SFML projects / Re: Bazoik - A clone of the arcade game Berzerk

« on: July 23, 2020, 11:01:08 pm »

Oh man, it'd almost be easier to explain where I didn't use SFML. This code takes advantage of the SFML features you'd expect, like window handling, input handling, sprite drawing, etc. But also, the SFML data types were used quite a bit. Positions are stored as Vector2s, hitboxes are FloatRects, etc. Only a couple other libraries were used, like one to perform line clipping for testing the robots' line of sight, and another to parse XML files.

I have added link to a video to the first post, showing a little over a minute of gameplay. I didn't see a way to embed a video from YouTube.

SFML projects / Bazoik - A clone of the arcade game Berzerk

« on: July 23, 2020, 07:11:59 pm »

Bazoik is a free and open source clone of the 80's arcade game Berzerk. I actually created this in 2018, with a couple friends doing everything that wasn't code. If you do take a look at the code, please know that it's not up to my current standards and doesn't really take advantage of C++11 features, etc. Currently Windows only.

I'd love see hear what you think of the game.

General / Re: Error while capturing resized window?

Sorry, I thought "resize" would be self-explanatory. I did experiment with the MCVE, but you definitely pointed me toward the solution:

txTrans.create( window.getSize().x, window.getSize().y );
sf::View view;
view = window.getDefaultView();
view.setSize( window.getSize().x, window.getSize().y );
view.setCenter( window.getSize().x / 2, window.getSize().y / 2 );
window.setView( view );
txTrans.update( window );
sprTrans.setTexture( txTrans, true );
 

And then after the transition is done, reset the view (because my intention is to keep the image stretched, not increase the viewport):

window.setView( window.getDefaultView() );
 

I'm sure there's optimizations I can do. Regardless, thank you all for your input.

Sorry for the delay, here's a proper MCVE that's exhibiting the same issue.

Okay, hopefully this will show you what you need to know. Anything you don't see defined is a member variable or a #define (defines are all caps). Both of these functions run every frame.

void StateGameplay::ScreenTransition( const float dt )
{
        if( !captured )
        {
                // Capture the screen
                txTrans.create( game->window.getSize().x, game->window.getSize().y );
                txTrans.update( game->window );
                sprTrans.setTexture( txTrans, true );
                captured = true;
        }
        else
        {
                sf::Vector2f move;
                switch( lastMove )
                {
                case Directions::N:
                        move = sf::Vector2f( 0, -TRANS_SPEED );
                        break;
                case Directions::E:
                        move = sf::Vector2f( TRANS_SPEED, 0 );
                        break;
                case Directions::S:
                        move = sf::Vector2f( 0, TRANS_SPEED );
                        break;
                case Directions::W:
                        move = sf::Vector2f( -TRANS_SPEED, 0 );
                        break;
                }

                sprTrans.move( move * dt );

                // State gets switched here
}

void StateGameplay::Draw() const
{
        if( transition && captured )
        {
                game->window.draw( sprTrans );
                return; // Don't draw anything else
        }
       
        // etc
}

It displays incorrectly whether being captured by external software or not. By "capture", I meant the built-in function to apply the window's contents to a texture.

Nope. The only things I'm calling from the sprite are setTexture, move, and getGlobalBounds.

Thank you for your reply, but that didn't seem to solve the problem, even after rebuilding.

General / Error while capturing resized window?

« on: June 14, 2017, 03:42:37 am »

I'm trying to capture the window in order to do a sort of transition effect, but when I capture a resized window it seems to only capture a portion of the screen or display it incorrectly. There are other ways to do the effect I'm looking for, but I'm hoping to get this method working. I am currently developing on Win10 with VS2015. See the following webms:

Default window size: https://webmshare.com/play/Zro60

Resized window: https://webmshare.com/play/jzxXa

This is the code I'm using to capture the window:

txTrans.create( game->window.getSize().x, game->window.getSize().y );
txTrans.update( game->window );
sprTrans.setTexture( txTrans );
