AABBIntersectionTest: Open in GitHub

AngleConstraint: Open in GitHub

Ascii85: Converts between binary data and an Ascii85-encoded string. Open in GitHub

BlockFacing: Represents one of the 6 faces of a cube and all it's properties. Uses a right Handed Coordinate System. See also http://www.matrix44.net/cms/notes/opengl-3d-graphics/coordinate-systems-in-opengl In short: North: Negative Z East: Positive X South: Positive Z West: Negative X Up: Positive Y Down: Negative Y Open in GitHub

BlockPos: A useful data structure when operating with block postions.
Valuable Hint: Make use of Copy() or the XXXCopy() variants where needed. A common pitfall is writing code like: BlockPos abovePos = pos.Up(); - with this code abovePos and pos will reference to the same object! Open in GitHub

CachingCollisionTester: Originally intended to be a special version of CollisionTester for BehaviorControlledPhysics, which does not re-do the WalkBlocks() call and re-generate the CollisionBoxList more than once in the same entity tick
Currently in 1.20 the caching is not very useful when we loop through all entities sequentially - but empirical testing shows it is actually faster not to cache Open in GitHub

Mat22: 2x2 Matrix Open in GitHub

Mat23

2x3 Matrix

A mat2d contains six elements defined as:
[a, b,
c, d,
tx,ty]
This is a short form for the 3x3 matrix:
[a, b, 0
c, d, 0
tx,ty,1]
The last column is ignored so the array is shorter and operations are faster. Open in GitHub

Mat4d: 4x4 Matrix Math Open in GitHub

Mat4f: 4x4 Matrix Math Open in GitHub

MultiCollisionTester: Open in GitHub

NatFloat: A more natural random number generator (nature usually doesn't grow by the exact same numbers nor does it completely randomly) Open in GitHub

NewNormalizedSimplexFractalNoise: Open in GitHub

NewSimplexNoiseLayer: Open in GitHub

NormalRandom: Open in GitHub

NormalizedSimplexNoise

It's generally pretty hard to get a neatly normalized coherent noise function due to the way perlin/open simplex works (gauss curve) and how random numbers are generated. So instead of trying to find the perfect normalization factor and instead try to perform some approximate normalization this class allows a small overflow and brings it down very close to the [0, 1] range using tanh().

Returns values in a range of [0..1] Open in GitHub
