Nibble errors

🎮🕹️🧀Nibble
#1

This is a post for all of my bugs in nibble programming, I will have a lot.

Bug #1:

This code only shows up as a black screen. Is it looping and clearing too fast?

// cm:esp8266:nibble
// cm:esp8266:nibble
#include <Arduino.h>
#include <CircuitOS.h>
#include <Nibble.h>

bool up,down,left,right,a,b,menu;

Display* display;
Sprite* sprite;

//auto colors[] = {TFT_BLACK,TFT_RED,TFT_GREEN,TFT_BLUE,TFT_YELLOW,TFT_CYAN,TFT_MAGENTA,TFT_WHITE};
int icons[] = {

    }
    display->commit();
}

It’s probably a silly error like forgetting a method :woozy_face:

#2

I think you have to display->commit() after each sprite->fillRect()

#3

@Tizzlerbot76 thanks for helping out :slight_smile:
