Crazy Lander

View File

Crazy Lander is another (mostly) BASIC game for Commander X16. We will introduce some new technologies not used before in our projects. It is a variation of Lander type games where we have to guide and land the space capsule to dedicated platforms using thrusters and navigating through natural and man-made obstacles. To make the game more challenging we have to be mindful of the fuel used and land gently. Few highlights:

  • Running in bitmap mode
  • It is a game of precision so we have to assure pixel perfect collision control
  • Animated obstacles unique to each level
  • Music and sound effects

Project Specs

  • Emulator Version R.38
  • Low resolution bitmap mode 320 x 240 in 16 colors on Layer 0
  • Use the menu system to choose difficulty, turn music on and off, display instructions, quit and of course start the game
  • Animated sprites for displaying capsule as well as thruster exhaust and explosion animation
  • Tile layer 1 is used for HUD and for messages and menus
  • Assembly subroutine for pixel perfect collision detection
  • 4 distinct levels with flexibility to add more
  • Scoring is based on the landing platform multiplier times the remaining fuel
  • Keyboard/Joystick controls
    • Left Arrow / Joystick Left fire left thruster pushing lander right
    • Right Arrow / Joystick Right fire right thruster pushing lander left
    • Space / Fire button main thruster pushing lander up
  • Music in the background using Music Library for BASIC programs
  • Sound effects using direct programming PSG from BASIC using VPOKE
  • 256 color splash screen

Hey Dusan, this looks very cool from what you wrote. But I cannot get it running, neither in the "Try it now" section, nor after downloading all the files (individually) locally. In both scenarios, the program gets stuck at the splash screen with blue lines going from top to bottom.

Are you using Rev 38?

I noticed the same thing with the "Try it now". Will try to troubleshoot in coming days. I am using R38 and just tried downloading files into clean directory and it works fine for me.

I haven't tried it in R39.

Found the issue: it's because "FONT.bin" is not in all-caps. This is a non-issue for the Windows users, but for Linux and the Web emulator it is. Simply change the name to all-caps and it will work.

Awesome. Thanks for the help, just changed it and now it works.
