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#)
using Unigine;

namespace UnigineApp
{
	class AppWorldLogic : WorldLogic
	{
        private DecalProj decal_proj;

        public override bool Init()
        {

			// create an proj decal and setting its radius to 10, fov to 60, aspect to 1.0f, material to "decal_base"
            decal_proj = new DecalProj(10.0f, 60.0f, 1.0f, "decal_base");

			// set the name and position of the decal
            decal_proj.setName("Proj Decal");
            decal_proj.setWorldPosition(new Vec3(0.0f, 0.0f, 5.0f));

            return true;
        }
    	
		public override bool Shutdown()
		{
			// clear pointer
			decal_proj.clearPtr();

			return true;
		}
	}
}
