我有一个问题,一旦热气球到达地面,就会出现黑色背景。
// a switch case based on state with appropriate calls
switch (state) {
// scene 1
case 1:
drawBackground1(); // the first background to appear
drawSlogan1(); // display the first slogan
break;
// scene 2
case 2:
drawBackground2(); // the second background to appear
drawSlogan2(); // display the second slogan
break;
// scene 3
case 3:
drawBackground1(); // the third background to appear
drawSlogan3(); // display the last slogan
break;
}
我在这里显示这段代码是因为这是我唯一更改的代码,它使黑色背景出现。
最佳答案
当气球到达最终位置时,state
为 0。如果 state == 0
也必须绘制背景:
switch (state) {
case 0:
drawBackground1(); // the third background to appear
break;
case 1:
drawBackground1(); // the first background to appear
drawSlogan1(); // display the first slogan
break;
case 2:
drawBackground2(); // the second background to appear
drawSlogan2(); // display the second slogan
break;
case 3:
drawBackground1(); // the third background to appear
drawSlogan3(); // display the last slogan
break;
}
