成员函数说明

◆ create()

static MySprite * MySprite::create ( const std::string & spritefilename )

inlinestatic

在文件 NodeTest.cpp 第 967 行定义.

    {
        auto sprite = new (std::nothrow) MySprite;
        sprite->initWithFile(spritefilename);
        sprite->autorelease();
        auto program = backend::Program::getBuiltinProgram(backend::ProgramType::POSITION_TEXTURE_COLOR);
        auto programState = new (std::nothrow) backend::ProgramState(program);
        programState->autorelease();
        sprite->setProgramState(programState);
        return sprite;
    }

被这些函数引用 CameraTest1::CameraTest1() , 以及 CameraTest2::CameraTest2().

这是这个函数的调用关系图:

◆ draw()

void MySprite::draw	(	Renderer *	renderer,
		const Mat4 &	transform,
		uint32_t	flags
	)

overridevirtual

在文件 NodeTest.cpp 第 998 行定义.

{
    const auto& projectionMat = Director::getInstance()->getMatrix(MATRIX_STACK_TYPE::MATRIX_STACK_PROJECTION);
    auto mvpMatrix = projectionMat * transform;
    _customCommand.getPipelineDescriptor().programState->setUniform(_mvpMatrixLocation, mvpMatrix.m, sizeof(mvpMatrix.m));
    _customCommand.init(_globalZOrder, transform, flags);
    renderer->addCommand(&_customCommand);
}

引用了 _customCommand.

◆ setProgramState()

void MySprite::setProgramState ( backend::ProgramState * programState )

overridevirtual

在文件 NodeTest.cpp 第 986 行定义.

{
    Sprite::setProgramState(programState);
    auto& pipelineDescriptor = _customCommand.getPipelineDescriptor();
    pipelineDescriptor.programState = programState;
 
    _customCommand.setDrawType(CustomCommand::DrawType::ARRAY);
    _customCommand.setPrimitiveType(CustomCommand::PrimitiveType::TRIANGLE_STRIP);
    _customCommand.createVertexBuffer(sizeof(V3F_C4B_T2F), 4, CustomCommand::BufferUsage::STATIC);
    _customCommand.updateVertexBuffer(&_quad, 4*sizeof(V3F_C4B_T2F));
}

引用了 _customCommand.

类成员变量说明

◆ _customCommand

CustomCommand MySprite::_customCommand

protected

在文件 NodeTest.cpp 第 982 行定义.

被这些函数引用 draw() , 以及 setProgramState().
