我正在尝试让我的 gif “跳跃”,同时也以 730 的 y 值返回休息。不多也不少。当 wifi 不可用时,它的运行程度与恐龙游戏相同。我也想包括一个重力功能。我不知道该怎么做。(我对编码很陌生。)有什么提示吗?
[代码如下]
let img; //background
var bgImg; //also the background
var x1 = 0;
var x2;
var scrollSpeed = 4; //how fast background is
let bing; //for music
let cat = { //coordinates for catbus
x:70,
y:730
}
var mode; //determines whether the game has started
function preload() {
bgImg = loadImage("backgwound.png"); //importing background
bing=loadSound('catbus theme song.mp3'); //importing music
}
function setup() {
createCanvas(1000, 1000); //canvas size
img = loadImage("backgwound.png"); //background in
x2 = width;
bing.loop() //loops the music
catGif=createImg("catgif.gif") //creates catbus
catGif. position(cat.x, cat.y) //creates position
catGif. size(270,100) //creates how big
mode = 0; //game start
textSize(50); //text size
}
function draw() {
let time = frameCount; //start background loop
image(img, 0 - time, 0);
image(bgImg, x1, 2, width, height);
image(bgImg, x2, 2, width, height);
x1 -= scrollSpeed;
x2 -= scrollSpeed;
if (x1 <= -width) {
x1 = width;
}
if (x2 <= -width) {
x2 = width;
} //end background loop
fill("white") //text colour
if(mode==0){
text('Press SPACE to start the game.',150,500); //what text to type
}
if(mode==0){
text('CATBUS BIZZARE ADVENTURE',135,450) //what text to type
}
}
function pickRandom() {
x = random(20, width - 20);
}
