SKSpriteNode靶向
SKSpriteNode靶向
提问于 2015-02-17 12:56:35
所以现在我的代码显示了7张扑克牌。如果按下扑克牌，它将从playerCard数组中移除该卡并将其添加到playedCards数组中。问题是，是用SKNode在touchesBegan方法中移动卡片；
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
if ([node isKindOfClass:[CardSpriteNode class]]) {好吧，没问题，卡在上面。问题是，playerCards中剩下的所有其他卡现在都需要移动，也就是(收紧)，就像原来的那样。这是我关于他们之间距离的公式；
int cardsLaid = i * (cardDisplay.size.width / 3);所以我现在可以得到最初显示的卡片和被触摸的卡片，在它们之间形成一个很好的差距。
我需要做的是把卡片移回一个很好的间隙，在它们之间的一张牌被移动之后，
for (int i = 0; i < [playerCards count]; i++) {
int cardsLaid = i * (cardDisplay.size.width / 3);
CGPoint forPoint = CGPointMake((0.5 - (self.frame.size.width / 4)) + cardsLaid, 0.0);
playerCards[i] //Here I need to target each skspritenode.name for each playerCards
[??? runAction:[SKAction moveTo:forPoint duration:0.6]];
}因此，我需要用保存在playerCards MutableArray中的名称来针对每个MutableArray。然后，一旦我锁定了一个spritenode，我就需要将它移到???所在的位置。
这是我的整个touchesBegan方法，如果有帮助的话。
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
if ([node isKindOfClass:[CardSpriteNode class]]) {
int add = (int)[playerCards count] * (cardDisplay.size.width / 3);
CGPoint origPos = CGPointMake(-self.frame.size.width/2.8 + add, -218);
if ([cardsPlayed containsObject:node.name]) {
//Card is already played, return to original position and remove from array.
CGPoint point = origPos;
[node runAction:[SKAction moveTo:point duration:0.6]];
node.zPosition = zPosCount;
zPosCount += 1;
[cardsPlayed removeObject:node.name];
[playerCards addObject:node.name];
NSLog(@"this ran");
} else {
//Card is not already played, position to add card and add to array.
amountOfCardsLaid = (int)[cardsPlayed count] * (cardDisplay.size.width / 3);
CGPoint point = CGPointMake((0.5 - (self.frame.size.width / 4
)) + amountOfCardsLaid, 0.0);
[node runAction:[SKAction moveTo:point duration:0.6]];
node.zPosition = zPosCount;
zPosCount += 1;
[playerCards removeObject:node.name];
[cardsPlayed addObject:node.name];
for (int i = 0; i < [playerCards count]; i++) {
int cardsLaid = i * (cardDisplay.size.width / 3);
CGPoint forPoint = CGPointMake((0.5 - (self.frame.size.width / 4)) + cardsLaid, 0.0);
playerCards[i]
[??? runAction:[SKAction moveTo:forPoint duration:0.6]];
}
}
//Hide.Unhide buttons
if ([cardsPlayed count] == 0) {
if (addButton.hidden == FALSE) addButton.hidden = true;
if (cancelButton.hidden == FALSE) cancelButton.hidden = true;
} else {
if (addButton.hidden == TRUE) addButton.hidden = false;
if (cancelButton.hidden == TRUE) cancelButton.hidden = false;
}
}
}
我需要缩小的差距在底部的playerCards上

SKNode *tempNode = [self childNodeWithName:playerCards[i]];几天后。fml
