Shader Redstone 3 MANUAL (2019-11-28)

Changes from Shader Redstone 2:

• Improved UI (WIP).
• Full 3D world to edit.
• AA, AO, Vignette and more effects.
• Instant energy propagation through Redstone dust (like Minecraft, allows for accurate clocks).
• Player movement.

Notes:

• Currently Buffer A Can't compile on Windows because ANGLE's DirectX 9 backend (Used by default on Chrome and Firefox on Windows) doesn't fully implement WebGL 2. It tries to force unroll loops which are impossible to unroll in the pathfinding function.
• Cannot power a stone block using Redstone dust yet except if it's under it, and that's an extra update.
• This was partly inspired by Javascript Redstone Simulator.
• I used RNG code from Hash Without Sine 2 (WebGL 2).
• I used a SDF font code for the UI from Shadertext Proportional Spacing.

Rules:

• Anything which is bright red is lit and anything which is dark red is unlit.
• Torches are lit by default.
• Dust is unlit by default.
• Energy from torches spreads through dust (OR operator).
• If a stone block is powered, any torch attached to the block will be off (NOT operator).

Default Controls:

• You can move around in the XY plane using WASD by default.
• You can zoom up or down using Q and E by default.
• You can move quicker using LSHIFT.
• You can place blocks using F, and remove using R.
• You can switch selected item using LEFT and RIGHT (arrows).
• You can change Z layer using DOWN and UP (arrows).

Creating Basic Logic Gates:

The OR gate:

The NOT gate (unary):

The AND gate:

Output should be true only when both inputs are true.

The XOR gate:

Output should be true only when either A or B is set to true.
