[SOLVED] engine.visualizer.renderLine2D in a viewport widget

[Simon.Anderson]

Hi, 

 

I'm trying to draw a line in a WidgetSpriteViewport.  

 

The line is appearing in the main viewport underneath but not when the widget is active (sitting on top of the main viewport area).  Can this be done?

 

Here's the code:

 

m_viewportSprite.setModelview( player.getIWorldTransform() );
m_viewportSprite.setProjection( player.getProjection() );

 

....

...

...

 

vec3 start = vec3( 0,0, 0 );
vec3 end = vec3( 1,1, 0 );

 

engine.visualizer.setProjection( player.getProjection() );
engine.visualizer.setModelview( player.getIWorldTransform() );

engine.visualizer.renderLine2D( start, end, colors::Grey( 0.6f, 0.6f ) );

 

Any help would be appreciated.

 

Thanks,

Simon

ok,

 

realised I should be using a canvas  on top of the viewport - for some reason I still can't see anything though.:

 

// Draw the shadow cursor
                m_Canvas.setPosition( posx, posy );
                m_Canvas.setWidth( viewportWidth );
                m_Canvas.setHeight( viewportHeight );
               
                m_Canvas.clear();
                // Yellow line around region
                int id = m_Canvas.addLine();
                m_Canvas.setLineColor( id, colors::Grey( 0.6f, 0.6f ) );
                m_Canvas.addLinePoint( id, vec3( 0, 0, 0 ) );
                m_Canvas.addLinePoint( id, vec3( 500, 500, 0 ) );

 

 

Any Ideas?

ok sorted it - simple mistake at my end.
