Because you are annoying beyond reason. Your insistence made me lose all interest in DMG development before I even got through the ZGB tutorial, and I've blocked your email address ever since. I won't tolerate anymore of your petulance, both because I'm busy with my own stuff and because I just don't have to. I've already helped you out beyond what I think I should have, but you keep on punching walls, trying to program the Game Boy while not even knowing how to write basic code in the first place. I won't submit to any more of your pestering.

I know how hard it is to moderate a small community, in which you have to value each and every member - especially the eager ones. I know because I've been there, moderating a Doom forum which never grew beyond 50 members for nearly a decade. But if it was up to me, I'd ban your ass the instant I got wind that you were harassing other users and making death threats to them out on Skype and YouTube.

@everyone else: pardon me for bumping here whilst not contributing to the topic. I guarantee it won't happen again.

Re: ZGB, a little engine for the Game Boy

Greetings all,

I am fairly new to the dev scene and just wanted to say hello.  I'm very excited to try out this engine for my own projects (as terrible as they are).  A big thanks to everyone who has been helping make this engine something very special, especially Zalo!  Hopefully I am able to put something together between my university classes.  Thanks again!

Sorry, that is not posible yet.  Sprites will respawn again when moving the scroll back to the respawn position

Re: ZGB, a little engine for the Game Boy

Please kindly make this one easy for me

Is there a way to pause the game by pressing select and unpause by pressing select again ?

Then it shows the text pause. If I get a answer I would be very thankful

many thanks

Re: ZGB, a little engine for the Game Boy

Create a variable called "paused". This should work because I used it in Ten Pest.

Code:

    if ((key & (J_START)) && (paused==0)) paused=2;     
    if ((!(key & (J_START))) && (paused==2)) paused=1, gotoxy(7,16), printf("PAUSE");

    if ((key & (J_START)) && (paused==1)) paused=3;     
    if ((!(key & (J_START))) && (paused==3)) paused=0, gotoxy(7,16), printf("      ");

I sent you a email please reply to me if you can and do Ten Pest uses the ZGB engine

Re: ZGB, a little engine for the Game Boy

Hopefully this will get people's attention as it is very helpful. There is a way to compile directly from notepad ++ using ZGB

Code:

CMD /V /K SET n=$(CURRENT_DIRECTORY)&&SET "s=!n:ZGB-Template="^&SET e=!&&CD !s!ZGB-Template&& build.bat

Just hit ‘F5’ paste the above command and then save it as ‘Build’


Code:

CMD /V /K SET n=$(CURRENT_DIRECTORY)&&SET "s=!n:ZGB-Template="^&SET e=!&&CD !s!ZGB-Template&& build_Debug.bat

Just hit ‘F5’ paste the above command and then save it as ‘Build Debug’


Code:

CMD /V /K SET n=$(CURRENT_DIRECTORY)&&SET "s=!n:ZGB-Template="^&SET e=!&&CD !s!ZGB-Template&& build_Color.bat

Just hit ‘F5’ paste the above command and then save it as ‘Build Color'


Code:

CMD /V /K SET n=$(CURRENT_DIRECTORY)&&SET "s=!n:ZGB-Template="^&SET e=!&&CD !s!ZGB-Template&& build_DebugColor.bat

Just hit ‘F5’ paste the above command and then save it as ‘Build Colour Debug’
     

Code:

CMD /V /K SET n=$(CURRENT_DIRECTORY)&&SET "s=!n:ZGB-Template="^&SET e=!&&CD !s!ZGB-Template&& clean.bat

Just hit ‘F5’ paste the above command and then save it as ‘Clean’

So what will happen is any file from the ZGB template folder will scan for those bat files and then run it. If you have multiple ZGB Template folders then the file you got open from that directory will build using the bat file from there

Re: ZGB, a little engine for the Game Boy

Oh wow, this looks incredible! yikes

Is this CC-licensed? Am I able to use this in a game I'm developing for GameBoy that I potentially might sell on an actual cartridge?

Re: ZGB, a little engine for the Game Boy

Sure you can you are even welcome to take this code while you are at it.
https://github.com/Zal0/bitbitjam2017 and remove all his name and write yours. put it as a cartridge and make heaps $$$ all to yourself

Re: ZGB, a little engine for the Game Boy

@npzman: I don't think Zal0 will be happy if someone takes its code, remove all mentions to him and sell it as is. I think you should learn to respect the work done by other people. But may be I'm wrong.

@esotericsean: you should ask to Zal0 if he doesn't go on this post, there is no licence on his github, but I think you will can if you talk to him.
