After reworking skydiver, I had an idea how to get my score to display on canyon bomber. When I sit down tonight to work on it I had no idea it would turn our like this. Also if anyone has a TI they can play it on can you tell me how it works on the real deal.


Welcome recruits,
We have a critical mission today, the water ways have
become over crowded with vegetation and has completely
shut down the shipping lanes. This must be fixes ASAP.

Your mission will be to take out a bomber loaded with
anti-vegetation depth charges and completely clear tthe
water way. Don't worry about missing as the depth charges
only hurt vegetation and wont damage the canyon. Some
vegetation may be less dense and it may take a 2nd drop
on it to make solid contact, don' despair you have all
the ammo you need to get the job done.

There is another team in route already and will provide
you some competition, should you find this not challenging
enough for you.

Simply fly over the canyon and drop your depth charges by
pressing q or the joystick button. Don't worry about the
wind even though it can become quit strong and change
directions it will have no effect on your mission.

Good Luck men.

The new graphics are very cool... However the original art was so retro!!! Just felt like Bill Cosby was sitting right there with a joystick going out of his mind on Jello pudding!! . Very nice--- this game is quite cool

Nice job with the music playing along.

[jchase1970]

I was kinda hoping the music and graphics (and story line) upgrade would be enough to when me the awesome TI system prize, lol. I've had a system in the watch area on ebay many times but never have bought one. Sometimes I really want one but then I think why when I have emulators, but it would be so fun to have my own programs on my own carts to show people.

I had a little bit of time todat and I was trying to tweak Canyon Bomber, I only needed to shave 50-100 millisecs off the loop. I tried something I didn't know till Adamantyr explained to me that call peek(-31808) was a rnd location. so I played with it and I cant believe that this,
randomize :: call peek(-31808,r) :: ws=2-int(r/255*5)

is faster then this,
ws=2-int(rnd*5)

I'm doing the last few tweeks to the game now and will post the new code in a few days, not much is going to change now, except my son thinks I need ships in the canyon after the seaweed is cleared to complete the story. So I'm going to try and work that in. I did free up 1 line woohoo!

Believe it or not this game runs at a massive 2 frames per second, lol. Well it's a few millisecs shy of that that is why the music isn't smoothly connected at times. I don't want to slow the frame rate to smooth the music, as it isn't to bad in this version and i nthe new tweeked version it is real close to what I need.

I could take out the changing wind speed clouds, but I think that is a nice little extra feature that gives the game a less static feel even though the game is not dynamic at all. Sometimes a simple illusion is all that's needed to fool the eye.

The old version did look nice and retro, and the new version till 30 minutes before posting it here had the same look. But I was trying hard to make it stand out and I decided, I wasn't trying to just copy the 2600 version, but improve on it and use all of the TI capabilities. I feel I have made it enjoyable to play as I couldn't play anymore of the 1st version, it was tedious to say the least, but I have play tested this version alot and still enjoy it.

I don't like the sky but I don't know what to do there. It's seems bland now next to the prettier land and sea textures, But if I jazz it up then the mono color sprites will look out of place so I may be at my graphical limit.

Can't you remove the multiply so that it becomes this :-

randomize :: call peek(-31808,r) :: ws=2-int(r/51)

apparently so, thank you that's another few millisecs, lol.
