New Basic game: Captain Scram

[tibasic]

Hello,

 

Here is a scramble-like game called Captain Scram written in TI Basic on the unexpanded machine, well in Classic99. I think it is more or less complete.

Nice done! Really playable and entertaining with excellent graphics. The decision not to animate the laser fire is excellent and does not take away from the game. I wonder if in a future version the enemy would fire back at you occasionally, perhaps giving you a second or two warning by changing color.

I like, a good TI-Basic game.

 

i am arrived to level 5 but something changed because i lost

That's a good score ti99iuc. I have been in the 400s.

 

Level 5 was designed to be a little tricky to make up for the targets not firing back. I think it should be possible to complete it but may take some concentration. I will check it again.

 

On completing level 5 you should get some bonus points depending on how many ships you have left.

[ti99iuc]

oh yes, it's clear i'll try again

 

I also would like to see a new enemy each level update

[Retrospect]

Yeah Ciro's good at getting the high scores. He can beat me at games that I've written!

 

Hey I love this game, TIBASIC. It's great I enjoyed it. One of the hardest things to do, on the TI, is getting a stock TI Basic game to run at a playable pace and you did it again.

[tibasic]

Thanks Retrospect. It's a lot of fun doing these games! I enjoy writing these games on the bus and train to and from work.

 

so ... it looks like I may have messed up with the collision detection a bit and that is why level 5 is too difficult.

 

These adjustments to the code below seem to fix the problem:

 

Change line 1410 to:

1410 IF SET=11 THEN 1420 ELSE 1500

 

Change lines 1940 and 1950 to:

1940 Y=Y+1
1950 SET=SET+1

 

And delete lines 1960, 1970, 1980 and 1990

 

I think that should do it.

 

I may try adding some new mystery targets into the higher levels that occasionally pop up where extra points can be scored.

That looks like Laser Gates:

 

Now, I need to find time to try it!

Is the game done or are you planning further improvements? I'd like to post it on the TI Gameshelf

[tibasic]

Hi Vorticon, yes I have a couple of small improvements in the works. Hope to finish them later this evening or tomorrow.

[tibasic]

I have attached a new version of the game to the first post. It includes the improved collision detection, new target characters, new system of scoring (more points at higher levels) and an extra target appears during each level, i.e. at times there are two targets to chose from. Enjoy!

[ti99iuc]

Oh yeah, it seems to be better and also more enemy i can see ! many thanks

[tibasic]

Whoops not supposed to be so many targets!

 

One of the targets was not deleted at the end of the level ... I've just fixed that and attached the new version to the first post again.

 

Thanks for trying it.

Game is up on the TI Gameshelf site. I corrected a minor typo in the instruction screen where you had E and D as the up and down commands instead of E and X which the game requires.

[tibasic]

Thanks Vorticon for correcting the instructions and uploading to the gameshelf site. For some reason I can't see it in the basic section ...

 

Ah ok it suddenly appeared! ​

First time playing through - no idea how I did so well. Difficult to control (lag) when it gets to the 5th level. I understand why it does this, that being the limitations of TI BASIC scanning the keyboard, updating the screen and playing sounds. Fun little game. Looked like Vanguard when I first saw it, and still seems a bit like that now that I've played it, just not with the 4-way firing. Would have made an impressive type-in program in COMPUTE or 99er back in the day! Very nice work~!

Thanks! We had Home Computing Weekly and Computer & Video Games magazines where I was. It was very exciting typing in those games.

Apart from when C & VG would put their pictures over the written code making it illegible lol

This was the first run through for me. Up and down motion seemed a little sluggish and ended up killing me on level 5.

[tibasic]

Well done! You got to level 5 which is not bad for a first go I think as you had the somewhat sluggish controls to contend with. My advice for level 5 is to concentrate only on the flying and to ignore the targets. Once you get the timing right it is possible to get through it fairly easy although it takes a fair bit of concentration and seems like it's never going to end. Although it does end as can seen with the final score shown in the attached image.
