Graphics / Scrolling of Tilemaps

« on: February 15, 2009, 04:58:47 pm »

Hi,

i did very much research in this forum how to implement scrolling tilemaps with SFML.

I read the post from Petri Irri how to archive scrolling of tile maps(http://www.sfml-dev.org/forum/viewtopic.php?t=773&highlight=scroll+tilemap). But i cannot get mine to work .

Here's what i got:
1) I got code to load and manage tiles.
2) I can draw a tilemap that fills out the screen. (every tile is 48x48)
3) I can move the player sprite around the screen.

But that code doesn't work too well:

Code: [Select]


       Game Loop:

        // Clear screen
        App.Clear();



        if (Input.IsKeyDown(sf::Key::Up))    OffsetY = -48;
        if (Input.IsKeyDown(sf::Key::Left))  OffsetX = -48;
        if (Input.IsKeyDown(sf::Key::Down))  OffsetY += 48;
        if (Input.IsKeyDown(sf::Key::Right)) OffsetX += 48;

        View.Move(OffsetX, OffsetY);       // Move the player

        App.SetView(View);                 // Draw relative to the world
                // maxHeight /maxWidht are the maximum tiles that are visible
for (int i=0;i<maxHeight;i++)
{
for (int j=0;j<maxWidth;j++)
{
CTile* tmpTile = new CTile(tileNames[map[i][j]]);
tmpTile->getTile().SetPosition ( j*48, i *48);
sf::Sprite sp = tmpTile->getTile();
App.Draw ( sp );
}
}
        App.SetView(App.GetDefaultView()); // Draw relative to the GUI
        App.Draw(Sprite);                  // Draw the player


Did i miss something ?
Should the visible rect of the tilemap be rendered to an image and then being drawn ?

Any help is appreciated !

Thanks in advance,
Chris
