Question

我是iphone开发游戏（也是新软件开发领域）的新手。我需要开发像Ninga，veg samurai和cut cut boom games这样的切割效果。我不知道怎么做。我不知道如何做到这一点。搜索很多，他们说只是找到距离和角度向量，然后将其应用到4x4矩阵...（或）他们说使用openGL来开发这样的函数......就像他们说的，我使用openGL绘制但是看起来不像那样。任何人都可以帮忙做到这一点....给出开发切割效果的示例代码....提前致谢....

这是我的绘图功能，方便您使用..... - （无效）平局 {

if([_points count] > 0)
{ 
    glDisable(GL_TEXTURE_2D);
    glDisableClientState(GL_COLOR_ARRAY);
    glDisableClientState(GL_TEXTURE_COORD_ARRAY);


    glEnable(GL_TEXTURE_2D);
    glEnableClientState(GL_COLOR_ARRAY);
    glEnableClientState(GL_TEXTURE_COORD_ARRAY);
    glEnable(GL_LINE_SMOOTH);
    glColor4f(20, 20, 20, 20); 


    for(int i=0;i<[_points count]-1;i++)

            ccDrawLine(p1.location,p2.location);

    }
    [super draw];
}

我的更新功能淡出了这一行 - （void）更新：（ccTime）dt { double now = [[NSDate date] timeIntervalSince1970];

if(lastTimeTrailRemoved == 0)
{
    lastTimeTrailRemoved = now;
    return;
}

if(((now - lastTimeTrailRemoved) > 0.03f) && ([_points count] > 0))
{
    NSLog(@"removing last point");
    [_points removeObjectAtIndex:0];
    [_points removeObjectAtIndex:1];
    [_points removeObjectAtIndex:2];
    [_points removeObjectAtIndex:3];

    lastTimeTrailRemoved = now;
}

}

Answer 1

查看代码，我看到了几个问题。我会退一步，开始更基本的。 “前沿”的问题在于它们通常由先进的人完成，可以创造新的，令人敬畏的东西，因此是最前沿的。我可以推荐一本关于游戏开发的书吗？ Apress: Beginning iPhone Games Development是一本很好的读物。

我需要开发切割效果，如水果忍者，与iphone中的武士游戏
