The splash screen 00064 should be displayed for 2 seconds. 00065 00066 Thank you. 00067 */ 00068 00069 00070 #ifndef KYRA_TILERESOURCE_INCLUDED 00071 #define KYRA_TILERESOURCE_INCLUDED 00072 00073 #include "kyraresource.h" 00074 #include "../engine/krmath.h" 00075 #include "pixelblock.h" 00076 00080 class KrTileResource : public KrResource 00081 { 00082 public: 00083 // Create by reading from a .dat file 00084 KrTileResource( U32 size, SDL_RWops* data ); 00085 00086 KrTileResource( const std::string& name, 00087 KrPaintInfo* surface, 00088 int x, int y, int size ); 00089 00090 virtual ~KrTileResource(); 00091 00092 virtual U32 Type() { return KYRATAG_TILE; } 00093 virtual const std::string& TypeName() { return tileName; } 00094 virtual KrTileResource* ToTileResource(){ return this; } 00095 00097 int Size() const { return pixelBlock[0]->Width(); } 00099 bool Alpha() { return pixelBlock[0]->Alpha(); } 00100 00101 // -- internal -- // 00102 void Draw( KrPaintInfo* paintInfo, 00103 const KrMatrix2& matrix, 00104 int rotation, 00105 const KrColorTransform& cForm, 00106 const KrRect& clipping, 00107 int quality, 00108 int openGLZ ); 00109 00110 /* Do a HitTest (see KrImageTree::HitTest) in transformed 00111 coordinates.
