Platformer source

[+batari]

Here is Gingerbread Man source stripped of all game-specific code except the platformer engine itself. If someone wants to build a platformer based on this, go ahead. I figured the physics model and background detection might be useful to someone.

 

I kept in the man sprite and second level screen data for illustration purposes, but please change these if you use this as a base for your own game.

 

Variables f-z are free. Enjoy!

Thanks. Maybe I can use this as the skeleton for my platform game instead of reinventing the wheel.

That's pretty impressive! Nice work!

Thanks! I assume the code will not work with the standard kernel?

I might make a version that works with the standard kernel.

That would be cool.

Yep, that would be really cool!

I modified the engine to work with the standard kernel. One uses Superchip RAM to allow a playfield with the same block size as the original, and another uses larger blocks as found in the standard kernel. I decided to optimize each for bankswitching, so the game loop is placed in the last bank. This reduces the number of cross-bank accesses when reading playfield blocks. This code should still work if you decide to add pfcolors or no_blank_lines.

 

I also included a multisprite version optimized for bankswitching.

This is awesome! Thanks!

Sorry if this is something simple but I am new to Batari Basic and am getting an error when trying to compile the samples you provided. The error is "Unknown Keyword: def". I have made a few changes to the playfield, but don't think that would cause an issue as I only changed a few "." to "X" keeping the correct number of characters in the line.

 

Thanks.

Sorry - you need the latest build for that, and it's not yet on the website. To install, unzip the file where bB is installed and overwrite the 4 executables.

I thought I had the latest. I will give it a try.

That did it. Thank you for your assistance.

Where May I download the last executable ?

You should be able to grab the latest from this thread but as you'll see at the end there are other issues using it.

Would be awesome with a version of this that worked with the none 64-bit version of VBB
