I’m having this code reading data from sd card and send to leds only the buttons are not working because it first handles the whole while loop from sd card, how to fix this anyone?
if(button4.fell()){
if (AutoState == 0){
AutoState = 1;
} else if (AutoState == 1){
AutoState = 0;
}
}

fxdata = SD.open(“pakje723.dat”); // read only
if (fxdata)
{
Serial.println(“file open ok”);
}

while (fxdata.available())
{
/for (int i=0; i < NUM_LEDS_total; i++) {
tmp[i].r = fxdata.read();
tmp[i].g = fxdata.read();
tmp[i].b = fxdata.read();
}/
fxdata.readBytes((char*)tmp, NUM_LEDS_total * 3);

for (int i=0; i < NUM_LEDS_total; i++) {
  //leds[i] = tmp[i];
  colourStore[XYTable[i]] = tmp[i];
}


//Left Arm
for(int x=0;x<73;x++) {
  leftArmTop[x]= colourStore[leftArmTopArray[x]]; 
}

for(int x=0;x<70;x++) {
  leftArmBottom[x]= colourStore[leftArmBottomArray[x]]; 
}

//Right Arm
for(int x=0;x<73;x++) {
  rightArmTop[x]= colourStore[rightArmTopArray[x]]; 
}

for(int x=0;x<70;x++) {
  rightArmBottom[x]= colourStore[rightArmBottomArray[x]]; 
}

//Chest  
for(int x=0;x<355;x++) {
  chestMain[x]= colourStore[chestMainArray[x]];
}
for(int x=0;x<70;x++) {
  chestLeft[x]= colourStore[chestLeftArray[x]]; 
}
for(int x=0;x<80;x++) {
  chestMiddle[x]= colourStore[chestMiddleArray[x]]; 
}
for(int x=0;x<70;x++) {
  chestRight[x]= colourStore[chestRightArray[x]]; 
}

FastLED.setBrightness(brightnessCounter);
FastLED.show();
FastLED.delay(25);

}
fxdata.close();

You might look into using interrupts to detect your button presses.

how about:

while ((fxdata.available()&&(!(button4.fell()))))

assuming you want to drop out of the while loop on a button press

I’m assuming that your loop will run many times faster than you can physically press and release a button, so don’t worry about checking the button only once per loop

or just read your button somewhere within your wile loop - say once a frame, so you could put it right by your FastLED.show()
