Add the Shapes system

[Hugman76]

This PR adds the concept of shapes and implements this system to Minecraft. This system brings easy creation and management for 2D and 3D geometrical shapes in the Minecraft environment by mainly using Mojang's new Codec technology. We also use the Terraformer's shapes API for constructing precise abstract shapes and for placing them in the world.

Shapes

• [x] Shapes/shape processors are defined by a shape/shape processor type and its corresponding arguments (eg. width & height for rectangles, radii for ellipses)
• [x] Shape types are managed in a registry (mods can add to it)

• type | ID of shape type
• type fields (see below)

Shape Types

• [x] dawn:empty

  no fields

• [x] dawn:rectangle

• width | float provider
• height | float provider

• [x] dawn:rectangular_prism

• width | float provider
• height | float provider
• depth | float provider

• [x] dawn:rectangular_pyramid

• width | float provider
• height | float provider, cannot contain zero
• depth | float provider

• [x] dawn:ellipse

• a | float provider, cannot contain zero
• b | float provider, cannot contain zero

• [x] dawn:elliptical_prism

• a | float provider, cannot contain zero
• b | float provider, cannot contain zero
• height | float provider

• [x] dawn:elliptical_pyramid

• a | float provider, cannot contain zero
• b | float provider, cannot contain zero
• height | float provider, cannot contain zero

• [x] dawn:triangular_prism

• width | float provider
• height | float provider, cannot contain zero
• depth | float provider

• [x] dawn:ellipsoid

• a | float provider, cannot contain zero
• b | float provider, cannot contain zero
• c | float provider, cannot contain zero

• [x] dawn:hemi_ellipsoid

• a | float provider, cannot contain zero
• b | float provider, cannot contain zero
• c | float provider, cannot contain zero

• [ ] dawn:custom

• equation | equation
• variables | list of float providers?

Shape Processor

• [x] All fields are providers, which means you can provide custom int and float providers for shape sizes (eg. make an height oscillate randomly between 3 and 4) but can also be parsed as literal
• [x] Shape processor types are managed in a registry (mods can add to it)

• processor | ID of shape processor type
• type fields (see below)

Shape Processor Types

• [x] dawn:add

• shape | configured shape, ID reference or inline

• [x] dawn:subtract

• shape | configured shape, ID reference or inline

• [x] dawn:exclude

• shape | configured shape, ID reference or inline

• [x] dawn:intersect

• shape | configured shape, ID reference or inline

• [x] dawn:translate

• x | float provider, 0.0 by default
• y | float provider, 0.0 by default
• z | float provider, 0.0 by default

• [x] dawn:rotate

• x | float provider, 0.0 by default
• y | float provider, 0.0 by default
• z | float provider, 0.0 by default
• degrees | boolean, true by default

• [x] dawn:scale

• x | float provider, 1.0 by default
• y | float provider, 1.0 by default
• z | float provider, 1.0 by default

• [x] dawn:noise_translate

• magnitude | float provider, 1.0 by default
• seed | long, randomized by default

Configured Shapes

• Configured shapes can be defined in two manners:
  • [x] A shape field and a configured shape processor list field
  • [x] A shape object itself
• [x] Configured shapes are managed by a reloadable registry that retrieves data from data/<mod_id>/configured_shapes

• shape | shape
• processors | list of shape processors, can be empty but must be present

  
  OR a plain, inline shape object

Configured Shape Processors

• Configured shape processors can be defined in two manners:
  • [x] A shape processor field and the number of times the processor will get applied
  • [x] A shape processor object itself

• processor | shape processor
• repeat | int provider, must be positive

  
  OR a plain, inline shape processor object

Extra content

Feature

• [x] New feature type: dawn:shape, so that shapes can be used within configured features

• shape | configured shape, ID reference or inline
• state | block state provider
• y_offset | float provider, 0.0 by default

Foliage Placer Type

• [ ] New foliage placer type: dawn:shape, so that shapes can be used as foliage for trees

Command

• [x] The /shape command can place shapes filled with a specified block Syntax : /shape <configured shape> <pos> (fill) <block>
