I think you should use combination of setting node.name property while creating crates and checking them in touchBegan: method.
Something like this:
SKSpriteNode *crate = [SKSpriteNode spriteNodeWithTexture:tex];
crate.name = @"crate";
And touchBegan: method:
.....
if ([touchedNode.name isEquelToString:@"crate"]){
// do something with that node
}
.....
Upd1:
Instead of writing this stuff:
if ((location.x > self.crate.frame.origin.x && location.x < self.crate.frame.origin.x + self.crate.frame.size.width) &&
(location.y > self.crate.frame.origin.y && location.y < self.crate.frame.origin.y + self.crate.frame.size.height)) {
[self.crate removeFromParent];
}
use:
if(CGRectContainsPoint(self.frame, touchPoint)){
// do something
}
Upd2:
Don't see in your code that you are setting userInteractionEnabled = YES on crate nodes.
Upd3:
Here is an example:
//
// BGMyScene.m
// Test1

// Created by AndrewShmig on 3/10/14.

//
#import "BGMyScene.h"
@implementation BGMyScene
- (id)initWithSize:(CGSize)size
{
if (self = [super initWithSize:size]) {
/* Setup your scene here */
self.backgroundColor = [SKColor colorWithRed:0.15
green:0.15
blue:0.3
alpha:1.0];
// first label
SKLabelNode *myLabel = [SKLabelNode labelNodeWithFontNamed:@"Chalkduster"];
// myLabel.userInteractionEnabled = YES;
myLabel.text = @"Hello, World!";
myLabel.fontSize = 30;
myLabel.position = CGPointMake(CGRectGetMidX(self.frame),
CGRectGetMidY(self.frame));
[self addChild:myLabel];
// second label
SKLabelNode *myLabel2 = [SKLabelNode labelNodeWithFontNamed:@"Chalkduster"];
// myLabel2.userInteractionEnabled = YES;
myLabel2.text = @"Hello, World!";
myLabel2.fontSize = 30;
myLabel2.position = CGPointMake(100, 100);
[self addChild:myLabel2];
}
return self;
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint touchLocation = [touch locationInNode:self];
SKNode *touchedNode = [self nodeAtPoint:touchLocation];
NSLog(@"touchLocation x: %f and y: %f", touchLocation.x, touchLocation.y);
if (touchedNode != self) {
NSLog(@"Removed from parent.");
[touchedNode removeFromParent];
}
}
- (void)update:(CFTimeInterval)currentTime
{
/* Called before each frame is rendered */
}
@end
You'll see following screen:
After tapping on "Hello, World!" labels they will be removed from parent node.
