Description

This variable is incremented each time gb.update() is called, so it represents the number of frames rendered since the program began running. It should be preferred over millis() to measure time. It can be used for periodic event timing (like an animated bitmap) using modulo.

Syntax

int count = gb.frameCount;

Parameters

none

Returns

Number of frames rendered since the program began running (unsigned long).

Example

#include <SPI.h>
#include <Gamebuino.h>
Gamebuino gb;

void setup(){
  gb.begin(F("Example game"));
}

void loop(){
  if(gb.update()){

    int count = gb.frameCount;
    gb.display.println(count);

    if((count%5) < 2){ //true for 2 frames once every 5 frames
      gb.display.println(F("BLINK"));
    }

  }
}
