Bullet Hell?

[gamecreator]

Here you go Recoils14. I added some comments to hopefully help. Just replace your App.cpp with the following. Also, don't forget that this code uses a bullet.tex and a ship.tex from the Models folder so you'll need those there so the code doesn't crash. It also assumes that the bullet texture is 16x16 and the ship is 128x128, as that is hard coded (but it would be easy to change to detect it).

 

#include "App.h"

using namespace Leadwerks;

#define NUMBEROFBULLETS 1000

App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) {}

App::~App() { delete world; delete window; }

Texture *bullettexture = NULL;
Texture *shiptexture = NULL;

float shipx, shipy;
float fps;

struct bulletinfo
{
  float x, y, vx, vy;
} bullet[NUMBEROFBULLETS];

bool App::Start()
{
  window = Leadwerks::Window::Create("BulletHell", 0, 0, 1728, 972, Leadwerks::Window::Titlebar|Leadwerks::Window::Center);

  context = Context::Create(window);

  world = World::Create();

  camera = Camera::Create();
  camera->Move(0, 2, -5);

  window->HideMouse();

  bullettexture = Texture::Load("Models/bullet.tex");
  shiptexture = Texture::Load("Models/ship.tex");

  //  Generate random bullet position
  for(int i=0; i<NUMBEROFBULLETS; i++)
  {
 bullet[i].x=Math::Random(0, 1700);
 bullet[i].y=Math::Random(0, 950);
 bullet[i].vx=Math::Random(-2, 2);
 bullet[i].vy=Math::Random(-2, 2);
  }

  //  Generate random ship position and velocities
  shipx=Math::Random(0, 1650);
  shipy=Math::Random(0, 900);

  return true;
}

bool App::Loop()
{
  //  Exit program if window is closed or Escape button is hit
  if(window->Closed() || window->KeyHit(Key::Escape))
  {
 printf("\n\nfps: %f\n", fps);
 return false;
  }

  Leadwerks::Time::Update();
  world->Update();
  world->Render();

  //  Move ship with arrow keys
  if(window->KeyDown(Key::Left)) shipx-=Time::GetSpeed()*3.0;
  if(window->KeyDown(Key::Right)) shipx+=Time::GetSpeed()*3.0;
  if(window->KeyDown(Key::Up)) shipy-=Time::GetSpeed()*3.0;
  if(window->KeyDown(Key::Down)) shipy+=Time::GetSpeed()*3.0;

  context->SetBlendMode(Blend::Alpha);


  //  Go through all of the bullets, one by one
  for(int i=0; i<NUMBEROFBULLETS; i++)
  {
 //  If bullet is at the edge of the screen, turn it around
 if(bullet[i].x>1700 && bullet[i].vx>0) bullet[i].vx*=-1;
 if(bullet[i].x<0 && bullet[i].vx<0) bullet[i].vx*=-1;
 if(bullet[i].y>970 && bullet[i].vy>0) bullet[i].vy*=-1;
 if(bullet[i].y<0 && bullet[i].vy<0) bullet[i].vy*=-1;

 //  Move bullet
 bullet[i].x+=bullet[i].vx*Time::GetSpeed();
 bullet[i].y+=bullet[i].vy*Time::GetSpeed();

 //  If bullet is by the ship, turn it blue
 if(bullet[i].x>shipx-8 && bullet[i].x<shipx+136 && bullet[i].y>shipy-8 && bullet[i].y<shipy+136) context->SetColor(0,0,1);
 else context->SetColor(1, 1, 1);

 //  Draw bullet
 context->DrawImage(bullettexture, bullet[i].x, bullet[i].y);
  }

  //  Draw ship
  context->DrawImage(shiptexture, shipx, shipy);

  //  Get frames per second and show it
  fps=Time::UPS();
  context->DrawText("FPS: "+String(fps), 10, 10);

  context->Sync(false);

  return true;
}

Thanks! That's a bit overwhelming for me at this point, but it will give me a good reference so base some of reading off of!

Definitely understandable. It's not complex but it's also not for beginners. Definitely start elsewhere to get a handle on things. Happy to help either way.
