Cocos2d-x Study Notes (12) 3D Effects

The special effect class is the gridaction class, which is actually a grid-based 3D effect class. You need to enable OpenGL depth buffering, otherwise 3D distortion is easy.

Below is an snippet, which creates a Grid Object and adds it to the current layer. At the same time, it adds the object for 3D effects to the grid object.

        gridNodeTarget = NodeGrid::create();    addChild(gridNodeTarget);// add to current layer    auto bg = Sprite::create("background.png");    bg->setPosition(Vec2(visibleSize.width/2, visibleSize.height /2));    gridNodeTarget->addChild(bg);    sprite = Sprite::create("hero.png");    sprite->setPosition(Vec2(visibleSize.width / 2, visibleSize.height / 2));    gridNodeTarget->addChild(sprite);

Below is the use of the 3D special effects class, and the effect will not be displayed here.

Void myaction: gomenu (ref * psender) {size visiblesize = Director: getinstance ()-> getvisiblesize (); log ("tag = % I ", this-> gettag (); Switch (this-> gettag () {Case kflipx3d: // X axis 3D flip, the parameter is duration gridnodetarget-> runaction (flipx3d :: create (3.0f); break; Case kpageturn3d: // page flip effect. The first parameter is duration, and the second parameter is grid size gridnodetarget-> runaction (pageturn3d :: create (3.0f, size (15, 10); break; Case klens3d: // convex lens effect. The first parameter is duration, and the second parameter is grid size, the third parameter is the lens center, and the fourth parameter is the lens radius gridnodetarget-> runaction (lens3d: Create (3.0f, size (), vec2 (visiblesize. width/2, visiblesize. height/2), 240); break; Case kshaky3d: // special shaking effect. The first parameter is the duration parameter.

In fact, 3D effects are nothing more than making 2D effects more realistic and closer to the real world.
