Graphics / Animation......again

« on: September 04, 2011, 01:30:59 am »

Hello everyone. Ive made an animation class that inherits from sprite, and uses a subrect to change the frames. Im trying to make a class that holds multiple animation objects. However, the problem with this is that I can't use the functions of sprite with this object. For example say this class was called mario.
I could do Draw(*Mario.getPointerOfCurrentSprite)
but I cant do mario.move()
or mario.SetX() because each Animation(Sprite) has its own location. Any Help?

Graphics / thanks....again

wow sfml has a nice community.thanks for all the help. I finally got an animation class. I based it off the one above.

Code: [Select]


using namespace std;

class Animation : public sf::Sprite {

public:
    Animation(string location,int numFrames,float Delay);
    void setCurrentFrame(int frame);
    int getCurrentFrame();
    void setNumOfFrames(int frames);
    int getFrameWidth();
    void setDelay();
    int getDelay();
    void play();
    void update();
    void pause();
    void reset();

private:
    sf::Image image;
    sf::Clock timer;
    int currentFrame;
    int numOfFrames;
    int frameWidth;
    float frameTime;
};
Animation::Animation(string location,int numFrames,float Delay) {

    if (!image.LoadFromFile(location))
        std::cout<<"unable to load from "<<location;
    SetImage(image);

    currentFrame=1;
    numOfFrames=numFrames;
    frameWidth=GetSize().x/numOfFrames;
    frameTime=Delay;

    SetSubRect(sf::IntRect(0,0,frameWidth,GetSize().y));
}
void Animation:: setCurrentFrame(int frame) {
    currentFrame=frame;
}
int Animation::getCurrentFrame() {
    return currentFrame;
}
void Animation::setNumOfFrames(int frames) {
    numOfFrames=frames;
}
int Animation:: getFrameWidth() {
    return frameWidth;
}
void Animation::play() {
    SetSubRect(sf::IntRect((currentFrame-1)*frameWidth,0,currentFrame*frameWidth,GetSize().y));
}
void Animation::update() {
    if (timer.GetElapsedTime() >= frameTime) {
        if (++currentFrame > (numOfFrames))
            currentFrame = 1;
        timer.Reset();
    }
}

(ignore all the useless functions)

okay so i'm trying to make a animation by inheriting from sf::sprite.However, when I call App.Draw(Sprite), it shows up as a white box.

Oh yeah, this is not related to the problem above, which i found the soluton to.

Graphics / Problem loading images

« on: September 01, 2011, 04:25:17 pm »

Hello everyone, I've encountered a problem with SFML using code::blocks. Whenever I use code::blocks to run a program that has to load an image, it is unable to do so. The console says the reason is : unable to do so. As a result I have to go to the folder where the exe is and run it from there. Help is appreciated.thanks

67

Graphics / figured it out

« on: September 01, 2011, 02:15:55 am »

So i found out why the image was white. When I run  the program from code::blocks, the image doesn't load. I tried it from the actual folder where the exe is and it works fine. I tried running code::blocks with as admin, but doesnt work. lol sorry for so many posts.

Graphics / new problem

« on: September 01, 2011, 02:09:05 am »

lol never mind i got it. Aaaaaand theres a new problem. Every time I restart my computer or log off and back on, the loading images dont work. All that sows up is a white image. However, when i start a new project, the image loads properly, even if its the same exact code!!As soon as i log off, the project becomes corrupt, and i have to start a new one. PLZ HELP. im gonna cry...

Graphics / back again

« on: September 01, 2011, 01:22:24 am »

soory guys for the break, but i was going back to basics with sfml. Anyways, I was doing clocks all over again and I did this, which was posted by one of the posters in this thread.

Code: [Select]

if (timer.GetElapsedTime() >= 1) {
            if (++whichOne > 2) {
                whichOne = 0;
                timer.Reset();
            }
        }

std::cout<<whichOne;



This is what it produces:





Its supposed to constantly say zero, one then two, for the same amount of time, but it does 0 for 1 second, then quickly 1 and 2. Help!

I know I suck at this, but an example code would be very very useful.

Graphics / my try

« on: August 24, 2011, 06:24:54 pm »

Hello Guys, I tried this but it doesnt works. The image stays the same unless I press the Right button.

Code: [Select]


#include <iostream>
#include <SFML/Graphics.hpp>

using namespace std;
//using namespace sf;

int main() {

    sf::Sprite marioSprite;
    sf::Image run[3];
    sf::RenderWindow App(sf::VideoMode(800, 600, 32), "JustAnimation");
    int whichOne = 0;
    sf::Clock timer;

    if (!run[0].LoadFromFile("resources/0000.png")) {}
    if (!run[1].LoadFromFile("resources/0001.png")) {}
    if (!run[2].LoadFromFile("resources/0002.png")) {}

    marioSprite.SetImage(run[0]);

    while (App.IsOpened()) {
        App.Clear(sf::Color::Black);

        sf::Event Event;

        if (App.GetEvent(Event))
            if (Event.Type == sf::Event::Closed)
                App.Close();

        App.Draw(marioSprite);

        if (timer.GetElapsedTime()<100) {
            whichOne=0;
        } else if (timer.GetElapsedTime()<200) {
            whichOne=1;
        } else {
            whichOne=2;
            timer.Reset();
        }
        marioSprite.SetX(marioSprite.GetPosition().x);

        if (App.GetInput().IsKeyDown(sf::Key::Right)) {
            marioSprite.SetX(marioSprite.GetPosition().x+2);

        }

        marioSprite.SetImage(run[whichOne]);


        App.Display();
    }

    return 0;
}
