我正在嘗試用云、山、樹、峽谷等對(duì)象創(chuàng)建背景風(fēng)景。一切都很順利，除了當(dāng)我創(chuàng)建云對(duì)象時(shí)。我已為云對(duì)象聲明了，并將設(shè)置函數(shù)中var cloud的坐標(biāo)值初始化為。然而，當(dāng)我嘗試在下面提到的函數(shù)中創(chuàng)建具有橢圓形狀的云對(duì)象時(shí)，它給我?guī)砹藘蓚€(gè)問題：cloudcloud = (pos_x: 200, pos_y: 70, diameter: 130);draw()cloud.pos_x當(dāng)我輸入時(shí)，cloud.我沒有得到自動(dòng)填充ellipse();運(yùn)行代碼后出現(xiàn)錯(cuò)誤*sketch.js:23 Uncaught Syntax Error: Unexpected token ':'*（點(diǎn)彼此重疊）。我希望我已經(jīng)為您提供了足夠的細(xì)節(jié)來理解這個(gè)問題。謝謝。var floorPos_y;var gameChar_x;var gameChar_y;var treePos_x;var treePos_y;var canyon;var collectable;var mountain;var cloud; var cloudPos_x: var cloudPos_y; var cloudDiameter; function setup(){    createCanvas(1024, 576);    floorPos_y = 432; //NB. we are now using a variable for the floor position    //NB.
