Creating a Projected Decal#
The following code illustrates how to create a projected 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::DecalProjPtr decal_proj;
};Source code (C++)
// AppWorldLogic.cpp
#include "AppWorldLogic.h";
using namespace Unigine;
int AppWorldLogic::init()
{
// create an proj decal and setting its radius to 10, fov to 60, aspect to 1.0f, material to "decal_base"
decal_proj = DecalProj::create();
decal_proj->setRadius(10.0f);
decal_proj->setFov(60.0f);
decal_proj->setAspect(1.0f);
// set the name and position of the decal
decal_proj->setName("Proj Decal");
decal_proj->setWorldPosition(Math::Vec3(0.0f, 0.0f, 5.0f));
return 1;

Members
static DecalProjPtr create ( ) #
Constructor. Creates a new projected decal with default parameters.void setAspect ( float aspect ) #
Sets the new aspect ratio of the decal, in units.Arguments
- float aspect - The aspect ratio of the decal, in units. If a negative value is provided, 0 will be used instead.
float getAspect ( ) const#
Returns the current aspect ratio of the decal.Return value
The aspect ratio of the decal, in units.void setFov ( float fov ) #
Sets a new field of view of the decal's projector.Arguments
- float fov - A field of view of the decal's projector, in degrees. The provided value will be clamped in the range [1;90].
float getFov ( ) const#
Returns the current field of view of the decal's projector.Return value
The field of view of the decal's projector, in degrees.Math::mat4 getProjection ( ) const#
Returns the projection matrix.Return value
The projection matrix of the decal.void setZNear ( float znear ) #
Sets a distance to the near clipping plane of the decal.Arguments
- float znear - A new distance to the near clipping plane, in units. If a negative value is provided, 0 will be used instead.
float getZNear ( ) const#
Returns the distance to the near clipping plane of the decal.Return value
The distance to the near clipping plane, in units.static int type ( ) #
Returns the type of the node.Return value
