[13:49][Determine to work on asset binding, using Snuffleupagus-Oriented Programming][:"asset system" :"entity system" :"procedural generation" :speech]
[17:45][Snuffleupagus-Oriented Programming (SOP)][:speech]
[19:42][Set up to bind assets to entities][:"asset system" :"entity system" :"procedural generation" :speech]
[24:59][Change the multi-dimensional version of AddPiece() to take a v3 Dim][:"entity system" :"procedural generation"]
[30:25][:Run the game to see that all is well and good][:"entity system" :"procedural generation"]
[32:19][Introduce EncodeCubeUVLayout()][:"asset system" :"entity system"]
[46:26][Consider the visibility of our :art, with an eye to the possible future existence of floor tiles that reflect the undersides of tiles above them][:"asset system" :"entity system" :run]
[49:21][Make EncodeCubeUVLayout() encode the BottomIndex and BottomFacingIndex in the final two bits of our UV layout, and PushCube() decode UV layouts][:"asset system" :"entity system"]
[1:04:38][Enable PushCube() to directly decrypt coordinates without a table lookup][:"asset system" :"entity system" :mathematics]
[1:13:58][Switch the Renderer Test over to use our new UV layout][:"asset system" :"entity system"]

[1:31:28][Consider supporting mirroring][:"asset system" :"entity system" :speech]
[1:33:12][Move on to asset tagging, possibly using a two-tier system: 1) select asset set; 2) use entity information to pick asset from set][:"asset system" :"entity system" :speech]
[1:41:20][Introduce the notion of an asset_basic_category][:"asset system" :"entity system"]

[1:53:23][Q&A][:speech]
[1:53:51][@Rounin][Q: In the Renderer Test, the corner blocks that are on the side of the building have their diagonal beams reversed, due to sharing their texture with the front blocks. Do you have a plan for handling that?][:"asset system" :"entity system"]
