is prevented if the player enters water during a fall, including when they later reach the seabed

• Added: Water buoyancy that gently carries players toward the surface, with jump to swim upward and Left Control to dive

• Updated: Ocean, coral reef, and kelp forest floors generate an 8-block sand layer above stone/deepslate

Version: Alpha 0.10.3
Date: 2026-10-15
Credit: STARCRAFT Chunk Seam and Crouch Update
Changes:

• Fixed: Neighboring chunk meshes are rebuilt when adjacent terrain becomes available, reducing visible gaps and unculled seam faces

• Added: Hold Left Control to crouch/sneak; crouching lowers the player collision height, reduces movement speed, and preserves edge-sneaking protection

Version: Alpha 0.10.2
Date: 2026-10-15
Credit: STARCRAFT Safe Spawn, Structures, and Wildlife Update

• Added: Pandas in jungles, goats in mountain biomes, and endermen that become hostile only after the player looks at their eyes

• Updated: Changelog records the Alpha 0.10.2 world-generation and wildlife fixes

Version: Alpha 0.10.1
Date: 2026-10-15
Credit: STARCRAFT Terrain, Structures, and Wildlife Update

• Added: Mountain biomes with snowy high-elevation peaks

• Added: Jungle biome with taller jungle trees, jungle leaves, bamboo plants, and jungle blocks

• Added: Panda mobs that spawn in jungles and goat mobs that spawn in mountains and snowy spruce areas

Changes:

Date: 2020-08-28
Credit: Willard
