setTexture with RenderTexture makes the cc.Sprite invisible

cocos2d-x JavaScript
#1

I’m using cocos2d-js 3.16 (jsbinding)

First a working example of two sprites :

var sprite1 = cc.Sprite.create(res.objectA_png);
sprite1.setPosition(cc.winSize.width * 0.5, cc.winSize.height * 0.5);
this.addChild(sprite1);

var sprite2 = cc.Sprite.create(res.objectB_png);
sprite2.setPosition(cc.winSize.width * 0.5, cc.winSize.height * 0.5 - 200);
this.addChild(sprite2);

And the result is :

And then replace the texture of Sprite1 with the texture of Sprite2, add the two line of codes:

sprite1.setTexture(sprite2.getTexture());
sprite1.setTextureRect(sprite2.getTextureRect());

And it works fine as well :

And then I created a function to generate a sprite using cc.RenderTexture to capture a given node:

generateSprite = function(target) {
    var renderTexture = new cc.RenderTexture(target.width, target.height);
    renderTexture.setAutoDraw(false);
    renderTexture.setKeepMatrix(true);
    renderTexture.beginWithClear(255, 0, 0, 100);  // <== ==== color for debug
    renderTexture.setVirtualViewport(
        cc.p(target.x - target.width / 2, target.y - target.height / 2),
        cc.rect(0, 0, cc.winSize.width, cc.winSize.height),
        cc.rect(0, 0, cc.director.getWinSizeInPixels().width, cc.director.getWinSizeInPixels().height));
    target.visit();
    renderTexture.end();
    //
    var cloneSprite = new cc.Sprite(renderTexture.getSprite().getTexture());
    cloneSprite.setFlippedY(true);
    return cloneSprite;
};

And then I use this function to generate Sprite2 :

var sprite1 = cc.Sprite.create(res.objectA_png);
sprite1.setPosition(cc.winSize.width * 0.5, cc.winSize.height * 0.5);
this.addChild(sprite1);

var sprite2 = this.generateSprite(sprite1);
sprite2.setPosition(cc.winSize.width * 0.5, cc.winSize.height * 0.5 - 200);
this.addChild(sprite2);

And it still works fine :

And the last part, I tried to replace the texture of Sprite1 using the texture of sprite2 just as I did above:

sprite1.setTexture(sprite2.getTexture());
sprite1.setTextureRect(sprite2.getTextureRect());

But this time, after doing this , I get:

18%20PM
18%20PM1138×638 2.55 KB

No warning or errors shown in the console… I am really not sure what is going wrong here …

Any suggestion will be appreciated, thanks :slight_smile:
