Here's the whole method... it is being called from within a view's drawRect
method...
- (void) showDiceAtX: (float) x Y: (float) y {
NSRect imageRect1, imageRect2;
NSImage *die1 = nil, *die2 = nil;
iDie = iRand(1, 6);
switch (iDie) {
case 1:
die1 = [NSImage imageNamed: @"1 Die"];
break;
case 2:
die1 = [NSImage imageNamed: @"2 Die"];
break;
case 3:
die1 = [NSImage imageNamed: @"3 Die"];
break;
case 4:
die1 = [NSImage imageNamed: @"4 Die"];
break;
case 5:
die1 = [NSImage imageNamed: @"5 Die"];
break;
case 6:
die1 = [NSImage imageNamed: @"6 Die"];
}
jDie = iRand(1, 6);
switch (jDie) {
case 1:
die2 = [NSImage imageNamed: @"1 Die"];
break;
case 2:
die2 = [NSImage imageNamed: @"2 Die"];
break;
case 3:
die2 = [NSImage imageNamed: @"3 Die"];
break;
case 4:
die2 = [NSImage imageNamed: @"4 Die"];
break;
case 5:
die2 = [NSImage imageNamed: @"5 Die"];
break;
case 6:
die2 = [NSImage imageNamed: @"6 Die"];
}
imageRect1.origin = imageRect2.origin = NSZeroPoint;
imageRect1.size = [die1 size];
imageRect2.size = [die2 size];
/*
* NSRect NSMakeRect(float x, float y, float w, float h)
*
* Creates an NSRect having the specified origin of [x, y] and size of
[w, h]
*/
iDieDrawRect = NSMakeRect(x - imageRect1.size.width - 2, y,
imageRect1.size.width, imageRect1.size.height);
jDieDrawRect = NSMakeRect(x + 2, y, imageRect2.size.width,
imageRect2.size.height);
while (![self lockFocusIfCanDraw]) RELQ(.1);
[[NSColor whiteColor] set];
[die1 drawInRect: iDieDrawRect
fromRect: imageRect1
operation: NSCompositeSourceOver
fraction: 1.0];
[die2 drawInRect: jDieDrawRect
fromRect: imageRect2
operation: NSCompositeSourceOver
fraction: 1.0];
[self unlockFocus];
[[self window] flushWindow];
}
without the lockFocus the images never show.
