Easily and conveniently resize and rotate blocks (including their block entity renderers and collision boxes) with a single interface.

This is a library mod for Minecraft Forge 1.20.1. Have your Block implement IScalableBlock and/or IRotatableBlock, and it automatically gets scaled/rotated model rendering, BER rendering, and VoxelShape collision, no per-block mixin registration required.

Features

• One interface, everything scaled: implement IScalableBlock, return an SBSProp config, done.
• One interface, everything rotated: implement IRotatableBlock, return an SBSRProp config, and blocks rotate around any axis at any angle.
• Block model rendering: BakedQuad vertices transformed via BakedModel proxy at model bake time, ensuring compatibility with rendering replacers like Embeddium & Oculus.
• Block entity rendering: BERs (chests, signs, etc.) scale and rotate together with their parent block via Mixin injection into BlockEntityRenderDispatcher.
• Collision box scaling & translation: VoxelShape automatically transformed when scaleShape is enabled; intelligently translated to match rotated model center.
• Compound transforms: blocks can implement both interfaces — rotation is applied first, then scaling.
• Configurable pivot: scale and rotate around any anchor point within the block.
• Zero configuration: no mixin config, no JSON, no data-gen. Pure API.

Usage

public class MyBlock extends Block implements IScalableBlock, IRotatableBlock {

@Override
public SBSProp getScaleConfig(BlockState state) {
    // Scale to 50% around the block center, including collision
    return new SBSProp(0.5f, 0.5f, 0.5f, 0.5f, 0.5f, 0.5f, true);
}

@Override
public SBSRProp getRotationConfig(BlockState state) {
    // Rotate 45° around Y axis, centered on the block
    return new SBSRProp(45f, Direction.Axis.Y, 0.5f, 0.5f, 0.5f);
}

@Override
public VoxelShape getShape(BlockState state,
                           BlockGetter level,
                           BlockPos pos,
                           CollisionContext ctx) {
    VoxelShape rotatedShape = getTranslatedShape(state, level, pos, ctx, 
                                                 super.getShape(state, level, pos, ctx));
    return getScaledShape(state, level, pos, ctx, rotatedShape);
}

}

# SBSProp Parameters

| Field | Description |
|-------|-------------|
| `scaleX / Y / Z` | Scale multiplier per axis (1.0 = original) |
| `pivotX / Y / Z` | Anchor point in block coordinates (0~1, 0.5 = center) |
| `scaleShape` | Whether to also scale the collision VoxelShape |

# SBSRProp Parameters

| Field | Description |
|-------|-------------|
| `degree` | Rotation angle in degrees |
| `axis` | Rotation axis (`Direction.Axis.X / Y / Z`) |
| `pivotX / Y / Z` | Anchor point in block coordinates (0~1, 0.5 = center) |

# Compatible
This mod is designed to be compatible with Embeddium & Oculus. Any incompatibility is welcome to feedback.
