[[IntyBASIC] More advanced tutorials - suggestions]

Thanks, I'll check out your demos and see if I can get a better handle on sound generation

[[IntyBASIC] More advanced tutorials - suggestions]

I would definitely be interested in a IntyBasic tutorial for Sound Effects. My efforts thus far involve a lot of guesswork and poor results.

 

I tried messing around with PSGtinkerer but did not have much success.

 

Anyone providing some basic instruction in the sound department would be greatly appreciated !!

[pause / resume]

@nanochess and @intvnut -

 

Thanks, the code listed above appears to work - 1 & 9 to pause and 1 & 9 to resume the game. I need to test further but so far, so good

 

I appreciate the excellent and prompt support as always, along with the explanation and commented code.

 

Sincerely,

Derek

[pause / resume]

@intvnut - thank you for the clarification, especially the follow-up post. So far I've been unable to find any tutorials or other sample code which includes any "debounce" code (at least, it's not commented as such).

 

If there is an optimal way to handle this in IntyBasic, I'd appreciate if someone could share the solution. I must not be the only one struggling with this

[pause / resume]

The code provided resolved most of my issues. I'm still experiencing an activation of the function mapped to CONT.B0 when I press 1 & 9 simultaneously.

 

I confirmed that pressing 1 or 9 separately does not cause this function to activate.

 

Thanks again for the prompt response! I appreciate the detailed explanations as I attempt to pick up where I left off with IntyBasic after a 15-month absence.

 

Sincerely,
Derek

[pause / resume]

@Intvnut - Thank you for clarifying, I knew there was some "magic" behind the way the controller keys were decoded but I was having trouble finding the specific details. Appreciate the detailed response

 

 

I implemented your suggestion and it "sort of" worked... the game pauses as long as the 1 and 9 keys are held down.

 

However it still activated the code for the top button and the game resumes as soon as I release the key(s).

 

 

I could just utilize a single key for the pause functionality, but hoped to use the 1 & 9 keys to be consistent with other Intellivision games.

[pause / resume]

I'm trying to implement a simple pause/resume feature using the standard keypad combo (1 and 9). Also tried with 3 and 7.

 

Either attempt instead results in a button press. If I modify the first line of code to IF cont.key = 4 THEN

 

it works as expected. I assume this is one of those key combination results in other button / disc pressed scenarios?

 

Please advise as I'm under the impression that a workaround exists.

'check for pause key combination
IF cont.key = 1 and cont.key = 9 THEN 

junk = 0

pause_loop:

if junk = 0 THEN PRINT AT 84 COLOR ((RAND AND 5)+2)+BG_BLUE,"PAUSE"

'increment timer to change color of pause text

junk = junk + 1

'if any key, button or disc is pressed, resume game

Wait

if cont.button or cont.left or cont.right or cont.up or cont.down then gosub checkforNOKeys: PRINT AT 84 COLOR FG_BLUE+BG_BLUE," ": Gosub WaitaBit: goto resume_game

if junk = 25 THEN junk = 0

GOTO pause_loop

resume_game:

END IF

[Mermaid (Intybasic) - castle map using GROM]

@Kiwi - I tried MODE 0,1,2,7,6 - same results.

 

@Carlsson - no warnings when I compile.

 

The "constants.bas" file indicates latest revision of 1.22F with a file creation date of 1/23/2016.

[Mermaid (Intybasic) - castle map using GROM]

I sent you a PM. Just to clarify, I did set the mode to SCREEN_CS at the top of the "display_castle_map" procedure.

 

I'm trying to reproduce the GROM with lowercase and graphics in the "drawgrom" procedure.

[Mermaid (Intybasic) - castle map using GROM]

After an extended vacation from coding, I have decided to continue work on Mermaid.

 

I'm encountering the following issue after compiling the code with IntyBasic 1.2.8 (I think I was using 0.9 or 1.0.3 when I was compiling prior versions - not 100% certain since my laptop expired in the interim).

 

The game executes properly, however the castle map is displaying the incorrect tiles (see "mermaid_incorrect_tiles.jpg" attached)

 

I have included a partial sample of the code that generates the map along with the "grom_debug" code that I used to generate the test image.

 

When the code was working properly, I was using the picture tiles with the bars and triangles to depict the rooms that you have visited within the castle.

 

The attached screenshot confirms that the same code is executing properly with the binary that I compiled shortly after the contest ended (again, under the assumption that I was using IntyBasic 1.0.3 or similar code level in early 2016).

[IntyBasic - using PRINT AT for background images]

perfect, that worked like a charm!! Thanks again!!

[IntyBasic - using PRINT AT for background images]

Thanks for the quick response! I will give that a try. I already implemented a number of loops and a few other tricks to consolidate the code. I'm sure there is more optimization that I can do but trying to squeeze in a few more features before the contest ends :-)

[IntyBasic - using PRINT AT for background images]

I have been using the following statement to print certain background objects on the screen in my game for the IntyBasic contest.

 

in this example, I am placing a "wall" image to cover an entryway in the castle:

PRINT AT 9, $1860

PRINT AT 10, $1860

However I am getting an error in jzintv when I attempt to execute the ROM now.

Starting jzIntv...

HALT! PC=7004 Instr = 78 MS = 62

If I comment out a handful of the PRINT AT statements, the ROM executes properly.

ROM is currently hovering between 17-18k so I wasn't sure if I was up against the limit (without bankswitching).

I have used the above PRINT AT statements elsewhere in the program and they execute as expected. The image ($1860) output is correct when I reference it in the screen [label] statement.

Please advise, perhaps there is an alternate method to perform this task.

[Entry 2015: Mermaid]

no videos yet, I got a late start (December 1) - trying to iron out a few issues with the creature movement and complete as many sections as I can before the deadline.

[Entry 2015: Mermaid]

@GroovyBee, thanks that worked like a charm! It did not occur to me to use the FG_WHITE+BG_BLUE combination with the print command.

[Entry 2015: Mermaid]

I am working on a late entry, inspired by my daughter's request to create a video game for her.

 

The working title is "Mermaid". The objective is to collect treasure and locate the queen's crown along with the key to the underwater castle while avoiding various sea creatures including the shark, octopus, squid and a variety of fish.

 

The mermaid can protect herself with a "mermaid bubble" (force field) and also has a "speed boost" option to briefly increase her swimming speed.

 

Once you collect the key and the crown, locate and enter the castle. You need to deliver the crown to the queen before time expires.

 

Here are several screenshots.

[Bug Report Thread]

I found a few references to version 1.01 on the web, but have not been able to locate the files. If you could send the zip of bB1.01 to me, that would be greatly appreciated !!

[Bug Report Thread]

I'm using 1.0 so perhaps that is the issue. I found a link for 1.1 beta... is 1.01 still available? If so, please provide a link, and I try that. On..Goto works fine with 1.0, and I can transfer control to that label with the On..Goto without any issues. Appreciate the quick response!
