My code only runs once ? It seems to get stuck in a function, not allowing my car to move after the first click

void loop() {
  float d = 0.3;
  float s = 0.42;

  while (IrReceiver.decode() == 0) {}

  if (IrReceiver.decodedIRData.command == 0x46) {
    Serial.println("forward");
    car.forward(d, s);
  }
  if (IrReceiver.decodedIRData.command == 0x15) {
    Serial.println("backward");
    car.backward(0.3, 0.42);
  }
  if (IrReceiver.decodedIRData.command == 0x43) {
    Serial.println("right");
    car.right(90);
  }
  if (IrReceiver.decodedIRData.command == 0x44) {
    Serial.println("left");
    car.left(90);
  }
  IrReceiver.resume();
}

So this code reads from the IR, hangs in a loop if nothing is received and then does the moves based on the command code?

If so it might be better to use a switch case here...

Something along the lines of:

void loop() {
  float d = 0.3;
  float s = 0.42;

  if (IrReceiver.decode() != 0) {
    switch (IrReceiver.decodedIRData.command) {
      case 0x46:
        Serial.println("forward");
        car.forward(d, s);
        break;
      case 0x15:
        Serial.println("backward");
        car.backward(0.3, 0.42);
        break;
      case 0x43:
        Serial.println("right");
        car.right(90);
        break;
      case 0x44:
        Serial.println("left");
        car.left(90);
        break;
      
      default:
        break;
    }
    IrReceiver.resume();
  }
}
