2 players?

[ZippyRedPlumber]

Starting to continue progress on my 2600 homebrew, How does one implement 2 player Co-op like in Mario Bros. & Joust?

What tricks should I use?

I'm not sure what you are asking exactly. What part of two player simultaneous are you wanting help with? It should be just a matter of reading two controllers, and moving two player graphics and/or missiles accordingly.

Exactly. If you know how to implement the logic for making a one player game, you basically already know how to make a two player game, there would be no real special tricks involved.

 

What have you tried so far, and what kind of problems are you having?

After watching New Retro Show's recent vid on 2600 games, after seeing 4-Mula, I want to use the score as a level status & enemy counter. How can this be done?

[Captain Spazer]

I would use the custom score editor. You can customize the score display a lot to show sprites instead of numbers etc:

Made some backgrounds using the image converter, I want to this. (Pictured Below)

 

 

How can this be achieved?

The "ASM background" would just be higher resolution playfield plus a background color. You won't be able to do the very edges of the screen with any version of bB that I'm aware of, but you can do a higher resolution playfield with the DPC+ kernel, the Multisprite kernel, or with the standard kernel if you make use of Superchip RAM.

You could probably play around with:

 

 set kernel_options pfcolors no_blank_lines background

 

I'm thinking that'd give you a colorful background with single color playfield blocks.  Although you'd lose a missile.

 

But, the original question wanted 2 players and what I suggested only has 2 sprites.  In my scrolling game and in Princess Rescue the players sprite and enemy/item sprite take up all the available, er, sprites.

I can make my player move in all directions, But I want him to move left & right & jump can anyone supply me with easy to understand platformer code?

 

Below is a demo

@Random Terrain has a pretty good platformer starter example with jumping, etc.

Thanks @Karl G, but I want it to be simplified as I'm still new to Batari.
