问题描述
我正在寻找一个明确的答案，也许是一个函数，因为我很慢，它将确定线段和圆是否发生碰撞，在 javascript 中(使用画布)
I'm looking for a definitive answer, maybe a function cos I'm slow, that will determine if a line segment and circle have collided, in javascript (working with canvas)
像下面这样的函数，如果发生碰撞，则返回 true，否则返回 false.我什至可以给你捐一个婴儿.
A function like the one below that simply returns true if collided or false if not would be awesome. I might even donate a baby to you.
function isCollided(lineP1x, lineP1y, lineP2x, lineP2y, circlex, circley, radius) {
...
}
我找到了很多公式，像这个，但它们超出了我的范围头.
I've found plenty of formulas, like this one, but they are over my head.
推荐答案
这里你需要一些数学:
如果您一般不知道如何求解方程，这是基本概念.我会把剩下的想法留给你.;) 弄清楚 CD 的长度并不难.
This is the basic concept if you don't know how to solve equations in general. I will leave the rest of the thinking to you. ;) Figuring out CD's length isn't that hard.
如果您要问如何，那就是如何:在 JavaScript 中查找冲突有点复杂.
If you are asking how, that's how: Finding collisions in JavaScript is kind of complicated.
