I cant seam to get to blit any surface from the many my constructor makes, its job is to take 15 images from a sprite sheet, cut them up, rotate each 360 times, save each to a surface array so i can use them later
but whenever I try I cant seam to use my surfaces
this does nothing;
blit.ApplySurface( 0, 0, armsSurfaceArray[1][1], background, NULL,0,1 );
SDL_Flip( background);
constructor
SDL_Surface *torsoSurfaceArray[7][361];
SDL_Surface *armsSurfaceArray[7][361];
SDL_Surface *legsSurfaceArray[7][361];
//intitalizes SDL, and sets all surfaces
Surface::Surface()
{
const int SCREEN_WIDTH = 500;
const int SCREEN_HEIGHT = 400;
const int SCREEN_BPP = 32;
TTF_Init();
SDL_Init( SDL_INIT_EVERYTHING );
background = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP, SDL_SWSURFACE );
SDL_WM_SetCaption( "running", NULL );
//sets all surfaces to NULL
for (int i= 1; i < 7; i++)
{
for (int j= 0; j < 360; j++)
{
torsoSurfaceArray[j] = background;
armsSurfaceArray[j] = background;
legsSurfaceArray[j] = background;
}
}
int spriteCutWidth = 187;
int spriteCutHight = 100;
int spriteXcords[6];
spriteXcords[1] = 119;
spriteXcords[2] = 312;
spriteXcords[3] = 507;
spriteXcords[4] = 701;
spriteXcords[5] = 895;
int spriteYcords[4];
spriteYcords[1] = 351;
spriteYcords[2] = 479;
spriteYcords[3] = 608;
SDL_Rect spriteCut[6];
SDL_WM_SetCaption( "Loading...", NULL );
SDL_Surface *playerSpriteSheetImg = IMG_Load( "debug/Generic_Images/player_sprite_sheet.tga" );
//going through once for every stride
for (int i= 1; i < 6; i++)
{
//360 times, one for each angle
for (int j= 0; j < 5; j++)
{
spriteCut.h = spriteCutHight;
spriteCut.w = spriteCutWidth;
spriteCut.x = spriteXcords;
spriteCut.y = spriteYcords[2];
blit.ApplySurface( 0, 0, playerSpriteSheetImg, torsoSurfaceArray[j], &spriteCut,j,1 );
//blit.ApplySurface( 0, 0, background, torsoSurfaceArray[j], NULL,0,1 );
//SDL_FreeSurface( background );
spriteCut.y = spriteYcords[3];
blit.ApplySurface( 0, 0, playerSpriteSheetImg, legsSurfaceArray[j], &spriteCut,j,1 );
//blit.ApplySurface( 0, 0, background, legsSurfaceArray[j], NULL,0,1 );
//SDL_FreeSurface( background );
spriteCut.y = spriteYcords[1];
blit.ApplySurface( 0, 0, playerSpriteSheetImg, armsSurfaceArray[j], &spriteCut,j,1 );
//blit.ApplySurface( 0, 0, background, armsSurfaceArray[j], NULL,0,1 );
//SDL_FreeSurface( background );
}
}
}
apply surface funtion used in above
void Surface::ApplySurface( int x, int y, SDL_Surface* source, SDL_Surface* destination, SDL_Rect* clip, int angle, int zoom)
{
SDL_Rect offset;
offset.x = x;
offset.y = y;
if (angle != 0)
{
source = rotozoomSurface(source, angle, 1, 1);
}
if (zoom != 1)
{
source = rotozoomSurface(source, 0, zoom, 1);
}
SDL_BlitSurface( source, clip, destination, &offset );
}
-------
EDIT;
doing some testing, there seams to be somthing inheritly wrong with what i am doing, this returns a blank surface, unless I dont use spriteCutTest (dont cut the image) then it works for about 60 frames then disapears, and stops loading the image (games speeds up)
SDL_Surface *Surface::PlayerIcon(int stride, string direction)
{
SDL_FreeSurface( background );
SDL_Rect spriteCutTest;
spriteCutTest.x = 20;
spriteCutTest.y = 20;
spriteCutTest.h = 200;
spriteCutTest.x = 400;
SDL_Surface *playerSpriteSheetImgTest = IMG_Load( "debug/Generic_Images/player_sprite_sheet.tga" );
blit.ApplySurface( 0, 0, playerSpriteSheetImgTest, background, &spriteCutTest,20,1 );
//blit.ApplySurface( 0, 0,torsoSurfaceArray[1][1], background, NULL,0,1 );
return background;
}
code that is puting the surfaces together;
void Surface::EntireDisplay(int playerHighLevel,SDL_Rect levelRect, string direction)
{
//map
SDL_Surface *levelDisplay = blit.VisualLevelSurface(levelRect);
blit.ApplySurface( 0, 0, levelDisplay, background, NULL,0,1 );
SDL_FreeSurface( levelDisplay );
SDL_Surface *personDisplay = blit.PlayerIcon(stride,direction);
blit.ApplySurface( 0, 0, personDisplay, background, NULL,0,1 );
SDL_FreeSurface( personDisplay );
//fliping, only place this should be
SDL_Flip( background);
SDL_FreeSurface( background );
}
