Pre Alpha 1.2 Release Checklist - The Shape & Data Update

[lucasdamianjohnson]

• [x] Fix the issue with textures not actually being aligned correctly. Might have to switch the UV or change the face.
• [x] Make a way for different voxel shapes to cull faces. For instance, have a half-box call its bottom face only if it is directly on top of a box.
• [x] Fix the problem with the voxel state data not being properly set and passed.
• [x] Upgrade the ShapeBuilder to have more options and transform vectors for creating many different types of shapes.
• [x] Add a "Face state" vertex data attribute for all meshes to control shaders. For instance, if a fluid meshes face is flipped that state should be set and the texture should be set to flow in the correct direction.
• [x] Also, correct the flora shader to create the "wind" effect only if the proper face state is set. Also have different modes for something like leaves vs vines and so on.
• [x] Add "tile entities" or a way to connect voxels to "rich data"
  • Will need to create a new type of region just for rich states.
• [X] Add cull face and AO overrides for shapes
• [x] Fix the AO by checking to flip the states.
• [x] Add a 360 rotation so that textures can be flipped.
• [x] Add new types of shapes.
  • [X] Vines aka Panel
  • [x] Stairs
    • [x] Bottom states
    • [x] Top States
    • [x] Connected Bottom States
    • [x] Connected Top States
• [x] Add a way to generate a chunk in the constructor thread so chunks and generated in parallel.
• [x] Implement the shape state data.
• [x] Add a way to flip a texture. Must account for when the texture is flipped.
• [x] Implement a helper UV function to generate the correct UV data.
• [x] Add an overlay texture mode and add it to the chunk templates and the generated mesh data.
• [x] I will have to make an overlay texture for each mesh type.
• [x] Remove "per-region voxel palettes".
• [x] Add an easy way to create a custom voxel manager to pass to WorldMatrix.
• [x] Implement an optional physics property for voxels.
• [x] Create a way to save a region and a way to load in a region.

Changes

---

List of things that I will need to update the wiki for. Will also have to update the wiki for 1.1.

Voxel Data Change

So, I changed the voxel data type definition. It is now:

type VoxelData = {
    name: string;
    shapeId: string;
    id: string;
    substance: VoxelSubstanceType;
    physics?: {
    boundingBoxId: string;
    checkCollisions: boolean;
    };
    states?: string[];
    lightSource?: boolean;
    lightValue?: number;
};

This is a breaking change from other versions. But now voxel states actually work. So, when you add a state to the states array it will be passed to the voxel process function so you can do different things with it.

Also realized that the defaultState literally did nothing so I just removed it.

Voxel Process Data Change:

The voxel process data has changed.

export type VoxelProcessData = {
 exposedFaces: number[];
 faceStates: number[];
 textureRotations: Rotations[];
 voxelData: number;
 voxelState: string;
 voxelShapeState : number;
 uvTemplate: number[];
 overlayUVTemplate: number[];
 colorTemplate: number[];
 lightTemplate: number[];
 aoTemplate: number[];
 chunkX: number;
 chunkY: number;
 chunkZ: number;
 x: number;
 y: number;
 z: number;
};

World Data Changes:

paintVoxel is now:

 paintVoxel(
  voxelId: string,
  voxelStateId: string,
  shapeState : number,
  x: number,
  y: number,
  z: number
 ) {
}

And requestVoxelAdd is now:

 async requestVoxelAdd(
  voxelId: string,
  voxelStateId: string,
  shapeState : number,
  x: number,
  y: number,
  z: number
 ) {
}

Added a shape state param to each.

Changes:

• Changed VoxelData type.
• Removed onReady from initData for DVEC, DVEW, DVEM, and DVED.
• Added a paraemter for the getData function for both WorldData and WorldMatrx for getting voxel state data.
• Added a function getVoxelShapeState to WorldMatrix.
• Changed WorldData getVoxel function to return the voxel shape state id as the third item in the array.
• For the voxel process function the voxelShapeStateTemplate was replaced with voxelShapeState which is just the number. So, you can't change it in the voxel process function.
• Voxels constructor objects no longer have to push their shape id onto an array. It is done automatically.

Name changes:

• Renamed VoxelBuilderThreadObject to VoxelConstructorObject.
