Now I won't be at home till next Sunday, so if somebody will find some time for looking at my code and analyzing it, I will be grateful.

Here I post screenshots that shows how this two objects put on each other:

It's not problem with scalling, becouse if I delete it the problem persist.

I added setting center to loop and it also changed nothing. It seems like the picture is "smaller" few pixels each sides.

I pasted all my code in here:
http://wklej.to/ADnz
There is nearly 300 lines, but most of them are not really connected with that issue and I hope You will catch what is important or not.

I think You don't need animations detalis, but if so there are:
http://www.sfml-dev.org/wiki/en/sources/frame_anim_animated

I have just changed inheritance of class Animated(now it inherits after(?) sf::Sprite - before: sf::Drawable.

I know that it might be hard for You to find what's wrong in stranger code, so I can send You all my project in Visual C++, so You can test what's wrong. If You find time for me of course.

Thanks for advices. I was wondering about it much time


Backing to my moved collision. I changed something it code and not it looks better... but not perfectly. Collision area is a bit smaller than image. Moreover I also use animation from here:
http://www.sfml-dev.org/wiki/en/sources/frame_anim_animated

And that complicates it more. So here I give part of my code, becouse in my opition all is not necessary:

Code: [Select]

Char.SetPosition(512, 384);

    Obstacle.SetCenter(Obstacle.GetSize()*.5f);
Char.SetCenter(20, 32); //fits to image size

    Background.Resize(2000,2000);
    Background.Move(-500,-500);
    Obstacle.Move(100,100);
    Obstacle.Scale(2.f, 2.f);

    sf::Vector2f Center(500,500);
    sf::Vector2f HalfSize(App.GetWidth()*.5f,App.GetHeight()*.5f);
    sf::View View(Center,HalfSize);

    sf::Event evt;

    while(App.IsOpened())
    {
      while(App.GetEvent(evt))
      {
         if(evt.Type==sf::Event::Closed){App.Close();}
         if(evt.Type==sf::Event::KeyPressed&&evt.Key.Code==sf::Key::Escape){App.Close();}
if(evt.Type==sf::Event::KeyPressed&&evt.Key.Code==sf::Key::F1)
{
sf::Image Screen;
Screen = App.Capture();
Screen.SaveToFile("sc2.jpg");
}
      }
   
 UpdateBoy(Char, App.GetInput(), Dir, App.GetFrameTime(), go);
      View.SetCenter(Char.GetPosition());

      App.Clear();
      App.SetView(View);
      App.Draw(Background);
      App.Draw(Obstacle);
  App.Draw(Char);

      App.Display();
   }

And image how it looks like:
http://img96.imageshack.us/img96/1225/sc2ki.jpg

If I made as You said(move SetCenter functions after scalling images it looks as that in my previous post.

In my opinion something still is wrong with setting center, but I couldn't find what).

Is that code which I pasted here all right?

Kind Regards

Thanks really a lot. I am so grateful.

I have one more question. If I want to make collision with more object what is the fastest way to do that? Have I to write all conditions each time?

I tried that way:

Code: [Select]

if(App.GetInput().IsKeyDown(sf::Key::Down))
 {
 if((Collision::BoundingBoxTest(Player,Obstacle)==false) && (Collision::BoundingBoxTest(Player, Obst2) == false))
 {
 Player.Move(0,100*timer);
 lastKey="D";
 CFPS.Move(0, 100*timer);
 }
 else if(lastKey=="D")
 {
 Player.Move(0,-100*timer);
 CFPS.Move(0,-100*timer);
 }
 else
 {
 Player.Move(0,100*timer);
 CFPS.Move(0,100*timer);
 }
 }

Obst2 is my 2nd object that I want to collide with.

But it works not well. The collision place is moved left and up. I have image if you don't understand what I am talkin about:

How to solve that?

Thanks.

I made camera moving with player. I added:

Code: [Select]

Player.SetCenter(Player.GetSize() / 2.f);
Camera.SetCenter(Player.GetPosition());

And then moved my view.


It is almost working. I just need to know why I can't trigger:

Code: [Select]

App.SetView(App.GetDefaultView());

If I use this function collision is not handle and player is moving faster than camera does. On the other hand if I don't use it player is not dimensional (it is smaller than it should be) and collision location is moved a bit left and up.

All my code is here:
http://wklej.to/k602

And class I used for detect collisions here:

I found out where the problem is, but I don't know how to solve it.

I ve done as u had said and I wrote possition both player and collisioner. And I noticed that Collisioner is always on the possition (100,100) (I want it to be there), but my player also has always the same possition (512, 384).

I know that player isnt moving - just view, but I don't know how shouls I do to detect collision is that way. Could you give me any advice?

Kind Regards

Hello all again,
Unfortunately I have next trouble - now with moving map. I wrote code on two ways and both is not working

I need your help then.

My first effort was using this post:
http://www.sfml-dev.org/forum/viewtopic.php?p=5097&sid=f9a1cd64f563b420ac67e1e42a2e2f99

And what I made is:
http://wklej.to/TnAa

And then I tried to do sth myself, but ofc it also doesn't work:
http://wklej.to/f8Nz
Here I even don't see a map

Is here somebody willing to help me?

Kind Regards

General / Collision - example(?)

« on: June 11, 2010, 09:21:37 pm »

But I dont have even any idea. I tried like that, but not working.

Code: [Select]

    if(!Collision::BoundingBoxTest(Ludzik, Przesz))
{
if(App.GetInput().IsKeyDown(Key::Up))
Ludzik.Move(0, -100 * time);
   if(App.GetInput().IsKeyDown(Key::Down))
    Ludzik.Move(0, 100 * time);
   if(App.GetInput().IsKeyDown(Key::Left))
    Ludzik.Move(-100 * time, 0);
if(App.GetInput().IsKeyDown(Key::Right))
    Ludzik.Move(100 * time, 0);
}

I dont know how it should be solved.

Heh, yeah indeed.

I just want that one object can not go into the 2nd one. I want to make that one cannot cover 2nd in one place. No explosions there

Thanks. It works.

And could you tell me what is yours idea to write condition? I mean I dont know what to write in here:

Code: [Select]

if(Collision::BoundingBoxTest(Ludzik, Przesz))
      {
              //here
      }

To make real collision. I found no examples in wiki.

Kind Regards

Your code seeme to test just only one time the collision. What are the size of the two images ? Because maybe "Przesz" is not 100px width nor 50px height...

Does it have to be exactly 100x50? Why? I have the same images and one was scaled to 0,5height and 0,5 width. But also after making it without scaling it is not working.

Your code seeme to test just only one time the collision.

I don t know how to make it other way.

Can you show us the BoundingBoxTest function too please ?

As I said at the beginning(but becouse of that off-topic it is not clear) I m using wiki example from there:
