发生了一些非常奇怪的事情:当我调用foo(100 * 1.0f)时,沿着该行的某个地方变为0.要验证我在foo()上放置一个断点,它确实为零,它确实被调用了100 * 1.0F。代码在Obj-C ++中。
这是XCode的GDB前端中的调用函数,如您所见,score * scoreMultiplier为100。 Calling Function http://img341.imageshack.us/img341/1109/screenshot20100502at135.png
void JNPP1PGameController::addScoreToPlayer(NSInteger score) {
if(!gameOver){
JNLogString(@"Adding score(%d*%f) to player", score, scoreMultiplier);
[player addScore: score*scoreMultiplier];
[wrapper setShouldNotify];
[wrapper notify];
} else {
JNLogString(@"Not adding score(%d*%f) because GAME IS OVAR", score, scoreMultiplier);
}
}
这是XCode的GDB前端中的被调用函数,这里_score为0。 Called Function http://img156.imageshack.us/img156/1109/screenshot20100502at135.png
- (void) addScore:(NSInteger) _score {
score += _score;
JNLogString(@"Player can has %d points.. HURRAY!!!", score);
}
答案 0 :(得分:0)
通过将调用代码更改为:
来修复代码void JNPP1PGameController::addScoreToPlayer(NSInteger score) {
if(!gameOver){
JNLogString(@"Adding score(%d*%f) to player", score, scoreMultiplier);
NSInteger _score = score*scoreMultiplier;
JNLogString(@"This is the case: %d", _score);
[player addScore: _score];
[wrapper setShouldNotify];
[wrapper notify];
} else {
JNLogString(@"Not adding score(%d*%f) because GAME IS OVAR", score, scoreMultiplier);
}
}
我认为现在出现了一个未定义的错误(我得到了一个“找不到方法”警告)参数类型。
