cocos2dx V3.2 customer draw method

in V3.0

Works fine in 3.0:

void JellyLogic::draw(Renderer *renderer, const kmMat4 &transform, bool transformUpdated) {
    kmGLPushMatrix();
    GL::bindTexture2D(texture->getName());
    texture->getShaderProgram()->use();
    texture->getShaderProgram()->setUniformsForBuiltins();
    GL::enableVertexAttribs(GL::VERTEX_ATTRIB_FLAG_POSITION | GL::VERTEX_ATTRIB_FLAG_TEX_COORDS);
    glVertexAttribPointer(GLProgram::VERTEX_ATTRIB_POSITION, 2, GL_FLOAT, GL_FALSE, 0, triangleStripPos);
    glVertexAttribPointer(GLProgram::VERTEX_ATTRIB_TEX_COORDS, 2, GL_FLOAT, GL_FALSE, 0, textCoords);
    glDrawArrays(GL_TRIANGLE_STRIP, 0,  NUM_VERTEX);
    kmGLPopMatrix();
}

I guess I need to change the texture->getShaderProgram()->use() to texture->getGlProgram()->use() in 3.2
The code compiles fine but no images is showing.

in V3.2

uses a command queue to render nodes and thus custom drawing routines should be wrapped with the command.

o we need to use customCommand to do this.

CustomCommand _customCommand; // in header or wherever makes sense for you

 _customCommand.init(_globalZOrder);

_customCommand.func = CC_CALLBACK_0(JellyLogic::onDraw, this, transform, flags);

renderer->addCommand(&_customCommand);

create JellyLogic::onDraw(...) and put that code above in it.

void JellyLogic::draw(Renderer *renderer, const Mat4 &transform, uint32_t flags)
{
    _customCommand.init(_globalZOrder);
    _customCommand.func = CC_CALLBACK_0(JellyLogic::onDraw, this, transform, flags);
    renderer->addCommand(&_customCommand);
}

void JellyLogic::onDraw(const Mat4 &transform, uint32_t flags) {
    kmGLPushMatrix();
    GL::bindTexture2D(texture->getName());
    texture->getGLProgram()->use();
    texture->getGLProgram()->setUniformsForBuiltins();
    GL::enableVertexAttribs(GL::VERTEX_ATTRIB_FLAG_POSITION | GL::VERTEX_ATTRIB_FLAG_TEX_COORD);
    glVertexAttribPointer(GLProgram::VERTEX_ATTRIB_POSITION, 2, GL_FLOAT, GL_FALSE, 0, triangleStripPos);
    glVertexAttribPointer(GLProgram::VERTEX_ATTRIB_TEX_COORDS, 2, GL_FLOAT, GL_FALSE, 0, textCoords);
    glDrawArrays(GL_TRIANGLE_STRIP, 0,  NUM_VERTEX);
    kmGLPopMatrix();
}

综合以上例子跟下面的图表，可以非常清楚看到这个新的Render 机制。   rendering Node during vist will not call into OpengGL anymore
