thanks, sounds great!
Specifically there are two lines that need to be changed. The first is the one you identified already:
Before:
[sprite setScale:img->scale / [sprite contentSizeInPixels].height * contentScaleFactor ];
After:
[sprite setScale:img->scale / [sprite contentSize].height ];
Actually, if you don't want to use debug draw, that's all you should need to change. If you do want to use debug draw (and I highly recommend having it available to see what's happening), you will also need to change the other place where contentScaleFactor is used, in BasicRUBELayer.mm:
Before:
m_debugDraw = new GLESDebugDraw( [[CCDirector sharedDirector] contentScaleFactor] );
After:
m_debugDraw = new GLESDebugDraw( 1 );
Of course, to actually get the debug draw rendering with the newer shader model method, you'll also need to copy the way it is done in the HelloWorldLayer from the template, but I guess you have figured that out already. In any case, I ended up with something like this:
Code: Select all
-(void) draw
{
if ( !m_world )
return;
ccGLEnableVertexAttribs( kCCVertexAttribFlag_Position );
kmGLPushMatrix();
m_world->DrawDebugData();
if ( m_mouseJoint ) {
b2Vec2 p1 = m_mouseJoint->GetAnchorB();
b2Vec2 p2 = m_mouseJoint->GetTarget();
b2Color c;
c.Set(0.0f, 1.0f, 0.0f);
m_debugDraw->DrawPoint(p1, 4.0f, c);
m_debugDraw->DrawPoint(p2, 4.0f, c);
c.Set(0.8f, 0.8f, 0.8f);
m_debugDraw->DrawSegment(p1, p2, c);
}
kmGLPopMatrix();
}
