General / Drawing lots of shapes

Do you know of any examples I can check out?

Is it at all possible that the object instantiated in Projectile() goes out of scope and the pointer is left pointing to nothing?

Here you go:

Code: [Select]





class Entity{


public:
sf::Sprite mySprite;
sf::Image *myImage;
std::vector<sf::IntRect> &frames;
sf::RenderWindow &myApp;
Vector2 dir;
float speed;

public:
Entity(sf::RenderWindow &app, sf::Image &myImage, std::vector<sf::IntRect> &framesVec, float x, float y, float dirx = 0.0f, float diry = 0.0f)
: myApp(app), frames(framesVec), myImage(&myImage)
{
dir.setXY(dirx,diry);

mySprite.SetImage(myImage);

mySprite.SetPosition(x,y);    

}

void update(float delta){

}




void draw(){
myApp.Draw(mySprite);
}


};


std::vector<Projectile*> entities;

void AddEntity(Projectile *ent){
entities.push_back(ent);
}

class Projectile: public Entity{
public:
Direction direction;
Animator myAnimator;

Projectile(sf::RenderWindow &app, sf::Image *myImage, std::vector<sf::IntRect> &framesVec, float x, float y, Direction DIR)
: Entity(app, *myImage, framesVec, x,  y)  {

speed = 10.0f;

if (DIR == RIGHT)
dir.setXY(speed,0);
else
dir.setXY(-speed,0);

myAnimator.AddNewSequence("start", 0, 0);
myAnimator.AddNewSequence("fly", 1, 3);

myAnimator.PlayAnimation("start","fly");
mySprite.SetSubRect(frames[myAnimator.UpdateAndGetFrame(.0001)]);
AddEntity(this);
}

...


class Character: public Entity{
public:

bool moving;
Direction direction;
const float speed;
const float jumpSpeed;

bool shooting;
bool falling;
bool jumping;
int jumpStartHeight;
int fallStartHeight;
int maxJumpHeight;

Animator myAnimator;

Character(sf::RenderWindow &app, sf::Image &myImage, std::vector<sf::IntRect> &framesVec, float x, float y, float dirx = 0.0f, float diry = 0.0f)
: Entity(app, myImage, framesVec, x,  y,  dirx, diry,  maskr,  maskg,  maskb), speed(120.0f), jumpSpeed(370.0f), maxJumpHeight(140)

...

Character::Shoot(){
Projectile FIRE(myApp, myImage, LoadProjectileFrames(), mySprite.GetPosition().x, mySprite.GetPosition().y, direction);

}

When the new Projectile's Draw() is called, it stops, throws the above error, and doesn't remember anything about the Entity. I am sure the problem is something stupid, but I can't seem to find the problem.

How do you cycle through your objects and draw/update them in a typical program? I am currently using a std::vector of pointers to Entity objects(a class I wrote) that each have a Draw() and Update() function. However, when I initialize a "bullet" for my game and pass in a reference to the App, the image it will use, and some information regarding its location and animation and then add it to the vector using push_back(*this) (I don't have the code in front of me, so I don't know if I actually used an asterisk there). However, on the first iteration after it is added and Entity.Draw() is called, it throws an error(something about  an "unhandled exception at 0x01290f71"). When I investigated this using the debugger, I found that the object is completely "naked" i.e. none of its variables have been initialized/saved from when the object was created.

General / SFML Installation issue

I don't know what that is, so no?

I am sure that everything is working correctly now, but for some reason, when I run the code, my compter slows to a crawl(20% +) CPU usage, and my physical machine makes a high pitched noise. Interestingly, it only makes this noise when the window is in the foreground(when I cover it up, noise stops). The actual window appears to be unresponsive, but I can close the cmd and it closes the whole thing.

General / SFML Installation issue

Could the problem be because I was building in debug mode, but using the regular .lib files? I have corrected that problem, and now have a new one:

 The program '[1620] SFML Setup.exe: Native' has exited with code -1072365566 (0xc0150002).

In case it matters, I am running 64 bit windows 7 ultimate with 6 gb of ram. Using SFML 1.6.

Thanks for your time!

So I instaled SFML(to the best of my ability) and the Window example runs, but slows down my computer dramatically and throws errors like this:

'SFML Setup.exe': Loaded 'C:\Windows\SysWOW64\winmm.dll', Cannot find or open the PDB file

I think this is a problem with the fact that I am running it on a 64 bit system. What steps do I need to take to get everything working and running correctly?
