+Atarius Maximus Posted June 25, 2007 Share Posted June 25, 2007 (edited) I've had a few requests via private mail to help people out who are trying to learn bB, along with requests for code examples. I thought I'd post some very simple, short programs that demonstrate how to do some specific things in bB. I always learn best by looking at sample code... hopefully these will help someone out. I'd be happy to create additional examples if someone wants one. Here are some links to some good tutorials from other members: From CurtisP: Programming Tutorial From SeaGtGruff: Tutorial Session 1 | Tutorial Session 2 | Tutorial Session 3 Other downloads & links you'll want: Get the latest version of bB here. Get the latest version of Visual bB here. Get the latest verison of Stella here. Read the latest documentation here.

SeaGtGruff Posted November 3, 2007 Share Posted November 3, 2007 HI,.. sorry for my bad english. yes, i mean how to move a animated Sprite. Your English is fine. I was 98% certain that was what you meant, but my real reason for asking was because I wasn't at home when I was reading the posts, and that meant your question wouldn't show up under "View New Posts" when I did get home later. I wanted to post *something* in the thread so it would show up under "My Posts" when I got home, to remind myself that I intended to reply to you. I could have just posted something like "I'll check on it later," but instead I decided to ask for verification of what you wanted, just to be certain. So don't worry about your English!

SeaGtGruff Posted November 3, 2007 Share Posted November 3, 2007 Okay, here's a sample that combines "3_MoveASprite.bas" with "5_AnimateASprite.bas." I think perhaps the reason you were having trouble combining them is because they both use variable y, but they use y for two different things. There are two ways this new sample can be improved-- (1) animate the sprite only when it's being moved around with the joystick; and (2) have the sprite face in the opposite direction if it's being moved right-to-left. But those can be for later.

freehabitat Posted November 3, 2007 Share Posted November 3, 2007 Thanx, that helps a lot! what i still did not understand is your reply of the other question with going to other Levels (goto different Playfields if something happenes). anyway... in next time i´ll try to work with combinations of the samples in this tread. Its my problem that i do not exactly know how to use lot of different actions in on programm. i look forward to create new samples with your help, that would be very helpfull for the other new programmers here. for me it´s the best way to learn, looking at other peoples programs and putting out special events i like to use. thanx so far,..

yuppicide Posted July 23, 2008 Share Posted July 23, 2008 I looked at your animated playfield code. You have this: x=10 : rem Counter number - when to switch to frame 2 y=20 : rem Counter number - when to switch to frame 3 z=30 : rem Counter number - when to switch to frame 4 main COLUPF=28 COLUBK=0 b=b+1 if b>30 then b=0 if b=x then goto frame1 if b=y then goto frame2 if b=z then goto frame3 ETC, ETC Wouldn't it be better to just to this? main COLUPF=28 COLUBK=0 b=b+1 if b>30 then b=0 if b=10 then goto frame1 if b=20 then goto frame2 if b=30 then goto frame3 ETC, ETC I don't know if it saves you any ROM, but this way you're not wasting variables. 1 Quote Link to comment https://forums.atariage.com/topic/109288-code-snippets-samples-for-bb-beginners/#findComment-1557215 Share on other sites More sharing options...
SeaGtGruff Posted July 24, 2008 Share Posted July 24, 2008 I looked at your animated playfield code. You have this: The only reason I can think of for using variables is to make the code more reusable within the program-- for example, if you want to speed up or slow down the animation rate by changing the values in the variables. Otherwise, constants help save RAM (which-- on the Atari 2600-- is more important than saving ROM, since RAM is more precious than ROM).

Michael That is exactly why I did it - to allow for changing the animation rate. I suppose it wasn't necessary for the sample program, yuppicide's revision would work fine too.

yuppicide Posted July 31, 2008 Share Posted July 31, 2008 One thing we should do with the first post is make everything the same. Am I nitpicking? Unfortunately yes. Everything code snippet has two files with it. First one being .bas, and second being .bin. Except number 8. It's backwards. First is .bin. Not a big deal, but I couldn't find 8 to load in bB and I swore I downloaded it lol. Second, number 10 is named .bas.bin when every other one is .bin. Anyway, nice tutorials. I enjoyed them. I think there should be one for how to insert simple background music and one how to insert a sound effect. I'll be able to manage just fine I am sure, but still would be nice to read a tut. Thanks again for the tutorials! 1 Quote Link to comment https://forums.atariage.com/topic/109288-code-snippets-samples-for-bb-beginners/#findComment-1561198 Share on other sites More sharing options...

It's a sample program that shows how to make the 'light' sprite around your character to move around an invisible maze, just like the mazes in the original Adventure game.
