source: ttyvaders/trunk/src/graphics.c @ 20

Last change on this file since 20 was 20, checked in by Sam Hocevar, 18 years ago
  • real Debian package files.
  • two new types of aliens. only one rules.
  • removed gfx_write in favor of gfx_putchar and gfx_putstr.
  • added bonuses at alien death. they do nothing yet.
  • seeker missiles. 'b' to test.
  • weapon resolution is now 16*char. needs to be generalized.
  • fixed the supernova bugs. center could collide with the tunnel, and the last frame was badly displayed.
  • lots of cleanups everywhere.
