processing - How can I track where my mouse goes and then if it goes beyond 400 pixels then print "you lose"?

Question

When my mouse goes beyond 400 pixels, it needs to print "you lose".

I have already tried the code below. Nothing happens

void setup() {
   size(800, 600);
   if (mouseX > 400) {
     print("game over");
   }
}   

Nothing happens.

该setup()功能只运行一次，就在程序第一次启动时。

如果您希望您的代码继续运行，请考虑将其放入draw()函数中，该函数每秒运行 60 次。

void setup() {
   size(800, 600);
}

void draw() {
   if (mouseX > 400) {
     print("game over");
   }
}
