问题描述
我正在使用cocos2d-iphone + Box2d引擎,在Box2d中有一个简单的调用来创建主体:
I am using the cocos2d-iphone + Box2d engine, I have a simple call in Box2d to create a body:
b2Body *crateBody = world->CreateBody(&crateBodyDef);
然后我通过以下方式打印新增加的身体计数变量:
Then I am printing the newly incremented body count variable through:
CCLOG(@"There are %0.0f bodies in the world.", world->GetBodyCount());
但是, GetBodyCount()
始终返回 0
?我知道主体计数变量正在递增,因为当我调试并进入 CreateBody(..)
m_BodyCount
时,递增,检查器将分别返回 1
。我不明白使用 world-> GetBodyCount()
仅运行 return m_BodyCount
怎么会失败并返回0?
However, GetBodyCount()
always returns 0
? I know the body count variable is being incremented, as when I debug and step into CreateBody(..)
m_BodyCount
is incrementing, and my inspector returns 1
respectfully. I do not understand how with world->GetBodyCount()
simply running a return m_BodyCount
could this be failing and returning 0?
希望有人可以帮忙!
干杯。
Hope somebody can help!Cheers.

推荐答案
是 GetBodyCount ()
返回整数?如果是这样,则应在格式字符串中使用%d。
Is GetBodyCount()
returning an int? If so, you should use %d in the format string.
