Snake

[vicist]

A Worm/Snake game I made as a proof of concept (to me) programming exercise.

Added joystick/fire control for those who like that sort of thing.

Link updated.

Thanks will give this a good try.

Nice that the game gives me some time to think about where I'm going.

Here things start to get crowded!

Whoa.

I got to 138, but usually when I finally die it doesn't feel like it's really my fault.

I realise it's just a programming exercise but if I had a comment for it I would say the controls are not responsive enough. I will be going straight down the screen then I'll press 'right' then 'up' but the right doesn't respond so it eats itself and dies.

[vicist]

It's written in BASIC and there is quite a bit going on in-between key-presses so it's never going to be super responsive.

However, I have looked at the way the key-presses / joystick detection works and tried a different approach.
See if this is any better.

EDIT: This is the same file now as the original post.

Yeah definitely feels better now far less sluggish.

Still get the occasional moments of it but as you said it is a basic program.

[vicist]

As snake_b works a bit better, I've replaced the original post with this one plus a fix to the slightly glitchy score display.

Enjoy.

Hm, my new attempts are worse that my previous, either with joystick or, more controlled, with keys.
I held a direction too long and ran into a wall while winding around to get the long tail out of the way

Will try the updated version later today,thanks.

This was a good candidate to build a WimBasic version of....It is now suitable for all (regular) memory configurations and uses a lot of the WimBasic features.
I brought it down to a little over 2k bytes.

Wim.

Works well

Brought it down to 1967 bytes in WimBasic, 42 lines. The WimBasic features sped it up, but a big winner was the use of defined functions.
I applied these to calculate the next memory location for PEEK and POKE.
This can also be done in vanilla Basic and saves processing programlines and searching for variables.

Code: Select all

DEFFNP(X)=X+300*(X=1020)-157*(X=767)
DEFFNQ(X)=X+251*(X=924)-108*(X=720)

Then call them with PF=FNP(PF+1) etcetera.

Another one is the line where variable B is compared to the body or the tail of the snake or the border. These three comparisons can be changed to one, namely: B<99 . This also saves a lot of processing.

Regards,

Wim.
