Re: Some SDL Issues
1) I'm not sure how best to describe this, and I can't seem to catch it to take a screenshot of it, but when the sprites move across the screen, sometimes the rows of pixels are out of alignment, and it flickers a bit, sort of like scan lines are being drawn over it. Does anybody know what causes t...

I never realized from watching gameplay videos how similar this is to garrys mod.

Re: Resource managing in OpenGL
First of, there is no such thing as CPU space. CPU usage is measured over time and 50% CPU usage means that 50% of the time the CPU spends executing anything is spent on your program. So I don't think this has anything to do with OpenGL or something that's wrong with your program. You're probably ju...

Re: segfault error; help please?
The 'controller' pointer has probably not been initialized. But to sidestep that problem you could just have this: class inputClass { private: SDL_Joystick* joystick; myController controller; // value instead of pointer public: inputClass(); ~inputClass(); void updateStates(); myController* getState...

I don't see what you're saying. What's not portable about it?

Re: Something I bet you didnt know you could do with pointers #2
i mean im not trying to say anything bad. but malloc(n) is such a bad programming practice. you would lose a job programming like that. (type*)malloc(n*sizeof(type)); I think you should reread the example, because inside the swap function there's no information about the type. I do agree the n para...

Re: Loading Maps..
Here's a website on creating a dynamically allocated multidimensional array http://www.eskimo.com/~scs/cclass/int/sx9b.html < it's from the Guides & Resources Topic. The method described on that website could however be overkill. What I usually end up doing is creating a flat array like this: in...

Re: Are you a programmer at heart?
I thought it was a pretty cool game. It even supports recursive functions 8-). Didn't use recursion to complete a level though. i dont thing it supports recursion, recursive functions can stop. if you did something recursive in that it be an infinite loop. (i think, i didnt look at it indepth) Hmm,...

Re: BITWISE challenge
did you know that it fliped the bits before you wrote the program. and do you know what 2's compliment it? how about little and big endian? these are all very interesting fundamental concepts of CS Yes, I didn't just randomly try operators to see which one worked. 2's complement is the way negative...

Re: BITWISE challenge
It's the 'One's Complement Operator' and it flips all the bits in the integer, not sure what happens with negative numbers though. So I wrote a little program to find out what is does with negative numbers. And it really does flip every bit: one's complement of -3: ~11111111111111111111111111111101 ...

Re: BITWISE challenge
Like this?
Code: Select all
int math_floor(int value)
{
return value & ~1;
}
int math_ceil(int value)
{
return (value & ~1) + 1;
}

Re: Something that might help you.
True, and that's why I said it had 'basically' the same functionality and not 'exactly' the same functionality.
