Patron Shader | 8/6/2020 | Block Pen
Added 2020-08-07 00:22:52 +0000 UTCThis release is a geometry shader that allows you to draw in blocks.
Included is a texture sheet that resembles the Minecraft textures.
This will require a bit of setup, so I'll detail how to get this working on your avatar now:
1) Put the prefab under the root of your hierarchy (it's in the prefab folder!).
2) Right click prefab, unpack.
3) Move "Anchor" to be a child of your hand.
4) Position the "Anchor" somewhere where the blocks are close to your hand, but not really intersecting with your hand. Don't worry if they're centered or not - they likely wont be!
All of the preview stuff should be following this anchor!
5) Create a gesture that enables the "BlockSpawnController" object. This will enable a particle system that places a single particle instantly, which in this case, will turn into a block.
6) Build stuff!
It's pretty simple to get it set up, and easy to customize!
To use it and swap which blocks, just move your hand around and position the small preview block within the grid cells segments. This will change which block will be placed.
I will be updating this system later with an Avatars 3.0 setup that will allow you to select more block types from the Avatars 3.0 menu.
As with last time, the shader is full of comments within the "MCGEO.cginc" file, explaining my thought process and how things are working. Feel free to ask any questions on discord, the comments, or otherwise!
