获取当前的触摸位置随时在Cocos2d的iPhone [英] Get current touch location anytime in Cocos2d for iPhone

问题描述

我一直使用以下方法来检测触摸何时开始以及位置是什么：

I have been using the following method to detect when a touch began and what the location is:

-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event{

    CGPoint touchLocation = [touch locationInView: [touch view]];
    touchLocation = [[CCDirector sharedDirector] convertToGL:touchLocation];

    touchLocation = [self convertToNodeSpace:touchLocation];

    return YES;
}

但我也想知道如何获取当前位置如果我的手指仍然在屏幕上，请触摸。任何人知道如何？感谢。

But I would also like to know how to get the current location anytime of my touch if my finger is still on the screen. Anyone know how? Thanks.

EDIT

bit我认为，但这是我做的：

I'll post this as an answer in a bit I think, but this is what I did:

我只是继续转换一个变量在一个ccTime方法定义之外的所有我的方法：

I just kept converting a variable in a ccTime method defined outside of all my methods:

- (void)update:(ccTime)dt {
heroMoveEndLoc = [self convertToNodeSpace:heroMoveEndLoc];
}

推荐答案

- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    UITouch *touch = [touches anyObject];
    CGPoint location = [touch locationInView:[touch view]];
    location = [[CCDirector sharedDirector] convertToGL:location];
    x_point = location.x;
    y_point  = location.y;
    [self schedule:@selector(updateFunction)];
}

-(void)updateFunction
{
    NSLog(@"Location is %0.02f %0.02f",x_point,y_point);
}
- (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    [self unschedule:@selector(updateFunction)];

}
