In Topic: [SDL] Efficient collision detection?

25 September 2011 - 02:55 PM

Like what KDMiller3 said, you should create a function that will tell you if there is nothing taking space in the location you want to move to. So like if(areaAvailabe(<where player wants to move>)) returns true then proceed to move the player there. Though it's mostly the reverse of what you're doing now.

In Topic: "Game" crashes when instantiating object

Alright, just checked again, and it actually does not work. Must of grown delirious when programming late at night and assumed it was fixed.

Anyway, File.c_str() doesn't work, but just putting in "./image.png" does, even though File.c_str() should equal the same thing. Since SDL stops you from outputting to the console I'm going to work on writing the strings to files like Ectara said.

OnLoad() (which is a part of CSurface) is declared as a static function. You put in a char array (or c-string as I think they're called) and then it returns a pointer to a surface. What's odd is that it seems to still return a not null value when it fails to load the surface.

EDIT: Ok, it's working again. I just made a stupid error that gave me some weird results. I'm pretty strung out right now though, so I'll work on what I want for awhile before I post another question here. Thanks again everyone.


In Topic: "Game" crashes when instantiating object

I edited the OP stating that I fixed it by using File.assign() instead of File=. Though I guess if you want to clarify:

std::string File

function(std::string n){File=n;}

The function is then called likeso:

function("name");

Why would File=n not work yet File.assign(n) does?


In Topic: Multiple classes in the same .h and .cpp files

23 September 2011 - 02:42 AM

Because I don't like switching through .h and .cpp files, I just put the headers and the code in the .h file. How bad of a practice is this?

For example


class a

{

private:

function();

};

a::function()

{

}



In Topic: "Game" crashes when instantiating object

Alright, I'm having another problem.

File is a std::string equal to "./image.png"

I use a function that takes a filename as a const char* and loads an image.

OnLoad(File.c_str()) fails to load the file

OnLoad("./image.png") works.

How do I convert File into a const char* that would work with this? (No I cannot change the function to take in a std::string instead)

Tell me if you need more information, I'm updating the OP to include code I believe is relevant.
