Creating an Orthographic Decal#
The following code illustrates how to create an orthographic decal, set its parameters and add the node to UnigineEditor.
Source code (C++)
// AppWorldLogic.h
#include <UnigineLogic.h>
#include <UnigineEditor.h>
#include <UnigineDecals.h>
class AppWorldLogic : public Unigine::WorldLogic {
public:
AppWorldLogic();
virtual ~AppWorldLogic();
virtual int init();
virtual int update();
virtual int postUpdate();
virtual int updatePhysics();
virtual int shutdown();
virtual int save(const Unigine::StreamPtr &stream);
virtual int restore(const Unigine::StreamPtr &stream);
private:
Unigine::DecalOrthoPtr decal_ortho;
};Source code (C++)
// AppWorldLogic.cpp
#include "AppWorldLogic.h";
using namespace Unigine;
int AppWorldLogic::init()
{
// create an ortho decal and setting its radius to 10, width and height to 2
decal_ortho = DecalOrtho::create();
decal_ortho->setRadius(10.0f);
decal_ortho->setWidth(2.0f);
decal_ortho->setHeight(2.0f);
// set the name and position of the decal
decal_ortho->setName("Ortho Decal");
decal_ortho->setWorldPosition(Math::Vec3(0.0f, 0.0f, 5.0f));
return 1;
