英文:
Is it possible for a method to stop another method from being called if a condition is true?
问题
我被分配了一个任务，需要编辑一个游戏并添加不同的元素，其中之一是在与对象交互时恢复玩家生命值，我已经完成了这部分。
接下来的步骤是在玩家生命值达到最大值（100）时停止此功能。
我的想法是创建一个带有条件的方法（如果条件为真，则停止我的生命增加方法的运行/调用）。
示例：
private void checkMaxLife() {
if (playerLife==100) {
//停止 addLife 方法的运行
}
}
这是否可行，语法是什么？
编辑：
这是修复方法，在碰撞方法中添加 playerLife < 100。
private void foodAddLife() {
//检查食物碰撞
for (int i = 0; i < food.length; ++i) {
if (playerLife < 100 && food[i].getX() == player.getX() && food[i].getY() == player.getY()) {
//发生碰撞
++playerLife;
}
}
}
英文:
I've been given an assignment to edit a game and add different elements to it, one was the ability to restore player life when interacting with an object which I have completed.
The next step is to stop this from working when the players life is max (100).
My idea then was to create a method with a condition (and if it is true, stop my life adding method from working / being called.)
Example:
private void checkMaxLife() {
if (playerLife==100) {
//Stop method addLife from working
}
}
Would this be possible and what is the syntax?
EDIT:
This was the fix, added playerLife < 100 to the collision method instead.
private void foodAddLife() {
//Check food collisions
for (int i = 0; i < food.length; ++i) {
if (playerLife < 100 && food[i].getX() == player.getX() && food[i].getY() == player.getY()) {
//We have a collision
++playerLife;
}
}

看起来你不需要 checkMaxLife，只需在方法 addLife 中使用属性 playerLife。
private void addLife() {
if (playerLife < 100) {
playerLife++; // 或者任何其他值
}
}
通过这两个方法，你可以看出其中一个是无用的。
private boolean isFullLife() {
return playerLife >= 100;
}
private void addLife() {
if (!isFullLife()) {
playerLife++; // 或者任何其他值
}
}
英文:
It seems you don't need checkMaxLife, just use the attribute playerLife in the method addLife
private void addLife() {
if (playerLife < 100) {
playerLife++; // or whatever value
}
}
With 2 methods, you see that one is useless
private boolean isFullLife() {
return playerLife >= 100;
}
private void addLife() {
if (!isFullLife()) {
playerLife++; // or whatever value
}
}

你只需在玩家生命值为MAX_VALUE时返回该函数。
private void addLife() {
if (playerLife >= 100)
return;
// 做你需要做的事情
}
英文:
You just return the function when player life is MAX_VALUE.
private void addLife() {
if(playerLife>=100)
return;
// Do Whatever you need to do
}
