1.1.0 / 2023-07-26¶ ↑

• 3 minor enhancements:

  • Added anti-aliasing to polygon. Want to add filling at some point.

  • Requiring ruby 2.7+. Too many changes to ruby internals to try to maintain.

  • polygon now takes an array of points.

• 4 bug fixes:

  • Updated to work with SDL2. This will break some things, but mostly works.

• 58 minor enhancements:

  • bezier now takes an array of any number (> 4) of points.

  • blit and put now do everything in one call. Should be more performant.

  • blit and put now use the clear color of their class for the background.

  • clear will now warn and skip if color isn’t known.

  • fps now takes an optional color

  • transform/put now explicitly rotate on their bottom-left corner. Shifting x is no longer necessary.

  • AbstractRenderer#initialize clears and presents so frame 0 is correct color.

  • Added DEBUG_COLOR and use it in debug. Reversed in WhiteBackground.

  • Added Renderer#copy_texture.

  • Added Renderer#h and w to return the output size.

  • Added default (empty) Body#update.

  • Added unary negation to V.

  • Alpha blending is massively improved. Black on white is black.

  • Blit now ensures blending is on.

  • Check for done before paused so ‘esc` can quit while paused.

  • Extended Renderer#point to optionally read or write a pixel.

  • Improved default window naming to add spaces to the classname.

  • Moved Screen#flip to Renderer#present.

  • Moved Screen#set_title to Window#set_title.

  • Moving everything out of Screen class. Will remove or leave just for constants.

  • Removed KeyEvent#unicode.

  • Removed PixelFormat#colorkey and alpha.

  • Removed SDL::WM and set_caption. Set titles via screen.title=

  • Removed Simulation#alpha, now built into pixels directly.

  • Removed Surface#color_key and Surface#set_color_key.

  • Removed Surface#flags and Surface#set_alpha.

  • Removed Surface.blit class method.

  • Removed Surface.new. You only create surfaces via Font.render_text and sprite.

  • Removed bpp argument to AbstractSimulation#initialize.

  • Removed/changed a lot of constants, mostly around KeyEvent handling.

  • Renamed AbstractSimulation#rgb to rgba. I think this should probably just go?

  • Renamed PixelFormat.get_rgb to get_rgba.

  • Renderer#fast_rect now just calls Renderer#draw_rect w/ true for filled.

  • SDL2 properly supports RGBA. Switched to it entirely.

  • Screen#open now stores off a renderer, window, and texture in the Surface.

  • Screen.open no longer creates or stores a surface. Saves off its own PixelFormat.

  • Search Ubuntu font directories in find_font. (phiggins)

  • Simulation now defaults to half-width and half-height. No more required args to super.

  • Surface#save now saves off PNG.

  • Switched Renderer and Window to subclass Data, not Surface.

  • Switching to SDL2_gfx for primitive drawing and rotozoom.

  • Transforms now default to anti-aliased rotations.

  • Updated graphics_setup.sh to remove SDL1 and install SDL2 (on OSX).

  • V#magnitude is now cached.

  • graphics_setup.sh will install hoe if necessary.

• 15 bug fixes:

  • Cleaned some off-by-one drawing bugs. I think it is more pixel perfect now?

  • Cleaned up Numeric#degrees.

  • Finished getting to 100% rdoc coverage.

  • Fixed a memory leak in PixelFormat. Might remove it entirely.

  • Fixed a memory leak in collision maps.

  • Fixed an off-by-one in blitting.

  • Fixed bugs in hline and vline not using correct defaults. (joshcheek)

  • Fixed circle and ellipse. Filled + anti-aliased wasn’t actually anti-aliased.

  • Fixed examples/boid.rb to rotate bodies again.

  • Fixed examples/canvas.rb to draw in black again.

  • Fixed fps drawing bug in rainbow_fluid.rb

  • Fixed graphics_setup.sh and Rakefile for linux.

  • Removed Graphics::Surface::VideoMemoryLost.
