让精灵在cocos 2d中跳跃

Question

我是cocos2d的初学者，而且我正在使我的精灵在垂直方向上跳跃的问题，所以请任何人帮助我摆脱这种情况...... 这是我的代码......

-(id) init
{
    if( (self=[super init])) {
        // enable touches
        self.isTouchEnabled = YES;

        // enable accelerometer
        self.isAccelerometerEnabled = YES;

        ManStanding = [CCSprite spriteWithFile:@"ManStanding.png"];
        [ManStanding setPosition:ccp(40,0)];
        [self addChild:ManStanding];
    }
    return self;
}

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

    id jump = [CCJumpBy actionWithDuration:1 position:ccp(100, 0)
                                   height:50 jumps:1];
    [ManStanding runAction:jump];
}

任何人都可以指导我做错了什么.. 提前谢谢......

Answer 1

您在x轴上设置100像素跳转，在y轴上设置0。请尝试下面的代码

    id jump_Up = [CCJumpBy actionWithDuration:1.0f position:ccp(0, 200)
                                    height:50 jumps:1];
    id jump_Down = [CCJumpBy actionWithDuration:0.7f position:ccp(0,-200)
                                    height:50 jumps:1];

    id seq = [CCSequence actions:jump_Up,jump_Down, nil];

    [sprite runAction:seq];

Answer 2

id uppar = [CCJumpBy actionWithDuration:0.9f position:ccp(100,0) height:0 jumps:1];
id down = [CCJumpBy actionWithDuration:0.9f position:ccp(-100,0) height:0 jumps:1];
id seq = [CCSequence actions:uppar,down, nil];
[user1 runAction:seq];
