... there is no longer any kind selection force that can be placed on us as a species that we can't remove via technology. Lol. Yeah, except for the primary "selection force" in evolutionary theory known in layman's terms as "death". Evolution is all about tracing changes in a p...

Yeah, I was looking at that. Can't wait to see it when he's done. In the mean time, I searched the FreeBasic.net forums and found info about a GUI debugger for FB called Insight. (See http://streetcds.co.uk/insight.html) Seems to be doing what I need for now.

In the windows task manager, right click on that 'Ntvdm' process, choose "Set Priority", and set to "BelowNormal". All your other windows apps should run much more smoothly.

I've been trying to set up RQ Debugger, but haven't had much success. I was just curious, for those of you that use FreeBasic, how do you debug? I'd love to be able to use something similar to the qbasic interpreter. Even just a link to information on the FreeBasic forums or any other helpful site w...

Fixing the flashing asteroids This won't be too tough since we know that the flashing problem occurs from clearing a character and then immediately re-drawing the same character in the same spot. If there's a way to prevent re-drawing the same character over itself, then we can remove the annoying ...

Here's the problem: 'Print Meteor LOCATE meteory, meteorx COLOR 0 PRINT "00" PRINT "00" with color 0 WILL make the asteroid disappear on the screen, but the ascii value for that position will still be for the "0" character. Just because you redrew the asteroid with colo...

Alright thats sorted now, thanks everyone. One last thing, I've made it so my Spaceship can't move through an asteroid or any "0". Anyway after It moves along ther screen the asteroid leaves behind an invisible trail o "0"'s. I thought I printed over them with nothing, but I can...

What do you mean by "the Palette"? Reading your post is slightly confusing, because at first you seem to be talking about the screen palette when you mention that screen 13 has 256 attributes, but then it seems like you switch to the actual screen pixel colors when you talk about saving t...

I've written a crude program that creates and plays videos in qbasic (no sound yet). I wanted to adjust for the cpu speed, so I created a SUB to gauge the computer's speed. The code determines the maximum frames per second the cpu can handle, the number of empty FOR/NEXT loops the computer can run i...

"The only other limit to be aware of is QBASIC's 160K limit on program AND code size. One buffer of sprites (252 sprites) will eat almost 64K, leaving you with less than 100K to put the rest of your code in! QuickBASIC and PowerBASIC users shouldn't have any problem though." (See http://w...

In the k$ = "d" code, change FOR y = 0 TO 11 to FOR y = 11 TO 0 STEP -1 In the k$ = "r" code, change FOR x = 0 TO 19 to FOR x = 19 TO 0 STEP -1 The reason for your problem on moving down and right is that you end up changing bits before you get a chance to scan them. BTW, if you'...

- Variables should not be named the same as functions or subs in FB to avoid potential conflict. (sometimes gives duplicate definition error) Ugh. That totally sucks. That alone makes me want to avoid rewriting my code for FB. Now that I double-check, I may be mistaken on that one. It's not listed ...

Conversion from QB to FB There are enough differences between FB and QB that it could take a good bit of updating before your code will run in FB. I downloaded the FBIde in addition to the FreeBASIC command line compiler which has a nice help module. ( http://www.freebasic.net/index.php/details?pag...

If you save your program in text format from the qb interpreter (Save As...->Select Format Txt), any text editor will be able to open the .bas file. Then you should be able to copy and paste your code into a forum post.

Thanks for the suggestions! Never got it to work in qb4.5, but after a couple hours of cleaning up the code to be compatible with FB, got it working.

To retrieve a web page in qbasic, you could make use of the wget.exe utility. (I believe it's a unix command that was ported to windows.) I was able to use it to create a program that downloads webpage information from a particular site (using wget) and then parses the page through OPEN and LINE INP...
