我的代码有效(不会失败),但它没有做正确的事情。
每次我想生成一个新的“块”时,我都会调用“生成”函数,每次调用时都会将一个新数字传递给函数。它可以很好地生成块,但它不会生成我希望它生成的内容。
如果上一代是空格,我希望它生成空格、跳跃、幻灯片或间隙。但如果上一代不是空间,则生成空间。它不这样做。它有时会产生 2 个间隙、2 个跳跃或 2 个幻灯片,我不知道为什么......?
这是我的代码:
var ptg = 'space'; // what was previously generated to top
var wtgt; // what is currently being generated to top
var chunktogenerateto = 0;
function generate(a){
chunktogenerateto = a;
var rand1 = Math.floor(Math.random()*100) + 1;
if(ptg == 'space' && rand1 <= 25){
wtgt = 'space';
}
else if(ptg == 'space' && rand1 <= 50 && rand1 > 25){
wtgt = 'jump';
}
else if(ptg == 'space' && rand1 <= 75 && rand1 > 50){
wtgt = 'slide';
}
else if(ptg == 'space' && rand1 > 75){
wtgt = 'gap';
}
else{
wtgt = 'space';
}
ptg = wtgt;
topGen(wtgt);
}
function topGen(g){
document.getElementById('t' + chunktogenerateto).setAttribute('src','images/terrain/t' + g + '.png');
}
我希望这不是一个错字...帮助!
“生成”的调用来自:
var chunkpos = new Array();
chunkpos[0] = -100;
chunkpos[1] = 0;
chunkpos[2] = 100;
chunkpos[3] = 200;
chunkpos[4] = 300;
chunkpos[5] = 400;
chunkpos[6] = 500;
chunkpos[7] = 600;
chunkpos[8] = 700;
chunkpos[9] = 800;
chunkpos[10] = 900;
chunkpos[11] = 1000;
var temppos = new Array();
var time1;
var millis1;
var time2;
var millis2;
var millis3;
var firstreset = true;
var pos;
var poschange;
function moveLevel(){
if(firstreset == true){
resetTime();
}
var time2 = new Date();
var millis2 = time2.getTime();
var millis3 = millis2 - millis1;
poschange = Math.floor(millis3 / 5);
for(i = 0; i < chunkpos.length; i++){
temppos[i] = chunkpos[i] - poschange;
if(temppos[i] <= -150){
generate(i);
temppos[i] += 1200;
}
pos = temppos[i];
document.getElementById('chunk' + i).setAttribute('style','left: ' + pos + 'px;');
}
}
function resetTime(){
time1 = new Date();
millis1 = time1.getTime();
if(firstreset != true){
for(i = 0; i < chunkpos.length; i++){
chunkpos[i] = temppos[i];
}
}
firstreset = false;
setTimeout('resetTime()',1000);
}
对“moveLevel”的调用来自:
window.onload = function(){
if(test = 'runnable')
{
gameLoop();
}
else
{
document.getElementById('gm').innerHTML = (gm + 'Failed to run game.');
}
}
function gameLoop(){
if(currentscreen == 'playing'){
moveLevel();
}
setTimeout('gameLoop()',0);
}
