Hey, I am making a shooting game and I want to score a point each time I shoot an enemy. It's kind of urgent, Can anybody help me please?
Here's the code:
//import gif
import gifAnimation.*;
Gif myAnimation;
int recX = width/2;
int recY = height/2;
int skip=2;
int j=0;
int playerHealth=100;
int playerWidth = 55;
int playerHeight = 65;
int playerLives=5;
float posX;
boolean playerAlive=true;
boolean createShips=false;
float time=60;
int level=1;
int wallGap = 50;
Ship[] ships;
Laser[] lasers;
PFont font; //import font
PImage space;//import background
PImage enemy;//import enemy
PImage player;//import spaceship
PImage explosion;//import explosion gif
void setup()
{
size(800, 600);//background
noStroke();//images without stroke
font = loadFont("AddElectricCity-48.vlw");//load font
//load images
player=loadImage("space.png");
enemy=loadImage("enemy.png");
space = loadImage("space.jpg");
Gif Animation = new Gif(this, "explosion1.gif");
myAnimation=Animation;
myAnimation.noLoop();
createEnemies(1);//refresh ships
lasers=new Laser[5000];//refresh lasers
}
void draw()
{
image(space,0,0,width,height);
textFont(font, 18);
fill(255);
text("Level "+level+" ", 10, 30);
text("Lives:"+playerLives, width-120, 30);
if(playerLives<=0)
{
textFont(font, 60);
fill(255,0,0);
text("GAME OVER", width/2-200, height/2);
}
if(level==5)
{
textFont(font, 30);
fill(0, 150, 0);
text("Congratulations !!", 200, height/2);
text("You WIN !", width/2-100, height/2+50);
}
