Yes, functions can call themselves, and yes, what you're asking is very possible. ⋅ Turn your sub into a function that returns an integer. ⋅ At the beginning of the function, declare a local integer, init that to zero. ⋅ At each recursive function call inside your recur...

Don't check equality for floating point values (i.e. single and double). That's just asking for trouble. Instead, test for numbers very close to your desired value, in a range, using inequality operators.

If you have a better answer then post it. But your response is pretty clueless to me. No seriously, next time you have a problem, you should copy-paste the code as is. Adapted versions can inadvertently introduce self-corrections, and then we're left wondering why the code sample works, but the cod...

Thanks for the replies. This code works, it is a little messy and not-so-optimal but does the work. So my guess is that FB likes to know the upper and lower bounds of the arrays (like its own descriptor is set)? Nope. It just means you screwed up with the first code sample, though I've got nothing ...

Electric fence will wrap around calls to malloc() and other related functions in C. -lefence is sufficient, but I've never tried it with FB. What it does is place "fence blocks" around every memory allocation, so it can tell when you're accessing stuff outside of where you should. Never tried valgri...

You are seeing the color problems, right? The order of the bytes in the screen buffer still need to be worked out. Maybe it would be nice if ScreenRes could allow you to tweak the byte order, say to just make it RRRRGGGGBBBB, instead of some 4-byte thing that the 24-bit screen defaults too. Yeah, I...

Very nice! Got it working after a few tweaks: 1. The forum [ code ] tags have changed SYSTEM into System and name= to Name in the Glade XML file. 2. In two places in the source, you refer to "drawingarea", but the widget is named "drawingarea1". 3. You haven't written the implementation of on_button...

Since those pointers have to maintained somehow, they need to go into a class or type. Knowing stuff about classes, but nothing about classes in FB, the following code is purely theoretical and should be fixed by somebody who knows what they're doing: '' UNTESTED THEORETICAL FB CODE ''*** Pseudo cla...

Replies: 6

Well, there's good news and there's bad news. The bad news is that AFAIK, once you turn to pointers, you lose FB's nice array information. To find out if you're at the end of an array, you'll need to use either a sentinel value, or define a wrapper type with a length. FB's pointers most closely mimi...

@Skyler: Timer resolution isn't 1 millisecond. It can vary anywhere between 5-50ms. Multiple sleeps would only multiply this resolution problem. LukeL's code works, is simpler to read and remember, and the timer resolution issue only applies once.

When playing Touhou, one thing I noticed was that some bullets would rotate as they moved. Instead of travelling in a straight line, they would have rotational velocity (maybe even rotational acceleration too.) Any plans for that?

Props for a cool idea. I've always loved scrolling shooters.
