所以游戏基本上都是这样的，每当火焰与冰淇淋接触时，我都希望在屏幕上画出不同的冰淇淋。较小的一个类似于“融化”的外观。但是，每当冰淇淋和火焰发生碰撞时，游戏就会在没有结束时结束。
这是渲染iceCream的代码
private void renderIceCream(Painter g) {
if (iceCream3) {
g.drawImage(Assets.iceCream3, (int) iceCream.getX(), (int) iceCream.getY(), ICECREAM_WIDTH, IC3_HEIGHT);
if (Rect.intersects(iceCream.getRect(), fire.getRect())) {
iceCream3 = false;
iceCream2 = true;
}
}
if (iceCream2) {
g.drawImage(Assets.iceCream2, (int) iceCream.getX(), (int) iceCream.getY() + 25, ICECREAM_WIDTH, IC2_HEIGHT);
//
if (Rect.intersects(iceCream.getRect(), fire.getRect())) {
iceCream2 = false;
iceCream1 = true;
}
}
if (iceCream1) {
g.drawImage(Assets.iceCream1, (int) iceCream.getX(), (int) iceCream.getY() + 50, ICECREAM_WIDTH, IC1_HEIGHT);
if (Rect.intersects(iceCream.getRect(), fire.getRect())) {
iceCream1 = false;
iceCream.melted();
}
}
}

this.width=width;
this.height=height;

this.x = x;
this.y = y;
this.width = width;

rect = new Rect();
isFrozen = true;
}
public void update(float delta) {
if (!isGrounded()) {
velY += ACCEL_GRAVITY * delta;
} else {
y = 406 - height;
velY = 0;
}
y += velY * delta;
updateRect();
}
public void jump(){
y -= 10;
velY = JUMP_VELOCITY;
updateRect();
}
public boolean isFrozen(){
return isFrozen;
}
public void melted(){
isFrozen = false;
}
public float getX() {
return x;
}
public float getY() {
return y;
}
public void updateRect() {
rect.set((int) x, (int) y, (int) x + width, (int) y + height);
}
public Rect getRect(){

}
}
答案 0 :(得分：0)
我认为可以通过添加这两个else语句来解决问题：
private void renderIceCream(Painter g) {
if (iceCream3) {
...
}
else if (iceCream2) {
...
}
else if (iceCream1) {
...
}
}
如果没有else语句，当iceCream3为真且存在冲突时，iceCream2变为true，Java进入下一个if语句，其中iceCream1变为true。使用else语句，这不会发生。如果您之后通过调用fire.reset()移开了火，那么您的代码现在应该可以正常工作。
