错误 C2228:“.x"的左边必须有类/结构/联合 [英] error C2228: left of '.x' must have class/struct/union

问题描述

我收到错误，完全不知道为什么！

I am getting the error and have absolutely no idea why!

//create a circle shape.
sf::CircleShape shape;
shape.setRadius(25);
shape.setFillColor(sf::Color(100,250,250));

//circle collision geometry
circle circleTest(shape.getPosition.x,shape.getPosition.y,shape.getRadius())

Circle 是圆形碰撞几何体的类.它在构造函数上失败

Circle is the class for circle collision geometry.And it fails on the constructor

(shape.getPosition.x,shape.getPosition.y,shape.getRadius())

(shape.getPosition.x,shape.getPosition.y,shape.getRadius())

我不知道为什么我收到错误，它工作正常然后突然给了我标题中的错误.

I don't know why i got the error , it worked fine then all of a sudden gave me the error in the title.

推荐答案

getPosition 是一个 函数.您必须调用它并访问其返回值的成员.

getPosition is a function. You must call it and access its return value’s members.
