1 Spring wind contain Yemei
In this lantern festival , It's boring at home , Never played King , And I prefer to stand in the perspective of a person who makes games , Play psychological warfare , Advance the code to attract players . Let's give you an example , in real life , It's hard to get real-time feedback for your hard work , But the king will kill five , Basically, the whole world is proud of you , This wave of psychological design is great ; also , When playing King , You can't see time in the game , Let you have no concept of time , In fact, the time setting is just a matter of a few lines of code . There are also many logical thinking in designing games , Not one by one .
I remember when I was a child, I was fascinated by playing a game of Plants vs. Zombies , I don't want to eat every day . For the sake of my boredom today , First read a poem by Emperor Yang of the Sui Dynasty , Calm down and get another Plants vs. zombies , Just use Matlab Achieve it. .
《 On New Year's Eve, lights are built on the thoroughfare and the south tower rises at night 》
——( Sui Dynasty ) Sui Yangdi
The Dharma wheel turns in the sky , Brahma came from heaven ;
A thousand lights from a lamp tree , Seven flowers bloom .
The shadow of the moon doubts the flowing water , Spring breeze contains night plum ;
Burn the golden ground , Clock sends glass platform .
2 Philosophies brought by the joy of games
What is meant by “ happy ”？ What is the “ Happiness ”？ This is a question that few people can answer . It's strange that , Everyone's daily behavior tendency is locked in this phantom goal without exception , As if it were right in front of you , As if it speaks for itself .
The ancients said ：“ Contented people are always happy ”,—— This will probably become “ Happy ” A kind of self mockery of people who can't get up —— Modern economists have also compiled a formula that seems to be able to calculate accurately ：
happy = earnings / desire , It means , The higher the income, the happier , If income is limited , That can only be reduced “ Denominator of desire ” To improve the “ Happiness value ” 了 , However , According to my observation , Those who squash their desires , Own happiness “ Probably as dry as boredom .
Strictly speaking , The psychological activity of happiness is nothing more than the sum of a series of low intelligence emotional activities , Its control center is located in the thalamic reticular system below the higher cortex of the brain . therefore , Everyone's normal psychology must be maintained in a painless and joyless “ Boring baseline ”.（ Give the frog's sciatic nerve strong 、 The weak stimulation experiment is a powerful proof .）
