A WigetSprite doesn't rotate as I think.

Hello,

 

I want to rotate a WidgetSprite component.

 

I wrote below code. It works well.

 

{
m_testWindow = new WidgetWindow( m_GUI , "test" );
m_testWindow.setSizeable( 1 );
m_testWindow.setWidth( m_width + 30);
m_testWindow.setHeight( m_height + 50);
m_testWindow.setPosition(m_posX, m_posY);
}

{
m_testSprite = new WidgetSprite(m_GUI);
m_testSprite.addLayer();

m_testSprite.setTexture("test.jpg");
m_testSprite.setLayerTransform(0, rotateZ(30.0f));

m_testSprite.setLayerTexCoord(0, vec4(0.0f, 0.0f, 1.0f, 1.0f));
}

m_testWindow.addChild(m_testSprite);
m_GUI.addChild( m_testWindow, GUI_ALIGN_OVERLAP );

 

 

But when I add some code. The WigetSprite doesn't rotate as I think.

{
m_testWindow = new WidgetWindow( m_GUI , "test" );
m_testWindow.setSizeable( 1 );
m_testWindow.setWidth( m_width + 30);
m_testWindow.setHeight( m_height + 50);
m_testWindow.setPosition(m_posX, m_posY);
}

{
m_testSprite = new WidgetSprite(m_GUI);
m_testSprite.addLayer();

m_testSprite.setTexture("test.jpg");
m_testSprite.setLayerTransform(0, rotateZ(30.0f));

m_testSprite.setLayerTexCoord(0, vec4(0.0f, 0.0f, 1.0f, 1.0f));

m_testSprite.setWidth( m_width );
m_testSprite.setHeight( m_height );
}

m_testWindow.addChild(m_testSprite);
m_GUI.addChild( m_testWindow, GUI_ALIGN_OVERLAP );

 

What's the problem?

Maybe

 

m_testSprite.setWidth( m_width );
m_testSprite.setHeight( m_height );

 

should be set before transform. Have a look into working sprite sample <UNIGINE-SDK>/data/saples/widgets/sripte_00.cpp and use it as template.

thank you.

 

 

But that is not the problem.

Not changed.

In both cases it is rotated by 30 degrees. But when you call setWidth() and setHeight() for the 2nd time, you simply resize the widget together with its rotated layer, i.e. make it smaller by X and Y.

What did you want your code to do?
