CEGUI Integration - Working kinda...

[EvilNoodle]

Hi,

 

I followed the information in this forum and the CEGUI site to get CEGUI working in Leadwerks. The GUI renders OK and the window is fine except for the title text that is totally illegible.

 

The code is below and I suspect the issue is due to where I have the renderGUI() command in the render loop.

 

Any suggestions would be greatly appreciated.

 

Cheers

put

 

glPixelStoref(0x806E, 0);  
glPixelStoref(GL_PACK_ROW_LENGTH, 0);  
glPixelStoref(GL_UNPACK_ROW_LENGTH, 0); 

 

 

Right before

 

CEGUI::System::getSingleton().renderGUI();

 

=)

And not that it matters a great deal, but you should inject input before rendering the GUI or you will always be 1 frame behind
