ios - 在 CCLabelTTF 上设置随机 CCColor

Question

我需要在这种颜色切换之间获得一种随机颜色，以便将其放在标签上。

                label1.color = ccBLUE;

                label1.color  = ccRED;

                label1.color  = ccGREEN;

                label1.color = ccBLACK;

                label1.color = ccYELLOW;

                truckName.color = ccWHITE;

                [label1 setColor:ccc3(160,32,240)];

                label1.color = ccORANGE;

你能帮我做吗？我从未使用过随机数

Answer 1

完全随机颜色：

            [label1 setColor:ccc3(rand()%255, rand()%255, rand()%255)];

您还可以设置一些限制：

            [label1 setColor:ccc3(100+rand()%155, 150+rand()%105, 200+rand()%55)];

int randColor = arc4random()%5;
switch(randColor)
{
    case 0: default:
        label1.color = ccBLUE;
        break;
    case 1:
        label1.color  = ccRED;
        break;
    case 2:
        label1.color  = ccGREEN;
        break;
    case 3:
        label1.color = ccBLACK;
        break;
    case 4:
        label1.color = ccYELLOW;
        break;
}
