Problems with level loading...

[CyberCarsten]

Hi!
I am programming a breakout game, but cant seem to get the leve loading working....

loading code:

int LoadLevel(int level){
	char File ="level.dat";
	char s[32];

	Num = fscanf(File, " %s %d %d ",  &level_x, &level_y);
	if(Num != 2){
    return false;
}
return(1) ;
}

File format

<x_coord> <y_coord>

Level file:

1 10
5 20
10 30
15 40
20 45
25 50
30 55
35 60
40 65
45 70
50 75
55 80
60 90
65 100
70 110
75 120
80 130
85 140
90 150
95 160
100 170
105 180
110 190
115 200
120 210

I get the following errors:
:\Game Programming Projects\CrazyBalls 2\main.cpp(212) : error C2440: 'initializing' : cannot convert from 'char [10]' to 'char'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast

Hope you can help me correct my errors....

int LoadLevel(int level) {
	char File ="level.dat";
	char s[32];

	Num = fscanf(File, " %s %d %d ",  &level_x, &level_y);
	if(Num != 2) {
		return false;
	}
	return(1) ;
}

Ok, let's see.
char File = "level.dat";
should be
const char *File = "level.dat";

Then you have to open the file.
FILE *fIn = fopen(File, "rt");

This handle you can pass to fscanf.
Num = fscanf(fIn, " %s %d %d ", &level_x, &level_y);

And the %s you pass is DEADLY!
It should be
Num = fscanf(fIn, "%d %d ", &level_x, &level_y);

Finally, you're mixing data types.
return false;
...
return 1;

The function is declared to return int, so don't return the bool value false, return 0.

thank you

This should probably be in the C++ forum.

Maybe, but it's still a game issue.

Its formatted file IO. It could be anything =).
