Tiles are weird
Post: #1
im making a tile type thing to test some stuff and its terrible at working correctly
since the source code isnt all that long here it is
header file
here is the main file
what that does is when i click one of the little squares say the bottom left it comes up with x = 1 y = 1, instead of x = 0 y = 0 also the top and rightmost row and column dont do anything, i stuck the exact same alert panel call right before the MouseInRect call to see if it was starting at 1 1 or 0 0
turns out it runs through all the positions correctly starting at 0 0 and ending at 9 9
so what is wrong with MouseInRect? is it biased aginst the NSRect array?
And why am i an evangelist, im pretty sure i havnt tryed to convert any of you to christians.. or gone on any cursades latly
since the source code isnt all that long here it is
header file
Code:
#import <Cocoa/Cocoa.h>
enum {HERO, NONE};
@interface gameView : NSView
{
NSImage *heroImage;
int board[10][10];
NSRect clickArea[10][10];
int xpoh, ypoh;
}
- (void)mouseLocationX:(int)x y:(int)y;
@endhere is the main file
Code:
#import "gameView.h"
@implementation gameView
- (id)initWithFrame:(NSRect)frameRect
{
if ((self = [super initWithFrame:frameRect]) != nil) {
// Add initialization code here
}
return self;
}
- (void)awakeFromNib
{
heroImage = [[NSImage imageNamed:@"hero.png"] retain];
int x, y = 0;
for (x = 0 ; x < 10 ; x++) {
for (y = 0 ; y < 10 ; y++) {
board[x][y] = NONE;
clickArea[x][y] = NSMakeRect(x*16,y*16,16,16);
[NSBezierPath strokeRect:clickArea[x][y]];
}
}
board[9][9] = HERO;
xpoh = ypoh = 9;
}
- (void)drawRect:(NSRect)rect
{
int w, k = 0;
for (w = 0 ; w < 10 ; w++) {
for (k = 0 ; k < 10 ; k++) {
[NSBezierPath strokeRect:clickArea[w][k]];
}
}
NSRect hero, modal;
hero.size = [heroImage size];
hero.origin = NSMakePoint(xpoh*16, ypoh*16);
modal.size = [heroImage size];
modal.origin = NSZeroPoint;
[heroImage drawInRect:hero fromRect:modal operation:NSCompositeSourceOver fraction:1];
}
- (void)mouseDown:(NSEvent *)event
{
NSPoint loc = [event locationInWindow];
int a, b = 0;
for (a = 0 ; a < 10 ; a++) {
for (b = 0 ; b < 10 ; b++) {
if (NSMouseInRect(loc, clickArea[a][b], NO) == YES) {
[self mouseLocationX:a y:b];
}
}
}
}
- (void)mouseLocationX:(int)x y:(int)y
{
NSRunAlertPanel(@"CLICKED!", @"x = %d y = %d", @"OK", nil, nil,x,y);
}

Your coordinates are wrong. Remember that in Cocoa (0, 0) is located in the bottom left corner, and not in top left corner.
With this said, try switching your x and y variables...
