Don't repeat the animation after reaching the end of the segment? about fastfx HOT 8 OPEN

Hi - I think the simplest way to do what you are looking for would be to override the onCycleEnd method: class FirstLightFX : public FFXBase { public: FirstLightFX(uint16_t initSize) : FFXBase( initSize,/* interval */ 15UL, /* min interval */ 15UL, /* max interval */ 30UL ) { getFXColor().setColorMode( FFXColor::FFXColorMode::singleCRGB ); getFXColor().setCRGB( CRGB::White ); } virtual void initLeds( CRGB *bufLeds ) override { fill_solid( bufLeds, numLeds, CRGB::Black ); } virtual void onCycleEnd( CRGB *currFrame ) override { endAnimation = true; } virtual void writeNextFrame( CRGB *bufLeds ) override { Serial.print("CYCLE: "); Serial.println(getCurrCycle()); Serial.print("PHASE: "); Serial.println(getMovementPhase()); fadeToBlackBy( bufLeds, numLeds, 25 ); if(!endAnimation) { bufLeds[getMovementPhase() - 1] = currColor.getCRGB(); } // if (getMovementPhase() > numLeds) { // endAnimation = true; // } } }; Let me know if you have any issues and I can help you get the desired behavior.

Yes - Just move your variable to inside the effect class. That way it will only affect the segment in question - as follows: class FirstLightFX : public FFXBase { private: bool endAnimation = false; public: void setEndAnimation( bool newValue ) { endAnimation = newValue; } bool getEndAnimation() { return endAnimation; } FirstLightFX(uint16_t initSize) : FFXBase( initSize,/* interval */ 15UL, /* min interval */ 15UL, /* max interval */ 30UL ) { getFXColor().setColorMode( FFXColor::FFXColorMode::singleCRGB ); getFXColor().setCRGB( CRGB::White ); } virtual void initLeds( CRGB *bufLeds ) override { fill_solid( bufLeds, numLeds, CRGB::Black ); } virtual void onCycleEnd( CRGB *currFrame ) override { endAnimation = true; } virtual void writeNextFrame( CRGB *bufLeds ) override { Serial.print("CYCLE: "); Serial.println(getCurrCycle()); Serial.print("PHASE: "); Serial.println(getMovementPhase()); fadeToBlackBy( bufLeds, numLeds, 25 ); if(!endAnimation) { bufLeds[getMovementPhase() - 1] = currColor.getCRGB(); } } }; Note that if you want to check or reset the endAnimation on any individual segment, you need to cast that segment's FX object to your effect type, so you would use something like: (FirstLightFX)(seg->getFX())->setEndAnimation(false); FWIW - For what you are looking to accomplish, it may make more sense to use the OverlayFX class, which is intended to only run through a single cycle. There’s not an example that does exactly the same thing, but the ZipOverlayFX class would be close. The advantage to doing this is that you can have another color or effect in the background, and the overlay effect is “run” over the top of this and then disposed when it completes. You would do something like this: FFXOverlay *newOvl; // do this for each segment, each time you want to run a “one-shot” animation - newOvl = new ZipOverlayFX( seg->getLength(), 255, 1); // speed: 255, cycles: 1 newOvl -> setPalette( NamedPalettes::getInstance()[“white_wave_gp”]; newOvl -> setMovement( FFXBase::MovementType::MVT_FORWARD ); newOvl -> setAlpha(255); // opacity - 255 is max seg->setOverlay(newOvl); Geoff Moehrke ***@***.***

The findSegment() function takes a String reference as a parameter - I’m not sure how you are calling it, but if you’re using a constant, you should be able to just create an inline String by doing: ctrler->findSegment( String(MY_CONST) ); Geoff Moehrke ***@***.***
