A tip for writing procedurally complex code like that is to employ comment-first coding which allows you to understand exactly what it is you need to do before you even write it. This code was obviously written "as you went along". Start fresh, write a bunch of pseudocode in comments, then all you should have to do is fill in the logic under the comments. | ||

![[image loading]](http://i80.photobucket.com/albums/j175/darkness5723/proj2working.png) hey if anyone is curious.. i fixed it, 10 minutes after project was due. sonovbob found the broken code like 10 posts back i just missed it lol. it was the comparison == , and i was using =. fucking stupid c++ compiler should catch that lol. anyway... thats what it does. | ||

It's not a compile error so it shouldn't catch that. Doing assignment within a conditional is a pretty normal thing to do. If you want some help from the compiler I believe there are certain warning flags you can set that will give a warning if you do not parenthesize the assignment within the conditional. if( something = newSomething) ... Could be set up to give you a compiler warning which would then go away if it was changed to if( (something = newSomething) ) ... Can't remember the exact flag you need but I'm sure you can google it easily enough. | ||

yes.. yes.. he did. as to the assignment within a conditional, yeah i know its a legal operation i was just mad that i didnt catch it lol. I normally don't mess that up so I don't think to check it. also, when would you need to do an assignment within a conditional? i cant really find a use for that.. | ||

Recursion depth 534 o.O Didn't read the code, though that seems like a lot of recursion. Prolly would've done it by recursively calling hasBlobProperty() and having the outer layer go through every array position that hasn't already been marked as having a part of a blob there, and the second layer would keep track of the # of blobs. But apparently your method works so it's all good =) | ||

Is C++ hard to learn? | ||

EDIT: Although, if I recall correctly C# can execute up to 40 times slower than C++, and the JVM means Java is slower as well (but you would learn the details yourself in a Java course). Of course, efficiency usually won't matter too much... though I think most games are not made with Java/C# (WoW for instance is written in C++), but you would use a lot of C# and Java in other programming jobs. | ||

I don't think it's ever a necessity (could be wrong), it's just a nice convenience for a lot of things. | ||

Regarding the assignment inside a conditional, here's random example code where it might be used: char[] str = "Hello TeamLiquid!" char c; for (int i = 0; (c=str[i]) != 0; i++) { printf("Letter: %c", c); } From a stylistic point of view, I don't think it's usually a particularly good idea, but it would be inconsistent to treat the assignment differently just because it was placed inside a conditional statement. | ||
