记忆游戏-使2张卡在X时间后消失

Question

I wanted to make a "memories" or "find pairs" game for Java, just to start with a basic game before starting something more difficult. My game works very well, but I just have 1 big problem. I don't really know how to hide the 2 images x seconds after the user clicks on the second one.

This is what is done:

1. The game is created with 4x4 buttons in a array
2. The values of the cards are distributed (name, position, icon)
3. The user then clicks on the first card, which shows up immediately
4. The user clicks on the second one, if the first is equal to the second one then disable the 2, if not then re-hide the 2.

But I don't know how I can make the program show the second card and then after x seconds hide the 2...

How can I solve this?

Answer 1

Depending on what framework you are using, there should be a timer utility available to you.

For instance, if you are using Swing, then you should be able to use javax.swing.Timer as suggested in the above comments. Follow this link for a simple Swing Timer tutorial . As they say on that page, swing timers can be used in one of two ways and one of those ways is:

To perform a task once, after a delay

This sounds like exactly what you are trying to achieve.

You could also try a library like Joda Time which has lots of features and options.

您应该创建匹配函数和另一个不匹配函数，并且在不匹配函数内部，可以使用setTimeout并在选择它们时以及在一定时间后和它们不匹配时给两张卡片分类（翻转），请移除此翻转类。
