I wanted to make the enemy follow the player. I run the code on my makerbuino it just froze.
Here is that code:

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

//player variables
int player_h = 4;
int player_w = 4;
int player_x = (LCDWIDTH - player_w)/2;
int player_y = (LCDHEIGHT - player_h)/2;
int player_vy = 2;
//enemy variables
int enemy_h =6;
int enemy_w =6;
int enemy_x =(LCDWIDTH - enemy_w)/2;
int enemy_y =(LCDHEIGHT - enemy_h)/2;
int number_1 = 1;
//functions
int DistanceAddX(int enemy_x,int number_1) 
{ 
    int result;

    result = enemy_x + number_1;
    gb.display.fillRect(enemy_x, enemy_y, enemy_w, enemy_h);

 
    return result;
} 

int DistanceRemoveX(int enemy_x,int number_1) 
{ 
    int result;

    result = enemy_x - number_1;
    gb.display.fillRect(enemy_x, enemy_y, enemy_w, enemy_h);

 
    return result;
} 

int DistanceAddY(int enemy_y,int number_1) 
{ 
    int result;

    result = enemy_y + number_1;
    gb.display.fillRect(enemy_x, enemy_y, enemy_w, enemy_h);

 
    return result;
} 

int DistanceRemoveY(int enemy_y,int number_1) 
{ 
    int result;

    result = enemy_y - number_1; 
    gb.display.fillRect(enemy_x, enemy_y, enemy_w, enemy_h);


    return result;
} 
void setup() {
  // put your setup code here, to run once:
  gb.begin();
  gb.titleScreen(F("Knight's walk"));
  gb.pickRandomSeed();
  gb.battery.show = false;
  gb.display.fontSize = 2;
}

void loop() {
  // put your main code here, to run repeatedly:
  
    if(player_x > enemy_x)
    {
      
    return DistanceAddX;
    
    } 
    else if(player_x < enemy_x)
    {
      
    return DistanceRemoveX;
    
    }          
    
      if(player_y > enemy_y)
      {
      
      return DistanceAddY;
    
      } 
      else if(player_y < enemy_y)
      {
      
      return DistanceRemoveY;
        
      }
      
  if(gb.update()){

    if(gb.buttons.repeat(BTN_UP, 1)){
      player_y = max(0, player_y - player_vy);
    }
    if(gb.buttons.repeat(BTN_DOWN, 1)){
      player_y = min(LCDHEIGHT - player_h, player_y + player_vy);
    }
    if(gb.buttons.repeat(BTN_LEFT, 1)){
      player_x = max(0, player_x - player_vy);
    }
    if(gb.buttons.repeat(BTN_RIGHT, 1)){
      player_x = min(LCDWIDTH - player_w, player_x + player_vy);
    }
    gb.display.fillRect(player_x, player_y, player_w, player_h);

   
    }
  }
