Hi people, I'm working on my next game already. I'm trying to use Andre's strategy in Underworld and not use hard coded data, but use an external file that contains the level data. Unfortunately, this is giving me pain. I am using my preferred file loading functions, the mmio type. I am also using introductory C++/OOP, as I'm using classes. Here's my code for loading the array with data and stuffing it into the class function:
switch(choice)
{
case '2':
for(y=0; y{
for(x=0; x{
*array=getche();
array++;
}
*array='\r';
array++;
printf("\n");
} // end for
level.WriteNewLevel(array);
break;
} // end switch

The variable "array" is a character pointer with all the space needed allocated. Here's the class function, WriteNewLevel():

void CLevelDesc::WriteNewLevel(char *data)
{
// go to the end of the file
mmioSeek(file, 0, SEEK_END);

// Write the data to file
mmioWrite(file,data,(CELL_X+1)*(CELL_Y));
}

The problem is that my file now holds 315 letters of garbage where it should hold 320 letters of whatever I specify (right now I'm trying to use just one character that is solid throughout the file.) Could someone help me?

That's how you do it, but that's just the opinion of a MADMAN!!! BWAHAHAAHAHA! :D :D :D

OK, stupid math error, it was SUPPOSED to be 315 bytes but I made a stupid error. But that still doesn't explain WHY its gives out garbage.

OK, here's the deal. I got it working pretty good, but I modified it a bit. First I used the old C file routines, like fopen(). Second, I cleaned up the code and I modified it so that it doesn't use pointers but deals with the arrays themselves. Finally, I got it to work except for a slight matter. Here's the main() function:

code:

---

// Main function
void main(void)
{
	char choice=0;
	char x,y;
	char array[316];
	char newline=0;
	CLevelDesc level;
	level.LoadLevelFile();
	// Now get the user's input
	while(choice!='3')
	{
		// Now get what the heck the user wants to do
		printf("\nEnter 1 for reading, 2 for writing, and 3 to quit.\n");
		choice=getche();
		printf("\n");
		switch(choice)
		{
		case '2':
			for(y=0; y			{
				newline++;
				array[((y*CELL_X)+x)+newline-1]='\n';
				printf("\n");
				for(x=0; x				{
					array[((y*CELL_X)+x)+newline-1]=getche();
				}
			} // end for
			array[315]='\n';
			level.WriteNewLevel(array);
			break;
		} // end switch
	}// end while
	level.UnloadFile();
} // end main()

It works pretty well, except on the first line instead of getting a newline two of the lines. Here is the first line

ddddddddddddddddddddÖdddddddddddddddddddd

Are you getting the ...dddÖddd... effect on every line, or just the first?

Can't really see what your code is doing, because it's trying to parse it for html... look at your for loops

When you're showing code in your posts, a good suggestion is:
