Wonder if an Atari 7800 Basic course on Udemy would succeed

[Wonder if an Atari 7800 Basic course on Udemy would succeed]

Throw in a course on 7800 assembly and I'm game.

Judging by the latest video, the use of semitone sound effects and what appears to be 320 mode backgrounds are quite impressive. Possibly one of the best 320 screen mode games I have seen.

[My 7800 Vertical Shooter - Heofonfīr]

I decided to write down some notes in regards to what I have learned over the months.

1. Be sure to set up what you need.

2. Be sure to dim your variables, properly plot them, and never dim labels.

3. '&&' comes in between 'if' and 'then'; ':' always comes after 'then'.

4. All subroutines must be placed after 'goto mainloop'.

[7800 XMAS : Santa vs. The Nightmares (very early demo)]

Aside from the enemies going through Santa and his reindeer, this is quite solid.

[Holodeck - a travesty of life]

That looks astonishing, and I look forward to it getting finished.

Here's some new progress on an older source file:

 

I also would like to mention that it took a few minutes to realize that syntax error.

Quick update: I just added a continue screen routine to my other demo. However, here's the catch:

--- Unresolved Symbol List

BREAKPROTECTOFF          0000 ????         (R )

0.playerX                0000 ????         (R )

0.titlescreen_loop       0000 ????         (R )

 

   stack allowance: 30 nested subroutines.

   the canary is situated at: $1c1

   873 bytes of ROM space left in the main area.

             790 bytes of ROM space left in DMA hole 0.

     $1880 to $1fff used as zone memory, allowing 15 display objects per zone.

     2310 bytes left in the 7800basic reserved area.

Congratulations for getting this finished.

What you have is solid, but the two character mugshots could use some better colors.

@MuddyfunsterThanks, and points taken. As a token of my gratitude, here's the latest source. Oh, and I tested the latest build in Bup System, and it works.

It has been over one month since I last touched this, but I'm still confounded on how to get the return to title screen to work upon the Game Over screen. Here's the subroutine:

gameover_loop
    if lives<1 then gameover_flag=1:clearscreen
    plotchars 'Game Over!' 0 40 16
    if joy0fire then fire_debounce=1
    if !joy0fire then fire_debounce=0
    goto gameover_loop
    if fire_debounce=1 then clearscreen:goto plot

What also needs to be done:

-Get the laser power-up working

-Get the explosions to work properly

-Get the firing sound effect to work properly

-Get the Lives and score to display properly

It takes a lot of balls to use Internet memes in a test program.

Matt, I wonder if you have anything planned for item tables, individual levels, or even boss battles if one is inclined?

[Odynexus, a new Atari Lynx game!!!]

@agradeneuYou are the pixel artist that far too many Lynx games should have had. However, for the final version, I suggest that LV. 4 have another sky color other than magenta.

[Collisions with Irregular Tiles]

Pat, did you write demos some time in the past?

[Plink]

I really like the particle effects that were used in the title screen.

[My 7800 Vertical Shooter - Heofonfīr]

I'm currently writing in a Twin laser power-up for the shooting demo.

power_up_obtained
    if power_upFlag=1 then 
    if joy0fire && joyposup=1 then twinlaserY=twinlaserY-10 : playsfx sfx_plainlaser
    if joy0fire && joyposdown=1 then twinlaserY=twinlaserY-10 : playsfx sfx_plainlaser
    if joy0fire && joyposleft=1 then twinlaserY=twinlaserY-10 : playsfx sfx_plainlaser
    if joy0fire && joyposright=1 then twinlaserY=twinlaserY-10 : playsfx sfx_plainlaser
    if !joy0fire then twinlaserX=playerX+2:twinlaserY=playerY-8

No build, just the source files this time.

Using Wide sprites to optimize for speed, that's pretty clever.

You have an excellent engine so far, and your sound driver is really solid. Just keep at it.

Here's my latest sprite for one of the player characters.

[My 7800 Vertical Shooter - Heofonfīr]

A work in progress version of a 160B player select graphic. I decided to go with that because it would be easier to work with instead of trying to layer sprites for the player select.
