11018-11033: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winPer-pixel
sin_tloop costs up to 15 float sine calls per LED per frame.For each pixel the inner loop runs
wavesiterations, and each iteration callssin_t(phase)with float math. On a long strip, such as 300 LEDs, this means about 4500 calls per frame. This is slow on ESP8266 and on RISC-V targets without an FPU. The effect is not in a pixel set/get hot path, so this is not a rule violation.Precompute these per-frame values outside the pixel loop:
twoPi * LIQ_FREQ[k] * t + LIQ_PHI[k]twoPi * LIQ_CYCLES[k] * cscale * LIQ_DIR[k] / lenKeep the inner loop to one multiply-add and one sine. Alternatively, use the fixed-point
sin16_t.🤖 Prompt for AI Agents

Learning: In WLED effect/overlay implementations (C++ under wled00), ensure effects operate through the SEGMENT.* read/write APIs for their own pixels/overlay state. Reserve global frame reads/writes like strip.getPixelColor* for copy_* style post-processing only. Do not manually composite/blend across lower layers inside the effect; segment-to-segment blending is handled later by WS2812FX::blendSegment(), so effects should produce their per-segment contributions without trying to composite with underlying layers themselves.

you don't need to add const to all variables that are only computed once. It does not make a difference for the compiler (=not any faster). That's why in this repo, we prefer to not use const unless it really makes a difference.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Make the sixteenth wave selectable.
When SEGMENT.intensity is 255, integer division sets waves to 15. The effect never uses table entry 15, although its description promises up to 16 waves. Adjust the mapping so 0 remains off and 255 selects 16 waves. As per path instructions, “VERIFY numerical stability / accuracy of arithmetic expressions.”

Preserve the RGBW white channel.
If a selected color uses only its white channel, these expressions extract zero for every channel. The Liquid effect then renders that color as black, including on RGBW strips. Extract and blend the white channel with RGB, then pass all four channels to SEGMENT.setPixelColor.

@softhack007 SEGCOLOR(x) returns four 8-bit color components, packed into a uint32_t as 0xWWRRGGBB:
| Bits | Component | Extraction |
|---|---|---|
| 31–24 | White | W(SEGCOLOR(x)) |
| 23–16 | Red | R(SEGCOLOR(x)) |
| 15–8 | Green | G(SEGCOLOR(x)) |
| 7–0 | Blue | B(SEGCOLOR(x)) |
In wled00/FX.h, the macro calls Segment::getCurrentColor(x). The packing and extraction macros are defined in wled00/colors.h.
NUM_COLORS == 3 means three color slots per segment, not three components per color.
The Liquid code extracts only RGB. It therefore discards the white component. A white-only color such as 0xFF000000 produces zero for all three extracted channels.

The remaining fields also match:
;!,!,!;exposes all three color controls used by the effect.- The empty palette field hides the palette control. The effect does not use palettes.
- The empty capability field defaults to
1in the UI, which identifies a 1-D effect. - The defaults appear after the final semicolon, as required by
extractModeDefaults().
Two code comments do not match the implementation:
- The effect supports at most 15 waves, not 16:
255 / 16 == 15. - Shimmer Width reaches 0.30, not 0.20, at slider value 31.
Optionally, make the 1-D flag explicit and label the color controls by role:
static const char _data_FX_MODE_LIQUID[] PROGMEM =
"Liquid@Speed,Waves,Wavelength,Shimmer Height,Shimmer Width;Primary,Secondary,Shimmer;;1;sx=128,ix=128,c1=128,c2=227,c3=10";This is a clarity improvement, not a required metadata fix.

Added a new effect called "Liquid", which is an addition of up to 16 sine waves of different wave lengths, frequencies, directions and offsets. Each wave is one of the first 2 colors. The third color is used for a 'shimmer' effect: when the wave is around a certain height, the shimmer color is blended in. The effect adds a good water/lava simulation I could not manage with existing effects.
The effect parameters and calculations are described in more detail in the code comments.
Tested:
✅ Code compiles (esp32dev)
✅ Effect works as intended
✅ Did not break anything
✅ Tested on ESP32 + SK8612/WS2814 RGBW
