Now it´s playable - defend the ISS. You only can fire if you move. Don´t hit the iss. Avoid collisions. Youtube-Tutorial and bas-code will follow. Please try the game and tell me if it is fun - or not .

donnerkuh · September 15, 2021

nearly finished - try Tutorial16bas.bin . open points: collision-detection enemy fire

donnerkuh · September 16, 2021

HI. The game is finished. There are 316 bytes free for your ideas. Please try the game and send me your scores - give me feedback and tell me bugs. Be a testplayer - Thank you .

donnerkuh · September 24, 2021

Final Version 1.0 released - have fun, try and if you have ideas for ISS 2 then let me know .

Tested your new game on the PlusCart today (thanks to @Prizrak for uploading), here's one of my scores:

Quote

give me feedback and tell me bugs.

here is my feedback:

the ship should stay in the last direction it moved and not switch back to the upright position.
the (random) ship rotating is annoying.
there was one situation where I respawned and the enemy was at the repawn point (instant dead).
the game should be a bit faster.
exit function gets triggered when pushing Reset on the game over screen after the game was finished with joystick in right position (please read the joystick in the Game Over screen loop)
@ZeroPage Homebrew will surely complain that it is not "couch compliant"
the explosion animations and sounds are OK, but can be improved (more animation frames?).
would be cool if the ISS would move too. (difficult, but vertical scrolling should be possible with PF-graphics)

Don't MAKE me get up off this couch! ;-)

But seriously, I'm looking forward to playing the game on an upcoming show @donnerkuh, probably the next 2600 day.

Really cool game.

Simple and addictive arcadey gameplay.

As a suggestion, I think you could make a better title screen using sprites instead of PFpixels.

Maybe something like this:

Thank you for your feedback - i think i will have to work on an ISS-Patch

the ship should stay in the last direction it moved and not switch back to the upright position. <- the problem is, i have no more variable free, but this will need one. I will find a way to change it.

the (random) ship rotating is annoying. <- i know

there was one situation where I respawned and the enemy was at the repawn point (instant dead). <- i tried out and you are right - this is not fair. i will fix it

the game should be a bit faster. <- if you are more successful, the gamespeed will increase. The enemy will be faster and faster

exit function gets triggered when pushing Reset on the game over screen after the game was finished with joystick in right position (please read the joystick in the Game Over screen loop) <- i don´t know what you mean (kannst du mir dass nochmal auf deutsch erklären, was genau passiert?)

@ZeroPage Homebrew will surely complain that it is not "couch compliant" <- insult to majesty, i will do everthing to make it "couch compliant"

the explosion animations and sounds are OK, but can be improved (more animation frames?). <- the game is limited to 4 KB, only a few bytes are free. Maybe one more animation frame...

would be cool if the ISS would move too. (difficult, but vertical scrolling should be possible with PF-graphics) <- I´ve never made a scrolling game. This will be my challange for ISS 2.0

I am not sure if you know this, but for variables with only two possible values(0 and 1) you can use variables as array of bits, so you use one variable as 8 bit variables.

I.E

   dim _Bit0_interruptor0=c
   dim _Bit1_interruptor1=c
   dim _Bit2_interruptor2=c
   dim _Bit3_interruptor3=c
   dim _Bit4_interruptor4=c
   dim _Bit5_interruptor5=c
   dim _Bit6_interruptor6=c
   dim _Bit7_interruptor7=c

You assign values using the index {}

I.E

    _Bit0_interruptor0{0}=1

And test them as boolean

if _Bit0_interruptor0{0} then ...

or

if !_Bit0_interruptor0{0} then ...

Die PlusCart (evtl. auch bald UnoCart und Harmony Cart) hat eine Exit Funktion eingebaut, sodaß man während des Spiels zurück zum Menü kommt. Hierzu muss der Benutzer den Joystick nach rechts drücken und gleichzeitig den RESET Knopf drücken. Da die Cartridge die Ports nicht alleine lesen kann funktioniert das nur wenn das ROM "mitspielt" d.h in jedem Frame beides liesst sodaß die Cartridge mitlesen kann.

Or maybe use a graphics/animation that looks more like a explosion

No.

if _Bit0_interruptor0{0} means if _Bit0_interruptor0{0}=1

c=%00000000 <-- if this bit is 1

---------------------------------------------------------------------

if !_Bit0_interruptor0{0} means if _Bit0_interruptor0{0}=0 (or if you want if _Bit0_interruptor0{0}!=1)

c=%00000000 <-- if this bit is not 1 (hence is 0)

---------------------------------------------------------------------

{0} is the index (which bit is being evaluated)

ah - i found it - your description and the batari basic commands site will help to expand my options. thank you again!

KevKelley · October 5, 2021

Cool to see all the improvements. I need to give this another go.

donnerkuh · October 6, 2021

Game patched - use version: 1_0a02.bas.bin :

- your ship will stop in the same position it has moved (not look up if you stop)

- you will shoot in this direction (no joystickmove needed press fire only)

- explosion looks like a explosion now

- Nice (from vhzc stolen) Title-screen ?

Thanks to vhzc and Al_Nafuur for tips and motivation

Nice update. the changes to the ship behavior really enhanced the game experience imo.

The respawn of the enemy should no longer cause an instant death. Have fun (with not dying immediately)

You're welcome, it's a very challenging game and a really great premise! We had fun playing it last night trying to survive.

Hahah, yes, 'couch compliant' means that all menus, controls, options can be done through the controllers so you don't have to get up off the couch to press reset etc. on the console. ;-)

Thank you for making the game!

+discotronic · November 3, 2021

I do like this game and the concept. Please keep going! Right now it is a very good challenge. Hopefully you continue with the development.
