GoSub (WIP)


Recommended Posts

Yes, but I changed the variable before it starts so that when joy0fire0 is pressed on the title screen, keygot{1} changes to 1. I changed it so when joy0fire0 is depressed keygot{1} becomes 0, the part I forgot to do. I have a 2-button joystick and I tested firing with both buttons.

Hi atari2600land,

 

I ran some tests between the A7800 emulator and hardware:

 

GoSub v31

A7800:
proline_joystick = works (right/button 2 only)
vcs_joystick = doesn't work


Hardware:
Atari 7800 Pro-Line Joystick = works (right/button 2 only)
CX40 Atari VCS Joystick = doesn't work

 

 

GoSub v32

A7800:
proline_joystick = works (right/button 2 only)
vcs_joystick = doesn't work


Hardware:
Atari 7800 Pro-Line Joystick = works (right/button 2 only)
CX40 Atari VCS Joystick = doesn't work

 

They matched exact in behavior. 

Hope the above helps in your troubleshooting.

Just a guess atari2600land, but did you have a single-button joystick plugged in when you powered on the console, and then switched to two-button sticks? That would have kicked in the single-button electrical short protection, which would have disabled two-button mode. If it's not that, then maybe there's a problem with your console?

 

Anyway, it might be better if your game also worked with single-button sticks. You can do that by checking for joy0fire1 instead of joy0fire0. (more on that in the docs)

Changed the life system. Now you get 3 chances to complete the level on every level, so the lives don't carry over to the next level. I thought it would be better since some of the levels with the shark are kind of difficult and it wouldn't be fair to the player. I added two new levels so I'm up to 16 levels now, and 7,366 bytes left for more.

Added 2 new levels. There's now 18 levels. I have 6,460 bytes left, which means I have room for 17 more levels. Here's what I plan to do:

The game will have 30 levels. At the end of the thirtieth level, there will be the final boss fight, and then there should be enough room for a little ending.

Decided to work on this again some more. Added a new level and a new item: Teleporters. If you touch one of these things, you'll be transported to the other one. Just be sure to not touch the joystick when you enter these, or else you'll be going in the same direction you were heading and might run into the coral wall. The teleporters will reset your sub's direction and it will start at not moving.

(The teleporters are the red ringy things.)

Hey man,

great job, this is turning into a great arcade game !

 

Have you thought of giving the octopus the shark and the torpedo, some frames of animation ?

Continue. The dimensions are 8x8 and a maximum of 3 different colors. I especially like the octopus, but I want him to have 2 eyes.

OK everything is 8x8 and converted into your palette !

I got carried away and animated everything.. you keep what you need.

I don't know how many frames you can fit in.. so details below:

 

Torpedo 2 frames in each direction

Sub 2 frames

Key 3 frames

Treasure chest 2 frames

Shark 2 frames

Octopus 4 frames

Crab 2 frames

Teleport-er 3 frames

 

I can see you are still using the first version of the sub, this is modified.

As an added hazard in later stages, the crab can walk on the seaweed and extent it's claws randomly from time to time.. just an idea.

Let me know what you like, to send you the individual sprite-sets !
