自定义shader会影响其他精灵的绘制
@truekbcl 写道：
各位好。
我自定义了一个shader，绘制Node后，会影响其他Sprite的绘制。请问怎么解决？
以下是详细说明。shader定义：
vsh
attribute vec4 a_position;
attribute vec2 a_texCoord;
varying vec2 v_texCoord;
void main(void) {
gl_Position = a_position;
v_texCoord = a_texCoord;
}fsh
varying vec2 v_texCoord;
uniform sampler2D tex_y;
uniform sampler2D tex_u;
uniform sampler2D tex_v;
void main(void) {
vec3 yuv;
vec3 rgb;
yuv.x = texture2D(tex_y, v_texCoord).r;
yuv.y = texture2D(tex_u, v_texCoord).r - 0.5;
yuv.z = texture2D(tex_v, v_texCoord).r - 0.5;
rgb = mat3(1, 1, 1,
0, -0.39465, 2.03211,
1.13983, -0.58060, 0) * yuv;
gl_FragColor = vec4(rgb, 1);
};代码如下：
bool xxx::init()
{
...
_node = Node::create();
create_program(_node);
...
}void xxx::create_program(cocos2d::Node * node)
{
_program = GLProgram::createWithByteArrays(vsh, fsh);
state = GLProgramState::getOrCreateWithGLProgram(program);
node->setGLProgramState(_state);_state->setVertexAttribPointer("a_position", 2, GL_FLOAT, 0, 0, _vertex_vertices); glEnableVertexAttribArray(_program->getAttribLocation("a_position")); _state->setVertexAttribPointer("a_texCoord", 2, GL_FLOAT, 0, 0, _texture_vertices); glEnableVertexAttribArray(_program->getAttribLocation("a_texCoord")); _state->applyAttributes(); glGenTextures(1, &_id_y); glBindTexture(GL_TEXTURE_2D, _id_y); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glGenTextures(1, &_id_u); glBindTexture(GL_TEXTURE_2D, _id_u); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glGenTextures(1, &_id_v); glBindTexture(GL_TEXTURE_2D, _id_v); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);}
void xxx::display()
{
GL::enableVertexAttribs(GL::VERTEX_ATTRIB_FLAG_POSITION | GL::VERTEX_ATTRIB_FLAG_TEX_COORD);_program->use(); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, _id_y); glTexImage2D(GL_TEXTURE_2D, 0, GL_RED, _pixel_w, _pixel_h, 0, GL_RED, GL_UNSIGNED_BYTE, _plane[0]); glUniform1i(_program->getUniformLocation("tex_y"), 0); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, _id_u); glTexImage2D(GL_TEXTURE_2D, 0, GL_RED, _pixel_w / 2, _pixel_h / 2, 0, GL_RED, GL_UNSIGNED_BYTE, _plane[1]); glUniform1i(_program->getUniformLocation("tex_u"), 1); glActiveTexture(GL_TEXTURE2); glBindTexture(GL_TEXTURE_2D, _id_v); glTexImage2D(GL_TEXTURE_2D, 0, GL_RED, _pixel_w / 2, _pixel_h / 2, 0, GL_RED, GL_UNSIGNED_BYTE, _plane[2]); glUniform1i(_program->getUniformLocation("tex_v"), 2); glDrawArrays(GL_TRIANGLE_STRIP, 0, 4);}
代码解说：
1、本类是继承于Layer，内部保存一个Node，用来绘制背景。下划线的变量是对象的变量
2、create_program()创建shader，并且创建三个缓冲区。
3、重载visit，并绑定display函数。
4、在display中绘制。当调用display后，可以正常显示yuv数据，但是其他层的Sprite也是用这个shader绘制的。
如图
