好的,这就是我的错误:'Enemy'未在此范围内声明.错误在map.h文件中,即使map.h包含enemy.h,如图所示
#ifndef MAP_H_INCLUDED
#define MAP_H_INCLUDED

这是敌人

那么,有人可以帮忙吗？

但是当我将它转换为统一的着色器语言时，除了透明度（并且没有模糊以太）之外，我的纹理中除了白色什么也没有。
这是我的 Unity 模糊着色器代码：
Shader "Unlit/UnlitShaderTest"
{
Properties
{
_MainTex ("Texture", 2D) = "white" {}
}
SubShader
{
Tags { "RenderType"="Opaque" }
LOD 100

float4 vertex : POSITION;
float2 uv : TEXCOORD0;
};
struct v2f
{
float2 uv : TEXCOORD0;
float4 vertex : SV_POSITION;
};
sampler2D _MainTex;
float4 _MainTex_ST;
uniform float resolution = 800;
uniform float radius = 400;
uniform float2 dir = float2(0,1); …我正在尝试创建一个结构数组,但稍后定义它的大小,如下所示:
struct xy{
int x;
int y;
};
int main(){
xy pos;
int size = 10;
pos = new xy[size];
pos[0].x = 5;
}
但无论我尝试什么,我都无法让它发挥作用.此外,我不想使用矢量,所以请不要说我应该.
对不起,如果这没有任何意义,但我正在尽我所能了解它.
所以我基本上有一个指向openGL中纹理数据的指针,它是16 bpp(pcx.image.data16),我需要打开每个像素的alpha位.所以我想出了这个,但你可以说它真的很糟糕.
for(int i = 0; i < (TEXTURE_SIZE_128 * TEXTURE_SIZE_128); i++){
pcx.image.data16 |= 1 << ((16 * i) + 15);
}
我收到这些错误:
c:/Users/me/Desktop/neronds/source/neroedge.cpp:40:43: error: invalid operands of types 'u16* {aka short unsigned int*}' and 'int' to binary 'operator|'
c:/Users/me/Desktop/neronds/source/neroedge.cpp:40:43: error: in evaluation of 'operator|=(u16* {aka short unsigned int*}, int)'
如何修复这些错误,我是否正在改变每像素的alpha位？
我该如何解析php中的url？我想做到这一点
[url=http://www.google.com]Google[/url]
变成:
<a href="http://www.google.com">Google</a>
这是我用于其他bb代码的代码:
function postparser($post){
$post = str_replace("\n",'END_OF_LINE',$post);
$post = str_replace("[line]",'HORIZONTAL_LINE',$post);
$post = str_replace("[bold]",'BOLD_TEXT_START',$post);
$post = str_replace("[/bold]",'BOLD_TEXT_END',$post);
$post = str_replace("[yt]",'YOUTUBE_START',$post);
$post = str_replace("[/yt]",'YOUTUBE_END',$post);
$post = sanitize($post);
$post = str_replace("END_OF_LINE",'<br />',$post);
$post = str_replace("HORIZONTAL_LINE",'<hr />',$post);
$post = str_replace("BOLD_TEXT_START",'<b>',$post);
$post = str_replace("BOLD_TEXT_END",'</b>',$post);
$post = str_replace("YOUTUBE_START",'<iframe width="560" height="315" src="http://www.youtube.com/embed/',$post);
$post = str_replace("YOUTUBE_END",'" frameborder="0" allowfullscreen></iframe>',$post);
return $post;
}
我该怎么做呢？
这是非常糟糕的我必须做一个硬重启(按下电源按钮),它甚至没有给我时间调试,所以我基本上搞砸了,如果我没有在这里得到答案.我知道它是服务器端(因为它发生在我不运行客户端时,但如果我这样做也会发生).
这是服务器代码:

var blockArray = new Array(1);
blockArray[0] = new Array(1);
function readLevel() {
for (var i = 0; i < level.length; i++) {
for (var j = 0; j < level[i].length; j++) {
var tempImg = new Image();
tempImg.src = "images/block.png";
blockArray[i][j] = new block(i * blockSize, j * blockSize, …只是想知道我的代码有什么问题.这是wordpress,但我正在制作一个自定义主题. http://prime.programming-designs.com/blog/
好吧,所以在任何人问之前,是的我确实<gl/gl.h>包括在内.任何人都知道为什么这个功能glGetTexLevelParameter没有出现？
